Service manual AlphaCom XL transceiver Rev. 1.4 10-08-2011
Blz. 40/74
Serial port configuration
The AlphaCom XL contains 3 onboard serial inputs for OEM applications, 2 serial ports are configured as
RS-232 and the 3
rd
is a RS-485 bus.
Settings Serial port 1
The first serial port can be used for a so-called transparent serial connection over IP. For this application 2
AlphaCom XL boards are needed (or 1 PSTN2IP ML and 1 AlphaCom XL).
Both devices communicate with each other via the hard-wired Ethernet connection using a secured
encrypted protocol. With this solution it is possible to exchange a local serial connection between 2 devices
to a connection with 2 devices that are placed far away from each other or even in separate premises.
The way this application works is stated in a separate document and can be obtained from the Alphatronics
helpdesk.
