2. Installing ACP Connecting Ethernet cable to ACP After connecting the ACP and the RS485 cable, the Ethernet cable should be connected to the ACP. The ACP can be connected to the hub via the Ethernent cable or directly to the AC Manager. Connecting the ACP and the hub The ACP is connected to the basic Internet network installed at the field, generally to the hub. In this case, the Ethernet cable should be connected by the direct cable. Use the Ethernet cable (direct cable) to connect to the Ethernet 1 port of the ACP. Connecting the ACP and the AC Manager It is the case installing the AC Manager to the separate PC and directly connecting the ACP to the PC. In this case, the Ethernet cable should be connected by the cross cable. Use the Ethernet cable (cross cable) to connect to the Ethernet 1 port of the ACP. Caution: Ethernet cable type It should be identified whether the Ethernet cable to be connected is the direct cable or the cross cable. Also, connect the cable by using the LAN tester to check whether the cable has any problem. For more information about the direct cable and the cross cable, see Chapter 4.
