1. Overview

 

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

0x81 = one 1dB step

0x82 = two 1dB steps

0x83 = three 1dB steps

0x84 = four 1dB steps

0x85 = five 1dB steps

0x86 = six 1dB step

0x87 = seven 1dB steps

0x88 = eight 1dB steps

0x89 = nine 1dB steps

0x8A = ten 1dB steps

The CAT 860 sends two <Param> characters in the response packet. The possible values are shown below:

<Param> #1:

0x80 = IR Channel A

0x81 = IR Channel B

<Param> #2:

0xCF = 0 dB 0xCE = -1dB 0xCD = -2dB 0xCC = -3dB 0xA7 = -40dB 0x83 = -76dB 0x82 = -77dB 0x81 = -78B 0x80 = -79dB

Definition: This command modifies the volume-level EEPROM variable which was selected by the IICH (<0xB0>) command. The EEPROM variable is incremented by the amount indicated in the <Param> character.

Afterwards, the value in the EEPROM variable is unconditionally loaded into the corresponding volume control hardware register. This overrides any prior mute operation.

If the command is properly received, the CAT 860 responds by repeating back the command packet where the first of two replacement <Param> characters contains the selection status set by IICH (<0xB0>) and the second contains the resultant value stored in the volume-level EEPROM variable which was modified by this command.

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

For the audio inputs, the power up default values for all six input volume-level EEPROM variables is set for -40dB.

Definition: This command modifies the volume-level EEPROM variable which was selected by the IICH (<0xB0>) command. The EEPROM variable is decremented by the amount indicated in the <param> character.
