Equipment Installation
The connectors are laid out as follows:
The connector for the 9V dc is a 6/6 modular plug, whilst the connector for
the RS232 is an 8/8 modular plug. The other connectors are fast
connectors. Release of the internal spring can be achieved by either
pushing a 0,5 mm or similar small probe into hole 1 or 2 while pushing the
stripped wire into hole 3. Check that the wire is secured by pulling the wire
gently.
