SPIO CO Alarms Interface Pinout
The 8-foot (2.4 meter) CO alarm cable shipped with the chassis supports redundant SPIO card installations. This "Y"
cable has two Molex connectors on one end that are keyed to fit into the CO Alarm interfaces in one direction only.
Each connector mates with one of the side-by-side SPIO cards. On the opposite end is a 9-pin terminal block that you
can mount to the telco cabinet or equipment rack frame.
The following figure and table display this cable assembly and its pinouts.
