7.5.1 Communications Menu Item Descriptions

Data Stat, DatPortBaud, Data Parity, and DataPortAddr
These menu items apply only to the Data Port located on the front of the MJ-4 Control Panel, and do not require
modification.
Reg Id (Regulator Identification)
This item allows you to uniquely identify each regulator in the system. The Regulator Id is accessible as a data item
via the communications module for most of the protocol selections.
Protocol
This item defines the protocol selection for the MJ-4 Communications Module. The selections are listed in Table
7-4.
2200NOA is a variation of the 2200 protocol with the address field suppressed. It is provided for testing the MJ-4
Communications Module with the MJXplorer™ software. The SPECIAL item allows a new protocol handler to be
included in the Communications Module code without forcing a modification to the Main Processor code (for the
protocol selection front panel screen).
Comm Baud
This menu item defines the data rate for the MJ-4 Communications Module. The standard asynchronous
communications data rates are available for selection. For proper communications, the Comm Baud setting must
match the baud setting of the other communicating device(s) in the network.
Comm Parity
This configuration item defines the parity selection for the communications module. For proper communications,
the Comm Parity setting must match the parity setting of the other communicating device(s) in the system.
