RS-422 / RS-485
An RS-422 / RS-485 port allows point-to-point communications with
a single device. Through the RS-485 port, the AdaptaScan Reader
can also communicate with a DH-485 network. Both master and
slave modes are supported. As a master device, the Reader sends
data directly to an SLC 5/03 or 5/04 processor’s data table; no
polling is required by the SLC. As a slave device, the Reader
connects to the Flexible Interface Module (Catalog No. 2760-RB) for
multi-drop communications.
