DEWE2-PA7 • Technical Reference Manual • Printing version 1.0.1 • February 15, 2018
MAIN SYSTEM
11 Up- / Downstream interface PCIe x1
The DEWE2-PA7 is equipped with a PCI express x1 interface by default. In combination with the TRION™-SYNC-BUS
(19)
it allows easy high-speed channel expansion with F-series chassis.
Note: The PCIe 1X interface connector to connect a DEWE2-F series, is no longer scope of supply for newer models
of the DEWE2-PA7. Please note that the TRION-SYNC-BUS interfaces are not affected by this change. To add
an expansion to a DEWE2-PA7 use a TRIONet via the TRION-SYNC-BUS interface.
12 PS/2 interface connector (mouse)
To connect an external PS/2 mouse to the system. The connector meets standard pin assignment.
13 PS/2 interface connector (keyboard)
To connect a keyboard to the system. The connector meets standard pin assignment.
14 Display port connectors
Additional to the DVI connector interface the DEWE2-PA7 supports two Display port connectors with standard pin
assignment.
15 DVI connector
The DVI connector meets standard DVI pin assignment.
16 RS-232 interface connectors (COM1 & COM2)
The RS-232 interface connectors (male) are located on the left side of the DEWE2-A4L. They are configured as
standard RS-232 interface COM 1 & COM 2 and can be used for mouse or other peripheral units.

Schematic
17 GBit ethernet LAN connector
The DEWE2-M7 supports 10/100/1000 BaseT Ethernet with standard RJ45 connector.
18 Audio I/O interface
Mic, Headphone & Line Out.
19 TRION™-SYNC-BUS
The TRION™-SYNC-BUS in combination with the downstream interface connector
(11)
allows easy high-speed channel
expansion with F-series chassis (e.g. DEWE2-F4s, F7...).
Sync cable has to be ordered separately:
DW2-CBL-SYNC-01:
Sync cable with RJ45 plugs, 1 m.
DW2-CBL-SYNC-03:
Sync cable with RJ45 plugs, 3 m.
Note: The PCIe 1X interface connector to connect a DEWE2-F series, is no longer scope of supply for newer
models of the DEWE2-PA7. To add an expansion to a DEWE2-PA7 use a TRIONet via the TRION-
SYNC-BUS interface.
