1. DIS700 Introduction

LiBat™ DIS700 is a 7-inch touchscreen display for a LiBat™ BMS. It reads the battery status that the BMS sends over CAN and shows it on five pages: the battery at a glance, every module, the cells of a module, the BMS events as coloured tiles and the details of the BMS and the DIS700. A status LED on top turns green or red with the battery state, and an on/off button switches the DIS700 on and off. A phone or a laptop can reach the same data: the LiBat Dashboard mobile app over Bluetooth Low Energy, a browser over the Wi-Fi of the DIS700 (4.6 and 4.7). The DIS700 is not a BMS; it only presents the data that the BMS sends. How it is connected is on the connection page, what it shows on the operation page.

Note

The DIS700 comes without an enclosure (order code DIS700) or in an enclosure on two rotating mounting brackets (DIS700-E). The figures of this wiki show the DIS700-E; the connector and the screen are the same on both.
