Roland V-1HD+ RS-232 / IP control commands

Summary

The Roland V-1HD+ is a 4-input HDMI video switcher/mixer with integrated audio mixing, picture-in-picture (PinP), split, and downstream key (DSK) compositing. This spec covers remote control via the RS-232 interface using ASCII command strings. The unit also exposes a USB port for remote control and a DB-9 TALLY connector for program/preview tally output.

Transport

protocols:
  - serial
serial:
  baud_rate: 38400  # configurable: 38400 or 115200 (RATE menu). Source states both; no single default value identified.
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: xon_xoff  # source: "Flow control XON/XOFF"; XON=11H, XOFF=13H
auth:
  type: none  # inferred: no auth procedure in source
# Command framing: STX (02H) + 3-char command code + ":param,param" + ";"
# Acknowledgement: ack (06H) returned for accepted commands.
# Verify ack before sending next command.

Traits

traits:
  - routable    # inferred: video input/output source selection (IPS, OH1, OH2, PGM, PST)
  - queryable   # inferred: status queries present (QAL, QPL, TLY, VER, ACS)
  - levelable   # inferred: volume, gain, position, key-level numeric adjustments

Actions

# Framing note: every command is prefixed with STX (ASCII 02H) and terminated with ";".
# The `command:` field shows the verbatim sent-command string as written in the source,
# with STX represented as "stx" per source notation. Parameters are substituted into
# the {a},{b} placeholders. Accepted commands return "ack" (ASCII 06H).

Macros

# No multi-step sequences explicitly described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no safety warnings, interlock procedures, or power-on sequencing
# requirements stated in this source excerpt. Tally output is open-collector,
# max 12 V / 200 mA per the TALLY connector specification (informational, not an interlock).

Notes

RS-232 must be enabled: press [MENU] → "TALLY/RS-232" → set "RS-232" to "ON".
TALLY output must be enabled separately via the same menu ("TALLY" → "ON").
Use an RS-232 crossover cable between unit and controller. Pins 4-6 and 7-8 are cross-connected inside the unit.
RS-232 connector: DB-9 male. TALLY connector: DB-9 female (open-collector tally, pins 2-5 = PGM/A [1]-[4], pins 6-9 = PST/B [1]-[4], pin 1 = GND).
Command framing: STX (02H) + 3-char command code + optional ":param,param" + ";". All ASCII.
After each command, wait for ack (06H) before sending the next.
RATE menu offers 38400 or 115200 bps; the controlling device must match the configured rate.

Macros

# No multi-step sequences explicitly described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no safety warnings, interlock procedures, or power-on sequencing
# requirements stated in this source excerpt. Tally output is open-collector,
# max 12 V / 200 mA per the TALLY connector specification (informational, not an interlock).

Notes

RS-232 must be enabled: press [MENU] → "TALLY/RS-232" → set "RS-232" to "ON".
TALLY output must be enabled separately via the same menu ("TALLY" → "ON").
Use an RS-232 crossover cable between unit and controller. Pins 4-6 and 7-8 are cross-connected inside the unit.
RS-232 connector: DB-9 male. TALLY connector: DB-9 female (open-collector tally, pins 2-5 = PGM/A [1]-[4], pins 6-9 = PST/B [1]-[4], pin 1 = GND).
Command framing: STX (02H) + 3-char command code + optional ":param,param" + ";". All ASCII.
After each command, wait for ack (06H) before sending the next.
RATE menu offers 38400 or 115200 bps; the controlling device must match the configured rate.
