IOtech GPIB Command Associated MCC GPIB 488.2 Command(s)

PPollConfig PPollConfig

Syntax

PPollConfig {IOtech} INT WINAPI PPollConfig(DevHandleT

devHandle,BYTE ppresponse);

PPollConfig {

MCC} PPollConfig(int board, short address,

int dataline, int sense)

Usage Notes

IOtech’s PPollConfig command was used to configure the Parallel Poll response of a

specified bus device. Not all devices supported Parallel Polling; among those that did, some

still did not support the software control of their Parallel Poll response. Some devices were

configured by internal switches.

MCC’s PPollConfig command is used to configure a device for parallel polls.

Note: If a device is locally configured for a parallel poll, then the Controller's parallel poll

configuration instruction is ignored.

In the following example, the command configures the device connected to board 0 at address 6

to respond to parallel polls on line 7 with sense 1. The device asserts line 7 if its IST bit = 1,

and unasserts line 7 if IST = 0.

Example: PPollConfig(0, 6, 7, 1)
