About your SD-170EX Series Data Radio
The SD-170EX Series of RF Link Modules utilize the latest technology in their designs and manufacturing. SD-170EX
models are Phase Lock Loop Synthesizer (PLL) / microprocessor controlled and offers 1/ 5 watt (Low / High) programmable
output power with 16-channel capability. Multiple functions including 1200 to 9600 baud rates, AC and/or DC audio
coupling, GMSK, FFSK and FSK modulation are standard in these fully programmable RF Link Module units.
Programmable sub - audio squelch system (CTCSS & DCS) and two-tone squelch system are added to the signal level
detect squelch system (RSSI). GPS Data handling is provided to interface and control an internal GPS r eceiver.
To assure satisfaction from the radio, we urge you to thoroughly read the operation and function information in this manual
before operating your SD - 171EX/SD - 174EX.
Applications of some of the functions described in this manual are determined by the system you use. Your radio may be
programmed so that you have the greatest number of functions possible relative to your needs.
Should you have questions regarding the operation of the radio, please consult your Deale r and/or Maxon Australia .

Antenna installation
Fasten the antenna to the radio by turning the antenna cable clockwise into the receptacle on left of radio when looking at
front of r adio.
Powering the data radio
Your data radio accepts many sources of DC power to permit more versatile use. This radio operates from 9.0V to 18V DC
and standard voltage for test is 12V DC.

SD-170EX Series Operation
Channel select / SCAN
Your r adio ‟ s channel can be selected by inner DIP-S/W or serial command inputted from external control system. To change
channel by inner DIP-S/W (%), you should open the upper cover and then look for the DIP-S/W(%) on the digital board of
the bottom cover. Once located, change the DIP-S/W to select wanted channel according to channel dip switch cha r t.
To use a serial command for channel selection, it should be inputted by external equipment or device (ex. Pe r sonal
computer) through Pin 8 of DE-9 connector. See the message format for serial command for full details.
If your radio has been programmed the channel scan, you must enter the scan mode by serial command.
Transmit
The transmission will be made by various inputs such as PTT signal (Pin 3 of DB-15 connector), TX serial command and
Serial data input (Pin 10 of DB-15 connector: This input is only available when a modem option board is installed). TTL level
is used as PTT signal and is active low. If you installed an option modem board, you can use RS-232 level as a PTT signal
instead of TTL level. To maintain transmission, continuous PTT signal input is required. If you use Tx serial command fo r
transmission, normally, it ‟ s released by Rx serial command. If RF activity is present; it will not be illuminated if the r adio
indicates a “clear” channel. When the channel is “clear”, input the PTT signal or Tx serial command and transmit data o r
audio. Remove the PTT signal or input Rx serial command when you have finished t r ansmission.
CAUTION : Operation of the transmitter without a proper antenna installed may
result in permanent damage to the radio.
Receive
When you have finished transmission, remove the PTT signal or input Rx serial command. You will receive data f r om
another radio or hear another person talking from the connected external speake r .
