Long Range Wireless RS485 Data Transmitter 

 

Product Model: SG-F408

Application: 
Generally, there are three important points must be emphasized:

1 The communication interfaces are the same standard RS485 / RS232 interface;

2 The same baud rate at 2400bps;

3 Terminal access method and the commonly used method of cable access must be in the same parity bit.

 

Special Features:

1

Transfer rate: 2400bps, compatible voice or data signal transmission

2

Can be set 256 Spots, the channel spacing is 25KHZ (standard)

3

Integration of transceiver, both digital and analog signals can be send and switch quickly

4

Either co-frequency or unco-frequency in air transmission

5

Double loop and VCO structure, high stability

6

Use 20W imported power amplifier module

7

Use standard TTL, RS232 (or 485) level, convenient to connect to the control keyboard or personal computer directly

8

SMT design, stainless steel outshell, miniature size and easy to install, can stick heat sinks

9

Testing methods is in accordance with Mobile Communications “90” standard
