Memory Address For Data Links - Sharp JW-21MN User Manual

Chapter 8: Memory Address on the ME-NET
The ME-NET employs a system for addressing individual memory banks in all of the connected
equipment by allocating address throughout the ME-NET. Therefore, the top address in any link area
which will contain in the data link parameters and memory addresses used for computer link
instructions must be a valid memory address in the ME-NET.
The relationship between memory addresses in Sharp PCs (JW20/JW20H/JW30H) and those on the
ME-NET are shown below.
