Installation / Preparation for commissioning
6.3 F/B input (optional)
The measuring system is equipped with a device-specific V/R input on the device
connector. By connecting the external V/R input with supply voltage (US), the currently
set counting direction is inverted. This also changes the sign of the measuring system
speed.
6.4 Cable definition
Cables should be twisted in pairs and shielded. The maximum cable length and the
cable cross-section depend on the SSI clock frequency and the cable properties and
should be adapted to the conditions.
6.5 Connection – notes
Mainly, the electrical characteristics are defined by the variable connection technique.
Whether the measuring system supports

is therefore defined by the device specific pin assignment.
The connection can be made only in connection with the device specific pin
assignment!
At the delivery of the measuring system one device specific pin assignment in printed
form is enclosed and it can be downloaded afterwards from the page
„www.tr-electronic.com/service/downloads/pin-assignments.html". The number of the
pin assignment is noted on the nameplate of the measuring system.
