10.6 iTNC Serial Data Interfaces
10.6.1 General information
10.6.2 RS-232-C/V.24 interface
Hardware
July 2013
The iTNC features an interface of the following type:
RS-232-C/V.24
Three transmission protocols are available:
Standard communications protocol
Transmission protocol with Block Check Character (BCC)
LSV2 transmission protocol
Note
No connection to the serial interface of the iTNC can be established if the
file manager on the iTNC is open.
RS-232-C/V.24 is the designation for a serial interface. Data transfer is
executed asynchronously, with a start bit before each character and one or
two stop bits after each character.
Transmission distance: up to 20 m
The physical connection between two RS-232-C/V.24 interfaces is an
asymmetrical line, i.e. the common ground connection between transmitter
and receiver is used as a return wire.
