What panel and version do you have.
Press menu 4 on the keypad in day mode it will tell you exactly what you have.
The user code, and id is exactly that.
ie Master user has id 1, and so on, the code is the code the user would type in the keypad to set/ unset the alarm, if you set the users up you should be able to see which user id to use.
The version is relevant to what you may need to do for the system, the user and id are only for the smart key side of things and shouldnt affect the keypad part of the app.
Older panels had to change the I/F mode of the com-ip to CC and program the com port as not used, this will let the app work and wintex, but wont be able to send alarm communications. 2.09 panels should be able to use as is with no changes to the com-ip mode mode and the comport programmed as Com-ip.
Have you double checked your user settings are completed, ie udl, port number etc
