You may then order as many packages as you require from your local Tait Company .Revision packages are supplied ready-punched for inclusion in your manual.Revision ControlEach page in this manual has a date of issue. This is to comply with various Quality Standards, but will also serve to identify which pages have been updated and when. Each page and its publication date is listed in the "List of Effective Pages", and a new list containing any new/revised pages and their publica-tion dates will be sent with each revision package.Any portion of text that has been changed is marked by a verti-cal line (as shown at left) in the outer margin of the page. Where the removal of an entire paragraph means there is no text left to mark, an arrow (as shown at left) will appear in the outer mar-gin. The number beside the arrow will indicate how many para-graphs have been deleted.The manual issue and revision status are indicated by the last three digits of the manual IPN. These digits start at 100 and will increment through 101, 102, 103, etc., as revision packages are published, e.g:Thus, Issue 103 indicates the third revision to issue 1 and means that three packages should have been added to the manual. The issue digit will only change if there is a major product revision,or if the number of revision packages to be included means that the manual becomes difficult to use, at which point a new issue manual will be published in a new ring binder.PCB InformationPCB information is provided for all current issue PCBs, as well as all previous issue PCBs manufactured in production quanti-ties, and is grouped according to PCB. Thus, you will find the21 0 3issue statusrevision status4M800-00parts list, grid reference index (if necessary), PCB layouts andcircuit diagram(s) for each individual PCB grouped together.

When requesting this infor-mation, please quote the equipment type number (e.g. T807-10) and serial number. In the case of the Service Manual quote the Tait Internal Part Number (IPN), e.g. M800-00-100, and for circuit diagrams quote the 'Title', 'IPN' and 'Issue'.1.1Caution: CMOS DevicesThis equipment contains CMOS Devices which are susceptible to damage from static charges. Care when handling these devices is essential. For correct handling proce-dures refer to the manufacturers' data books, e.g. Philips data books covering CMOS devices, or Motorola CMOS data books, Section 5 'Handling', etc.Figure 1.1 Typical Antistatic Bench Set UpAn antistatic bench kit (refer to Figure 1.1) is available from Tait Electronics Ltd under the usual consumable goods ordering system. The kit is held in stock under IPN 937-00000-34 and contains:• 1 conductive rubber bench mat• 1 earth lead to connect the mat to ground (c/w 1M series resistor)• 1 wrist strap•information leaflet.conductive rubber bench matmetal frameto building earth(not mains earth)via 1M series resistor conductivewrist strapA1.2General M800-00 1.2Caution: Beryllium Oxide & Power TransistorsThe power transistors in current use all contain some beryllium oxide. This substance, while perfectly harmless in its normal solid form, can become a severe health hazard when it has been reduced to dust. For this reason the power transistors should not be broken open, mutilated, filed, machined, or physically damaged in any way that can produce dust particles.M800-00Mechanical A2.1 2Mechanical2.1Pozidriv Recess Head ScrewsPozidriv recess head screws are the preferred standard on all Tait manufactured equip-ment. The very real advantages of this type of screw will not be realised unless the cor-rect screwdrivers are used by servicing personnel.2.2Disassembly/ReassemblyInstructions on disassembly/reassembly for individual equipment are given in the rele-vant part of this manual.A2.2Mechanical M800-00M800-00Component Replacement A3.1 3Component Replacement3.1Leaded ComponentsWhenever components are removed from or fitted to a PCB, care must be taken to avoid damage to the track. The two satisfactory methods of removing components from PTH PCBs are detailed below.Note:The first method requires the use of a desoldering station, e.g. Philips SBC 314 or Pace MBT-100E.3.1.1Desoldering Iron MethodPlace the tip over the lead and, as the solder starts to melt, move the tip in a circu-lar motion.Start the suction and continue the movement until 3 or 4 circles have been com-pleted.Remove the tip while continuing suction to ensure that all solder is removed from the joint, then stop the suction.Before pulling the lead out, ensure it is not stuck to the plating.If the lead is still not free, resolder the joint and try again.Note:The desoldering iron does not usually have enough heat to desolder leads from the ground plane. Additional heat may be applied by holding a sol-dering iron on the tip of the desoldering iron (this may require some addi-tional help).3.1.2Component Cutting MethodCut the leads on the component side of the PCB.Heat the solder joint sufficiently to allow easy removal of the lead by drawing it out from the component side: do not use undue force.Fill the hole with solder and then clear with