2. Remove the RF module (maintain the motherboard connection via flat ribbon cable).
Re-establishing the ground connection between RF module and motherboard:
Connect the M6 point on the component side of the RF PCB and the P4 point on the component side of the motherboard.
For this purpose, solder a stranded wire with a length of 10cm between the points M6 and P4.

4.5 Reading out / Changing of device data via infrared adaptor
4.5.1 Overview
You may read out and change data via the infrared adaptor. The Sennheiser service software supports the
following tasks you may want to perform:
• Reading out the current software version and, if necessary, carrying out of a software update (file "*.s19").
• Commissioning the receiver after a hardware replacement (e. g. replacing of a board).
• Changing the current frequency table.
• Changing / resetting the receivers's factory settings.
4.5.2 Required hardware
You will need the Sennheiser service package for reading in and out of device data
(“See “Special service tools” page 11.“):
For portable devices:
• Infrared adaptor for reading out / in data (e. g. SK 100 transmitter)
For stationary devices:
• RS232/RS485 converter with mains adaptor
• RS232 cable for connection of PC and converter
• RS485 cable for connection of receiver and converter
You may order the service package directly from Sennheiser:
Service package for ew G2 software, ID no. 094739, price group 161
4.5.3 Required software
You may download the service software free of charge from the Sennheiser homepage on the Internet.
In order for you to use the software, you will need the operating system Microsoft® Windows 98™ or higher
and a free COM port (RS232).
4.5.4 Information on the service software
Operating instructions for the service software are available in PDF format. These operating instructions
contain information on commissioning of the service package and reading out and in of device data.
After installation of the software, you will find the instruction manual in the Windows menu [Start].

4.5.5 Commissioning after replacing a board
After you have fitted a new board into the device, you have to write the new data (e. g. a new frequency table)
to the device.
Requirements
• You have replaced the defective board (e. g. the RF board of the transmitter/receiver),
• You have installed and launched the service software.
Writing of device data
Perform the following steps:
1. Put the infrared adaptor of the service set in front of the transmitter.
2. Connected the transmitter to the power supply (2.4V
3. Switch on the transmitter.
4. Start the service software
5. Click the [Auto Detect] button.
Result: Your connected device has been detected.
6. In the "Info" register, click the [EXECUTE ALL] button.
Result: All device data are read out. If all the data have been read out successfully, the message "Success"
is displayed.
Note: If you perform individual actions in the "Info" or "Service" registers, you have to return the device
into the operational status afterwards. For this reason, finally click the [Close Device] button.
7. Go to the "Service" register.
8. Click the [EXECUTE ALL] button.
Result: The new device data are written. If all the data have been written successfully, the message
"Success" is displayed.
DC
)
27
Result
You have successfully written the new data to the device. These new data now correspond to the
new factory settings for you device.
