Initial Operation
Use the following program example to verify initial Microwave Switch
operation by closing a channel and querying channel closure. The example
first resets the switchbox and then closes channel 02 of a single Microwave
Switch module (card number 1) in the switchbox. The program next queries
the channel closure state. A returned "1" shows that the command to close
the channel has been sent to the switchbox. A returned "0" shows that the
command to close the channel has not been sent to the switchbox.

Switch module (card number 1) in the switchbox. The program next queries

the channel has been sent to the switchbox. A returned "0" shows that the
command to close the channel has not been sent to the switchbox.
The computer used in the example is an HP Series 200/300 computer with
HP BASIC as the program language. The computer interfaces to the
mainframe using the Hewlett-Packard Interface Bus (HP-IB).* The HP-IB
interface select code is 7, the HP-IB primary address is 09, and the HP-IB
secondary address is 15. Refer to the HP 75000 Series B Installation and
Getting Started Guide for addressing information.
