The CAMAC 064 module provides eight gates which may be individually controlled by externally applied set and reset inputs. The set and reset inputs, terminated in 100 ohms, are compatible with CAMAC 177/377 module timing channel outputs. Gate outputs are available at the front panel and rear I/O connector, each sourced by separate 74128 drivers. Gates 1 thru 4 may also modulate four separate Gated Input signals. The developed Gated Output signals are sourced by 74128 drivers and are available at the rear I/O connector. The Gated Input signals are also terminated in 100 ohms. All input and output signals are positive logic. The status of all Gates, Gated Input, and Gated Output signals is provided by a single CAMAC read operation. There is no provision for individual set or reset of a gate by CAMAC operation. All gates are reset by power up or by a programmed CAMAC operation.
The module is also capable of receiving TCLK and providing decoded clock events as sets or resets to individual gates. Two on-board PALs can provide up to sixteen decoded outputs and may be individually programmed as necessary. Implementation of this feature is by wire jumper to the appropriate set, reset, or gated input line after removal of the 100 ohm terminating resistor.
An input may operate on more than one gate. Such facility would also be by on-board wire jumper associated with the removal of unwarranted termination resistors.
Given the customizing options provided by the module, caution is advised when performing in-service replacement.
