    Wireless specifications

    ItemSpecifications
    Wave typeDirect sequence spread spectrum (DS-SS)
    Transmission distanceApprox. 250 m outdoors (straight, obstacle-free distance), Approx. 50 m indoors
    (Note) The main unit, standard antenna and antenna with cable are designed for indoor use. If they are used outdoors, then take water-proof measures such as using plastic cases, etc.
    Wave output6 mW / MHz or less
    Frequency2403.328 MHz to 2480.128 MHz
    Number of channels76 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.
    Number of channels in same transmission area15 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.
    Transmission speed134kbps
    Communication style1: N topology (N: 99 units max.)
    Repeater function8 repeaters (Between master and slave)
    Response timeOFF to ON, ON to OFF: Max. 80 ms
    (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.

    Serial communication specifications

    ItemSpecifications
    InterfaceConforming to RS232C
