F.8.1 RCP902 WSR98D I/O Interconnect
Breakout
The interconnect cables breakout each of the 51-pin micro "D" connectors
on the IFDR into standard 62-pin female "D" connectors to the RCP902
WSR98D panel. Table 31 and Table 32 provide the cable wiring and
internal signal names on the IFDR and WSR98D. The standard cable
length is 2 m.
If extending the length of this interface by additional cabling, a cable with
good isolation between the twisted signal pairs is required to maintain the
signal integrity, guarantee valid logic levels on TTL signals, and low noise
on analog signals. The Vaisala provided wire meets the MIL-DTL-
22759/11 specification, which is insulated with PTFE. If additional
shielding between wire pairs is feasible it should also be considered.
