JTAG Probes for ARM
ADA-JET-ARM20 and ADA-JET-ARM14
Signum JTAG probes for ARM provide a physical interface between Signum emulators for the ARM processor
and ARM target boards. These probes have 20-pin (ADA-JET-ARM20) and 14-pin (ADA-JET-ARM14)
double-row, polarized, .100" × .100". (2.54 mm × 2.54 mm) female connectors. Signum JTAG probes come
with a 30.5 cm (12 in.) cable. The layout and dimensions of the probes are shown in Figure 1 through Figure 10.

ADA-ARM-SWD
The ARM-SWD probe supports both ARM and Cortex boards at voltages 0.8V to 5.0V. It must be used when
Cortex Serial Wire Debug or Cortex Serial Wire Output operation mode is required.
In addition to a standard 20-pin double-row female ARM connector, this probe has a 20-pin and 10-pin high-
density Cortex connectors. Only one connector can be used at a time. The ARM connector, mounted
underneath the probe, has the pinout of the ADA-JET-ARM20 probe (Figure 12). The pinouts of the 20-pin
and 10-pin Cortex connectors are shown in Figure 13 and Figure 14, respectively. The two high-density cables
included with the probe provide a link between the Cortex connectors and the target board (Figure 11).

ARM Cortex Probe
ADA-ARM20-Cortex
This passive adapter allows you to interface any Signum JTAGjet emulator that uses the 20-pin JTAG probe
for ARM (ADA-JET-ARM20 or its low-voltage variant ADA-JET-ARM20-LV) with a Cortext-M target board.
Both 20-pin and 10-pin high-density Cortex connectors are supported, but only one of them can be used at a
time. The ARM connector of the probe has the pinout of the ADA-JET-ARM20 probe (Figure 2). The pinouts
of the 20-pin and 10-pin Cortex connectors are shown in Figure 13 and Figure 14 (page 5), respectively.

Caution: Voltages higher than

The Signum JTAG probe for OMAP devices, ADA-JET-TI14, provides a
physical interface between Signum emulators for the OMAP processor and
OMAP target boards. This probe is the same as that for the Texas Instruments
TMS320 devices. It has 14-pin double-row, polarized, .100" × .100". (2.54 mm ×
2.54 mm) female connectors. The pinout and dimensions of the probe are shown below (Figure 18 through
Figure 20).

Your emulator can also be ordered with a low-voltage, or—if so desired—with both standard and low-
voltage—variants of the probe for OMAP devices. These two variants have slightly different dimensions
(Figure 19). The voltage range of the low-voltage probe is 1.8 – 3.3V (± 10%).

JTAG TMS320 Isolation Probe
ADA-ISO-TI14
The JTAG Isolation Probe for TMS320/470/570 Devices from Texas Instruments is a full isolation JTAG
probe for JTAGjet emulators which reduces the chance of damage to the emulator associated with ground
loops, voltage spikes, electrostatic discharge (ESD) and noise on power and ground lines generated by high-
current motors and other machinery.
The probe fits between the JTAGjet emulator and the user’s target board equipped with the Texas Instruments
style 14-pin JTAG connector. The distinctive features of the ADA-ISO-TI14 include
•
•
•
•
•
•
Support for all TMS320C2000, C5000, C6000, OMAP, DM and TMS470 / 570 devices
Operating JTAG voltage from 3.0 V to 5.0 V (± 10%)
Galvanic isolation up to 1000 V (peak)*
50kV/µs transient immunity (typical) on JTAG lines
ESD protection of 8kV on contact and 15kV air discharge
Maximum JTAG clock rate up to 15MHz
*
Important Notice The continuous normal operating voltage across the isolation barrier
can be 0 – 60VDC. The isolation voltage only represents a measure of immunity to
transient voltages—the probe should never be used as an element of a safety isolation
system. This probe can be expected to function correctly with a few hundred volts offset
applied continuously across the isolation barrier. However, the circuitry on both sides of
the barrier is then regarded as operating at an unsafe voltage and additional
isolation/insulation systems must be used in accordance with safety standard
requirements.
Signum Systems shall not be liable for any damages related to the use of this probe.

