The Jorway Model 65 12 Bit NIM Input Register is a single width
Camac compatable module meeting the requirements of EUR4100e. The
Model 65 provides two functions;
1. The capability of entering external interrupts onto the Camac
dataway.
2. The capability of a fast coincidence latch.
Each of twelve fast input signals can be gated with a common strobe input to trigger a fast coincidence latch. The common strobe signal is applied to all channels of the module. With no strobe input connected to the module, the strobe line will go to a logic "1" level and the module functions as a interrupt register. The outputs of all twelve latches are wire "OR"ed to form an internal LAM signal. A signal Is generated on the modules L line whenever at least one interrupt has been received and the unit is enabled. The module generates a Q response whenever data is read out, and also whenever the LAM gate is inter- ogated ( provided the unit is enabled). Data of each storage register is read out on seperate read lines ( R1 through R12).
Module Specifications

Sensitivity -500mv
Input Impedance 50 ohms, +/-10% DC coupled
Strobe Input
Sensitivity -500mV

Dataway Controls
Z-S2 Resets interrupt flip flops; disables L and Q
lines and all signal inputs.
Dataway Outputs
Data Interrupt or Coincidence data for each of 12
latches, via R lines, R1 through R12.
Status
Q Q response always generated when data is read
( F2 ). Q also generated when LAM is interogated,
provided unit is enabled.
L L generated when at least one interrupt has been
received and the unit is enabled.
X X generated for all valid dataway commands.
Dataway Commands (all fully decoded)
N-F0-A0 Reads interrupt data onto the dataway,
generates Q response.
N-F2-AO Reads interrupt data onto the dataway,
generates Q response. Resets interrupt
FFs at S2.
N-F8-AO Interogates the "OR"ed LAM lines and
generates a Q response if enabled.
N-F10-AO Same as F8 but resets interrupt FFs at S2.
N-F24-AO-S2 Disables L, and Q response to F8 and F10.
N-F26-AO-S2 Enables L, and Q response to F8 and F10.
N-F25-AO-S2 Test, sets all 12 interrupt flip-flops.
SIZE: Single width CAMAC module.

CONNECTORS: 12 input connectors and 2 strobe connectors
all LEMO RA 00250 or equivalent.
