144 RabbitCore RCM3365/RCM3375Use a straight-through Ethernet cable to connect the master to slave peripheral cards, unlessyou are using a device such as the OP7200 that could be used either as a master or a slave. Inthis case you would use a crossover cable to connect an OP7200 that is being used as a slave.Distances between a master unit and peripheral cards can be up to 10 m or 33 ft.F.1.2 RabbitNet Peripheral Cards• Digital I/O24 inputs, 16 push/pull outputs, 4 channels of 10-bit A/D conversion with ranges of0 to 10 V, 0 to 1 V, and -0.25 to +0.25 V. The following connectors are used:Signal = 0.1" friction-lock connectorsPower = 0.156" friction-lock connectorsRabbitNet = RJ-45 connector• A/D converter8 channels of programmable-gain 12-bit A/D conversion, configurable as current mea-surement and differential-input pairs. 2.5 V reference voltage is available on the con-nector.
