This is a longer version of our custom RJ-45 to USB update cable for LM,AM,BM, and CM series FSI monitors. All LM,AM,BM,CM series FSI monitors come with a short update cable at no additional charge, but this longer cable can be particularly useful if updating harder to reach or larger monitors. It is also extremely useful for those using the DIT LUT capabilities on newer CM and BM series units as it allows the computer sending the custom 3D LUTs to be further away from the monitor.
