Electrical Installation - Field and Host Port Connections Direct connection can only be made if the CIU 888 and the DTE (CIU 888 or host computer system) are grounded at the same point. In all other cases, ensure there is at least a proper galvanic isolation at the DTE side.
Ports are not galvanically isolated. 3.6 Ethernet Ports CIU 888 has 6 Ethernet ports, one on front side and 5 on rear side of CIU 888. All ports are 10/100 Mbps compliant and support Auto MDIX support (auto detects Straight or Cross cable and switches accordingly).
Electrical Installation - USB Ports 3.7 USB Ports CIU 888 has 3 USB ports, one on the front side and two on the rear side. Back ports are designed to interface with keyboard and mouse. These are low power devices and require currents less than 100 mA for normal operation.
Shield: Signal Ground 3.11 Relay or DO Outputs [Part of a future release] CIU 888 has two relay outputs. They are also called digital outputs (as they offer make or break connections). Refer to port details chapter for locating this connector.
