I/O Modules

The JT 2111/MPV is a 64 channel boundary-scan digital I/O scan module enclosed in an impact resistant housing. The module is designed to test and control edge connectors, on-board connectors and logic clusters in boundary-scan applications. Multiple modules can be connected serially to increase the number of I/Os. Available with 96-pin DIN 41612 connectors and 20-pin 0.1″ pitch IDC connectors.

This JT2111/MPV DIOS module is also available through our webshop.

The JT 2122/MPV DIOS (digital I/O scan module) increases the coverage and improves the diagnostic resolution of boundary-scan testing by extending test access to connectors and/or test points. JT 2122/MPV DIOS provides bi-directional parallel-scan access to up to 128 or 133 I/Os in a standard DIMM-168 module.

The TAP signals can be accessed via the ‘fingers’ of the 168 pin module connector or a separate 10-pin connector. A TAP-out can be used to daisy-chain to another DIOS module or to a scan chain on the target board.

The JT2702 Digital 256 channel JTAG I/O module,

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 (digital) 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.

The JT 2127/Flex  STM memory socket tester  is a family of hardware adapters specifically designed for the testing of of PCB-mounted DIMM & SODIMM sockets using a JTAG/boundary-scan controller and supporting software. The testing of memory sockets has always been troublesome for test and production engineers using JTAG/boundary-scan systems. Even when it is possible to create memory writes/reads from a boundary-scan compliant access device on the UUT (Unit Under Test), the initialisation process may fail leaving you with little diagnostics information. What’s more it can still be uncertain whether fault lays with the DIMM module itself or the socket. Using the new JT 2127-Flex system from JTAG Technologies you get pin-point diagnostics from a known-good test interface so you can be certain that your socket is soldered correctly.
