Using the Reset Switch to exit Console Mode
Press and hold the Reset switch for two seconds, or remove power from the
serial server, wait a few seconds, and turn the power on again. The LEDs go
back to their normal states when the device resumes normal operation.
Using the Reset Switch to Reload Factory Default Settings
Hold the Reset switch for more than ten seconds. The Serial LED illuminates
for the first two seconds; then the Ready LED illuminates. After 10 seconds,
both the Serial and Ready LEDs illuminate. Release the switch after more than
10 seconds. The serial server will reset to factory default settings.
Ethernet Connector
The Ethernet connection uses an RJ45 receptacle. The serial server is
connected to a standard Ethernet network drop using a straight-through RJ45
(male) Ethernet cable.
Note: Refer to Appendix D for connection pin-outs.
Serial Port Connectors
VESP211 Serial Servers feature two serial port connector configurations,
depending on the model:
 VESP211 and VESP211-232 use DB-9M connectors for RS-232, RS-422
and RS-485 connections.
