AXB-PCCOM Communications Port Interface
Specifications
The following table details the specifications for the PCCOM.
DIP Switches
Communication Parameters
The AXB-PCCOM has these default configurations settings:
 Parity: None
 Stop Bits: 1
 Data Bits: 8
Use the Communication Parameters DIP switch to set the communications parameters. Switches 1
and 2 determine how many AXlink devices the PC device is emulating. Switch 5 enables the
hardware handshaking. Switches 6 through 8 determine the baud rate. Switches 3 and 4 are
reserved for future use. As an example, the DIP switch below (FIG. 2) defines four devices, a baud
rate of 9,600, with handshaking disabled.

Panel Components
RS-232 connector A DB-9 RS-232 connector used for communication with the PC for AMX
programming tools, such as Axcess and IRLIB.
TX LED (Red) Blinks to indicate that the AXB-PCCOM is transmitting data.
RX LED (Red) Blinks to indicate the AXB-PCCOM is receiving data. The RX LED blinks even
if the data is incorrect.
Communications Parameter
DIP switch
An eight position DIP switch used to set the number of AXlink devices
emulated, enable or disable handshaking, and set the Baud rate.
AXlink LED AXlink LED (green and blinks to indicate AXlink communication activity and
power:
• Full-Off indicates no power is being received or the controller is not
• functioning properly.
• One blink per second indicates power is active and AXlink communication is
• functioning.
• Full-On indicates there is no AXlink control or activity, but power is on.
AXlink connector This four-pin captive wire receives power and information via the AXlink bus
and AXlink system controller.
Device DIP switch An eight-position DIP switch used to set the AXlink device number for the
AXB-PCCOM.
