TS-32/TS-64 hookup
Connector JTS32 is a 7-pin header that allows the easy installation of an optional
Communications Specialists TS-32 or TS-64 for CTCSS decode, encode, CTCSS audio
filtering, and reverse-burst. (Reverse burst is only available with the TS-64.) Wire JTS32 to
the TS-32/TS-64 as follows:
JTS32 Connections

Signal
Description
1 +V POWER +10 volts to CTCSS board
2 CTCSS DECODER INPUT receiver audio to CTCSS decoder
3 TO AUDIO FILTER INPUT
receiver audio to audio filter input
(separate lead for TS-64)
4 FROM AUDIO FILTER OUTPUT filtered audio to controller
5 CTCSS DETECT
decode signal from CTCSS decoder
See important warning below!
6 CTCSS ENCODER OUTPUT CTCSS tone to transmitter
7 - GROUND & HANG-UP Ground
WARNING:
DO NOT APPLY VOLTAGE TO THE CTCSS DETECT INPUT!
This input is pulled low by the CTCSS decoder when CTCSS is NOT PRESENT. It will float high
when CTCSS is detected. Application of voltage to this input will destroy Q4 and render the
controller inoperative. Damage of this nature is not covered by the NHRC Limited Warranty.
The TS-32 and the TS-64 both have a high-pass filter to remove the CTCSS tone from the
repeated audio. By removing jumper JP3, the controller's audio can be passed through the
audio filter on the TS-32/TS-64.
Note: If the audio filter is not used, then jumper JP3 must be installed in order for audio to
be passed through the controller.
The Communications Specialists CTCSS boards are not supplied by NHRC. Contact
Communications Specialists at 800-854-0547 directly to order these boards.
2.3.1 TS-64 Notes
Consult the NHRC-4/M2 TS-64 Application note for detailed connection instructions.
The TS-64 has a reverse-burst/PTT delay feature that can be used with the NHRC-4/M2.
This feature is useful to eliminate the squelch crash received by the user's radio when the
repeater transmitter drops. Note that the user's radios must have CTCSS decoding enabled
for this to work. The NHRC-4/M2 provides support for the PTT delay through jumper JP4.
JP4 pin 1 is the controller's PTT signal, and JP4 pin 2 is PTT to the MASTR II. If the
reverse-burst/PTT delay feature is not used, then a jumper must be installed on JP4 so the
controller can key the MASTR II.
