Accessories The following accessories can be helpful; they are available in specialized computer stores:
D-sub adapter connector 25-pin
"Opto Bridge"
Metallically isolates the serial interface by means of
integrated opto couplers and thus protects from:
- Overvoltages
- Different load potentials by different main
current circuits
- Interference voltages on ground lines
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!
