NIM 12-BIT INPUT REGISTER
FEATURES
12-Bit NIM Input Register
LEMO Front panel inputs
NIM External Strobe, via front panel LEMO
LAM Status for interrupt driven system
APPLICATIONS
General purpose data acquisition
GENERAL DESCRIPTION
The model 2351 is a single-width module that provides a 12-bit register
for holding NIM input data. The 12 NIM inputs and NIM Input Strobe are via
front panel connectors, RA 00250. LAM status is set at leading edge of the
strobe. If enabled and LAM status is set, a LAM requested is generated.
INPUTS
Data inputs must precede the strobe by at least 20ns. The strobe signal must be a minimum of 20ns wide. All inputs are active low (negative 12 to 36mA ). An open input is a logic 0 level.
