Biamp SPM522D Control Spec

Summary

Biamp Advantage SPM522D Stereo Preamp/Mixer. RS-232 serial control via Control Button Emulation (one-way) and Advanced Computer Control (two-way, query-capable). Commands use "pseudo-hex" notation (ASCII 0x30-0x3F representing nibbles 0x0-0xF). Each Advanced command requires Device Type Bitmask (0x04 for SPM522D) + Device Number Bitmask prefix.

Transport

protocols:
  - serial
serial:
  baud_rate: 2400
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source: "Neither hardware (DTR) nor XON/XOFF...handshaking is supported"

Traits

- routable    # inferred from do-source-select and per-button source-select commands
- queryable   # inferred from get-version, get-button-definition, get-source-settings, get-preset-definition, read-memory
- levelable   # inferred from set-volume, do-volume-action, do-tone-action, do-balance-action

Events

# UNRESOLVED: source does not document unsolicited events.
# Device only emits echoes and query responses; no async notifications described.

Macros

# UNRESOLVED: no multi-step macro sequences documented in source.

Safety

confirmation_required_for:
  - set_factory_defaults  # source includes the "<>" dummy prefix specifically "to help prevent an accidental restoration of the factory defaults due to an error in data transmission"
  - write_memory          # source: "It also provides the computer with a method for totally messing things up." Checksum required; mismatched checksum causes command to be ignored.
interlocks: []
# UNRESOLVED: no physical-safety, voltage, or interlock warnings in this protocol document.

Notes

• All Advanced Computer Control commands require Device Type Bitmask byte = 04 (pseudo-hex) for SPM522D — bit 2 of the Device Type Bitmask. Other Advantage product types (DRC=0x01, EQ28X=0x02, PMX84=0x08) ignore commands not targeting their bit.
• Device Number Bitmask dd is two pseudo-hex nibbles; each of the 8 bits selects one of up to 8 SPM522D units on the bus. A unit only responds when its bit is set.
• "Pseudo-hex" format: each 4-bit nibble is encoded as ASCII 0x30 + nibble_value, so nibbles 0xA-0xF appear as :, ;, <, =, >, ? (not standard A-F).
• Flow control: device has only a single-character input buffer. Each received char is echoed; the computer must wait for the echo before sending the next char. Hardware DTR and XON/XOFF are not supported.
• ASCII control chars (0x00-0x1F), SPACE (0x20), A (0x41), a (0x61), and {-DEL (0x7B-0x7F) are accepted but treated as no-op — they may be interspersed freely (even between two nibbles of a pseudo-hex parameter) without affecting command parsing. Bytes >= 0x80 are reserved.
• Responses are terminated with <CR> (0x0D). An internal "Opt. X" DIP switch (off by default) appends <LF> (0x0A) after each <CR>.
• Device select prefix codes (l-z, 0x6C-0x7A) for Control Button Emulation address up to 4 devices and were added in firmware >= 02-Jul-95; earlier units ignore them.
• set_volume requires firmware >= 23-Aug-95 per source.
• Connector pinout, cable wiring, and physical RS-232 port location are not documented in this excerpt.

Known Gaps

- "TCP/IP, REST, UDP, OSC not mentioned in source — RS-232 only."
- "source does not document unsolicited events."
- "no multi-step macro sequences documented in source."
- "no physical-safety, voltage, or interlock warnings in this protocol document."
- "firmware compatibility ranges other than the two dates explicitly stated; physical connector type and pinout; max cable length; default device number assignment procedure (DIP/jumper config not described in this excerpt)."
