---------------------------------------------------------------------------------------------------------------

intTmcInitialize( int wire, char* adr, int* id );

Purpose: Initializes and opens a connection to the specified device

Parameters: intwire connection types

char* adr the address of the connection

int* id special device ID used by other functions

Return value: 0 = OK, 1 = ERROR

Details:

Description of Parameters

int wire

Set this parameter to the type of connection through which the device will be

controlled.

The settings for each type of interface are shown below.

GPIB: wire = TM_CTL_GPIB(1)

RS232: wire = TM_CTL_RS232(2)

USB: wire = TM_CTL_USB(3)

Ethernet: wire = TM_CTL_ETHER(4)

USBTMC(DL9000): wire = TM_CTL_USBTMC(5)

EthernetUDP: wire = TM_CTL_ETHERUDP(6)

USBTMC(excluding DL9000): wire = TM_CTL_ETHERUDP(7)

VXI-11: wire = TM_CTL_VXI11(8)

char* adr

Use a character string to set this parameter to the GPIB address or RS-232

settings of the device to be controlled.

The following shows how the settings for each interface.

GPIB: adr = "1"-"30" (the GPIB address value of the device)

RS232: adr = "port number, baud rate number, bit specification, handshaking number"

port number 1 = COM1

2 = COM2

3 = COM3

baud rate number 0 = 1200

1 = 2400

2 = 4800

3 = 9600

4 = 19200

5 = 38400

6 = 57600

bit specifications 0 = 8 bits, no parity, 1 stop bit

1 = 7 bits, even parity, 1 stop bit

2 = 7 bits, odd parity, 1 stop bit

handshaking number 0 = NO-NO

1 = XON-XON

2= CTS-RTS

USB: adr = "1"-"127" (the unique USB ID for the device)

Ethernet: adr = "server name, user name, password"

sever name The server name or IP address of the DL

user name The user name

password The password

When the user name is anonymous,

a password is not required.

(A delimiting comma "," is required.)

USBTMC(DL9000): adr = "serial number"
