HEIDENHAIN iTNC 530 HSCI Service Manual

14 – 192 HEIDENHAIN Service Manual iTNC 530 HSCI
14.2.2 Via RS-232-C/V.24 serial interface
Requirements  A laptop/PC with an RS -232-C interface or a USB interface (for connection of a USB/RS -232-C
adapter)
 A transposed serial data transfer cable ("null-modem cable") for the connection of laptop and
D-sub connector on the electrical cabinet or on the console (HEIDENHAIN adapter block).
Possible configurations, also for direct connection of the laptop to the iTNC 530 HSCI
--> See ”Cable overview” on page 14 – 209.
 An opto bridge"
Connection setup
8 Connect your laptop to the RS-232-C adapter connector on the electrical cabinet or on the console
with a transposed serial data transfer cable (and possibly an opto bridge).
8 Now configure the serial interface on the iTNC 530 HSCI.
Configuring the
serial interface
on the iTNC
8 Call --> See ”Operating modes of the data interfaces” on page 14 – 213
8 Select a baud rate for the LSV/2 protocol.
You can select the highest possible baud rate. Should there be any transmission problems, you can
revert to lower baud rates.
Note
Do not use self-made cables (shielding problems, contact problems, short circuits, etc.).
Mark your cable as "transposed" or "non-transposed"!
Attention
HEIDENHAIN recommends using an "Opto Bridge".
This serial adapter connector ensures metallic isolation via optocouplers and can thus protect
the serial interface against overvoltage, different load potentials and interference voltages on
the ground lines.
"Opto bridges" are available in specialized computer stores.
Please note:
If the machine manufacturer has already mounted an opto bridge, a further opto bridge will
not function, as such components must be powered from both sides!
Note
Usually, the machine tool builder mounts the HEIDENHAIN adapter connector for RS-232-C to one
of the walls of the electrical cabinet or in the console.
If this is not the case, note that mostly you must use a different data transfer cable for direct
connection of the iTNC 530 HSCI . --> See ”Cable overview” on page 14 – 209.
Note
The iTNC 530 HSCI automatically recognizes when the LSV-2 protocol is used (e.g., data transfer
with TNCremoNT).
No setting is required in the line Operating mode.
