AXC-232++ RS-232/422/485 Interface Card
Specifications (Cont.)
LEDs:
RX/TX: Red LED indicators for data transmission
RX: Red LED blinks to indicate that the AXC-232++ is receiving RS-232,
RS-422, or RS-485 data.
TX: Red LED blinks to indicate that the AXC-232++ is sending RS-232, RS-
422, or RS-485 data.
DIP Switch 8-position RS-232/422DIP switch.
See Setting the RS-232/422 DIP Switch section on page 4 for configuration
details.

Buffer • 1000 byte input buffer
• 1000 byte AXlink buffer
Internal jumpers Sets differential input termination to enable RS-485 output.
Processor 32-bit processor
Memory 384K of non-volatile memory (memory runs Axcess programs independent of
the master program. This relieves the AXlink bus and the master of the pro-
cessing time for controlling those devices; requires Axcess version 3.0 or
higher).
