MJ-134
MJ-134 is meant for component level troubleshooting.
The jig includes an RF interface for GSM and Bluetooth. In addition, it
has the following features:
• Provides mechanical interface with the engine module
• Provides galvanic connection to all needed test pads in module
• For GSM 850, GSM 900, GSM 1800 and GSM 1900 bands, use CA-128RS
cable connected to right angle mouth SMA connector on fixture.
• Use losses for CA-128RS cable for correct attenuation values for
accurate testing and calibration. For GPS (1485 MHz) band, use
CA-128RS with XRS-6 RF cables. CA-128RS connects to jack X6201
located component side top of module. Add losses for CA-128RS RF
cable to losses for XRS-6 RF cable for correct attenuation values for
accurate testing and calibration. For Bluetooth (2500 MHz) band,
use instructions for SB -6 (or JBT-9).
• Multiplexing between USB and FBUS media, controlled by Vusb
• MMC interface
• Duplicated SIM connector
• Connector for control unit
• Access for AV- and USB connectors
For RF attenuation values, see
(page 2–16).

PK-1
PK-1 is a hardware protection key with a USB interface. It has the same
functionality as the PKD-1 series dongle.
PK-1 is meant for use with a PC that does not have a series interface.
To use this USB dongle for security service functions please register
the dongle in the same way as the PKD-1 series dongle.

SW security device is a piece of hardware enabling the use of the
service software when connected to the parallel (LPT) port of the PC.
Without the device, it is not possible to use the service software.
Printer or any such device can be connected to the PC through the
