Note
Maximum cable length allowed for USB connection is 3 m. If longer cables are used, special
overvoltage and filtering elements must be installed to comply with the requirements of EMI/RFI
CE

certification. Only use high quality industrial USB devices with sufficient EMI compatibility.
Use shielded cables for maximum EMI protection.
Drawing excessively power might disturb operation.

Ethernet LAN Interface
The PROTOUCH-WIDE-R features up to two PCI Ethernet controllers having assigned the base address and IRQ at boot time by the BIOS. The
Ethernet interface drives two LED’s (yellow and green) beside the LAN connector for status information. The meaning of the LE
D activity is
programmable (normally set by the low-level driver).
LAN1 and LAN2 feature Intel I210 Ethernet controllers supporting 10/100Mb/s. Both interfaces support Auto Negotiation and Auto MDIX
functions. Check manufacturer’s datasheets for detailed information.
No configuration options are available for the Ethernet device.
Device Connection
The Ethernet interfaces use the standard D-coded M12 CAT5 connector LAN1 and LAN2 on the front for 100
shielded
Twisted Pair cabling.
Mating connector type for LAN1, LAN2: any standard D-coded male M12 CAT5 conformal connector.
