I'm trying to set up channel steering for a Motorola CDM1250 and have the radio working without a URI. If I ground the channel pins the channels change on the radio fine. Now when I connect the pins to a URI-x gpio1 gpio2 gpio5 and gpio6 It dosent seem to work. I have gpio1=out0 , gpio2=out0, gpio5=out0, gpio6=out0 and when I do a *584=cop,61,GPIO5=1 or *585=cop,61,GPIO5=0 nothing seems to change on the URI, either state I see +5v on the URI. Should it not get pulled to ground?
Am I doing something wrong?
Thanks & 73 de Scott KB2EAR
