Getting to Know Your IOLAN
z External Power Supply—For all IOLAN models, this can be an external AC power supply, DC
terminal, or power cord, depending on the model.
z Console/Serial Switch—Found on desktop models only (rack mount models have a dedicated
console port), this switch determines whether port 1 functions as a serial port or a console port. If
you have an extended temperature or I/O model, you will see two console switches.
Console/Serial Switch 1 is used to determine the console/serial setting for Port 1 and the
Console/Serial Switch 2 is not used.
z Reset—The inset RESET button will reboot all IOLAN desktop and rack mount models if
pushed in and released quickly. It will reset the IOLAN to factory defaults if pushed in and held
for more than three seconds. (The RESET button is not available on medical unit models.) You
can learn more about the Reset button in
Resetting the IOLAN to the Default Configuration .
z Serial Activity—All IOLAN models (except medical unit models) have an LED that blinks for
serial activity.
z Tx—Blinks with transmit serial activity. There is a Tx LED for each serial port.
z Rx—Blinks with receive serial activity. There is an Rx LED for each serial port.
z Ethernet—The Ethernet connector. SCS and SDS8/16/32C models have dual Ethernet.
