Remote Outputs
Six (6) remote outputs, that indicate either the presence of various alarms or the status of operator
controlled circuits, are available for remote monitoring on the REMOTE I/O-B 9-pin male D-sub
connector on the rear panel of the transmitter (see Figure 1.7.1: on page 1.7.5). The sources and active
logic levels of these remote outputs are preset at Nautel. See Table 1.8.2 on page 1.8.5 for a list of the
factory preset outputs, their descriptions and their associated output pins on the REMOTE I/O-B 9-pin
male D-sub connector.
A switching device for each remote output, configurable through the front panel UI or remote AUI,
provides the desired active logic state, when a true condition exists.
For example, if a remote output is configured as Output Low When On (see the VX
Operations and
Maintenance Manual
for the specific text displayed on the front panel UI or remote AUI), then the
remote output’s switching circuit will provide a current-sink-to-ground when a logic true (on) condition
exists and an open collector for a logic false (off) condition.
Each switching circuit must present impedance between the switching device and a dc voltage source
that limits current flow to no more than 40 mA. Each circuit's positive voltage source must not exceed
23 V dc. The internal +15 V supply is capable of providing 100 mA for all active status outputs. If you
require more current capability, use an appropriate external power supply.
Remote Output Connections
Remote outputs 1 through 6, as required, connect to terminals of REMOTE I/O-B 9-pin male D-sub
connector on the rear panel of the transmitter. See Table 1.8.2 on page 1.8.5 to determine the output
pin associated with each remote output.
Nautel provides a D-sub mating connector (Nautel Part # JS223) and connector shell (Nautel Part #
JS225) in the Ancillary kit to facilitate customer connections to the controller, as applicable.
