4. DINplayer withstands serial communication in 4 different modes with the RS485 electrical standard This type of serial multipoint communication consents the connection in bus of up to 32 devices with a maximum distance of 50 metres The DINplayer devices connected to the RS485 bus can not autonomously begin communication but they can only respond to a specific request command from the master station usually a PLC or a computer The RS485 connection parameters speed parity check sum etc are set via the configuration file config txt A IMPORTANT e The internal electronics of DINplayer are not galvanically insulated from the RS485 line in case of short circuit or discharge to ground it is possible to damage not only the DINplayer but even the master system to which it is connected e For the RS485 connection one must remember to ignore the transmission echo from the master that is returning through the serial line 8 1 DINplayer and RS485 To enable the serial port through the 11 485A and 12 485B pins raise the cover of the device and move the P1 and P2 jumpers of the diagram as indicated in the following figure With the RS485 connection one must supply termination resistors on both extremes of the line to avoid the generation of stationary waves and to define the impedance of the lines even in absence of transmission DINplayer already has within itself a termination resistor enabled through a JP1 bridge jumper to enable
