Summary

The DIDO Jr. is an Aurora Multimedia video-wall / multi-window image processor and scaler (DVI/RGB/S-Video inputs, scaled DVI/RGB output). This spec covers its RS-232 control protocol (also carried over RS-485 for unit chaining). The device is addressable (000–254, with 255/*** as broadcast) so multiple units can share one serial bus. Commands use an ASCII !/?/~ prefixed format terminated by <CR> (0x0D).

Transport

protocols:
  - serial
serial:
  baud_rate: 115200      # source: "115k 8N1 (Default)"; selectable 2400-115k
  baud_rate_selectable: UNRESOLVED  # source states only the range 2400-115k, not the discrete steps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: UNRESOLVED  # flow control not explicitly stated by "8N1"
  connector: "9-pin to 6-pin mini-DIN RS-232 NULL cable (manufacturer-supplied)"
  pinout_rs232:
    1: Ground
    3: TX
    5: RX
  pinout_rs485:          # used for looping multiple units
    1: Ground
    4: "485+"
    6: "485-"
auth:
  type: UNRESOLVED  # source does not state this (was inferred none: no login/password/auth procedure in source)

Command format (verbatim from source): [Prefix][Address][Command][n][m][<CR>]

  • Prefix: ! = command, ? = query, ~ = response
  • Address: 3 ASCII digits 000–254, or *** / 255 for broadcast
  • <CR> = 0x0D (decimal 13)
  • Responses are always UPPERCASE; commands/queries are not case-sensitive.
  • {addr} in command templates below = the 3-digit target unit address (or *** for broadcast).

Traits

traits:
  - powerable    # inferred: POWERON / POWEROFF / KEY_POWER commands present
  - routable     # inferred: WINDOW n m, input-select (KEY_A_DVI / KEY_A_RGB / KEY_A_VIDEO), SWAPIN / SWAPWIN
  - queryable    # inferred: 25 documented query commands
  - levelable    # inferred: BRIGHTNESS / CONTRAST / SATURATION / HUE / position / size continuous params (0-1000)

Actions

# Command template: "!{addr}<COMMAND>[ <n>][ <m>]<CR>" - see Transport for {addr} and <CR>.
# kind: action  = a `!` command;  kind: query = a `?` query (response is a `~` line, see Feedbacks).
# Entries marked "Not Available" are documented command rows the source explicitly flags as
# non-functional on the DIDO Jr.; the opcode is recognized by the protocol but performs no operation.

Notes

  • Device class: multi-window video processor / scaler / video-wall controller. Inputs: 1× DVI-I (DVI-D + RGBHV/YPbPr) and 1× S-Video (4-pin mini-DIN). Output: scaled DVI/RGB.

  • Addressing: every command embeds a 3-digit address (000–254, or ***/255 broadcast). {addr} in the command templates above is this 3-digit field. Set a unit's address with RSADDR n or via the on-device System Settings; the IR remote is also addressable to limit cross-talk between co-located DIDO Jr. units.

  • Wire format: <CR> = 0x0D. Responses are UPPERCASE; !/? are not case-sensitive.

  • Multi-unit chaining: first unit talks RS-232 to the controller; its RS-485 (+/−/GND) loops in parallel to all other units' RS-485 ports. Aurora sells a "DIDO LOOP KIT" for this. Each chained unit needs a unique address (0, 1, 2, …) and the last unit needs termination enabled.

  • Output resolution table (OUTFORMAT n) — verbatim from source:

    n resolution n resolution n resolution
    0 VGA 60Hz 11 SXGA 60Hz 22 USER 02
    1 VGA 72Hz 12 SXGA 75Hz 23 USER 03
    2 VGA 75Hz 13 SXGA 85Hz 24 USER 04
    3 SVGA 60Hz 14 WXGA 60Hz 25 USER 05
    4 SVGA 72Hz 15 UXGA 60Hz 26 USER 06
    5 SVGA 75Hz 16 WVGA 60Hz 27 USER 07
    6 XGA 60Hz (806 px) 17 480P 28 USER 08
    7 XGA 60Hz (807 px) 18 576P 29 USER 09

    9 XGA 75Hz 20 1080P 31 (unused)
    10 XGA 85Hz 21 USER 01 32 (unused)

  • WINDOW n m valid inputs (m): DVI_A, RGB_A, SVIDEO_A (channel B inputs are documented but flagged Not Available on this model).

  • "Not Available" rows: the source command table lists audio (MUTE/VOLUME/AUDIOINPUT/AUDIOOUTPUT/AUDIODELAY) and channel-B input commands and explicitly marks them "Not Available" for the DIDO Jr. They are retained here as documented protocol opcodes; treat as no-ops on this hardware.

  • Numeric responses: source notes that multi-digit ASCII decimal responses must be converted to a true hexadecimal value for bit-field decoding (e.g. ASCII 13 → 0x0D).

  • Firmware compatibility: check the serial-number batch prefix (bbbb-SNxxxx) against the firmware's supported hardware revision before flashing; some features depend on model/batch.

Known Gaps

- "source is the RS-232 protocol chapter only; no voltage/power specs, no mechanical drawings, no full firmware compatibility matrix. Marketing/connector specs beyond the control port are out of scope."
- "allowed port range.\""
- "filename constraints.\""
- "per-field enum/value tables for each query response are not exhaustively tabulated in source beyond the INFO example."
- "exact percent range bounds for OSDTRANS / PIPTRANS not stated (source: \"value in percent\")."
- "source contains no asynchronous/event-push definitions."
- "no macro sequences documented in source."
- "discrete baud-rate steps within 2400–115200 not enumerated (only the range and 115200 default are stated)."
- "exact percent bounds for OSDTRANS / PIPTRANS not stated."
- "per-query response value tables (other than INFO) not exhaustively tabulated in source."
- "flow control not explicitly stated by \"8N1\"."
- "no firmware version compatibility range stated (single INFO sample reports v1.11 / Rev 8649 / 2005-08-29)."
