3. Multiplexed Mode Setup
First Address
Choices: Group 1 to Group 15
Default: Group 1
Selects an additional address (different from a broadcast address) to receive the AUX I/O data. The data that comes with this address value is transmitted to this I/Q channel.
This setting is inactive (grayed out) unless Multiplexed is the AUX IO operating mode.
Second Address
Choices: Group 1 to Group 15
Default: Group 2
Selects another additional address (different from a broadcast address) to receive the AUX I/O data. The data that comes with this address value is transmitted to this I/Q channel.
This setting is inactive (grayed out) unless Multiplexed is the AUX IO operating mode.
