DESCRIPTION
The I/0 612 Parallel Input/Output Register is a single-width CAMAC
module which contains two 24-bit registers to transfer data between
the crate Dataway and an external device. The I/0 612's external data
lines are bi-directional. When a register bit is cleared to zero, the
corresponding external line can be read as input data from the
external device.
Simultaneous input and output operation is possible using one register for input and the other for output. This simplifies both hardware and software requirements by eliminating the need to install and address independent modules.
Data outputs are available on two 31 pin front panel connectors, one for each register, and 48 front panel LED's provide visual display of both registers.
Data outputs are negative true, open collector drivers capable of sinking 37 milliamps at +5 volts. An external strobe signal for each register indicates when it has been overwritten.
APPLICATION
Transfers up to 48 bits of data between the CAMAC Dataway and an
external device.
