4.2.3.1 Generic I/O Interconnect Breakout Cable
All communication to the main RVP902 server chassis is over an Ethernet cable. Also, two
general purpose I/O ports on J3 and J6 provide additional system control and monitoring.
The major volume of data is the I and Q samples and some status indicators.
A generic interconnect cable is available to breakout each of the 51-pin micro D connectors
on the IFDR to a standard 25-pin and 37-pin female D connector. A similar 62-pin cable is
used with IO62 card.
The following table shows the cable wiring and internal signal names. The cable provides 10
RS-422 signals, 10 TTL signals, three
dierential analog input A/D signals, and +5 V and -5 V
auxiliary power from the IFDR. Standard cable length is 1 meter.
J3 and J6 are identical ports each providing the following signals.
