[App_rpt-users] DMK URI COS Level / Kenwood TKR-850

[Doug Crompton]

If it is positive true COS anything above +2 should assert COS -  in that case you would be using usb NOT usbinvert in your config.  COS is blocked by a diode so anything up to 20+ volts on a high is OK. It does have to go to a good low - 0V if possible.

Obviously if it is negative true COS it would be just the opposite and using usbinvert.

Go into the client - asterisk -rvvv  and watch the log. You should see a hungup status on drop of signal. You can exercise this manually for testing if desired.

Subject: [App_rpt-users] DMK URI COS Level / Kenwood TKR-850

 Is the 0-5 Volt COS swing on a Kenwood TKR-850 sufficient to switch the COS on a DMK URI? Can't seem to get my system to repeat. I'm out in the 'boondocks' with very few parts and a long way from a Radio Shack. Just hoping I don't need to buffer the COS somehow to get it to switch.
