Signal Connections
Board signals are available on the 68-pin SCSI connector P1 and 40-pin header connectors J2, J3, J4, and J5.
Caution!
Avoid redundant connections! Make sure there is no signal conflict between the SCSI connector
pins and header connector pins. Failure to do so could possibly cause equipment damage and/or
personal injury.
Use the SCSI cable for optimal analog input settling time
To achieve the best analog input channel-channel settling time performance, connect your signals to the SCSI
connector (P1). If the J2 to J5 connectors are to be used, keep the interface cable as short as possible to
minimize settling errors.
