JT 2149/MPV eMPV

The JT 2149/MPV and the JT 2149/eMPV are a 32 channel multi purpose DIOS/TAP pod modules/interfaces that can be plugged into any spare JT 2148 QuadPOD transceiver slot. The DIOS channels of these units I/O interface pods enable increased fault coverage and thus improved diagnostic resolution during boundary-scan testing. The principal difference between the two versions is the use of an extended case on the eMPV that allows standard 0.1″ connections to be used to access the TAP and static IO signals (see tab below)- on the standard /MPV unit these signals are available at the front face 0.05″ connector.


  • Provides I/O channels for increased fault coverage
  • Mounts conveniently in QuadPod slot
  • Improves 'diagnostic resolution'
  • IEEE Std. 1149.x TAP pod and DIOS in one module.
  • Available in standard size or ‘E’ extended version with additional 0.1″ TAP connections
  • Increases ‘stuck-at’ and open pin fault coverage on many designs
  • 40MHz TCK frequency rated
  • Retains full four TAP tester capability.

Increases fault coverage through improved I/O test access. Ideal for low channel count DIOS applications where space is limited. Can be reprogrammed with alternative (custom) SCIL function.

  • Plugs into JT 2148 QuadPOD transceiver slot
  • Includes stream-through TAP POD operation
  • Features 4 static I/O pins in addition to 32 synchronised DIOS channels
  • Programmable, multi-voltage
  • Channels accessed/bypassed in 2 blocks of 16
