Introduction
Many audiovisual and computer-based devices can be remotely controlled using RS-232, RS-422,
or RS-485 commands. The AXC-232++ RS-232/422/485 Interface Card can generate virtually
unlimited numbers of product/function commands as they are programmed into the AXC-EM
Master Card. As needs and technology change, existing cards can be reprogrammed or new cards
added, one for each device.
One AXC-232++ card (FIG. 1) is required for each RS-232/422/485 controlled piece of equipment.
The AXC-232++ card has a DIP switch to set communications parameters (data bits, stop bits,
parity, and baud rates from 300 to 115,200 bps).
FIG. 1 AXC-232++
Onboard processing and memory allows the controller to take on complex tasks by itself, reducing
the processing burden for the AXlink master program. For example, the master program can use
simplified commands for generic video switcher or codec control, while a modular driver program
in the AXC-232++ handles control for specific makes and models.
