The G4D32EB2-UPG replaces a G4RS brain board on a G4D32RS mistic
digital rack. This part number includes a G4EB2 brain and a metal cover designed to fit the brain’s Ethernet connections.
The G4D32EB2-UPG provides physical compatibility, I/O module compatibility, and field-wiring compatibility with the G4D32RS mistic
brick. However, this brain uses a different protocol—OptoMMP instead of mistic
—and different commands. If you replace a G4RS with the new part, you will need to change your program in order to communicate with the unit.
For a complete Ethernet version of the G4D32RS brick (brain, cover, rack, and regulator), see the G4D32EB2
