The Digitax F3 Plus Taximeter has several communication channels that make possible the communication with the external world.
Two independent RS232 serial ports at baud rate from 300 to 115200 and a 4 wire synchro channel plus a special printer driver, allow the interfacing to several devices at the same time.
The Commtax 2 included protocol allows remote managing of all the taximeter, magnetic Credit Card reader , chip card and printer functions.
The link to a dispatch system or another mobile terminal is accomplished on the RS232 port at any baud rate from 300 to 115200 using a frame structure N, 8, 1: signal level +/- 12 V, using the protocol COMMTAX 2 described in this document.
