The following conditions apply for an RS-485 bus system:

–A bus system consists of a bus line and/or one or more branch lines.

–Cable lengths exceeding 100m or 300ft must be installed as bus lines.

–Branch lines are branching connections from a bus line.

–Peripheral devices are AMC2 4W which are connected to the host computer.

–Maximum cable length of a bus line must not exceed 1200m or 4000ft.

–The cable length of branch lines must not exceed 100m or 300ft.

–Any bus line conductor connects up to eight AMC2 4W. The maximum number of devices must not be exceeded.

–For longer bus lines connect the AMC2 4W to multiple AMC-MUX (-EXT) with the host.

NOTE!

Up to seven AMC-MUX-EXT can be connected to an AMC-MUX.

i Every module subjects the conditions above. Using the exten- sions you can’t connect more than eight AMC2 4W.

To get more information about the AMC-MUX and the extension see the manual of these devices (F.01U.012.855).

To use RS-485 mode at the AMC2 4W, connect the data cables to the pluggable screw connector of the RS-485 host interface. Set the connection mode of the RS-485 using the DIL switch of the AMC-MUX. Then set the RS-485 address via DIL switch or software and activate the RS-485 two-wire or four-wire mode via jumper settings on the AMC - see Figure 5.10 and

Figure 5.12.
