    Not getting serial control of radios attached to IP-223


    What are some of the reasons for no serial control of radios attached to IP-223? 



    Serial control of some Kenwood, EF Johnson, Sepura and iDEN radio models require data initialization upon boot up of the IP-223 before the data connection becomes active. This is indicated by a message in the display of the IP-223, such as “KENWOOD” for Kenwood radios and “EFJOHNSON” for EF Johnson radios (The radio must be powered up before the IP-223 is power cycled.)

    If you do not get this confirmation upon boot up, you will need to do some troubleshooting. This indication will persist in the IP-223 display until the first time the radio is keyed up. If you are not getting any indication of serial data initialization, check to see that the serial cabling is correct and that the serial programming jumper is inthe correct position for the radio installed.

    If you are using Line 2 of the IP-223, be aware that a Serial Y cable is required to adapt the standard Telex radio to IP-223 interface cable for use with Line 2. Check to see that you have selected the correct serial data mode in the IP-223 Per Line Settings page, for the radio model you are using.
