5.5 Communications Module Configuration (reference 4.7)
Prior to using the MJ-5 Communications Module in the network, the communications module needs to be
configured properly for communications. The < COMMUNICATIONS > menu of the MJ-5 Control Panel provides
all the required communications configuration items for the communications module. Table 7-4 lists the
communications menu items in the order in which they appear on the MJ-5 Control Panel; default settings are in
bold.
1.
Program the communications parameters of the MJ-5 Communications Module by pressing the Menu key twice
to display the < METER > menu.
2.
Then press the left arrow key until the < COMMUNICATIONS > menu appears. Use the up and down arrow
keys to access the individual menu items.
3.
To change the value of the parameter, press the Change key, and then use the arrow keys to toggle the choices
or set the value for the parameter. Press the Save key after changing the value of a menu item to enter the
changes, or press the Cancel Reset key to cancel the change.
Each time a configuration menu item is changed, the communications module is reset by the main MJ-5 Control
Panel. This reset is part of the process of updating the communications module with the new configuration.
