QUICK START
GUIDE
Q. What are the factory presets?
A. “2-Wire” RS-485 half duplex operation; echo off,
bias in, termination out.
Switches 1, 2, 3, 4, 5 = ON
Switch 6 = OFF.
Switches 7, 8 = Not used.
Q. I want to use “4-Wire” RS-485, but the “4-Wire”
RS-485 devices do not respond with data.
A. When this unit is used to talk to a “4-Wire” device
that does not have biasing across the RS-485 receiver
lines, it may be necessary to set the Transmitter to RS-
422 Transmit mode: Switch 1 = OFF.
This setting can be used providing that the master is
on the opposite side of the repeater. No other 4-Wire
device can be connected to the transmit lines on the
side set for RS-422 transmit. The #485OPDRI has
switches to enable separate Transmit bias & Receive
bias.
Biasing
Bias is provided by 4.7kΩ pull-up/down resistors on
the Data In lines. This value is adequate for most
applications without termination.
