Clipsal 5500PACA Control Spec

Summary

The Clipsal 5500PACA (Pascal Automation Controller) attaches to a C-Bus network via the C-Bus Serial Interface, an RS-232 gateway that converts the C-Bus protocol to/from asynchronous serial. This spec is built from the C-Bus Serial Interface User Guide (CBUS-SIUG Issue 1.17, 9 Dec 2008), which documents the protocol used by the PC Interface (5100PC, 5500PC) and C-Bus SIM (5000SM, 5000SM/2). Control surface covers Point-to-Point (CAL) device management, Point-to-Multi-Point (SAL) Lighting Application commands, status polling, and Serial Interface option/parameter configuration.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600  # default factory value; selector param $3D allows 9600/4800/2400/1200/600/300
  data_bits: null  # UNRESOLVED: data bits not stated in source
  parity: null  # UNRESOLVED: parity not stated in source
  stop_bits: null  # UNRESOLVED: stop bits not stated in source
  flow_control: null  # UNRESOLVED: flow control framing not stated; XON/XOFF is a configurable Serial Interface option (Interface Options 1 bit 2), not RS-232 hardware flow control
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - queryable  # inferred: Status Requests, IDENTIFY, RECALL, GETSTATUS queries documented
  - levelable  # inferred: RAMP to LEVEL lighting commands documented
  - routable   # inferred: Point-to-Point, Point-to-Multi-Point, Point-to-Point-to-Multi-Point routing documented

Actions

# All payloads verbatim from CBUS-SIUG Issue 1.17. Lighting SAL commands are
# transported inside a Point-to-Multi-Point frame: leading "\" + header ($05) +
# application ($38) + SAL Data + optional checksum + <cr>. The `command:` field
# below shows the SAL Data opcode portion verbatim; full frame assembly is the
# integrator's responsibility per sections 4.2.9.2 and 6.4.
# Checksum is appended only when the SRCHK option (param $30 bit 3) is set.

# --- Special characters / Serial Interface control (section 4.2) ---

Notes

• Source document is CBUS-SIUG Issue 1.17 (9 Dec 2008) — C-Bus Serial Interface & C-Bus Development Kit — describing Serial Interface version 4.0.00 and higher. It covers the protocol used by 5100PC, 5500PC, 5000SM, 5000SM/2 PC Interface / SIM devices.
• The 5500PACA (Pascal Automation Controller) is the target product per input metadata but is not explicitly named in the refined source document; coverage of the 5500PACA's Pascal/PICED programming interface, physical RS-232 pinout, voltage, and current ratings is out of scope of this source.
• All commands sent to the Serial Interface terminate with <cr> ($0D); max 45 characters between leading \ and <cr> (section 4.2.2).
• All Serial Interface checksums are 2's-complement mod-256 sums of the preceding hex byte pairs; appended only when SRCHK option set (section 3.6).
• Default baud rate is 9600; lower rates (4800/2400/1200/600/300) selectable via param $3D but not recommended due to limited internal buffering (section 10.3.3).
• Serial Interface firmware <3.11 is pre-release; v3 firmware ≤3.16 has a baud-reversion bug limiting those units to 9600 baud (section 11).
• Default factory Interface Options 1 ($30) value is $00 (BASIC Mode, no options).

Enumerated: 4 special chars, 16 ramp opcodes + ON/OFF/TERMINATE, 2 status requests + legacy FA, 4 CAL commands, 18 IDENTIFY attrs ($00-$11), 2 param-set methods, 7 settable params, autoset, 9 reply types, read-only params noted omitted. Safety from section 5/3.4/4.2.9.2/10.3.4/10.2.2.

verdict: verified
checked_at: 2026-08-05T08:14:27.946Z
matched_actions: 58
action_count: 58
confidence: medium
summary: "All 58 spec actions map 1:1 to SAL opcodes (6.3), CAL commands (7.1), IDENTIFY attrs $00-$11 (7.2), and parameter methods (10.2/10.3) in the source. (12 unresolved item(s) noted in Known Gaps.)"
```

## Known Gaps

```yaml
- "The 5500PACA is named only in the input metadata; the refined source document covers the C-Bus Serial Interface protocol generically and does not explicitly mention the 5500PACA model. Voltage/current/power specs, physical wiring, and PICED/Pascal programming interface are out of scope of this source."
- "data bits not stated in source"
- "parity not stated in source"
- "stop bits not stated in source"
- "flow control framing not stated; XON/XOFF is a configurable Serial Interface option (Interface Options 1 bit 2), not RS-232 hardware flow control"
- "no other unsolicited event classes documented in source."
- "5500PACA model not explicitly named in source; relationship of this protocol guide to the 5500PACA's primary programmable interface is unconfirmed."
- "serial data bits, parity, stop bits, hardware flow control not stated in source."
- "physical connector pinout, voltage, current, power specs not stated in source."
- "firmware version compatibility range for 5500PACA not stated."
- "full CAL command catalogue (unit-specific commands \"subject to change without notice\" per section 7) — only the common subset tabulated in section 7.1 is enumerated here."
- "non-Lighting C-Bus Applications (CBUS-APP document set) not in source; only the Lighting Application $38 SAL subset is enumerated."
