Subject: adding 2nd ADC and TDC to crate 
Hi folks:

we've been running midas-1.9.5 for a few years here at Regina.  We are now
working on a larger cosmic ray testing that requires a second ADC and second TDC
module in our Camac crate (we use the hytek1331 controller by the way).  We're
baffled as to how to set this up properly.  Specifically we have tried:

frontend.c

/* number of channels */
#define N_ADC  12 
(changed this from the old '8' to '12', and it seems to work for Lecroy 2249)

#define SLOT_ADC0   10
#define SLOT_TDC0   9
#define SLOT_ADC1   15
#define SLOT_TDC1   14

Is this the way to define the additional slots (by adding 0, 1 indices)?

Also, we were not able to get a new bank (ADC1) working, so we used a loop to
tag the second ADC values onto those of the first.

If someone has an example of how to handle multiple ADCs and TDCs and
suggestions as to where changes need to be made (header files, analyser, etc)
this would be great.

Thanks, Zisis...

P.S.  I am attaching the relevant files.
