Outline
The JRV-500B VHF TRANSCEIVER (after called JRV-500B) is shore basis
communication equipment for maritime communication system in 150MHz RR
band, is designed to satisfy the ITU radio regulation (RR). It attends the simplex
and duplex communications under operating conditions with 24H-hours
operation.
The desktop type or rack-mount type can be selected according to the
operating conditions. The full synthesizer controlled by a high performance
microprocessor has eliminated a crystal oscillator, which hitherto have been
needed for each channel.
The maritime mobile service radio communication channels are saved in
EEPROM. The operator can call up any desired channel on the spot.
Features:
1)
The JRV-500B can be operated 24-hours a day.
2)
Either desk top-type or rack-mount type can be selected.
3)
Direct channel mode and memory channel mode are provided.
4)
Up to specified eight channels can be saved in EEPROM.
(memory channel mode)
5)
The microprocessor allows easy operation.
6)
The external control is prepared for RS-422 and parallel ports.
7)
The DC power supply is automatically changed even if the AC power
supply fails. (AC power supply type)
8)
