EPM-3032: Driver Installation
The EPM-3032 may be accessed through the Linux console as a tty device node. The Moxa driver creates a
special device node that is identified as a
ttyM* device. The EPM-3032 device nodes are listed as /dev/ttyM0
and
/dev/ttyM1, or alternately as /dev/ttyM8 and /dev/ttyM9. The UART API allows you to configure
these device nodes for RS-232, RS-422, 4-wire RS-485, or 2-wire RS-485.
Upload the driver and tool packages to
/dev/shm, a temporary file system on your computer.
root@Moxa:~# scp v2400a-mxser_1.0.0_amd64.deb moxa@192.168.3.127:/dev/shm