Isolation Probe for TI-14 JTAG with an Optional
External Power Input
ADA-ISO-TI14-E
The isolation probe for TI-14 JTAG with an auxiliary power input ADA-ISO-TI14-E should be used in
applications where the target board does not have enough current (about 150mA) to supply the isolation probe.
When used with external power adapter, this probe reduces the current taken from the target board to
approximately 1 mA.
The ADA-ISO-TI14-E probe requires a 5.0V VDC external power source to be connected to the J1 socket.
The polarity for the J1 socket is center pin positive (+), outer collar negative (−). Reversed polarity may damage
some electronic devices. If the external power supply is not connected, the isolation probe will automatically
take power (about 150mA) from the target board. The auxiliary power adapter is not included with the isolation
probe.

Compact TI 20-pin JTAG probe for DaVinci
ADA-JET-CTI20
The Signum JTAG ADA-JET-CTI20 probe provides a physical interface between the Signum JTAGjet-
eBinder emulator and DaVinci, DM and OMAP target boards. This probe has 20-pin receptacles. The pin-to-
pin X spacing is 0.10 in., Y spacing 0.05 in. The female connector on the probe is SAMTEC RSM-110-02-S-D.
This is a low votage probe operating in the 1.8 – 3.3V (± 10%) range. Figure 30 shows the probe’s pinout.

TABLE 5 The allowed settings of the ADA-JET-CTI20 probe.
Note 1
Set the SW1-4 switches only when the emulator and the target are not powered!
Do not set SW1-2 and SW3-4 pairs both ON. The setting will short the EMU0, EMU1
and nSYSRTS lines on the target.
Note 2
Note 3
The nSYSRTS, EMU0 and EMU1 lines are bi-directional and are driven by an open-
collector gate in the emulator. EMU0 and EMU1 have 100K pull-ups to the PD pin on
the probe side, while nSYSRST has 220K pull-up to the PD pin.
Certain JTAGjet driver packages may not easily allow configuring EMU0 and EMU1 as
nSYSRST. Therefore it is recommended to leave the DIP switch in its default position.
The software is unable determine the position of this switch automatically. When SW2 or
SW4 are ON, the software needs to be configured accordingly. Sample settings that allow
EMU0 to act as a CPU reset signal (nSYSRST) are shown in Figure 34.
Note 4
FIGURE 34 Configuring the JTAGjet-eBinder driver to use
the EMU0 signal as the CPU reset signal (EmuDiag for the

All future releases of the JTAGjet software will allow the user to redefine the EMU0 and EMU1 pins as CPU
reset pins.

JTAG-ETM Splitter Probe
ADA-ETM-JTAG
A typical target board has both the JTAG signals and the ETM signals connected to the same standard 38-pin
ETM Mictor connector (see on p. 14). Some boards, however, separate the two types of signals, providing two
different connectors for them. These boards require a JTAG-ETM splitter probe, ADA-ETM-JTAG. This
probe is also useful when debugging an ARM or a DSP target board that does not have an ETM connector on
it.

JTAG cable is located at the bottom of the board.

Passive 20-pin Probe for Cortex ETM trace
ADA-ETM-SWD20
This passive probe provides an interface between the Signum JTAGjet-Trace emulator and the 20-pin high-
density connector on a Cortex target board. The pinout of the probe’s Cortex connector is the same as the
pinout of the ADA-ARM20-SWD probe’s 20-pin connector (Figure 41). The probe’s ETM connector has the
pinout of ETM connector when used with ARM targets (Figure 42).

Active 12-pin MPSD Probe
ADA-JET-MPSD
The Signum MPSD (modular port scan device) probe ADA-JET-MPSD provides a physical interface between
JTAGjet emulators for the TMS320 3x family of DSPs and target boards. The probe has 12 double-row,
polarized, 2.54 mm × 2.54 mm (.100" × .100") receptacles (female connectors). To ensure proper orientation,
the header is keyed. The ADA-JET-MPSD is a 5V Texas Instruments MPSD legacy adapter designed
specifically for the Signum JTAGjet-C3x in-circuit emulator. It allows emulation at a maximum speed of 60
MHz. For the pinout, see Figure 44.
