ALTERNATIVE CONNECTIONS FOR ETHERNET MODELS139BON-BOARD ETHERNET CONNECTORA Standard M12 D-Coded female connector is provided for the on-board Ethernetconnection. This interface is IEEE 802.3 10 BaseT and IEEE 802.3u 100 BaseTx compliant.Use Cat 5e or superior cables.Figure 82 - M12 D-Coded Female Ethernet Network ConnectorOn-Board Ethernet Network Connector PinoutPin Name Function1 TX + Transmitted data (+)2 RX + Received data (+)3 TX - Transmitted data (-)4 RX - Received data (-)ID-NET NETWORK TERMINATIONThe network must be properly terminated by a 120 Ohm resistor at the first and last reader ofthe network.INPUTSThere are two optocoupled polarity insensitive inputs available on the M12 17-pin connectorof the reader: Input 1 (External Trigger) and Input 2, a generic input.The electrical features of both inputs are:V AB Max. I IN Max.30 V 12 mAThe relative pins on the M12 17-pin connector are:Pin Name Function1 Vdc Power Supply input voltage +6 I1A External Trigger A (polarity insensitive)5 I1B External Trigger B (polarity insensitive)13 I2A Input 2 A (polarity insensitive)3 I2B Input 2 B (polarity insensitive)2 GND Power Supply input voltage -3412
