SCPI Programming Mode
SCPI commands are ASCII text strings with a wide array of defined SCPI commands, all of
which are not included in this implementation. The SCPI protocol is only available over Ethernet
port 5025. The only available SCPI commands for the F4T are shown below. This complete list
is only valid for Firmware Revision 04:05:0007, released May 23, 2019 and higher. Older
firmware versions do not include all these commands. This list only applies to the native F4T
Ethernet interface, NOT the external Serial Modbus-to-Ethernet Converter.
