Wiring the Digital Inputs
The EtherDevice Router has one set of digital input, DI. The DI consists of
two left contacts of the 4-pin terminal block connector on the EtherDevice
Router’s top panel, which are used for the DC inputs. The top and front
views of one of the terminal block connectors are shown here.
STEP 1: Insert the negative (ground)/positive
DI wires into the
┴/I terminals, respectively.
STEP 2: To keep the DI wires from pulling loose,
use a small flat
-
blade screwdriver to tighten the
wire
-clamp screws on the front of the terminal
block connector.
STEP 3:
Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on
the EDR-
G903’s top
panel.
Communication Connections
Each EtherDevice Router has 2 types of communication port:
1. 1 RJ45 console port (RS-232 interface)
2. 3 combination 10/100/1000T(X)/1000BaseSFP ports (EDR-G903)
3. 1 combination 10/100/1000T(X)/1000BaseSFP port and 1
10/100/1000T(X) Ethernet port (EDR-G902)
RS-232 Connection
The EtherDevice Router has one RS-232 (10-pin RJ45) console port,
located on the top panel. Use either an RJ45-to-DB9 (see the cable
following wiring diagrams) to connect the EtherDevice Router’s console
port to your PC’s COM port. You may then use a console terminal program,
such as Moxa PComm Terminal Emulator, to access the EtherDevice
Router’s console configuration utility.
