2.10 Is Anyone Out There?
Before connecting any IEEE bus devices to the Micro488/EX, try this simple
operational check. The Micro488/EX must be configured for either System Controller
of Peripheral mode operation. This test will not work in either of the Pass-Thru modes.
Running BASIC on the host, or any programming language which supports the
serial ports, type the following (or its equivalent).
OPEN "COM1:9600,N,8,2,cd,ds" AS 1 [Return]
PRINT #1,"HELLO" [Return]
LINE INPUT #1,A$ [Return]
PRINT A$ [Return]
The Micro488/EX will respond with (and the host will display):
Micro488/EX Revision N.N Copyright (C) 1988 IOtech Inc.
where N.N is the release and revision number of the firmware.
If you obtain the above response then your Micro488/EX is alive and well and
ready to connect your host to the powerful IEEE-488 General Purpose Interface Bus. If
you did not receive the above message, check for proper connection and fit of the
interface cable. If, after reviewing the interface for proper installation, you do not
obtain the desired results then refer to the Service Information section of this manual.
