Vern, Not sure about the purple wire you are looking at from the Mastr II.
The RC-1000V can be configured for either active high or low COS/CAS. This is selected with jumper JP1, but for Mastr II no jumper needed. A low is .5 V or less and a high is 2-30 V. The Mastr II will put out about 10 volts on its CAS with squelch open. Really sounds as if you are not getting to CAS in the Mastr II. This is on its squelch board. Might look in FILES of this board for info. There is lots of info here. 73, ron, n9ee/r >From: mung_bungholio <[EMAIL PROTECTED]> >Date: 2007/07/10 Tue PM 05:49:16 CDT >To: [email protected] >Subject: [Repeater-Builder] Re: GE MASTR II and RC-1000V > >I don't know if my other post made it through or not since I sent it >from my email but anyway. > >I put the meter on the CAS line the purple wire from the MASTR II and >I do get a change in voltage but it only goes to about .5 v instead >of the 10v that the RC-1000 is looking for to key the repeater. > >Is the CAS voltage dependant on signal or is it either high or low? >If it isn't dependant on signal then I need to figure out why I am >not getting full voltage to that line.
