Lumens DC265 Control Spec

Summary

The Lumens DC265 is a document camera (visual presenter) controlled via RS-232 serial using a binary packet protocol. Commands are 6-byte frames (0xA0 header, command byte, 3 parameter bytes, 0xAF footer). The spec also applies to the DC260 model. The protocol supports power control, zoom, focus, iris, white balance, image capture, playback, and various image processing functions.

Notes

• Binary protocol: all commands are 6-byte frames starting with 0xA0 (STX) and ending with 0xAF (ETX).
• Response byte 5 indicates status: 0x00 = ACK (success), 0x01 = NAK (error in command packet), 0x10 = IGNORE (unsupported or busy).
• Multi-byte integer parameters use little-endian encoding (low byte first, high byte second).
• The document references both DC265 and DC260 models; commands appear to be shared between them.
• Pan PBP step range and zoom position range vary depending on the active resolution mode (SXGA, 720P, or XGA).
• Register commands (reg1/reg2/reg3, command bytes 0x52/0x53/0x54) are documented but their function is not described.

Known Gaps

- "source does not document unsolicited notifications from the device"
- "no multi-step sequences described in source"
- "source does not contain safety warnings or interlock procedures"
- "no mention of command timing, inter-command delays, or timeout behavior"
- "resolution mode selection command not identified in source"
- "firmware version compatibility not stated in source"
- "reg1/reg2/reg3 register functions not documented"
- "Focus Direct return packet uses P3 for speed but standard return format has status at byte 5 -- behavior unclear"
