RS485 Network
The TFT500 Omni Driver has an on board RS485 port. This can currently be used for multi-elevator based TFT
displays using a network of IND079 transcoders.
The RS485 network should be connected together in a “daisy chain” using unscreened twisted pair.
All units on the RS485 network should have a unique
network address
, which is selected via the on board Network
Address dipswitch on the TFT500 and IND079. The network address is linked to the least significant byte of the IP
address of a TFT500 by default (this can be changed in the DragonFly settings).
There needs to be one TFT500 on the RS485 network acting as an
RS485
master
. This master mode function can be
selected via a jumper next to the Network Address dipswitch.
Note: The RS485 wires are
polarised
so should be connected to each terminal block in the same orientation.
Note: All RS485 wiring needs to be
twisted pair
. If there are untwisted sections, the network will not work.
