Wiring the Digital Inputs
The EDS-510A has two sets of digital inputs, DI 1 and DI 2. Each DI
consists of two contacts of the 6-pin terminal block connector on the
EDS-510A’s top panel, which are used for the two 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
┴
/I1 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 EDS-510A’s top
panel.
Communication Connections
Each EDS-510A switch has 3 types of communication port:
•
1 RJ45 console port (RS-232 interface)
•
7 10/100BaseTX Ethernet ports
•
3 gigabit Ethernet ports:
3 10/100/1000BaseTX ports, or 1 10/100/1000BaseTX and 2
1000BaseSFP (mini-GBIC) ports, or 3 1000BaseSFP (mini-GBIC)
ports
In this section, we present two types of diagrams—Pinout Diagrams and
Cable Wiring Diagrams—that convey information about the ports and the
cables used to connect the EDS-510A to other devices:
Pinouts
—
The “Pinouts” diagrams display the type of signal passing
through each of the port’s pins.
Cable Wiring
—
The “Cable Wiring” diagrams present standard cable
wiring schemes for cables used to connect the EDS-510A’s ports to other
devices. These diagrams display three pieces of information:
1.
When building your own cable, refer to the
“pin-to-pin”
cable
wiring information displayed between the two vertical dashed lines
to see which pin of the connector on the left should be connected to
which pin of the connector on the right.
2.
The information to the left of the left vertical dashed lines gives the
pinouts of the relevant EDS-510A port.
3.
The information to the right of the right vertical dashed line gives the
pinouts of the opposing device’s port.
NOTE
1.
The pin numbers for male DB9 connectors and hole
numbers for female DB9 connectors are labeled on the
connector.
2.
The pin numbers for 10-pin RJ45 connectors (and ports) are
typically not labeled on the connector (or port). Refer to the
following Pinout and Cable Wiring diagrams to see how
10-pin RJ45 pins are numbered.
