Connecting the Hardware
This section describes how to connect the DA-661/662/663 to serial devices. The topics covered in
this section are: Wiring Requirements, Connecting the Power, Connecting to the Network,
Connecting to a Serial Device, and Connecting to the Console Port.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your DA-661/662/663.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
Temperature Caution!
Be careful when handling the DA-661/662/663. When plugged in, the DA-661/662/663’s
internal components generate heat, and consequently the outer casing may feel hot to the touch.
You should observe the following common wiring rules:
yUse separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire
conduit. To avoid interference, wires with different signal characteristics should be routed
separately.
yYou can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can
be bundled together.
yKeep input wiring and output wiring separate.
yWhere necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
To power on the DA-661/662/663, use the power cord comes with the product to connect the
power line to the DA-661/662/663’s AC power connector. The power connector is located on the
right side of the rear panel. Next, turn on the power switch. The DA-661/662/663 takes about 30
seconds to boot up. Once the device is ready, the Ready LED on the front panel will light up, and
the DA-661/662/663 model name and firmware version will appear on the LCD screen.
