Overview

The controller sends only one <Param> character in the command packet. The possible values are shown below:

0x80 = TV/VCR**

0x81 = CD/DVD

0x82 = COMPUTER

0x83 = AUX IN

0x84 = IR Channel A

0x85 = IR Channel B

0x86 = AUX OUT

Definition

This command determines which volume-level will be affected by the AIDI (<0x92>), AIDD (<0x93>), and AIAV (<0x94>) commands.

If the command is properly received, the CAT 860 responds by repeating back the command packet where the <Param> character contains the selection status.

If the command is not received properly, the CAT 860 responds by sending a <NACK> character.

Power up default is TV/VCR selected.

These items are included for controllers limited to only a single volume control, the three parameters on the left allow the AIDI (<92>), AIDD (<93>), AIAV, (<94>) and AIAV? (<95>) commands to have the same capabilities as the AODI (<A2>), AODD (<A3>), AOAV (<A4>), AOAV? (<A5>), IIDI (<B2>), IIDD (<B3>), IIAV (<B4>), and IIAV? (<B5>) commands.

That is, multiple commands will be able to independently affect the values of the same volume-level EEPROM variables which correspond to the IR CH-A, the IR CH-B, and the AUX OUT. This is true even if the two commands have been directed to the same volume-level EEPROM variable. In this case the EEPROM variable retains the value from the last command issued from the serial controller.
