Pin allocation of the fiber-optic connector

Using the fiber-optic connector (for fiber-optic transmission), the unit can be
read via 820nm optical fiber (glass).

Communication protocol:
The idle condition of the fiber-optic transmission line has to be configured
with the jumpers between the two connector elements:
•
Idle condition „Light off": the jumper must be placed on pins 1/2 (deliv-
ery condition)
•
Idle condition „Light on": the jumper must be placed on pins 2/3
The upper row of pins determines the condition of the receiver (RD), the
lower row of pins sets the condition for the transmitter (TD). Jumpers must
be placed in both rows!
