76 ch (Select with communication channel switch)
(Note) Adding to the fixed channel, 76 ch (00 to 4B), 89 group channel can be selected. Group channel is the function that it selects connectable channel from several fixed channels automatically. When using repeater function, use with the fixed channel. When using group channel, settable channel numbers are decreased in the same communication area and the communication time becomes longer.
15 channels recommended (when select fixed channel)
(Note) It is different according to the mounting conditions, when several channels are used in the same communication area, communication error might occur due to interference radio wave.

(Note) There are no error without serial communication at 1: 1 topology. Response time: Time from input signal to input terminal to output from output terminal in connected equipment. When input signal is shorter than response time, there is a possibility not to transfer to output side.
Conforming to RS232C
Half-duplex
Synchronous communication method
Stop bit: 1 bit
Parity: Not available / Available (odd / even)
