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.
Note: 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 directi on 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:
zSerial Interface to EIA-232
zSpeed to 9600
zFlow Control to No
zBits to 8
zStop Bits to 1
zParity to None
Console mode als o di splays 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.
Note: When the console switch is in the on position, the Power/Ready LED will blink green.
Serial Mode
Serial mode is used when the IOLAN acts as a communications server, or anytime yo u 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/in format ion you will get in Console mode.
