Figure D-11 RS530 Null-Modem Cable
The connecting cable must be a shielded cable.
Circuits which are paired (contain an (A) and (B) reference) should be connected to
twisted pairs within the connecting cable.
This cable is needed when it is necessary to connect two units back-to-back and a set of
modems is not available. Note that this cable specifies DB25 connectors on each end to
allow direct connection to the link interface connector on each unit. The link speed
must be defined for each of the two units.
