Appendix

C Special Serial Port Cabling

External Timing

If “External” timing is required to satisfy a particular application, Serial

Port #1 must be used (Worksheet Item #18) and

Serial Port #1 must

supply the master network timing (Worksheet Item #12). The worksheet

can be found on page 3-2.

External timing is used if the attached customer equipment is a DCE

instead of a DTE. The customer DCE must be configured so that its

Receive Clock is used for BOTH transmit and receive functions. This

clock is also delivered to the Serial Port’s External Clock input and drives

the Centum Series transmit function. Transmit and Receive Data must

also be reversed.
