User Manual SERIALDIS Overview The SERIALDIS is a 6 digit LED display module which displays ASCII data sent to it via an RS232 or RS485 serial connection The device has addressing support so multiple devices can be driven whilst residing on a serial bus Being a 7 segment display it is not possible to display all alphanumeric characters so this display is primarily for numeric data Overview Requirements The module requires a serial input either RS232 or RS485 which supplies the data to display followed by a carriage return The baudrate is selectable from 9600 to 115200 but is fixed at 8 data bits 1 stop bit and no parity Configuration Configuration is by DIP switches where the baudrate and address can be set Operation The display accepts ASCII data and on receipt of a carriage return character decimal 13 hexadecimal OD the data will be displayed Physical Connections Single PC Connection Connect power to The Power In connector J4 Sul pl MOOD Connect to the serial bus using 5 OFF either J 1 or J 4 for RS232 or J 2 for RS485 Ji J2 J3 Rs232 O O O O 11007070 0 9 Way D Socket RS232 Pinouts CTS Tx Rx GND GND B GND GND GND RS232 RS485 POWER OUT POWER IN View from inside case 3 RX In 5 GND J 4 has been designed to enable a quick connection to a PC for testing by using a 9 way D cable extension pin to pin and connecting to the PC 9 way D socket Mantracourt Electr
