The final digit is for the ring code. Select from the following options:
0 – This will activate the latched monitor/squelch output, but produce no ringing tones. The momentary horn
output is disabled with this ring code.
1 – This will activate the latched and momentary outputs and produce a telephone like ring.
2 – This will activate the latched and momentary outputs and produce a pulsing ring tone.
4 – This will latch the horn output on until either the power is cycled or another sequence is decoded with a ring
code of 5. When using the horn output in a latched state the Monitor/Squelch Output is disabled.
5 – This will unlatch the horn output. When using the horn output in a latched state the Monitor/Squelch Output is
disabled.
8 – Turn off call lamp/mute. This resets the latched Monitor/Squelch Output.
9 – This will provide a latching output through Q7 that can only be reset by receiving the same sequence with this
ring code.
Register 7A – Set this register for either a 0 for Ground or a 1 for V+. This sets the Monitor Input Active Polarity.
Register 7B – Set this register for 00.
Register 7C – Set this register for .0-.9 seconds. This sets the length of time the transmitter will key-up for.
Register 7D – Set this register for 00.
Register 7E – Set this register for 0.
Register 8A – Set this register for .01-.99 seconds. This sets the decode time for the first tone in a decode
sequence. This time will also be applied to the second tone. The decode tone times should be set to
approximately 1/5 of the shortest encode time. Example: Motorola Quick Call 2 would be .20 for a 1 sec 3 sec
timing (20=200 ms).
Register 8B – Set this register for 00-99 seconds. This sets the length of time the unit rings when it decodes.
Register 8C – Set this register for 0-7. This sets the mode or tone the RT-2 will transpond in.
Register 8D – Set this register for 0-9 seconds. This field sets the time the momentary output will go to ground,
before going high again.
Register 8E – Set this field to 0 for ground or 1 for V+. This must match the squelch polarity of the radio, when
the radio is active. Squelch is controlled by the monitor input only.
Register 9A – Set this field to 00.
Register 9B – Set this field to 0.
Register 9C – Set this register to 0 for horn timeout in seconds and 1 for horn timeout in minutes. The horn
timeout is programmable for 0-9 in either 1 second or 1 minute increments depending on how this register is
programmed.
Register 9D – Set this field to 0.
Register 9E – Set this field to 0.
If all entries in a register are not completed, trailing zeros will be automatically entered. Extra digits will be
ignored. If the register is successfully programmed the unit will beep 2 times.
