Turn On Volume - Russound CAS44 Manual

7.8 Turn On Volume

Turn On Volume levels displayed on keypads range in value from 0 – 100 in steps of 2 (i.e. 0, 2,
4 ... 100). These Turn On Volume levels are represented in Decimal when using RS-232
messages ranging in value from 0 - 50. In the actual Data message the HEX value is used which
would range in value from 0x00 – 0x32. This means (0x00 = 0 = 0, 0x01 = 1 = 2, 0x02 = 2 = 4
... 0x32 = 50 = 100)
NOTE: The keypad displays will not automatically update for this change.
7.8.1 Increase or Decrease Turn On Volume
The following example shows the Turn On Volume level being increased or decreased.
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
Value F0 cc 00 7F 00 00 70 05 05 02 00 zz 00 04 00 bb 00 00 00 00 00 01 xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
7.8.2 Set Turn On Volume
Select the Turn On Volume level for a particular zone using a discrete message.
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
Value F0 cc 00 7F 00 00 70 00 05 02 00 zz 00 04 00 00 00 01 00 01 00 ## xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
Byte #22 = Turn On Volume level (0x00 - 0x32, 0x00 = 0 ... 0x32 = 100)
7.8.3 Get Turn On Volume
The current Turn On Volume for a particular zone can be obtained using the following message.
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Value F0 cc 00 7F 00 00 70 01 05 02 00 zz 00 04 00 00 xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
The return message would look like the following.
Byte # 1 2 3 4
Value F0 00 00 70 cc 00 7F 00 00 04 02 00 zz 01 00 00 00 01 00 01 00 ## xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
Byte #22 = Turn On Volume level (0x00 - 0x32, 0x00 = 0 ... 0x32 = 100)
10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
