Troubleshooting RS-232 Command Strings to TOA Products
December 04, 2012
By Rick Escobar - TOA Product Support Assistant Manager
One issue we hear from time to time is that "My Brand X" controller cannot control a TOA product by sending RS-232 commands. For this example, let's refer to a 9000M2 series Matrix / Mixer Amplifier (for you references download this document "9000M2 RS232C Protocol Manual" by clicking here).
We'll skip the low level detail and get to the point on how to make your control surface work for you. The 9000M2 is looking for a hexadecimal string that it will read then react to the instructions sent. Here is an excerpt from the "9000M2 RS232C Protocol Manual":
5.5 Power ON/OFF
This command performs ON/OFF setting of the power switch of the 9000M2 Series
Amplifier. 9000M2 Series Amplifier responds with the same data as that received.
F4H, 01H, < ON/OFF >
Example 1: Setting the power switch to OFF
F4H, 01H, 00H
Example 2: Setting the power switch to ON.
F4H, 01H, 01H
And so forth.
Good Luck and Happy RS-232 Programming!
