July 2013 10.7 Configuration of Interfaces 1903
10.7.2 Selection of interfaces and operating modes
To disable or enable the RS-232-C/V.24 interface:
Select MP5000.
If the interface is enabled, you can select the following settings:
Call the MOD functions.
Choose the desired operating mode from the table.
MP5000 Disable data interfaces
Input: 0: No interface disabled
1: RS-232-C/V.24 interface disabled
2: Reserved
3: Reserved
Communication
between iTNCs
Set both iTNCs to LSV2 protocol. The control from which you start the data
transmission is the master.
The PLC provides you with access to the data interfaces (EXT3).
10.7.3 Configuration of interfaces
To configure data format and the type of handshake in the EXT1/EXT2/EXT3/
EXT4 operating modes (EXT3/EXT4 only for the PLC):
Select machine parameter MP5020.x.
Data bits With bit 0 you determine whether transmission is to be with seven or eight
data bits. Transmission with seven bits is normally used; for printer interfacing
eight bits are required.
Block Check
Character (BCC)
With bit 1 you can ensure that the BCC is not interpreted as a control
character.
On the iTNC, numbers less than $20 are defined as control characters. If
calculation of the BCC produces a number less than $20, then a blank space
is sent in addition immediately before <ETB>. The BCC will consequently
always be greater than $20 and cannot therefore be interpreted as a control
character.
For the following external devices Choose the

PC with HEIDENHAIN software TNCremo LSV2
Non-HEIDENHAIN devices such as printer, punch or PC
with other data transfer software
