Chapter 2 – Detailed Command Descriptions
2.0 Commands Overview
This chapter describes the commands available for controlling AJA's Ki Pro Ultra
and Ki Pro Ultra Plus digital video recorder/players.
NOTE: The 0xXX 0xXX values indicate the two bytes that are sent at the beginning of a
2. 1 Device Type Request – 0x00 0x11
The Ki Pro Ultra and Ki Pro Ultra Plus will respond with the following, depending
on the "35.6 RS-422 ID" setting:
ID Returned
0x20 0xA1
0x20 0xA0
0xE0 0x11
2.2 Stop – 0x20 0x00
Issuing this command during playback will cause the device to go into still
playback output. Issuing while still will cause the device to go into capture mode.
Issuing this command while capturing will cause the device to stop capturing.
Please note that transition from playback to capture may take up to two seconds
to complete. This command responds with ACK, but will do so before the
transport has changed state. Use the status bits to determine when the device
has actually stopped.
2.3 Play – 0x20 0x01
Issuing this command while still, will cause the device to go into normal speed
playback. Issuing this command while the device is in capture mode will cause the
device to go into playback mode and begin playing back at normal speed. Please
note there may be a delay of up to two seconds when switching from capture
to playback mode. This command responds with ACK, but will do so before the
transport has changed state. Use the status bits to determine when the device
has actually started playback.
2.4 Record – 0x20 0x02
Issuing this command while in playback mode will cause the device to enter
capture mode and begin capturing video at the current timecode. It will
always create a new clip (i.e. never record over a previously selected clip).
Upon completion of capture, this new clip will now be the single clip available
for playback. This command will respond with ACK, but will do so before the
transport has changed state. Use the status bits to determine when the device
has actually started capture.
