Mainly used in security monitoring in the field, as a wireless PTZ command control systems, transmission distance can be up to 5km or more. In general, a monitoring system which requires only a single front-end can control all of the cameras. Interface is a standard RS485 cable, terminal access method and the commonly used method of cable access, as only three conditions can be achieved to meet the front and back-end communication:
Transfer rate: 1200bps, 2400bps, 4800bps, 9600bps
Compatible voice or data signal transmission and transparent
Frequency range of 150MHz, 230MHz, 350MHz, 450MHz
Frequency can be set to 256, each frequency interval 25KHZ (standard)
Receive, send one, send digital and analog signals Jie Ke, switch quickly
Can send and receive frequency of air with frequency, but also different frequency
Double loop, double-VCO structure, high stability
Internal use of imported power amplifier module, 5W
Interface uses standard TTL, RS232 (or 485) level, you can directly control the keyboard or personal computer connected
SMT process, stainless steel shell, compact, easy to install, can add heat sinks
Built-TNC antenna interface directly with antennas
Indicators in line with national standards
Specifications in accordance with test methods used, "Mobile Communications" 90 "Standard"
1, to the same communication interface (RS485 or RS232 interface)
2, to the same baud rate (1200bps, 2400bps, 4800bps, 9600bps)
3, to the same parity bit (odd parity, even parity, no check)
