No setting is available for the short range galvanic modem on the HMI. There are how-
ever some settings that can be made on the DIP-switch located behind the cover around
the line connector at the back of the terminal as shown in
figure 37
. After the connector
has been disconnected, if attached, the cover plate can be removed by pulling the middle
of the cover plate. No settings are located on the circuit board.

Only switch 1 and 2 are used on the DIP-switch. The function is dependant on the set-
ting of the timing signal, see
table 38
. In normal operation switch 1 is set in ON position
at one end of the communication channel and switch 2 is set ON at the other end. The
rest of the switches are set to OFF.

There are also LEDs for the supervision of the communication channel that can be seen
when the cover around the fibre optic connectors is removed. These LED’s are found
below the DIP-switch. The function of the LED’s is explained in
table 39
.
