FWIW, I have probably 100+ C40s in the wild all running via serial and have never had a problem with them locking up -- might be worth making sure the C40 is running relatively recent-ish firmware.

Two other questions - Which version of the C40 module are you using? - Does the Codec have authentication for serial connections (I forget the exact title but it's somewhere in the menu) disabled (default is enabled). If authentication is required for serial connections you need to "log in" to the serial port & I'm wondering if the codec is "timing out" the serial login and that may cause the perceived lockup Lincoln -----Original Message-----

Subject: [Crestron] Re: Cisco C40 via SSH I originally programed the system with 232 control for the C40. It would work for half a day or so and then lock up. Crestron would then start reporting buffer overflows from the 232 module. A processor reboot would restore operation until the next lock up. At that point I changed it to IP control and everything has been running fine for four months. Now the IT folks want a tighter network and changed the Codec to SSH. This leaves me in my current predicament. SSH is not capable at this time and the 232 module blows up after half a day. Mark --- In Crestron@..., Lincoln King-Cliby <lincoln@...> wrote:
