Getting to Know Your IOLAN

Located at the back of the desktop IOLAN models is a switch that controls whether serial port 1 is in 
Console or Serial mode. 

The SDS T (Extended Temperature) models have two switches, Switch 1 is used for 
Console/Serial mode and Switch 2 is unused.

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 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

 to 

z

 to 

z

 to 

z

 to 

z

 to 

z

 to 

Console mode also displays extra system messages. 

Serial port 1 will ignore any 

 settings when in Console mode, so you need to turn Console 

mode off to use serial port 1 in your network. 

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

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.
