Summary: This blockset allows Simulink to communicate with remote devices using RS232 interface Description: RS232 Blockset is a block library that allows to a simulation model to communicate directly and in real time (using, for example, the RT Blockset also published in Matlab Central) with a remote device. The right temperature monitoring system should allow you to keep track of critical temperatures at all of your sites, server rooms, and data centers that contain important gear. RS232_Read_Binary_Buffer: This block reads bytes from the serial port, add them to the input buffer and gets, starting at the start of the buffer, formatted data (the format is declared in the format string argument), leaving into the buffer all the bytes that exceeds the read operation. To set the power supply in external programming mode on either the front panel or RIS panel, using the following steps: Magna-Power Electronics' prodcuts use Standard Commands for Programmable Instrumentation (SCPI commands) over RS232 for intuitive control over the power supply.
