  • Page 8: Installation

    The default serial settings are 9,600 bps, no parity and 1 stop bit. If the serial settings are changed by Modbus function codes, the changes take place after repowering. The default Diver-MOD address is 1. If the slave address is changed by Modbus function codes, the change takes place immediately. © July 2017 Van Essen Instruments. All rights reserved.

    This register returns the remaining battery capacity of the connected Diver as a percentage of its full capacity. This value is only an indication! If the remaining battery capacity comes close to zero, the Diver needs to be replaced to prevent lost data! © July 2017 Van Essen Instruments. All rights reserved.
