Raider Installation and Operation Rev. 1.4.2
TX Data Output - Pin 5
Connect the repeater TX Data Input to Pin 5. The transmit LTR data is adjustable from 0 to 1 volt
peak to peak. The output may be either AC or DC coupled depending on the transmitter used. DC
coupling is always preferable to AC coupling. With the TX DATA potentiometer fully "ON"
(clockwise) the DC voltage is between 4.2 and 4.8 VDC with up to 1 volt of AC data. Transmitters
designed to be DCS compatible are usually able to drive the modulator directly. After connecting
the Raider to the transmitter, the RF frequency should be checked and adjusted if necessary.
TX PTT Output - Pin 7
If the repeater PTT line is referenced between 10-14 volts, connect the repeater TX PTT Input to
Pin 7. The push-to-talk output can switch 300mA to ground through an FET transistor.
TX PTT Output - Pin 20
If the repeater PTT line is referenced to +5 volts or low voltages (below 10 volts), connect the
repeater TX PTT Input to Pin 20. Pin 20 is protected by an isolation diode.
Ground - Pin 25
Connect the cable ground to Pin 25. Be sure the Raider is secured to a properly grounded rack.
Power - Pin 13
Clean DC voltage (free of noise and transients) between 11 and 16 volts should be applied to Pin
13. The power received from the repeater or wall transformer that is capable of at least 1 amp will
work fine. The Raider draws 750mA or in the Low Power version, less than 300mA. Contact a
Trident Representative for Low Power or solar applications. If the DC voltage drops below 10 volts,
a low voltage reset circuit will interrupt the flow of current and the unit will not function. The Raider
will begin functioning again when the voltage rises above 10 volts.
Note:
The Raider has been
designed with a SECONDARY lightning protection system. If the site is located in an area where
lightning is a problem, make sure that good PRIMARY lightning protection is installed. Primary
protection of either
gas tube
or
carbon type
is recommended.
