BK Precision 8500 - Command Details - Voltage and Current Limit Commands; Maximum Current Limit Commands

Byte
offset
Meaning
5 Upper low byte of maximum voltage.
6 Upper high byte of maximum voltage.
7-24 Reserved
Example: Suppose you want to set the maximum voltage to 16.23V. Since 1 represents 1mV,
therefore 16.23V translates to 16,230 in decimal. With 4 bytes in Hex, that would be 0x0003F6A.
Since the bytes are ordered in little-endian format, 0x6A would be the 3
rd
byte, 0x3F the 4
th
byte,
0x00 as 5
th
byte, and 0x00 as the 6
th
byte.
0x23 Read the maximum voltage allowed
Byte
offset
Meaning
3 Lower low byte of maximum voltage. 1 represents 1 mV.
4 Lower high byte of maximum voltage.
5 Upper low byte of maximum voltage.
6 Upper high byte of maximum voltage.
7-24 Reserved
0x24 Set the maximum current allowed
Byte
offset
Meaning
3 Lower low byte of maximum current. 1 represents 0.1 mA.
4 Lower high byte of maximum current.
5 Upper low byte of maximum current.
6 Upper high byte of maximum current.
7-24 Reserved
Example: Suppose you want to set the maximum current to 3.12A. Since 1 represents 0.1mA,
3.12A translates to 31,200 in decimal. With 4 bytes in Hex, that would be 0x000079E0. Since the
bytes are ordered in little-endian format, 0xE0 would be the 3
rd
byte, 0x79 the 4
th
byte, 0x00 as 5
th
byte, and 0x00 as the 6
th
byte.
0x25 Read the maximum current allowed
Byte
offset
Meaning
3 Lower low byte of maximum current. 1 represents 0.1 mA.
4 Lower high byte of maximum current.
