Option 1
Configuration with the desired protocol (S-Bus PGU
configuration)
Option 2
Assignment (SASI) in the user program (the port must not be
configured as S-Bus PGU port)
If a programming device is connected again instead of the
peripheral device during operation, the mode is automatically
switched over to PGU (pin 6 logic 1 (DSR), in PGU mode:
DSR PING = 1)
In order to be able to use the interface again for the
connection of a peripheral device, Port 0 must be reconfigured
with the SASI command

1) When communicating with terminals, check whether certain connections are to
be bridged or to be set by the command SOCL on 1 or 0. Generally the use of
handshake (RTS / CTS) is recommended (see also manual 26/795, series PCD7.
D23x, graphics terminals).
Option 3
Port 0 can also be used as a modem interface with a 1 to 1 ca-
ble. As described in chapter 7.1.2 Hardware options, the check
box Full RS-232 handshaking on port 0 must be selected.
Option 4
With connection cable PCD8.K111, this interface can be used as
a programming device connection.
