board. A 2 pin header can be soldered in the mother board with a connector at
the end of the wires for easy disconnect.
This external switch should be momentary SPST and will operate in parallel with
the front panel switch. Either one can be used. The front panel LED always indi-
cates the currently selected input.

nents from its waveform. However some equipment may not be able to read
time code if its rise time is too long.
The SR-28 has three preset rise times for its output waveform: 25 µsec

.
As a general rule, if time code is patched directly into a reader, use the square
