# ✅ NL-43 / NL-53 Command Format — Verified Quick Reference
|
||
|
||
This cheat sheet lists confirmed working command formats for NL-43 and NL-53 devices, based on the official Rion Communication Guide (pages 30–96).

|

|
||
## 🧠 Protocol Basics
|
||
|
||
- **Command format:** `Command,Param[CR][LF]` — no space after comma.
|
||
- **Query format:** `Command?[CR][LF]`
|
||
- **Line endings:** CR = `\r` (0x0D), LF = `\n` (0x0A), always use both.
|
||
- **No `$` prefix** unless specifically required (e.g. system control).

## ⚠️ Common Mistakes to Avoid
|
||
- ❌ Don’t include a space after comma: `Measure, Start` → invalid.
|
||
- ❌ Don’t use numeric params if the spec requires strings.
|
||
- ❌ Don’t forget `\r\n` line ending — most commands won’t work without it.
|
||
- ❌ Don’t send multiple commands at once — insert 1s delay between.
