This manual introduces the Samsung Techwin S-Protocol, including the definition and usage of the protocol.
The Samsung‑Techwin Samsung‑T Protocol User Manual provides the command set, packet formats, and timing requirements for communicating with Samsung speed dome cameras over RS‑485/RS‑422. It includes a detailed description of each command, such as pan/tilt, zoom, focus, OSD menu control, preset handling, swing, and sequence operations.
The document also specifies the communication parameters (baud rate, data bits, parity, stop bits) and offers sample protocol strings for common actions. An appendix lists digital zoom parameters for the SCP‑3120 camera series.
| Communication mode | RS-485/RS-422 Asynchronous |
|---|---|
| Baud rate | 9600 bps |
| Data bits | 8 bits |
| Parity | None |
| Recommended minimum control period | 70 ms |
| Maximum response time | up to 7 seconds |
The manual recommends a minimum period of 70 ms between control signals.
The protocol operates at a baud rate of 9600 bps.
