GB / SB GET / SET BAUD RATE

Used to set the SSD Baud Rate. Values other than the following are ignored.

Value

Baud Rate (bit/s)

0

9600

1

14400

2

19200 (default)

3

38400

4

57600

5

115200

6

230400

7

460800

8

921600

Notes: Baud rate is changed immediately. Connect using new baud rate and use RESET COMMAND (RS0F) to save current settings

to EEPROM. If unable to connect, reboot to restore the previous setting.

Value is an unsigned Int16. BAUD RATE default is: 2

Example: To set Baud Rate to 115200 bps

GD / SD GET / SET READING DELAY

Used to set the delay between readings automatically sent via RS485 (Not available with MODBUS). Autosend must be enabled (see

SET MODE bit8). Note: If the Conversion Time is greater than the reading delay, the shunt will send the same value until the next set

of readings is available. For readings faster than 5 ms use SET MODE Bit7 Send on Conversion. This will send the data as soon as

it’s available. Valid Range: 5 ms to 60000 ms.

Value is an unsigned Int16. READING DELAY default is: 1000 ms

Example: To set Reading Delay to 100 ms
