8-2 Set-Up interfaces (SynTop, DOLFI)
RS485 link
SynTop can communicate with several PPCs using an RS485 link.
Up to 20 PPCs can be connected (driver rating of the RS485 driver of the
PPC). If there are more PPCs operated in one RS485 link, then RS485
repeater have to be installed at suitable positions.

Fig. 8-3:
RS485 link of SynTop to several PPCs
This necessitates couplers from RS485 to RS232 for the connection of
the PC to the RS485 link.
An example are the coupler interface modules PSM-EG-RS232/RS485P/2D or PSM-ME-RS232/RS485-P made by Phoenix Contact.
Interface module PSM-ME-RS232/RS485-P
Fig. 8-4:
Interface module PSM-ME-RS232/RS485-P
Switch settings:
1. 180R Bus-End ON (only at the bus end)
2. Dip switch 1 and 3 ON for baudrate 19,2; rest OFF
3. RS232 Device type at DTE
With switch 180R BUS-END a matching resistor 180R and each 470R
against +5V and GND can be connected to the bus end.
The voltage supply for the interface modules comes from 24 V which is
connected via the intended screw-in clamps.
