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
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
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.
