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.


Common Commands 


RECS means RECord Start.  It starts recording.
         STAT=RCRD.  MODE=16


STOP makes it stop.
         STAT=PTHR (pass through) MODE=25


PAUS makes playback or recording PAUSe.
        STAT=STFW (step fwd)  MODE=1 


PLAY makes it play.
         STAT=PLAY   MODE=10


If the unit is in Pass-Through or Loop-Through mode (video in goes through to video out). PLAY makes it go to the TITLe menu.
If the unit is in PAUSe mode, playback resuumes.


STAT is a query for current transport status. 
        STAT returns a 4-character message like STOP, PLAY, RECD


MODE is the same as STAT but returns a 2-digit number. 
       Mode 10 is PLAY.  MODE 0 is STOP/PTHR. 



FRAM returns the current disc playback position as an integer frame number
