RS485 are available comms for both SGD 43-A and SGD 70-A. The software currently supports ASCII based serial communication as well as the MODBUS (RTU) protocol with more protocols planned for release later in the year. Lascar’s 7” display, the SGD 70-A, already accommodates RS485 comms with no additional hardware required. For users of the 4.3” display, the SGD 43-A, an additional add-on board (S43-RS485) is required. Other features of the new Design Studio Software include project file password protection, improved data logging features and trend graphing, string builder and PWM frequency control. All are available through Praxas.
