Getting to Know Your IOLAN
38 IOLAN SDS/SCS/STS User’s Guide, Version 3.6

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 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 mod e 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.

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/in format ion you will get in Console mode.

Dedicated Console Port: Rack Mount Models

The rack mount IOLAN models have a dedicated Console port, lo cated on th e LED side of the
IOLAN. You can use the supplied Administration cable (with the supplied RJ45JDB9F adapter if
needed) to connect a terminal to the Consol e/Admin port to view diagnostic informati on and/or
configure the IOLAN using the Menu or Command Line Interface (CLI). You can configure the baud
rate and flow control of the dedicated Console port.
Note: The SDS T (Extended Temperature) models have two switch es, 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 cycle on and off
(flashes green).
