PTRL NV/3 & RXRL NV/3
5.3.7 Remote-control parallel port
At this port, some lines are brought to a male DB9 connector so the units can be
controlled directly through an external system controller. The lines are listed below:
5.3.7.1 Transmitter
- Pins 1, 5 and 8, ground.
- Pin 2, on-the-air signal: a high logic state (+ 12V with 10kW) indicates that the
transmitter is supplying significant RF power. This does not necessarily mean
that level is correct.
- Pin 3, forward power: signal proportional to forward power with pseudo-quadratic
like relationship. Variation range is 0-5Vdc with 1kW impedance. Full power
voltage is around 3.5-4 V.
- Pin 6, RF output disable: when this line is grounded, the RF output is disabled.
Maximum signal level is about + 12V/1mA.
- Pin 7, alarm: a low logic signal denotes an alarm. Correct operation is indicated
by +12V on 10kW. Maximum input current draw from an external source is limited
to <10mA.
- Pins 4 and 9, future expansion.
5.3.7.2 Receiver
- Pins 1 and 5, ground.
- Pin 2, "
modulation presence
" signal: a low logic state indicates that modulation
is present on the incoming signal; a high logic state (+ 12V with 10kW) denotes
no modulation. This option is software dependant and is not available on the
current software release.
- Pins 3 and 8, field indication sufficient. These pins are connected to the contacts
of a relay that is triggered by the incoming RF field. When the field exceeds the
preset threshold, the relay changes state. An internal jumper lets you determine
whether the relay is at rest with "
normally open (NO)
" or "
normally closed (NC)
"
contacts. Factory setting is "
NO
".
- Pin 6, unit disable: grounding this line disables the main outputs of BF and the
field indication relay. Maximum signal level at the pin is about + 12V/1mA.
- Pin 7, alarm: a low logic signal denotes an alarm. Correct operation is indicated
by +12V on 10kW. Maximum input current draw from an external source is limited
to <10mA.
- Pins 4 and 9, future expansion.
