The Hall Research VERSA-4K receiver is an AV-over-IP decoder that renders 4K HDMI video, USB 2.0, keyboard and mouse, IR, RS-232 and analog audio from a sender on the same gigabit network. It outputs up to 4K at 30Hz 4:4:4, includes a scaler, an on-screen display generator and a video-wall processor for arrays up to 16x16 with bezel compensation and rotation, and provides four USB ports.
Resolution: Up to 3840x2160 at 30Hz 4:4:4, HDCP 2.2 and 1.4
Type: ASPEED AV-over-IP endpoint, multicast group routing
Inputs: Network only; 1x HDMI output, 4x USB, RS-232, IR, analog audio
Mounting: Surface or rack with the optional shelf
First Use: Put the device on the same subnet as the controller and connect to TCP port 9999. The device answers with a greeting line and a '> ' prompt; consume both before sending a command. The greeting carries the API version, for example 'VERSA-4K Telnet Server V1.2' - read it to learn which command set this firmware supports, because later firmware adds commands that V1.2 rejects as Invalid Command!. There is no authentication. The device takes a DHCP address by default and at most four clients may connect at once.
Video Optimization: Enable jumbo frames at 8000 on the device and on every switch port in the path; SET MTU requires a reboot. The network must have IGMP snooping enabled with a querier, because all streams are multicast.
CEC: Not available on API V1.2. Later firmware adds a CEC send command; read the greeting to determine whether it is present.
Switch: A switch is a multicast group change, not a crosspoint. Send SET CHANNEL with %v set to the group number the wanted sender is publishing on, then confirm with GET GROUP. Senders and receivers on the same number are connected. The firmware derives the multicast address from the group number, so nothing needs to assign one: group 11 becomes 225.2.0.11.

Power Cycle: Remove PoE or the local power supply for ten seconds, or send RESTART DEVICE over the telnet API. The session drops and the device restarts.
Factory Reset: Send FACTORY RESET over the telnet API, or use the front-panel reset. This clears the device name, group and network settings.
