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 radio.
Powering the data radio
Your data radio accepts many sources of DC power to permit more versatile use. This radio operates from 7.2V to 18V DC
and standard voltage for test is 12V DC.
Connecting the data radio to DC power
Connect DC power plug of power cable to radio’s DC IN power connector and then fasten power plug to the radio by
turning the ring clockwise.
SD-164 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 ( ), you should open the upper cover and then look for DIP-S/W( ) on the digital
board of bottom cover. After that, change the DIP-S/W to select wanted channel according to channel dip switch chart.
To use serial command for channel selection, it should be inputted by external equipment or device(ex. Personal computer)
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 as like 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 modem option board is installed). Basically,
TTL level is used as PTT signal and it’s low active. But, If you installed option modem board, you can use RS-232 level as
PTT signal instead of TTL level. To maintain transmission, continuous PTT signal input is required. But, if you use Tx serial
command for transmission, normally, it’s released by Rx serial command. Before the transmission, check the color of the
radio’s top-panel LED( ). It will glow orange 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. In case of dealer programmable, 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 priority channel by inner dip
switch only.
Scan channel delete
To temporarily delete a channel from the scan list, simply input serial command for scan deletion to the radio while
scanning and stopped on the channel to be deleted. This will remove that channel from the scan list until the scan is closed
or the radio’s power is reset. When scan restarts after close one time, all scan list are deleted, start scan after turn off or
turn on the power of the radio, the originally programmed scan list will be activated.
CTCSS / DCS Scanning
To help to block out unwanted calls to your radio, the SD-160 series can be programmed by your dealer to scan for tones.

Modem for data communication
Descriptions
A new kinds of internal Option-Modem are applied to SD-160 series. One is FFSK modem and the other is GMSK modem.
The most obvious method of increasing the efficiency is to maximize the data signaling speed in the limited channel
bandwidth. But, FSK has very wide transmission bandwidth requirement. To solve this problem, we will supply GMSK
(Gaussian Filtered Minimum Shift Keying) internal option-board.
In the case of data, its frequency spectra conflict with sub-audio frequency spectra. So tone squelch system is not
adaptable. If there is tone, only FFSK / MSK modem available and no GMSK modem is used.
Our internal Modem Option Boards consist of Slave MCU, Modem IC, and extra circuitry. This Option-Boards directly
communicates with DTE (Data Terminal Equipment) to send and receive the meaningful data through the D-sub connector.
Communication between DTE and Option-Board
These modem option boards support only asynchronous communication between DTE and modem option boards to
minimize loss of data during the transmission.
Your dealer will help you define a TX On/Off Delay time, RX On Delay time, Baud Rate, Modem Enabled, Modem Baud
Rate, RTS Control Mode, and Test Mode.

If GPS option board is installed in SD-160 series data radio, you can obtain your position data through GPS data output of
your radio (Pin 15 of DB-15 connector). Besides, you can transmit received GPS data to the other radio or base station
through modem if you install modem board with GPS board.
Your dealer will help you install GPS option board and define related parameter set-up.
