Using the Nexus External Displays

6.1: Overview

Electro Industries offers four external displays for use with the Nexus 1250/1252. The P40N, P41N and P43N are LED displays that provide easy-to-use access to the information stored in the Nexus 1250/1252. The P60N is our Touch Screen Display, which provides easy access to Nexus 1250/1252 readings and information combined with a graphical touch screen presentation.

Plug one of the Nexus External Displays into Port 3 or 4 on the Nexus Meter, using the cable supplied. The Displays operate at 9600 baud; Port 3 is factory-set to 9600 baud (see Chapter 5 for communication details). To use the Displays on another port, configure that port to operate at 9600 baud, using the Communicator EXT Software; see the Communicator EXT User Manual.

6.2: Nexus P40N, P41N and P43N LED External Displays

The Nexus P40N LED External Display can be used alone or it can serve as the Master for this grouping of displays. The P40N prepares the data for the Slave displays, the P41N and the P43N. Once a second, it sends a request to the Nexus meter. All necessary data for the Slave displays is returned to the Master display upon this request and the Master sends the data to the Slaves in the proper format.

The Nexus P41N and P43N Slave displays listen to the Master and display and update values on the screen when they receive proper data. These displays have no keypads. Data can only be received; it cannot be changed. If there is no data for more than 5 seconds, “Communication Lost” will appear on the bottom of the screen. The following data is displayed when received:

•Amp Display (P41N): Amp A, Amp B, Amp C

•Power Display (P43N): Watt, VAR, PF
