SYNTAX

(XPVD-SEND-COMMAND "SR2911:")

DESCRIPTION

Wraps STX/ETX envelope around given string and sends to Panasonic, via port specified by last XPVD_INITIALIZE-SERIAL-PORT.

See 'Panasonic Operating Instructions' for documentation of commands. In general, the format consists of a two-character opcode. Any numeric arguments follow the opcode, each decimal-coded in ASCII and terminated by a ':'.

NB: After switching on NTSC signal, we normally give Panasonic two seconds to synch to the signal, then do "ON" and "AC".

NB: Recording is normally done by the above sequence followed by SR<startframe>:, RM<framesToRecord>:, 6-sec sleep while it videosynchs again, GS<framesToRecord>

A quick summary of some common commands:

ON         Set 'ONLINE'.  Commands are ignored when offline, except 'ON'.
OF         Set 'OFFLINE'.
OL         Online-Lock: Disable front-panel 'ONLINE' button.
AC         All Clear.  Clear input/output buffers, etc.
