Power Supply BL-U1

Example: When the command to shift to the setting mode (SSET) is sent to the BL series

of ID No. 3:

1. From the host computer:

2. Loopback data:

3. From the BL series:

If an incorrect ID number is specified, an incorrect format is used to send a com-

mand, or a data transmission error occurs (checksum is incorrect), the BL series

sends back no response. You will need to design a program so that the same

command is sent again (Retry) if the BL series sends back no response within a

specified period (Timeout).

With RS-232C or RS-422A communication, the BL series sends back no data in

response to some of the direct control commands (e.g. LOG<CR>). With the mul-

tidrop link, however, the BL series sends back the following data in response to

those commands.

During normal processing: OK

When error occurs: ERR**

** indicates an error code (see p. 70).

[STX] 011 03 SSET 22 [ETX]

[STX] 009 03 OK 3E [ETX]
