2. Hardware Implementation of the LUFP7 Gateway

2) Cables:
ƒ VW3 A8 306 R•• Modbus cable	Shielded cable with a male RJ45 connector at each
(“star” topology / “bus” topology with tap boxes)	end.
ƒ VW3 A68 306 Modbus cable	Shielded cable with a male RJ45 connector and a
(“bus” topology with tap boxes)	male 15 point SUB-D connector. It is used to connect
	a Modbus subscriber (slave or master) to a
	TSXSCA62 or TSXCA50 box.
ƒ Shielded double twisted pair Modbus cable	Bare cable (without connectors) used to make up the
(“bus” topology with branch boxes)	main section of the Modbus network. There are three
	items available: TSXCSA100 (100 m), TSXCSA200
	(200 m), and TSXCSA500 (500 m).
