About your SD170E Series data radio
About Your SD170 Radio
The SD-170E Series of RF Link Modules utilize the latest technology in their designs and
manufacturing. SD-170E 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, in
these fully programmable RF Link Module units, to use FSK GMSK and FFSK modulation optional
boards are provided. 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 receiver (optional board).
To assure satisfaction from the radio, we urge you to thoroughly read the operation and function
information in this manual before operating your SD-171E/SD-174E.
Applications of some of the functions described in this manual are determined by the system you
use. Your dealer will program your radio 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 Dealer.

SD-170E Series Operation
Channel select / SCAN
Your radio’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 (4), you should open the upper cover and
then look for the DIP-S/W (4) on the digital board of the bottom cover. Once located change the
DIP-S/W to select wanted channel according to channel dip switch chart (see channel chart on
page 11).
To use a serial command for channel selection, it should be inputted by external equipment or
device (ex. Personal computer or PLC) through Pin 8 of DB-15 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 for transmission, normally, it’s released by Rx serial command. If RF activity is present;
it will not be illuminated if the radio indicates a “clear” channel. When the channel is “clear”, input
the PTT signal or TX serial command and transmit data or audio. Remove the PTT signal or input
Rx serial command when you have finished transmission.
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 from another radio or hear another person talking from the connected external
speaker.

Scan modes
Scanning is a dealer programmable feature that allows you to monitor a number of channels.
Your dealer will help you define a scanning mode and your channel “scan list”
Channel scan
Once the scan list has been established, initiate scan by serial commands. If a conversation is
detected on any of the channels in the scan list, the radio will stop on that channel and you will
be able to hear the conversation. At that time, busy channel data is sent to external equipment or
device through serial command. So, you can identify busy channel data as decoding of received
serial command from your radio in the external equipment or device.
Normally, if you try to transmit during scanning, the transmission will be made on the channel
that the call was received during the programmable scan delay time. The scan delay time is the
amount of time the radio will stay on that channel once activity has ceased. Dealer programming
of 4 ~ 7 seconds is typical). The radio will resume scanning once the scan delay time has expired,
and will continue to scan until the serial command for scan stop is inputted by external
equipment. After the scan resumes, if a transmission is made, the radio will transmit on the
selected priority channel. This feature is similar to priority scan TX except for selection of priority
channel. You can assign a priority channel by inner dip switch only.
Scan channel delete
To temporarily delete a channel from the scan list, simply input the serial command for scan
deletion to the radio while scanning and stopped on the channel to be deleted. This will
temporarily remove that channel from the scan list until the scan is closed or the radio’s power is
reset.
CTCSS / DCS Scanning
To help to block out unwanted calls to your radio, the SD-170E series can be programmed by
your dealer to scan for tones.
