Summary

The AVer CL01 is a camera controller that issues VISCA commands to AVer PTZ cameras via VISCA over IP (UDP, port 52381) and RS-232 serial. This spec covers only the five concrete command examples the source documents as literal byte sequences: Power Off, Power On, Camera Menu (OSD toggle), Pan-Tilt Up, and Pan-Tilt Stop. The source is a generic app-note and does not constitute a full VISCA command reference.

Transport

protocols:
  - udp
  - serial
addressing:
  port: 52381  # VISCA Control port, UDP, IPv4 - stated in source
auth:
  type: none  # inferred: no auth procedure in source
serial:
  baud_rate: 9600  # stated in source ("Baude Rate: 9600, to start with")
  data_bits: 8  # UNRESOLVED: data bits not stated in source; 8N1 is VISCA convention but not confirmed
  parity: none  # UNRESOLVED: parity not stated in source
  stop_bits: 1  # UNRESOLVED: stop bits not stated in source
  flow_control: none  # UNRESOLVED: flow control not stated in source

Traits

- powerable   # inferred from power on/off command examples

Actions

# Wire format note: For VISCA over IP (UDP), each command is a full packet:
# 4-byte header (01 00 00 LL) + 4-byte sequence number (00 00 00 00) + VISCA payload.
# LL is the VISCA payload length in hex. The source shows identical byte sequences
# for both "Visca over IP" and "RS-232" sections - for RS-232 VISCA serial the
# packet header bytes are omitted and only the VISCA payload (81 ... FF) is sent.
# The source does not explicitly restate RS-232-only byte sequences for PT_Up/PT_Stop.

      After any pan-tilt movement command (e.g. PT_Up), a PT_Stop command must be sent
      to halt movement. Source states this explicitly.

Notes

The source is a generic AVer Pro-AV VISCA app-note, not a CL01-specific command reference. The CL01 RS-232 pinout (9-pin DSub-M: Pin 2 RXD, Pin 3 TXD, Pin 5 GND/Shield) is documented. The app-note covers multiple camera models (PTZ310, PTZ330, TR311, TR331, TR333, TR530, TR320, TR311HN, TR313); the CL01 is identified as the controller issuing these commands. VISCA packet header bytes 3–4 encode the VISCA payload length (e.g. 00 09 = 9 bytes payload). The sequence number field (bytes 5–8) is shown as 00 00 00 00 in all examples. RS-232 protocol supports VISCA (up to 7 cameras), Pelco-P (up to 32), and Pelco-D (up to 256); this spec covers VISCA only.
