What is an M4e?

M4e refers to a new generation of M4. The difference between M4e and the older M4 version is

the communications spec. The M4e has RS-232 communications which do not require a special

cable. M4 ECU’s with serial numbers greater than 3000 are the new M4e and do not require the

special cable. Additionally no Software Upgrade Unit is required to upgrade the software version

on the M4e.
