TAP Pods
Excellence in typography is the result of nothing more than an attitude. Its appeal
comes from the understanding used in its planning; the designer must care.
In contemporary advertising the perfect integration of design elements often
demands unorthodox typography. It may require the use of compact spacing,
The JT 2149/DAF is a compact, mixed-signal (Digital/Analog/Frequency) measurement module for use in JTAG Technologies’ widely-used JT 2147 (QuadPod) signal conditioning interface. The DAF module has been designed to replace a regular TAP Pod and provides 28 measurement channels plus a clock generator. When connected to a circuit board via edge connector or test fixture/jig test pins, the module enhances standard digital boundary-scan tests by enabling a series of analog and frequency measurements to be made.
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.
The JT 2147/BO is the fixture-embedded variant of the JT 2147 QuadPOD high speed device programmer and flash programmer.
It comprises JT 2148 transceiver and four independent, programmable JT 2149 TAP PODs and provides signal conditioning for the DataBlaster series of boundary-scan controllers. Used for gang, parallel, fast testing / programming of devices.
This unit integrates the function of the classic QuadPod transceiver and four TAP pods onto a single assembly. This variant can also support 64 DIOS channels and SCIL functions.
The JT 2137 pod remains a popular choice for DataBlaster controller installations that require a compact signal conditioning pod embedded within a test fixture. The JT 2137 features four test access ports which together may be set for 5v or 3.3V TTL thresholds, although additional plug-in adapters are available that allow alternative thresholds to be set on a TAP by TAP basis (contact your local sales office for details). The 20-way 0.1″ IDC TAP headers comply with the standard JTAG Technologies 20-way pin-out and provide the additional flash programming controls Read/Busy and AutoWrite.
The JT 2147/eDAK is a new variant of the JTAG Technologies QuadPOD signal conditioning interface specifically designed for use within a MAC Panel ‘Scout’ mass interconnect interface. The unit integrates both the JT 2148 transceiver circuitry plus four independent, programmable TAP modules (two of type JT 2149 and two of type JT2149/MPV) on a single board that matches the MAC Panel Direct Access Kit (DAK) form factor. Overall this configuration offers four Test Access Ports, 64 Digital IO Scan channels and reconfigurable (SCIL) capabilities
The JT 2147/VPC is a variant of the JTAG Technologies QuadPOD signal conditioning interface specifically designed for use within Virginia Panel Corporation’s mass interconnect interface. The unit integrates both the JT 2148 transceiver circuitry, two independent, programmable TAP modules (of type JT 2149) and two TAP modules with I/O (of type JT 2149/MPV) on a single board that interfaces via the VPC QuadraPaddle connectors type G20x or G14x. Overall this configuration offers four TAPs, 64 Digital IO Scan channels and reconfigurable (SCIL) capabilities
