Nov 03 2020 | SE-500MU

The SE-500MU supports RS-232 serial control but sometimes there is some confusion on how to setup the command strings.  We placed some command string examples and additional information required to setup serial control with the SE-500MU.



RS-323 PINOUTS
Let’s start with the serial pin definition on the SE-500MU for RS-232:
The 9 pin D-SUB connector has the following pinouts:

There are 4 pins for GND (Pin 1, 5, 6, 9), it is ok to connect Pin 5 only for ground.
 
    Pin 1 : GND
    Pin 2 : TXD *
    Pin 3 : RXD *
    Pin 4 : N/C
    Pin 5 : GND *
    Pin 6 : GND
    Pin 7 : N/C
    Pin 8 : N/C
    Pin 9 : GND
