5. Connections
5.1. Cable Recommendations
The Mag648 and Mag649™ electronics board provides balanced output lines for analogue signal
transmission. Suitable shielded cables can be supplied.
Cables are particularly prone to wear and damage if twisted, flexed beyond their design limits, or
subjected to excessive or repeated movement. All cables should be mounted securely in place.
When designing their own cable, the following recommendation should be followed:
• ensure that the cables are shielded to prevent them picking up electromagnetic
interference.
• the cable shield should be connected to power supply ground at the power supply end
(either through the connector body, or by connecting the shield to the power ground
wire).
5.2. Connection to Power Supply/Acquisition Unit
Caution:
When providing your own power supply, do not exceed the voltage rating, provide
sufficient current, and ensure correct polarity is respected see DS2298.
