  10 BASE-T/100 BASE-TX ETHERNET
GENERAL DESCRIPTION
The ICM8 is designed to act as an ethernet gateway offering multiple 
protocol conversion for Red Lion panel meters. With two serial ports (one 
RS232 and one RS485) and a 10 Base-T/100 Ethernet Port, the unit performs 
protocol conversion, allowing Red Lion panel meters to communicate 
seamlessly to the ethernet network. Programming the unit can be accomplished 
via the RS232 or the USB Port using Crimson Software. It is important to note 
that this device is designed to function with Red Lion panel meters and will not 
offer protocol conversion if a Red Lion Product is not connected to at least one 
of the serial ports.
The ICM8’S DIN rail mounting saves time and panel space and snaps easily 
onto standard top hat (T) profile DIN rail.
SOFTWARE
The ICM8 is programmed with Windows
®
 compatible Crimson software. 
The software is an easy to use graphical interface which can be purchased as part 
of a kit that includes a manual and cables, or downloaded free of charge from 
www.redlion.net.
