10.6 iTNC Serial Data Interfaces
10.6.1 General information
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
10.6.2 RS-232-C/V.24 interface
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
Hardware 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.
Physical connections:
Note
No connection to the serial interface of the iTNC can be established if the
file manager on the iTNC is open.
