3 Basic Operations
3.1 Powering On/Off
When the repeater is turned off, press the power switch " " to power on the repeater. Then the
light "
present working mode. Press
3.2 Voice and Data Transfer
The receiving and transmitting frequency are different on the repeater. Repeater will turn the weak
receiving signal into strong transmitting signal and transmit on the same channel. When
transmitting, the light
flashes. The receiving and transmitting frequency and CDCSS/CTCSS can be set by CPS.
An analog channel or a smart analog/digital detecting channel can be programmed with one group
of CDCSS/CTCSS encoding and decoding list. When receiving CDCSS/CTCSS on the channel,
repeater will transmit according to preprogrammed CDCSS/CTCSS encoding and decoding list.
3.3 IP Connecting
Default IP address：192.168.1.100. Application update, parameters configuration and second

development can be made through this port.
3.4 Warning
When unusual situation happens, warning indicator light will be enlightened. For example, when
Receiving Frequency unlocks, the warning light will flash once one second; Transmitting
frequency unlocks, the warning light will flash once two seconds; When both transmitting and
receiving frequency unlock, the alarm indicator will stay light on. When the repeater occurs
unusual situation, please let the related professional to check and recover the repeater.
3.5 Programming Software
IP connecting status should be checked before programming. Make sure that the network button
in the tools bar is pressed down, (If the button is not pressed down, the IP address bar will be grey,
disabled), also need to make sure the connect button is pressed down (the default status of
connect and network buttons are pressed down), under the status of connect button pressed
down, the software will connect to the repeater by the IP in the address bar. While the connectivity
is successfully built, the status bar will show “Network is OK”, or the address bar will show
“Network XX”. If other programming software connects to the repeater, the late connect software
will show“Repeater is busy”, then the connect button will pop up automatically, and need to press
the connect button to re-connect.
3.5.1 File Menu

released.
Value Range: 0~7000ms, the step is 500ms, the default value is 4000ms.
Individual Call Hang Time: When a terminal radio initiates an individual call and no PTT presses,
repeater shall hang on for a period of time. During this time, the channel is being taken up, and
communication is regarded still going, no accept to other signal relay. If any presses PTT, then the
hang time recounts. Once the hang time is over, this communication is over too, channel will be
released.
Value Range: 0~7000ms, stepping is 500ms, the default value is 4000ms.
Emergency Call Hang Time: When a terminal radio initiates an emergency call and no PTT
presses, repeater shall hang on for a period of time. During this time, the channel is being taken
up, and communication is regarded still going, no accept to other signal relay. If any presses PTT,
then the hang time recounts. Once the hang time is over, this communication is over too, channel
will be released.
12
TR850 DMR Repeater Instruction Manual
Value Range：0~7000ms, stepping is 500ms, the default value is 4000ms.
Calling Hang Time: When a call ends, the repeater will hang on for a period of time, during this
time, when a terminal radio presses the PTT, no need to build connect again, just communicate
directly.
Value Range: 0~7000ms, the stepping is 500ms, the default value is 4000ms.
Network Setting: When networking, different repeaters can address to build a connecting by
setting the network parameters.
Local IP: The IP address of repeater, like 192.168.1.100.
Local Port: The repeaters use the UDP local port to connect to the server. The range of the port
is 0~65535.
Server IP: When networking, the IP of the server that repeater connects to.
Server Port: The repeater uses TCP server, TCP server connects needs a specific server port.
The range value of the port is from 0~65535.
Gateway IP：When networking, the gateway IP that repeaters interconnect to each other.
Transmit Frequency: To set the transmit frequency in the current channel. The range cannot
exceed what the repeater limits.
Receive Frequency: To set the receive frequency in the current channel. The range cannot
exceed what the repeater limits.
Power: To select current channel’s RF power level
Fan Control: User can set the Fan Work Threshold, Power Amplifier Protect Threshold and
13
TR850 DMR Repeater Instruction Manual
Standing Wave Ratio.

value, it stops working , the default threshold value is 80℃
Fan Work Threshold: As long as the temperature is higher the threshold value, the fan starts
working. The default threshold value is 45℃.
Fan Stop Work Threshold：As long as the temperature is higher the threshold value, the fan
stops working. The default threshold value is 35℃.
Standing Wave Ratio: It is used to shows if it’s the antenna match with the radio. The default
value is 3.0
Bandwidth: It’s used to select the channel spacing of the current channel. Options are, 12.5 kHz,
20 kHz, 25 kHz, the default option is 12.5 kHz.
Colour Code: It is used to select the colour code of the current channel. As long as the radios
with same colour code in the same frequency can communicate with each other.
Value Range: 0~15, default value is 1.
Squelch Type: It is used to select the receive mode of current channel.
Options: CSQ, CTCSS, CDCSS, -CDCSS.

Upgrade software: the main function is to download different function modules from PC to the
repeater, then set the main parameters on them.
Under the “Program” menu, find “Program Download”, then you can upgrade. But before
upgrading, you should select the path of the update package. If is a standard update package,
after select the path, each update file’s paths will be auto filled.
Upgrade Boot Loader
（1）Before upgrading, repeater should be power off, boot mode select 0101, select “Download
boot loader” and find the correct serial port between PC and repeater. If necessary, select the boot
loader file and uboot file.
（2）Press “Download” button, then a upgrade dialog box pops up, select “Yes”.
（3）When the control program shows “Wait for boot me……” the interface power on (Note: if the
16
TR850 DMR Repeater Instruction Manual
below interface flashes back, maybe fail to open the serial port. Please check the serial port
connectivity, or other program takes up the serial port.
（4）if the update is finished, software will note that. Please don’t forget to switch the boot mode
back to 1000.
Upgrading the System
（1）Boot mode should be 1000 while upgrading. Choose the system programs to be downloaded,
and remove unnecessary components according to needs. (For example: if the repeater could
work normally and connecting the PC network before upgrade, then you could remove the hook
behind the environment variable).
（2）Click “download” button to proceed. When upgrading, there is a progress bar to show the
upgrading status. And there will be a prompt message after the process is finished.
