Wiring the Digital Inputs
EDS-726 has two sets of digital input—DI 1 and DI 2.
Each DI comprises two
contacts of the 6-pin terminal block connector on EDS’s top panel. The
terminal block is also used for EDS’s two DC inputs. 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
┴
/I1 terminals.
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 EDS-726’s top panel.
Communication Connections
The pinout and cable wiring diagrams in this section show how the ports on
EDS-726 connect to other devices:
Pinouts
are diagrams that indicate the type of signal passing through each of
the port’s pins.
NOTE
1.
The pin numbers for male DB9 and DB25 connectors, and hole
numbers for female DB9 and DB25 connectors are labeled
on the
connector
. However, the numbers are typically quite small, so you
may need to use a magnifying glass to see the numbers clearly.
2.
The pin numbers for both 8-pin and 10-pin RJ45 connectors (and
ports) are typically
not
labeled on the connector (or port). Refer to
the Pinout diagram below to see how RJ45 pins are numbered.
RS-232 Connection
EDS-726 has one RS-232 (10-pin RJ45) console port, located on the side panel.
Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect Moxa
EDS-726’s console port to your PC’s COM port. You may then use a console
terminal program, such as Moxa PComm Terminal Emulator or Hyper
Terminal, to access Moxa EDS-726’s console configuration utility.
