Motionet™ MN85
RS232 to RS485 Converter

FEATURES: Converts Standard RS232 signals to RS485 Multidrop network Drives up to 127 devices Convenient screw terminal hookup Includes 9 VDC power adaptor Plugs directly into PC com port

The MN85 is an RS232 to RS485 converter used to connect multiple Motionet devices to a standard com port on MSDOS/Windows PC's. The device allows up to 127 devices to be connected to a single port. Only two wires are required for communications. If connecting more than one device, you can daisy chain the devices. Connect (+) terminal on MN85 to (+) on MN100 and (-) terminal on MN85 to (-) on MN100. The RS485 network requires that the two extreme ends of the cables be terminated with a 120 ohm resistor. This terminating resistor is built into the MN85. Make sure you have resistors installed only at each end of the network.
