 BC-092 IP-EP201 (softGlue fpga) Header
==============================================

The BC-092 board is a compact module designed to connect
directly to the 50-pin header on and Industry Pack carrier,
whose corresponding slot is populated by the Acromag IP-EP201
FPGA board.  IP-EP201 is used at the APS to provide a control-
lable fpga for the synApps "softGlue" application.

BC-092 simply puts 100 Ohm terminating resistors in-line with
all 48 I/O signals, and puts gnd between each I/O signal.
The signals on the 50-pin ribbon are laid out as follows:

  |    |    |    |    |    |
 ch1  gnd  ch2  gnd  ch3  gnd  . . .
 
This layout is designed to optimize the system to reduce
the effects of crosstalk and noise, while giving the user
the flexibility to connect their "user" I/O interface (Lemo
breakout, screwterms, etc.) at the end of a ribbon cable. 
I have tested this setup with an 8-ft ribbon cable, up to 10MHz.
 
The 100 Ohm resistors are SIP packages, inserted into sockets.
One may easily replace them with another value if needed.
