JT 2702/DDC DIOS adapter

JT2702/DDC (Dual DIMM Carrier) is a DIMM DIOS accessory product. It is typically used in custom test adapters or fixtures where a large number of digital I/O channels are required with a minimum space overhead.

By populating the JT 2702/DDC with one or two of JTAG Technologies DIMM/168 format DIOS units, the user can build either a 128 or 256 channel I/O system. Since the units can also be serially linked, a channel count in excess of 1000 IOs is easily achieved at a relatively low cost. Access to the channels is via eight standard 40-way 0.1″ IDC connectors.
