Emerson MONITORING OpenComms Manuel D’Utilisation

The firmware in the OpenComms NIC card can be updated to take 

advantage of the latest release of software that may contain feature 

enhancements, new unit compatibility or service patches. The firm-

ware is updated through the OpenComms NIC cards’ serial port, using 

a terminal emulation program like HyperTerminal in MS Windows 

Operating Systems. This procedure has multiple steps and requires 

that 3 files be downloaded to the OpenComms NIC card. The latest 

firmware can be found at this link on the Liebert Web site:

• PC capable of running a terminal emulation application, such as 

HyperTerminal.

• DB9 null modem or file transfer cable. (The correct cable will have 

at a minimum, pins 2 and 3 crossed at the ends.)

• Firmware update files (3 files total with extensions of .s19)

Read all instructions before to attempting a firmware 

download.

Turn off the power management on your PC or laptop to ensure
