We (Texas Region) bought a new system with laser photocells back in
2000 or so. At that time, the photocells turned out to have issues if
they got too hot (outside temps in the triple digits did it every
time), and we went back to the Banner IR units that JACircuits had
supplied for years. We're back to laser units now. AFAIK, the earlier
problem has been fixed.

I agree with your thinking. If a cable is run over, it's usually
history, and it won't matter what kind of cable it is. If the damage
is near one end, you can cut off that part and reterminate it. BTDT,
many times. If a cable is damaged in the center and you don't have a
use for a half-length cable, it's time for a new one.

They're just 3-pin XLR connectors, available at Radio shack for <$5.00
each. This is the standard connector for microphone and line-level
audio signal cabling worldwide. There's one nonstandard provision that
is required for the cable to work with the JACircuits timer: Pin 1
(common) at the timer end of the cable _must_ be jumpered to the shell
(there's a solderable lug that contacts the shell when the connector
is assembled). If this weren't necessary, you could just go to a music
store and buy microphone cables of the required length.
