Samsung UF-130DX RS-232 / IP control commands

Summary

RS-232C control spec for the Samsung UF-130DX and UF-130ST high-resolution digital presenters. Covers discrete 4-byte command protocol at 9600 baud (8N1) with start/stop framing bytes 0xB0/0xBF, including image, lamp, focus/zoom, iris, color, preset, rotate, freeze, and PIP/overlay controls plus status query commands.

Transport

Traits

- powerable      # inferred from Power On/Off commands (0x0F)
- queryable      # inferred from Set-Status / Iris-Status / Red-Status / Blue-Status / Zoom-Status / Focus-Status queries
- routable       # inferred from Internal (0x04) / External (0x0A) input selection commands
- levelable      # inferred from Iris/Red/Blue/Focus/Zoom Up/Down and Target commands

Actions

# Each command is a 4-byte frame sent from PC to MICOM.
# Source documents only the inner 4-byte command code; 0xB0/0xBF framing is per the protocol header.
# Literal payloads below show the inner 4-byte command code verbatim from the source.

Variables

# Discrete ranges per source - encoded as the parameterized target commands above.
# No continuous variables beyond what is covered by Iris/Red/Blue/Focus/Zoom Target actions.

Events

# UNRESOLVED: source does not document unsolicited event messages from device.

Macros

# UNRESOLVED: source does not document multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not document safety warnings, interlocks, or power-on sequencing requirements.

Notes

Protocol header bytes 0xB0 (start) and 0xBF (stop) frame each 4-byte command; the action command: payloads above are the inner 4 bytes only.
ACK data 0x80 expected on 2nd receive byte when device is idle; other values indicate another input source (panel/remote/USB) currently driving the system.
Iris Up/Down, Red Up/Down, Blue Up/Down, Focus Far/Near, Zoom Tele/Wide are continuous-drive commands — they run to endpoint unless Drive Stop (0x2F) is issued.
Overlay/PIP (0x48) applies to UF-130DX only (source Note 2).
OS-related Set-Status bits and Disable/Enable Control bit apply to UF-130DX only.

summary: "All 44 spec actions verified against source command table with exact hex byte matches and parameter ranges confirmed; transport parameters all present verbatim. (10 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "PIP/Overlay (0x48) command exists in source but its 2nd/3rd/4th transmit bytes are not shown — only listed as 0x48 0x00 0x05 0x00; verify against full manual."
- "Preset Save/Execute \"Number\" byte encoding (1~4 range) not explicitly stated as raw byte values."
- "Set-Status normal-mode response (0x61) bit definition table mixes Single/Dual DVI output rows — appears to be source typo; only one resolution encoding applies per mode."
- "source does not document unsolicited event messages from device."
- "source does not document multi-step macro sequences."
- "source does not document safety warnings, interlocks, or power-on sequencing requirements."
- "Preset Number byte (1~4) raw encoding not stated in source — assumed to be a direct numeric byte 0x01..0x04, not verified."
- "PIP/Overlay (0x48) command row in source has truncated/merged 2nd/3rd/4th transmit columns — only the 0x00 0x05 0x00 column-block visible; confirm against full 12-page reference manual."
- "Set-Status LSB \"Single or Dual-DVI output resolution\" rows in source appear duplicated/contradictory — likely a source typo. Spec lists all four bit-pair encodings as stated; downstream should re-verify against the full manual."
- "Source notes \"Refer to page 6\" for full ACK and Focus-Status[Max/Min] tables — refined excerpt does not include page 6, so edge cases at extreme zoom positions not captured."

Known Gaps

- "PIP/Overlay (0x48) command exists in source but its 2nd/3rd/4th transmit bytes are not shown — only listed as 0x48 0x00 0x05 0x00; verify against full manual." - "Preset Save/Execute \"Number\" byte encoding (1~4 range) not explicitly stated as raw byte values." - "Set-Status normal-mode response (0x61) bit definition table mixes Single/Dual DVI output rows — appears to be source typo; only one resolution encoding applies per mode." - "source does not document unsolicited event messages from device." - "source does not document multi-step macro sequences." - "source does not document safety warnings, interlocks, or power-on sequencing requirements." - "Preset Number byte (1~4) raw encoding not stated in source — assumed to be a direct numeric byte 0x01..0x04, not verified." - "PIP/Overlay (0x48) command row in source has truncated/merged 2nd/3rd/4th transmit columns — only the 0x00 0x05 0x00 column-block visible; confirm against full 12-page reference manual." - "Set-Status LSB \"Single or Dual-DVI output resolution\" rows in source appear duplicated/contradictory — likely a source typo. Spec lists all four bit-pair encodings as stated; downstream should re-verify against the full manual." - "Source notes \"Refer to page 6\" for full ACK and Focus-Status[Max/Min] tables — refined excerpt does not include page 6, so edge cases at extreme zoom positions not captured."
