Channel Setting Commands
The AXB-IRS4 channel settings listed in the following table set IR output channels. The AXB-
IRS4 can process up to two IR or serial device channel setting commands simultaneously. If more
than two device commands are sent simultaneously, only the first two devices receive the
commands. The AXB-IRS4 can also be controlled with older SX-DCU+ RS-232 protocols.
Send Commands
The send commands listed in the following table send software strings to the AMX system, and
they are interpreted into a command and performed. The AXB-IRS4 can store up to 24
simultaneous CH, CP, SP, CTON, and CTOF send commands. Each command is stored and
transmitted to the appropriate channel when it becomes available.
