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.
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.

User should send Channel Change Command ( 0x64,0x02 , ( 0x64 + 0x2 ) ) to Radio. If Byte2 and sum of Byte0 and Byte1 among received data are same, Radio sends ACK data to user and changes to 2nd channel. If not, Radio would send Nack data. Audible alert tones Your SD-170E series data radio has a sophisticated microprocessor control which provides a range of audible tone.

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.
