Installation Guide
The Comm Board provides the external link from master controller to host PC. Comm Boards are only needed for the
master controller for each site. The Comm Board provides communication via either RS-232 serial/direct-connect,
modem, or USB. For Ethernet/LAN communications a LAN-520 is still required (replacing the Comm Board).
NOTE: The Comm Board can be used by any PXL family controller except the PXL-250.
