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.

Note:

Refer to Appendix D for details on Network Cables

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.
