3.4.4 PR 5510/04 Serial I/O
The plug-in card has two channels (1x RS-232 and 1x RS-422/485), which can be used
simultaneously and to a great extent independently. The RS-422/485 interface is electrically
isolated. Up to 2 PR 5510/04 cards (Slot 1 and 2) can be plugged in. The relevant interface
parameters can be configured under -[Serial ports parameter]; the DIL switch S101 must be set
for RS-422/485 additionally.
Internal connection:
34-contact socket terminal strip
Number of channels: 1x RS-232, 1x RS-422/485

PR 5510/04 RS-232
The RS-232 interface is independent of the S101 switch settings.
It can be used only for point-to-point connection.
PR 5510/04 is provided as an equivalent to the [Builtin RS-232] interface in the RS-232 channel with
additional signals: DCD, DTR, RI.
The built-in and PR 5510/04 interfaces comply with the standard pin allocation; i.e., they are
equivalent in the following connecting diagrams. Thus only the RS-232 connections for the built-in
interface are described in this manual (see Chapter 3.3.2).
