Ethernet Connector
The
Serial Server
has a standard RJ-45 receptacle mounted in the top
edge of the chassis. The
Serial Server
can be connected to an Ethernet
hub, switch, or wall plate using a standard straight-through RJ-45
(male) Ethernet cable. To connect directly to an RJ45 Ethernet port on
a PC or laptop a crossover Ethernet cable must be used.

Power Connector
Plug the ultra-miniature phone plug from the included power supply
into the power jack and then plug the supply in. When power is applied
the Red power light will illuminate. The tip of the power plug is
positive; the sleeve is negative.
Reset Button
This switch resets the unit, similar to the effect of removing/applying
power. The Reset switch is recessed to avoid accidental operation. To
reset the unit, insert a small plastic tool, press lightly and hold for three
seconds. The Link and Ready lights will go out and then come back on.
