Voyager door backup line
A door is managed using two Voyager devices (one on each side of the
door). During a network failure, to ensure the complete door functionality,
you can have a backup connection between the devices using the RS 485
serial line with encrypted protocol as shown in
Figure 27
.
The typical connection for the Voyager door backup line appears as shown
in
Figure 28
.
You can set the RS485 wiring length using the SW1 jumpers. For more
information on jumpers, see “Jumpers” on page 39.
