Notes about the RS485 serial bus for development purposes
• The same “Multifunction cable” (found in the CBL-1001-00 Cable Kit) you are using to supply power to the
PCN-1001, also allows you to connect the PCN-1001 to the RS485 port of the Host PC by using Cn4.
• Personal Computers generally do not have a RS485 port. You can use the “703704001SL Adapter” (an
element of the CBL-1001-00 Cable Kit) to connect Cn4 of the Multifunction Cable with the USB port of the
Host PC. The 703704001SL Adapter also integrates one termination resistors (120 Ohm) and two fail safe
resistors (560 Ohm). Refer to “ CBL-1001-00 cable kit” on page 100 before attempting to use the
703704001SL Adapter.

Notes:
• The 703704001SL Adapter includes the 120 Ohm termination resistors and the 560 Ohm fail safe resistors
• The “CDM 2.06.00 WHQL Certified” software (available on the CD-ROM) has to be installed on the Host
PC before connecting the 703704001SL Adapter. Visit the following websites for further software
