Use with Satellite Modems

The V100 multiplexer is often used in combination with satellite modems to provide telecommunications
links between remote sites. This example describes the use of the V100 with a Paradise Datacom P300
modem that is fitted with the standard P1440 interface in RS422 mode, thereby allowing the use of the
standard RS422/RS449 cable (part number VI68723A, Appendix C4) at both ends of the link. It is also
applicable to the P400 modem when fitted with the P1448 interface, but in this case the cable number
VI68723B/P1448 should be used, to operate the interface in Direct mode. The standard cable should be
used with all other modems.
Disclaimer:
This example uses settings for the modems, which have been tested and proven to
work. There are other settings, which may be used according to the application. With
other manufacturers' equipment or when using other settings, the validity of this
example cannot be guaranteed.
The configuration concept is to use one unique clock in the system as generated by Modem0 (connected
to the V100 with Node I.D. "0"), with all other clocks derived from this:
The System settings for the units are as follows:
