<fl> is a single character integer code representing current filter
type (see $FL command).
<ex.wavelength> is fixed format (xxx.x) representing the
excitation monochromator position in nm.
<em.wavelength> is fixed format (xxx.x) representing the
emission monochromator position in nm.
<speed> is a 4 digit integer representing speed in nm/min. A
leading minus is given for negative speeds.
<response> is a 3 digit integer representing current filter
response number.
<ex.slitwidth> is fixed format (xx.x) representing the excitation
slit width in nm.
<em.slitwidth> is fixed format (xx.x) representing the emission
slit width in nm.
<gate> is a 5 digit integer representing current phosphorescence
gate time, units 0.01 ms.
<delay> is 6 digit integer representing current phosphorescence
delay time, units 0.01 ms.
<flashcount> is a 2 digit integer representing current number of
flashes per phosphorescence data collection cycle.
<cyc.time> is a 5 digit integer representing current data
collection cycle length in ms (may be zero in fluorescence mode
to indicate default 1 mains period).
Command: WAIT FOR EXTERNAL SIGNAL
Syntax: $WE signal
Description: Waits for a transition on one of the external digital inputs:
0 = positive transition on EVENT line, 1 = positive transition on
START line.
NOTE: On earlier issue instruments the EVENT line is labeled REMOTE START and
the START line is labeled REMOTE INTEGRATE.
