Figure 75: Transceiver 21–216
Only one setting is required for transceiver 21–216. It has to be set to external clock. Rotary
switch on the front panel pointing to position 0 indicates that external clock is selected. If
back-to-back testing is to be performed, one transceiver 21-216 has to be set as master by
setting the rotary switch to position 2 (overrides settings of jumpers 8 and 9). Clock
synchronization configuration using the rotary switch can be done on the fly.
