Installation
The interface box operates from 115 VAC or 230 VAC power. Make sure that the power is
correct before connecting to a power supply. A green power LED is illuminated when the box is
plugged into the power source.
Two cables are supplied with the model 29122 interface box:
• A model 32511 cable for connection between the 3650EX instrument LEMO-6 connector and
the interface box
• A model 32538 cable for connection between the interface box and the PC.
The connections should be made as indicated in Figure 3 .
Note: When the Interface Box is connected to the 3650Ex instrument, this also acts as a power supply to
the instrument and disconnects the internal battery power source.
Note: If you use an adapter for the connection to the PC, make sure it is designed for this purpose and,
thus, has all nine pins accessible. Some 25-to-9 pin adapters are supplied for specific use, such as a
mouse, and these may have only certain pins available.
