E Setting Jumpers

Appendix E

Introduction

The IOLAN contains jumpers that you might need to set before you configure it and put it into production. You can set the power out pin, pin 9, to a fixed 5V DC output or to the external adapter output; this can range from 9-30V DC (if an external adapter is shipped with the IOLAN, it has a 12V DC output); maximum output power is 1 (one) watt per a serial port. By default, the power out pin is set to no power. You can set the IOLAN line termination to on or off (this is off by default) if you are using EIA-422/485 (not applicable for I/O models).
