Construction and Functioning
3.3.3 ext. Interf.
The ext. Interf. (Pulse out 1) is the communication interface between the
CMGPS and the CMC test set.
Figure 3-10:
Communication
interface ext. Interf.
At this interface, the CMGPS is connected to the CMC test set by means of the
supplied connection cable (see figure 3-3 on page 14).
This interface serves to
• configure the CMGPS via software (e.g., the synchronization time)
• send the "Pulse out 1" synchronization pulse to the CMC test set.
Standardized factory setting of the synchronization pulse is 200 ms output once
per minute.
Note: This output is only to be used together with an OMICRON CMC test set.
Do not use this output for other devices or other applications.
