About your SD-170E Series Data 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,

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 receiver.

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.

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 9.0V to 18V DC

and standard voltage for test is 12V DC.

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 (q), you should open the upper cover and then look for the DIP-S/W(q) 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.

To use a 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 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.

Audible alert tones

Your SD-170E series data radio has a sophisticated microprocessor control which provides a range of audible tone. If you

connect the Speaker filtered OUT (Pin 9 of DB-15 connector) to an external speaker, you can hear audible tones at the

following conditions:

• Attempt to transmit on a channel that is already in use when busy channel lockout has been programmed into the radio

• Transmission time has exceeded time-out timer programmed length

• When the other group or people finished transmission using repeater

See the status audible alert tones chart for full details.

Modem option for data communication

DESCRIPTION

The ACC-513E and ACC-514E are internal option-modems, which are applied to the SD-170E series to increase capability

for data applications. The goal of an internal modem is to improve the efficiency for data transmission and provide

maximum flexibility for user applications. The most obvious method of increasing the data efficiency is to maximize the data

signaling speed in the limited channel bandwidth. But, FSK, called direct FM modulation, has a very wide transmission

bandwidth requirement. To solve this problem a GMSK (Gaussian Filtered Minimum Shift Keying) internal option-board can

be used. Generally data has a wider bandwidth than audio. So, direct application of data is not matched with an audio

system and its application. For instance, if sub-audio (Tone) SQ system applied to a data application, its frequency conflicts

with that of sub-audio. Moreover, the inputted data is filtered by the audio filter circuit resulting in broken data transmission.

To overcome these problems and provide maximum flexibility, an FFSK (Fast Frequency Shift Keying) internal option-board

can be used.

COMMUNICATION BETWEEN DTE AND OPTION-BOARD

Our internal modem options consist of Slave MCU, Modem IC, and extra circuitry. These option-boards directly

communicate with DTE (Data Terminal Equipment) to send and receive meaningful data through the DB-15 connector on

the digital board of the SD-170E. These modems are designed to accept RS232 serial data format and are also capable of

high speed wireless data-transmission between two or more devices. More detailed information for the modem option

boards is given in the technical manual for the ACC-513E/514E. Your dealer will help you define a TX On/Off delay time,

RX On delay time, Baud Rate, Modem Enabled, Modem Baud Rate, Data flow control, and Test Mode.

Transmission GPS Data through Modem

The SD-170E supports GPS data handling. That may help your implementation for a system related to GPS. If it is not

enough for your application, received position data from the GPS module placed in an SD-170E can be reprocessed by

your own application. The ACC-515E is a GPS module for the SD-170E, which releases 11 different output data according

to the NMEA-0183 format, which can be selected by you, the available data should be processed by your application.

Received data from the ACC-515E will be released via the DB-15 connector of the SD-170E and/or transmitted to another

system through an installed modem. More detailed information for the GPS option board is given in the technical manual for

the ACC-515E.
