- VBS-HDIP-718WP4: 4-gang, HDMI and VGA in, Line-In, Micro USB, Source Dipswitch, POE network, Mic-In, HDMI out, Stereo out, RS232 with null modem
Settings are startup functions that load as the unit is powering on. In order for Settings to be applied, they must be saved and the unit must be rebooted.
Commands are active functions that have immediate effect on behavior. Many Commands will also apply a Setting to ensure that the behavior persists through a reboot.
Access
All Settings should be entered via the Command Line Interface accessible via:
- Telnet to the IP of the unit, at port 23
All Settings are case-sensitive.

Chaining Settings
Multiple settings can be chained together to be applied simultaneously. Separate each command with a semicolon (;). Recommend adding Delay 1 Second after Save to ensure that the device has time needed to commit changes to permanent memory.
