ALERT!If you use an ethernet box to switch between a SignalinkUSB box and another modem, you may be in for some surprises.The Tigertronics SignalinkUSB cable SLCABK3 brings out 6 of the wires to the RJ45 connector. EACH of the Line In, Line Out, and PTT output have their own SEPARATE grounds for the sleeves of the connectors.Internally, the SignalinkUSB box joins them up to work well. HOWEVER, the K3 Line In, and Line Out jacks are not sleeve grounded to the chassis, and are set up as balanced Input and Output.If you wire up a modem, such as the SCS PTC series or other, make sure that you wire the 3 grounds out to the corresponding pins of the RJ45 connector or you won't have it work right.Use your Ohmmeter to verify that each of the SCCABK3 sleeves are grounded to the modem through the switch.Neglecting that could have you spinning your wheels for a long time.Mike VE3EQP/W4 .....> ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
