This unit
The JTAG Technologies JT2149 TAP Pod is a modular boundary-scan interface that connects JTAG controllers to target boards for test access port (TAP) operations and in-system programming. The unit transmits standard TAP signals
TDI, TDO, TMS, TCK, and TRST - alongside control signals for AutoWrite and VPP_enable functions. It integrates a flash Read/Busy line monitor and two user-configurable outputs (User0 and User1) for custom test operations. Available as a standalone module or as part of the JT2147 QuadPod system, the JT2149 reduces maintenance costs through field-replaceable modular construction.
Technical Specifications Connectors and Signal Distribution
20-way 0.1" IDC connector: 10 dynamic signals (TAP, AutoWrite, VPP_enable, User0, User1), 9 signal grounds, 5V supply
8-way SIL IDC connector: 4 static I/O lines, 4 signal grounds
0.05" 26-way front-edge connector: all dynamic signals, static I/Os, 11 signal grounds, 5V power Remote Operation
Optional one-meter extender cable (JT 2131/47) permits remote siting without performance degradation
Key Features
Full TAP signal support for JTAG boundary-scan and in-system programming workflows
Flash memory operation monitoring via dedicated Read/Busy input
Static I/O lines for relay control and switch closure detection
User-defined outputs enable custom control logic integration
Modular form factor allows independent unit replacement
Module Variants JT 2149/DAF
28 measurement channels with integrated clock generator
Extends digital boundary-scan with analog and frequency measurement capabilities JT 2149/MPV (-001)
32 channels of DIOS (Digital I/O Synchronized); up to four units provide 128 total DIOS channels in QuadPod configuration
2 × 20-way 0.1" IDC connectors for signal access

JTAG Technologies JT2149 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the JTAG Technologies JT2149. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common JTAG Technologies JT2149 faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.
