5. TUUU DATA LOGGER MANUAL The ML 215 315 except the ML x15AD comes with one RS 232 port which is shared with SDI 12 or RS 485 RS232 is a widely spread interface standard which uses 3 wires minimum for data communication It is a so called asymmetric interface that uses one wire for Tx one for Rx and one for ground It is called asymmetrical because it uses only one wire per signal Therefore it s susceptible for interference and hence the maximum cable length is limited to 15meters Please keep in mind these limitation when you design your system RS232 is not a bus system and therefore it is only allowed for one device to be connected to a RS232 port So the maximum number of serial devices to connect to your ML 2012 13 is 2 RS232 sensors should be connected to the data logger with their signals crossed That is Rx Tx We strongly recommend using RS485 instead of RS232 when cable length exceeds the 15m 4 4 RS485 RS485 is a serial bus system which uses 3 wires for its communication It uses a differential balanced line which can span relatively large distances up to 4000 feet 1200 m A rule of thumb is that the speed in bit s multiplied by the length in meters should not exceed 10 Thus a 50 meter cable should not signal faster than 2 Mbit s Instead of RS232 RS485 is capable of communicating with more than one device After all it is a bus system RS485 sensors are called slaves and must have their uniq
