Output Command Bytes
The drivers are closed-loop controlled, either for current or voltage. This byte
sets the output command as a percent of the programmed output limit value:
0 – 255 = 0% – 100%.
BDI
The BDI value is a percent of the battery state of discharge: 0–100 = 0–100%;
this value is gotten from the CAN master.
Inputs 1–13 Status Bytes
The 1356 /1356P monitors the thirteen digital inputs. The status of these inputs
in default PDO-MISO mapping is as follows.

Status Status Status Status Status
A status of 1 (bit set) indicates that the input is active (pulled high to B+). The
upper three bits of Byte 2 are unused and set to 0.
