I am having some problems getting PTT action on a repeater I am converting from IRLP to Allstar. The DMK-URI is interfaced to the secondary port of a CAT-1000 controller. And the controllers second port is configured as active low. There is a 10k pull-up resistor on the CAT controller's COR#2 line. URI DMK-URI CAT-1000 CAT-1000 Pin 1 PTT Pin 5 COR #2 Pin 7 CTCSS DET Pin 9 PTT #2 Pin 8 COR DET Pin 20 GND Pin 17 GND Pin 21 MIC IN AC Pin 23 TX AUDIO #2 Pin 22 LEFT OUT Pin 12 Rx AUDIO #2 And I am using these settings: eeprom=0 hdwtype=0 rxboost=0 carrierfrom=usbinvert ctcssfrom=no txmixa=voice txmixb=no invertptt=0 duplex=1 plfilter=no deemphasis=no preemphasis=no rxaudiodelay=0 Running asterisk -r shows that its supposed to be playing the time (etc), but it never keys. Suggestions welcome. Thanks
