Adapting the V.35 25-Pin D Connector on the UB-530 to the
UB-300 Pinout
The connectors on the UB-530 and UB-300 Universal Breakout Panels are identically
wired, except for the 25-pin D connector which, is used for the V.35 data interface. The
UB-530 uses a standard RS-530 pinout, while the UB-300 pinout is non-standard. The
following information describes how to adapt the UB-530 to the UB-300 pinout.
An adapter is added to the UB-530 breakout panel that converts to the UB-300 pinout.
Figure 2-2 illustrates the adapter that plugs directly into J3 of the UB-530, and
Table 2-3 provides the wiring information for conversion from RS-530 to the UB-300
pinout.
