Cable Information Part No.
Adapter cable for the DaqBoard/200A P2 or P3 port CA-60
Ribbon cable (6 ft) with a female DB37 connector on one end, unterminated
on the other. This cable provides convenient wiring to DaqBoard P1, P2, &
P3 ports.
Note: For a cable distance of more than 6 feet, attachment to a
DaqBoard/200A P2 or P3 requires the use of an optional
CA-60 cable.
