Here is how I have my CAT-300 connected via the 15-pin accessory plug:
1 Hook Switch Must be grounded for unit to transmit 2 TX Mod. input ground 3 Direct Modulation Input This is where your CTCSS and/or DCS output from your controller would go. (SUB TONE) 4 RX Discriminator output This is the raw receiver carrier, this is before squelch 5 TX Modulation input Transmit audio out of the controller 6 Speaker ground 7 Switched B+ 8 PTT 9 Speaker Input This ties to pin 12 to use internal speaker 10 De-Emphasis output Squelched RX audio DO NOT USE 11 GROUND 12 Speaker output RX audio controlled by volume control 13 COR output I believe this is an active low 14 NC 15 NC ALSO: Remove/Disconnect the internal signaling unit. On CN6 of the repeater (or CN2 of the controller end of the cable) apply a jumper to pins 2&3, 8&9, 10&11. If the external controller is wired CORRECTLY to the 15 pin accessory plug, it WILL work properly. NEVER use the internal controller with an external controller. You are asking for problems. 73 de Mark - N9WYS -----Original Message----- From: Repeater-Builder@yahoogroups.com On Behalf Of Mike Morris WA6ILQ At 08:41 PM 04/23/08, you wrote: >--- In Repeater-Builder@yahoogroups.com, "n9wys" <[EMAIL PROTECTED]> wrote: > > > > Give me a couple of days to dig up my notes, Frank...
