WARNING

Always turn the computer power OFF and unplug it before connecting or discon- necting a screw terminal panel or a cable to the PCI card. Failure to do so could result in electric shock, or equipment damage.

CAUTION

The discharge of static electricity can damage some electronic components. Semiconductor devices are especially susceptible to ESD damage. You should always handle components carefully, and you should never touch connector pins or circuit components unless you are following ESD guidelines in an appropriate ESD controlled area. Such guidelines include the use of properly grounded mats and wrist straps, ESD bags and cartons, and related procedures.

Overview

DaqBoard/500 Series boards communicate [external from the host PC] through a 68-pin SCSI III connector. An optional TB-100 terminal board offers convenient screw-terminal connections for all signal I/O.

Pinouts for both the DaqBoard/500 Series connector and the TB-100 follow.

The TB-100 option can be easily connected to a DaqBoard/500 or DaqBoard/505 via one of three

68-conductor cables. These are: CA-G55, a 3 ft. unshielded cable; CA-G56, a 3 ft. shielded cable; and CA-G56-6, a 6 ft. shielded cable.
