TB-100 Terminal Connector Option
The TB-100 Terminal Connector option can be used to connect all signal I/O lines that
are associated with a DaqBoard/500 or /505. TB-100 can connect to either board’s 68-
pin SCSI III connector via a 3 ft., 68-conductor cable (CA-55 or the shielded CA-56); or
via a 6 ft. shield cable (CA-56-6).
TB-100 Pinout The “Pin” column refers to the pin no. on the 68-Pin SCSI III Connector.
