[Connection]

Use 2 twisted pair cables with a modular jack fitted at each one end to connect the AI-MS900 to the AI-900MS. Refer to the following table for the maximum recommended cable length between the two.

Cable type	AWG24 (0.52 mm)	AWG22 (0.65 mm)	AWG20 (0.82 mm)
Distance	0.9 km	1.5 km	2.3 km

Connect as shown below.
