Hi All,

I want to upgrade to the NX586 programming module from the phone modem feed with the DL900 software but would like to build a clone of the NX586 rather than purchase one due to the cost etc.

I know the input is RS232 at 9600 baud and I assume the output is 9600 baud to the Keypad data input but what levels and is there a coding format change inside the module. I can find very little details on the module apart from the user notes.

Anybody have a circuit or technical data on the unit and are there circuits around for the NX-8 v2 board ?

thanks for any assistance,

OldOne.
