Getting to Know Your IOLAN

Console/Serial Switch

Located at the back of the desktop IOLAN models is a switch that controls whether serial port 1 is in

Console or Serial mode.

Look at your model to verify the direction of the ON switch position. ON indicates that serial port 1

is in Console mode; otherwise serial port 1 is in Serial mode.

Console Mode

Console mode is used when you have a direct connection between a serial device (like a terminal or a

PC) and the IOLAN, accessed by the admin user to configure/manage the IOLAN. Console mode

automatically sets serial port settings as:

z Serial Interface to EIA-232

z Speed to 9600

z Flow Control to No

z Bits to 8

z Stop Bits to 1

z Parity to None

Console mode also displays extra system messages.

Serial port 1 will ignore any Serial Port settings when in Console mode, so you need to turn Console

mode off to use serial port 1 in your network.

Serial Mode

Serial mode is used when the IOLAN acts as a communications server, or anytime you are not

connecting directly to the IOLAN to configure it. You can connect directly to the IOLAN in Serial

mode, but the IOLAN will not display all the messages/information you will get in Console mode.

Note:

The SDS T (Extended Temperature) models have two switches, Switch 1 is used for

Console/Serial mode and Switch 2 is unused.

Note:

When the console switch is in the on position, the Power/Ready LED will blink green.
