Integra T Technical Manual
2.4 Rear 
Panel
 
 
Figure 9 – Integra-T rear panel
 
The various elements are described in the fol-
lowing sections.
2.4.1 Heat 
Sink
 
The rear panel heat sink is essential for proper
operation of the Integra-TR transmitter. The unit
must be mounted in a location that permits free
air circulation past the heat sink. Cooling will be
best if the fins are vertical.
2.4.2 
Power / Analog connector
 
The 4 pin power / analog connector pinout is
shown below:

2.4.2.1 Power
 
Integra-TR’s power requires a filtered power
source  of 13.3 VDC nominal (10 – 16 VDC
max.), negative ground with a 3.0 A rating.
 
An internal 3A fuse (surface-mount and not
field-replaceable) and a crowbar diode protect
the main RF power components from reverse
polarity. Application of more than 16 VDC will
damage the unit and is not covered by the war-
ranty.
 
WARNING: Do not exceed 16Vdc.

2.4.2.2 Analog 
inputs
 
Two analog inputs are provided. Inputs are
scaled to 0–10 V and have a resolution of 8 bits
(1 part in 256). Inputs are referenced to chassis
ground.
 
The absolute maximum input voltage should be
no greater than 20 Vdc. These inputs are re-
verse-voltage protected.
 
Integra-TR allows the analog values to be read,
either locally or remotely, using the Offline Di-
agnostics function of the Integra RDS.
 
Analog in 2 (pin 4) can be switched (using the
Integra RSS) to perform as the demodulated sig-
nal level test point (RX-TP) which is half of the
voltage read at the RSSI bar graph.
If the analog inputs are not used, the green and
white wires should be cut back and/or taped to
prevent contact.
2.5 Operation
 
Integra-TR is designed for fully transparent op-
eration. This means that all binary values are
transmitted as data, with minimum time delays,
and without regard to their binary value.
“Break” signals can also be transmitted.
