The table below gives a short overview of service devices that can be used for testing, error analysis, and
repair of product RM-609. For the correct use of the service devices, and the best effort of workbench setup,
please refer to various concepts.
Issue 1
MJ-300
Module jig MJ-300 is designed for regional Central Services for engine
testing. It can be used for flashing via USB and RF, battery and system
testing.
The main functions are:
• Powering with external power
• CU-4 interface adapter to phone (requires SS-227)
• WLAN/BT/GPS RF-interfaces with probes
• GSM/WCDMA RF-interfaces with probes
• BSI mode selector (Tabby and Lynx interface, selected with battery
cable)
• VBATT interface (Tabby and Lynx interface, selected with battery
cable)
• CA-128RS cable is used together with this jig for RF testing
VBATT functions can be performed in the CU-4 (requires SS-227).
Calibration voltages and currents e.g. are protected and monitored by
the CU-4 interface software (protection for over-current, overvoltage
and reverse voltage).
VBATT can be powered through MJ-300 (SS-227 not required) with
external power. MJ-300 provides the VBATT with SMPS regulation to
3.9V/2A and regulation bypass with overvoltage protection (trip point
~4.4VDC). The VBATT external supply is provided with overvoltage
protection (trip point ~16.5VDC), polarity protection and over-current
protection (fuse 2.5A slow).
SS-227
SS-227 is designed for regional Central Services to be able to use CU-4
with MJ-300 module jig. With SS-227, CU-4 can be used for battery
testing.
The main functions of SS-227 are:
• CU-4 interface adapter to MJ-300
• BSI mode selector (Lynx and Tabby mode selection)
• VBATT interface
All functions are performed in the CU-4. Calibration voltages and
currents e.g. are protected and monitored by the CU-4 interface
software (protection for over-current, overvoltage and reverse
voltage).
