Summary

The VIO 4K (Ref. V701, firmware v02.00.7X) is a 4K multilayer image processor / seamless switcher controllable via the TPP (Third Party Protocol) register-based interface over TCP/IP (default port 10600), RS-232, and HTTP (live snapshot retrieval). This spec covers the TPP command set documented in the official TPP Programmer's Guide: connection handling, power/standby/reboot control, preset and view recall, layer source routing, test patterns, and live snapshot URLs.

Transport

protocols:
  - tcp
  - serial
  - http
# --- TCP (primary control: TPP) ---
addressing:
  port: 10600  # default TPP port, stated in source
  base_url: "http://<machine_ip>"  # used for HTTP snapshot retrieval; IP via DHCP (client: yes)
# HTTP snapshot port not stated in source
# port (http): null  # UNRESOLVED: http port not stated in source (do not assume 80)
# --- RS-232 (secondary control) ---
serial:
  baud_rate: null  # UNRESOLVED: source states range 1200-115200 baud, no single default; configurable via front panel / Web RCS
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
# --- Auth ---
auth:
  type: none  # inferred: no auth procedure in source
# Notes:
# - Ethernet RJ45, 10/100 Mbps, auto-MDIX.
# - TCP TPP server accepts at most 5 clients simultaneously.
# - DHCP client enabled by default.
# - All TPP commands are displayable ASCII (0x21-0x7E) terminated with LF (0x0A).
# - Device answers end with CR LF (0x0D 0x0A).

Traits

- powerable   # inferred: power off / standby / wake / reboot commands present (SBreq, SBreb)
- queryable   # inferred: read commands return register values (DEV, TPver, TPcon, #, etc.)
- routable    # inferred: layer source change + preset/view recall commands present (PRinp, PKrcr, PBrcr, PBirr)

Actions

# All commands terminated with LF (0x0A). Device answers end with CR LF (0x0D 0x0A).
# Write command = [indexes,] value, registername ; Read command = [indexes,] registername (value omitted).

Safety

confirmation_required_for:
  - power_off        # requires manual restart after shutdown
  - reboot_device    # restarts the device
  - standby          # blanks output until wake_up
interlocks:
  - "RS-232 enabled alongside low baud rate slows down device operations (source warning §2.2)."
  - "Manual commutation mode with multiple controllers causes unpredictable results / command intermixing (source warning §3.4). Use a single controller in manual mode."
  - "Live snapshot request rate must not exceed 1 per second (source §3.9)."
  - "TPP server limited to 5 simultaneous TCP clients (source §2.3)."
# No hardware interlock / power-on sequencing procedure stated in source beyond the above warnings.

Notes

  • TPP = Third Party Protocol. The device is a register-based state machine: writing registers changes state, reading registers reports current state. Write and read share one syntax; a write is distinguished only by the presence of a value before the register name.
  • Command grammar: [idx1,[idx2,[idx3,]]][value,]REGNAME LF. Register names are ≤5 letters (3 single-letter exceptions, e.g. #/DIESE). Reads omit the value field. Index counts range 0–3 depending on register.
  • Answers mirror the command: REGNAME[idx,][value] CR LF. Errors: E10 register-name error, E11 index out of range, E12 wrong index count, E13 value out of range — each terminated with CR LF.
  • Command processing is asynchronous; answer delay is not constant/predictable, but multiple commands may be sent in advance. Best practice: check acknowledgements before sending the next command block.
  • String values are quoted ("..."); embedded quotes escaped as \", literal backslash as \\.
  • Descriptive register names referenced in §3.4 map to TPP mnemonics: PE_INPUTNUM → PRinp, PRESET_BANK_RECALL_REQUEST → PKrcr, PRESET_VIEW_BANK_RECALL_REQUEST → PBrcr, PRESET_VIEW_BANK_ACTIVE_RECALL_REQUEST → PBirr.
  • Index ranges: preset banks 0–15; view banks 0–63; screens/outputs 0–5; inputs 0–8; pattern keys 1–15.
