B&K 1785B, 1786B, 1788, 1787B Setting the output current 24H, Setting the communication address 25H

Page 22

7th byte	The highest byte of output voltage value
8th to 25th byte	System reserve
26th byte	Check sum

Note: We use 4 bytes of Hex number to represent an output voltage value. For example the output voltage value is 16.000V and the hex code of 16.000 is 0X00003EB0, so the 4th byte is 0XB0, 5th byte is 0X3E, 6th byte is 0X00, 7th byte is 0X00.

5. Setting the output current (24H)

1st byte	Start bit ( AAH )
2nd byte	Address (0~0XFE)
3rd byte	Command( 24H)
4th byte	To set the low byte of current value
5th byte	To set the high byte of current value
6th to 25th byte	System reserve
26th byte	Check sum

Note: We use 2 bytes of Hex number to represent an output current value. For example the output current value is 1.000A, the hex code of 1.000 is 0X03E8, so the 4th byte is 0XE8, 5th bye is 0XE3.

6. Setting the communication address (25H)

1st byte	Start bit ( AAH )
2nd byte	The current address of power supply(0~0XFE)
3rd byte	Command(25H)
4th byte	The new address
5th to 25th byte	System reserve
26th byte	Check sum

7. Reading the present current/voltage, maximum voltage, setup voltage/current and the states of power supply. (26H)

1st byte	Start bit ( AAH )
2nd byte	Address(0~0XFE)
3rd byte	Command( 26H)
4th byte	Byte 0 of present output current value
5th byte	Byte 1 of present output current value
6th byte	Byte 0 of present output voltage value
7th byte	Byte 1 of present output voltage

8th byte	Byte 2 of present output voltage
9th byte	Byte 3 of present output voltage
10th byte	Power supply’s state
