CAS indicators
Six indicators sharing one house format, plus the CI-200's slimmed-down variant. Field layouts here were read off rendered pages rather than extracted text — the manuals draw them as figures whose cells extraction returns as a jumble.

Catalogue entries
Further CAS documentation is held but not yet catalogued: the GW Series and the X320, both documented and both their own work. Nine other CAS manuals in our set cannot be built from at all — label printers, crane scales and scanned images with no text layer.
Models and the formats they offer
| Model | Output formats | Default baud |
|---|---|---|
| CCB | CAS Standard ★ | 9600 |
| CI-200 | A&D 18-byte · CAS Standard | 9600 |
| CI-2001A | CAS Standard ★ | 9600 |
| CI-2001B | CAS Standard ★ | 9600 |
| CRC100 | CAS Standard ★ | 9600 |
| CRD | CAS Standard ★ | 9600 |
The formats
Each one is a separate parser, because which format a site chose is not reliably detectable from the stream — you pick what the box's own menu is set to. Example frames below are produced by that format's own encoder and read back through its own parser.
CAS Standard
The CAS house format
The ASCII line every indicator in this suite transmits, documented identically across the CI-200, CI-2001A and B, CRC100, CRD and CCB. A stability header, a gross/net header, a device address, a lamp-status byte, an eight-character weight and a two-character unit.
⚠ Two lamp-status bits are deliberately not decoded, because the manuals contradict each other: the CI-200 labels one bit gross where the CRC100 labels it net, and they disagree on two more. Reporting either reading would be a coin flip on whether a weighment is gross or net — and the gross/net header already carries that unambiguously, so that is what we trust. The bits both manuals agree on are reported; the rest are left alone.

A&D 18-byte
The CI-200's 18-byte "for AND" format
The house format with the device ID and lamp-status byte removed. Same headers, same weight field, same unit.
⚠ It specifies different line settings from the rest of the suite — seven data bits with parity, against the house format's eight and none. That is a reader-configuration matter rather than a parsing one, but it is the reason an installer picking this entry must also change the port's framing. Note it is a CAS entry, not an A&D one, and it is not byte-identical to the real A&D formats.

Is your indicator here?
If it is, it works out of the box — pick the model and the format its menu is set to, and readings publish over MQTT, Modbus TCP, OPC UA, REST and six more transports at once. If it is not, describe the line's fields in the console and multiIO decodes it anyway, or send us the manual's serial chapter: that is how most of this catalogue got here.
