G2012TR repeater transmitter

The coverage of service pager transmitter G2012TR can up to 3-4km (diameter) with the signal booster. If you want to build a wireless communication region within this rang, look no further.
The frequency of this service pager transmitter is 402-470Mhz. Using our paging software or yours (as it is a flexibility system) , you can send the text message to the alphanumrec pager or watch pager simply.
Sometimes, the region such as hospital, mall, construction site have building, tree to block the signal. Just connect the transmitter with power adapter and fix it in a suitable place. Then it work as a signal booster. It is so simple to booster the range of communication.

Receive data format of transmitter:

0x19——–>Start of message

1byte ——>’R’

7 bytes —->capcode ( ascii format ‘0’–>0x30,’1′—>0x31 )

1 byte —->control bit ( bit 7—-> 1

bit 6—-> 1—->Still sending head code after message,0—>Close this function

bit 5,4–> 00–>A TONE,01–>B TONE,10–>C TONE,11–>D TONE,

bit 3—-> 0—->numeric message,1—->Alpha message

bit 2,1–> POCSAG baud 00->512,01—>1200,10–>2400

bit 0—-> Polarity 0—>normal, 1—>reverse


N Bytes —->Content of message , not more than 300 characters,8bit ascii.

0X18——–>Message end



When a message succeed, the transmitter will reply 0x19,”RXOK”,0X18 to PC


Using capcode 1234567,normal,1200BPS,A call send “ABCDEFGH” Send by serial port of PC: 0x19,”R1234567″,0X8A,”ABCDEFGH”,0X18 HEX DATA: 19 52 31 32 33 34 35 36 37 3F 41 42 43 44 45 46 18
