5.1.8—RS-232 Service Port
An isolated RS-232 service port is located on the front of the CPU module. This
port is for VxWorks
®
* operating system use only and cannot be configured for
application software use. The communication settings are fixed at 38.4 Kbaud, 8
data bits, no parity, 1 stop-bit, and no flow control.
*—VxWorks is a trademark of Wind River Systems, Inc.
For debug use, a null-modem cable and 5450-1065 Serial Adapter cable (PS2M
to DB9F) is required to attach this port to a PC. This port is to be used by trained
Field Service personnel only!
Shielded cable is required when connecting to the Service Port. Using shielded
cable will help ensure the robustness of the serial communications.
Pin 1 – RS-232 Receive
Pin 2 – RS-232 Transmit
Pin 3 – Signal Ground

5.1.9—CAN Communication Ports
Two CAN ports (M12 male connectors) are available for communication with
other Vertex-Pro controllers. A maximum of three Vertex-Pro configured for
operation using compressor load sharing may be used. When using redundant
CPU modules and a failover occurs, each CAN port automatically performs a
failover from the SYSCON to the STANDBY CPU module.
Note:
If CAN or GS6 operation is required in an expansion rack, a CPU module
must be used in place of the Remote RTN module.
Pin 1 – CAN Shield (AC coupled)
Pin 2 – not used
Pin 3 – CAN Signal Ground (black)
Pin 4 – CAN High (white)
Pin 5 – CAN Low (blue)

CAN networks must include 120
Ω terminations at each end of the trunk line.
Drop cables connecting a device to the trunk line should be as short as possible
and less than 6 meters. It is recommended to design the network to be less than
100 meters with a max cumulative drop length of less than 39 meters.
