Fuse1：100 mA
Fuse2：750 mA
Fuse3：6 A
1.5.5 Group connection
1. Every controller must be have its own identified number to support software recognition. Go to System /
Misc. page, and change its id number.
2. Group wiring：
The MTR-1 terminal pin 1 and pin 4 are the power supplied ports, so just one MTR-1 needs to be
connected with pin 1,2,3,4, and others connect with pin 2, 3 only.

Figure 8 – Group connection diagram
Note: It is strong suggestion that using another power source to power the communication card (MTR-1), If
the wire length over 25 meters. This prevents the MTR-1 go in an unpredictable condition by voltage drop.
2 Communication protocol for user monitoring (start)
2.1 Communication Interface
2.1.1 Connect with GTR82 via RS-485 interface
Connection method1
Master device (RS-485) ÙGTR85 as slave device (RS485)
Master device UART configuration
9600 bps, no parity, 9 data bits, 1 stop bits
The leading 8 bits information defines as “Address”, when the 9th bit sets to 1 (or logic high), and it defines as
“Data” when the 9th bit sets to 0 (or logic low).
Information transmitting format
The master device transmitting information form includes three parts that are Address, Command as well as
Data in three bytes.
Address represents the GTR85’s identified number.
Command represents with function group that master device invoke to be executed.
Data represents which exactly command that master device invoke to be executed.
Encryption processing
Each byte of the transmitting information must be encrypted as follow; let’s say FID, the factory ID number, is
7

0x6F.
Data processing Example
Address = Address XOR FID Address = 0x41 XOR 0x6F = 0x2E
Command = Command XOR FID Command = 0xC8 XOR 0x6F = 0xA7
Data = Data XOR FID Data = 0x05 XOR 0x6F = 0x6A
For example, the master device transmits information to GTR85 controller via RS485 should be 0x2E then
0xA7 and then 0x6A as sequence.
Information receiving format
The master device receiving information form includes two parts Echo and Check.
Echo represents the information that GTR85 responds to the master device transmitting information.
Check is used for master device checks the accuracy of the receiving information.
Receiving information processing
Data processing Example
Echo = Echo XOR FID Echo = 0x6F XOR 0x6F = 0x00
Check = Check XOR FID Check = 0x91 XOR 0x6F = 0xFE
The master device receives information from GTR85 controller via RS485 should be 0x00 and then 0xFE.
2.1.2 Transmit information via MTR-1
Connection method 2
Master device (RS-232) ÙMTR-1 as interface (RS232 ÅÆ RS-485) ÙGTR85 controller as slave device
(RS485)
Device port configuration
19200 bps, no parity, 8 data bits, 2 stop bits
Information transmitting format
The master device transmitting information form includes four parts that are Start, Address, Command as
well as Data in seven bytes.
Transmitted information
Format Start Address Command Function
Example | 4 1 C 8 0 5
The start byte, ‘|’ (0x7C in hexadecimal form), is the synchronous character of the MTR-1. The description of
Address, Command and Data are the same as defined in section 2.1.1.
All transmitting information should be transfer from hexadecimal to twoASCII characters, for example, if the
Address is 0x41, then the transmitting data is ‘4’ ‘1’, or 0x34 0x31 in hexadecimal form.
Encryption process
Data processing Example Split into two ASCII characters
Address = Address XOR FID Address = 0x41 XOR 0x6F = 0x2E 2E
Command = Command XOR FID Command = 0xC8 XOR 0x6F = 0xA7 A7
Data = Data XOR FID Data = 0x05 XOR 0x6F = 0x6A 6A
The master device transmits information to GTR85 controller via MTR-1 interface should be ‘|’ ‘2’ ‘E’ ‘A’ ‘7’ ‘6’
‘A’ in character way, or 0x7C 0x32 0x69 0x65 0x67 0x66 0x65 in binary way.
Information receiving format
The format of receiving information form MTR-1 includes four bytes, and is combined with Echo and Check
two parts. The descriptions of Echo and Check are the same as defined in section 2.1.1.
