1.
For a total cable length greater than 500’ (150 m), installing a 120
S
resistor on
terminals A&B of ports at the end of a loop
is required.
2.
Use the included network cable.
3.
Use a RS-485 network cable with the following characteristics: 2 twisted pairs
with shielding and AWG 24 or 28-caliber drain wire, with an impedance
of 120
S
.
EX: Belden 9842, 8132, 8132FO, 82842, 89842, West Penn Wire D4852,
D254852.
4.
For communication ports not at the end of a loop, maintain continuity of the
shielding by linking the drain wires.
5.
Ground the drainage wire of one control only. The other extremity of the drainage
wire must remain floating.
6.
The “RESET CONTROL” output is used to connect a “Controlled AC Outlet”
used to interrupt Internet access equipment power for 5 seconds when there is no
Internet communication for 20 minutes between the WebGate 3G and FarmQuest.
