ABOUT 3344
The Model 3344 is a single-width CAMAC module that interfaces the CAMAC
Dataway to as many as four separate RS-232 serial ports. Sixteen data rates
are available: 50, 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2000, 2400,
3600,4800, 7200, 9600, and 19,200 Baud. Data rates are programmable from
the Dataway on a per channel basis, as are the number of data bits (from five
to eight), the number of stop bits (one or two) parity error checking, and
control character recognition capabilities.
Two 1024 character buffers are provided for each channel, one for input and
one for output. These buffers provide elastic communications between the
Dataway and remote devices. As a diagnostic aid, input can be echoed back to
the output as well as sent to the computer. The echo feature is programmable.
On output block transfers, the buffer is filled by performing Write
commands until a Q = 0 response is detected. A Q = 0 response indicates that the
buffer is full. The module will continue to transmit the block of data at
its selected Baud rate until the output buffer is empty.
