Accessories The following accessories can be helpful; they are available in specialized computer stores:
D-sub adapter connector, 25-pin
"OptoBridge"
Metallically isolates the serial interface by means of integrated
optocouplers and thus protects from:
- Overvoltages
- Different load potentials due to different supply 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!
