Have been able to complete up to step 12 of System Setup however cannot get Icom 706 to power on via the RRC-1258 MK2 boxes. The settings file of each of the two boxes is attached. If the control cables are connected via the cat5 cable joiner adapter, the radio will power up via the control head but not when separated by the RRC boxes. I think the IP addresses are within the range acceptable by my network but cannot see any other setting that may be preventing the rig from powering up. Following reset of the boxes, the yellow LED on the AUX enet connector is off but within about a minute of trying to power up the radio, the yellow LED begins to blink but nothing else happens. Have tried using a SIP password and no password with no effect. Can you suggest any other tests or settings to try?