solderwick.A3.2Component Replacement M800-00 3.2Surface Mount DevicesCaution:Surface mount devices (SMDs) require special storage, handling,removal and replacement techniques. This equipment should be serv-iced only by an approved T ait Dealer or Service Centre equipped withthe necessary facilities. Repairs attempted with incorrect equipment orby untrained personnel may result in permanent damage. If in doubt,contact T ait Electronics Ltd or your nearest T ait Branch or Subsidiary.M800-00To Remove Cased Mica Capacitors A4.1 4To Remove Cased Mica CapacitorsCased mica capacitors can be removed by heating the top with a heavy-duty soldering iron and gently lifting the capacitor off the PCB with a solder-resistant spike or equiva-lent.A4.2To Remove Cased Mica Capacitors M800-00M800-00Software History A5.1 5Software History23/11/89BASEPROG V ersion 123/08/90PGM800 V ersion 211/06/91PGM800 V ersion 2.0103/10/95PGM800 V ersion 2.2128/06/96PGM800Win V ersion 1.0018/08/97PGM800Win V ersion 2.005.1BASEPROG V1/PGM800 V2T800 programming software was originally developed as BASEPROG V1 and released as PGM800 V2.5.2PGM800 V2.01The major changes introduced with V2.01 are as follows:•Full support for different display adaptors.•Programming of CTCSS frequency data (optional) for individual channels.•Full cursor control in edit mode.•User selectable output file format (hex or binary).•Support for wider range of T800 equipment.•DOS shell facility implemented.•CTCSS defeat possible when CTCSS tone is not selected.•Channel numbering changed from 0-127 to 1-128.•An "X" included on the printout to indicate that there are 8 switches on the DIP switch and the state of the MSB is dependent on the size of the EPROM used.

Servicing:Refer servicing to qualified technical personnel only.INTRODUCTIONThank you for purchasing the ART T8 Universal Eight Channel Transformer Isolator. This is a rock solid, road-worthly 8 channel transformer isolator. “Hum” in an audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60Hz ( or higher harmonic) hum created by electrical wiring. Typically, these loops are connected via grounds, more commonly called “ ground loops”. The safest way to eliminate unwanted noise is with the T8.The T8 is a quality totally passive audio interface that uses eight high performance low distortion transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The T8’s audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the T8 a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed for use with impedances from 600 Ohms to 100k Ohms.What further sets the T8 apart from other lesser isolation boxes is its connection versatility. We have provided XLR, ¼” phone, and RCA type phono connections on all inputs and outputs. This allows it to easily fit into virtually any audio system and be the clean patch point between all types of systems. All ¼” and RCA phono jacks are on the front and all XLR jacks are on the rear. You can use any combination and since the jacks are directly paralleled you can also use them as signal taps or as a signal splitter.The T8’s mounting ears are reversible so you can have either the ¼” and RCA phono jacks on the front or the XLRs on the front. This maximizes flexibility in cabling your system. Whether you need an interface between a computer based audio workstation and your monitor system, isolation on long cable runs in a fixed installation, isolation of multiple signal sources from your recording equipment, or in many cases, just a safer connection between two audio systems, the T8 can accommodate. The 19” 1U black all steel case and its all passive design allow the T8 to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually any PA application. It is equally valuable in a variety of studio and AV applications. Its full feature set, rugged construction, and high-end specifications make the T8 the obvious choice.APPLICATIONS:LIVE SOUND, D.J.Long unbalanced cables are more susceptible to picking up hum , Using the T8 to help balance these and eliminate any hum.When DJs set up for different jobs there is a potential to pick up hum due to the differences in house wiring, using a T8 Eliminates the potential for hum.MIXERS/FIXED INSTALLS/RECORDING/BROADCAST/VIDEOUse the T8 to eliminate ground loops when using multiple mixers.Taking mixer unbalanced sends and achieving true balanced monitor outputs.Using the T8 between video/broadcast rigs eliminates the potential for hum and loop noise.POWER AMPLIFIERSHum, ground loop noise can be created between multiple amplifiers. This can be eliminated using the T8 on each of the amplifiers input lines.COMPUTERSUsing a T8 can eliminate unwanted ground loops created between the computers and your audio input equipment.You can also use the T8 to balance the unbalanced inputs and outputs from your computers sound card.WARRANTY INFORMATIONLimited WarrantyApplied Research and Technology will provide warranty and service for this unit in accordance with the following warrants:Applied Research and Technology, (A R T) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of three years from the date of purchase.

