The wires connecting terminals 1 & 2 from
the 1812 Access Plus to terminals 8 & 7
on the DoorKing RS-485 boards MUST be
twisted. We recommend that you use
Cat5e cable for all the RS-485 connec-
tions (See page 12 for wire size and run
distances table). Use one twisted pair to
connect these terminals (terminal 1
connects to terminal 8; terminal 2
connects to terminal 7) and then one wire
from another twisted pair to connect the
common terminal (terminal 3 from the
1812 Access Plus to terminal 6 on the
RS-485 board).
If wiring will be
outdoors or under-
ground, use Cat5e
Gel Filled (flooded)
UV Resistant Direct
Burial Cable.
Any RS-485 Keypad, Cardreader and
MicroPlus RF Receiver sequence
allowed. Maximum distance from end
to end is 4000 feet in a Daisy Chain
format as shown, see next page for
different RS-485 wiring configurations.
Do Not power RS-485 devices from the 1812.
RS-485 devices must be powered from their
own power source. Refer to the individual device
wiring instructions for connection information
and wiring guidelines for these products.
Setting the device address switches
are different for each RS-485 device.
Refer to the individual RS-485
instruction sheet to set the addresses
for these products and see the next
page for more information about
address restrictions.
