1.4 Serial Communications
The controller UART must service communications from two sources: the RS-232 interface via the DB-9 connector on the
rear panel and the NIC interface. The NIC card controls a multiplexed that switches the UART between these two sources.
The controller firmware services three different command sets: one from the NIC card (which is not specified in this
document) and two from the RS-232 port. These two will be referred to as
human
and
machine
commands. The
human
interface is a verbose natural language interface that is intended for manufacturing and maintenance operations via a PC
running a terminal program attached to the port. Incoming character are typically echoed back to the terminal and a variety
of status messages are routinely sent, especially during power-up up and down sequences and when system anomalies
are detected and corrected. The
machine
interface is a terse command set. Incoming characters are not echoed and no
data is sent to the host unless requested.
The controller’s UART is selectable at 9600 or 19200 baud, 8-bits, no parity and 1 stop bit. The receiver is interrupt driven
with a 64 byte queue. The transmitter is polled and has no queue. XON/XOFF (^Q/^S) flow control is implemented in both
directions. The DB9-F connector is wired as a standard PC computer peripheral and may be connected to a PC running
an ASCII terminal program with a straight-through serial extension cable – not a null-modem.
1.5 Film Projector Lockout
The film projector lockout feature uses an external signal control either turning the projector on/off or closing/opening the
shutter depending if the film projector lockout mode has been set to lock out or power control mode. See the command
FPOL for more details.
1.6 Enhanced Color Correction (P7)
Commands have been included to utilize Texas Instruments’ Enhanced Color Correction Algorithm. When viewing
REC709 images use Entertainment Experiences' film look target color gamut by selecting index 5. When viewing
Tristimulus images use Entertainment Experiences' XYZ target color gamut by selecting index 6. See the ECC command
for more details.