Make sure the power adapter is connected to the POWER port.Step 3. The POWER indicator light and theINPUT 2 indicator light should turn ON. Step 4. Connect the SW1956CT inputs to theoutputs of the DA1930CT VGA+AUDIO to CAT-5/6 Transmitters. Step 5. Connect a cable from the output port ofthe SW1956CT to the input port of the DA1931CT CAT-5/6 to VGA+AUDIO Receiver. Step 6. If the remote control switch is to be used,connect the RC5203CC to the INPUT SELECT port.CAUTION: The POWER port and the INPUT SELECT port use the same connector type. Make sure the control switch is connected to the INPUT SELECT port.Step 7. Verify that the picture quality on thedisplay is good. If a signal is not being received, make sure that the display is compatible with the resolution of the computer graphics card.There are no settings to adjust on the SW1956CT Auto-Switcher. The SW1956CT will operate successfully as long as cables are attached properly and other technical specifications are followed.AUTO-SWITCH MODEThe SW1956CT automatically selects the INPUT 2 port if there are no active signals present. If there is an active signal on INPUT 2 and not on INPUT 1, then the SW1956CT will maintain INPUT 2 as the active port. However, when an active signal is applied to INPUT 1, the SW1956CT will switch to INPUT 1.If there are active signals on INPUT 1 and INPUT 2, the SW1956CT will automatically switch to INPUT 1.MANUAL SWITCH MODEManual override is accomplished via a contact closure on the INPUT SELECT jack. Manual Switch Mode disables Auto-Switching.Included with the SW1956CT is an external manual switch with a six foot cable, Altinex part number RC5203CC . This switch may be used for manual control, or the contact closure may be made from a control system. This port uses a 2.5mm mini-coaxial remote control jack and it is located next to the CAT-5 OUTPUT.INPUT 1 will be selected when the remote control switch is connected to the INPUT SELECT jack and the contact is closed. INPUT 2 will be selected if the contact is open.CAUTION: The connector used for the INPUT SELECT port is the same type as is used for the POWER connector. Use caution to ensure the switch is connected to the correct port.88We have carefully tested and have found no problems in the supplied SW1956CT unit. However, we would like to offer the following suggestions:8.1 THE POWER LED IS OFFCause 1: The power adapter is installedwrong. Solution 1: Make sure the adapter output isconnected to the POWER input jack on the unit. Check the unit carefully. The POWER input jack and the INPUT SELECT jack are the same type. If the POWER LED is still not on, see Solution 2. Solution 2: Make sure the adapter is pluggedinto a proper AC outlet that has power. If the adapter has AC power and the POWER LED is still off, see Cause 2. Cause 2: The wrong power adapter isinstalled. Solution 1: Please use the Altinex suppliedexternal adapter (9V, 500mA). If the POWER LED is still not on, please call ALTINEX at (714) 990-2300. 8.2 UNIT DOES NOT AUTO-SWITCHCause 1: The manual override switch isinstalled. Solution: Remove the connection to theINPUT SELECT jack on the unit. If a plug is installed in the jack, even without a switch, the unit will not auto-switch properly. If the unit does not auto-switch with the plug removed, see Cause 2. Cause 2: The signal is not active or isimproperly formatted. Solution 1: Remove the input signals from theswitcher. If the IN 2 LED is OFF, call ALTINEX at (714) 990-2300. If the IN 2 LED is ON, see Solution 2. Solution 2: Connect a properly formatted signalfrom an Altinex CAT-5/6 Transmitter to INPUT 1. If the switcher does not switch to INPUT 1, see Solution 3. Solution 3: Bypass the switcher and connect theoutput of the transmitter directly to the input of the receiver. If the display is good, then call ALTINEX at (714) 990-2300. 8.3 NO DISPLAYCause 1: The source has a problem. Solution: Check the source and make surethat there is a signal present and all source connections are correct. If the source is working and there is still no display, see Cause 2. Cause 2: Manual override is ON.Solution: Make sure there is nothingconnected to the INPUT SELECT port on the switcher. If there is nothing connected, see Cause 3. Cause 3: Signal is bad or missing.Solution 1: Make sure the switcher output isconnected to the CAT-5/6 Receiver input and the receiver is ON. If there is still no display, see Solution 2. Solution 2: Remove both inputs to the switcherand connect the active signal form the CAT-5/6 Transmitter output to INPUT 2. If there is still no display, see Solution 3. Solution 3: Bypass the switcher and connect theoutput of the transmitter directly to the input of the receiver. If the display is good, then call ALTINEX at (714) 990-2300. If there is still no display, see Cause 4.9Cause 4: Cable connections are incorrect. Solution: Make sure that cables are properlyconnected. Also, make sure that the continuity and wiring are good. If there is still no display present, see Cause 5. Cause 5: The display has a problem.Solution: Make sure the display has powerand is turned ON. If there is still no display, please call Altinex at (714) 990-2300.99.1 LIMITED WARRANTY/RETURN POLICYPlease see the Altinex website at for details on warranty and return policy.9.2 CONTACT INFORMATION ALTINEX, INC 592 Apollo street Brea, CA 92821 USA TEL: 714 990-2300TOLL FREE: 1-800-ALTINEX WEB: E-MAIL: *********************。
