The HDi-250 is designed for control via serial commands via RS-232 or TCP/IP.  For convenience is also has front panel pushbuttons.

 

The BCD HDi-250 uses the "BCD1" Command Protocol, the same as used since 1982 and is in current use with BCD's TC-100, SB-100 and VC-16x controllers.  We will update this list from time to time when people have questions.  The full command set is listed in the Manual.

 

RS-232 Pinout:  The DB-9 connectors on the HDi-250 is wired as DTE so a straight-through 9-pin cable (M-F) from your computer requires a Null-Modem adapter.   The default Baud rate is 19,200 and may be changed and saved under software control.

 

Commands are 4-characters, terminated by CRLF (Carriage Return Line Feed).   The unit then  sends a prompt character ">" when it is ready to receive another command.
It is important that your control program wait for the ">" prompt before sending a command.

 

Some commands may have a numeric parameter.

 

The  MODE and STAT commands do the same thing -- they return the current status of the system.   MODE and STAT can take 3-4 seconds to return a value.  It is important that your routine wait for the ">" prompt after issuing any command.
STAT is a status query that returns a 4-character reply of system status.
MODE is a status query that returns a number.
