net (TCP/IP) interface. Additionally, a touch sensitive display can be used for manual switch control.

selecting an input allows choosing either output or "OFF", selecting an input allows choosing any of

2.2 Operation using SCPI commands
Section 4 details all SCPI commands. The commands »:OUT«, »:OUTA« and »:OUTB« are used to
connect both or a single output to any of the twelve inputs. The commands expect the input number,
between one and twelve as parameters. Specifying zero will turn the respective output off.
The »:CNT?« command can be used to check the number of switching cycles for each RF relay.
