Known Gaps

- "wireless LAN spec not detailed in source; model number exact match not confirmed"
- "no standalone variable parameters outside of action/feedback flow; all settable params are action-driven"
- "no unsolicited event notifications described in source; device only responds to commands"
- "no multi-step macro sequences documented in source"
- "wireless LAN unit manual reference only; TCP port 7142 stated for LAN but serial must be manually configured at one of 5 baud rates; firmware version compatibility not stated; input terminal value mappings deferred to appendix not included in source"
