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 30W 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 |
