TROUBLESHOOTING

1. This module is designed to operate with Red Lion panel meters only.

Please make sure a Red Lion product is connected to either one of the

two serial ports for the gateway to be active.

2. The Ethernet port is equipped with data LEDs. If they are blinking,

the converter is active and the data is available at the port. Please

verify the receiving equipment is properly programmed.

3. If for any reason you have trouble operating, connecting, or simply

have questions concerning your new ICM8, contact Red Lion’s

technical support. For contact information, refer to the back page of

this bulletin for phone and fax numbers.

CONFIGURING THE ICM8

The ICM8 is configured using Crimson software. Crimson is available as a

free download from Red Lion’s website, or it can be ordered on CD. Updates to

Crimson for new features and drivers are posted on the website as they become

available. Crimson software can configure the ICM8 through the RS232/PG

port or USB/PG port. The USB/PG port is connected using a standard USB

cable with a Type B connector.

The driver needed to use the USB port will be installed with Crimson. The

RS232/PG port uses a programming cable made by Red Lion to connect to the

DB9 COM port of your computer. If making your own cable, refer to the “ICM8

Port Pin Outs” for wiring information.

ETHERNET COMMUNICATIONS

Ethernet communications can be established at either 10 BASE-T or 100

BASE-TX. The Crimson manual contains additional information on Ethernet

communications.

RS232 PORTS

The ICM8 has one RS232 port. The port can be used for programming or

communications.

RS485 PORT

The ICM8 has one RS485 port.

Note: All Red Lion devices connect A to A and B to B.
