SCADAPack Communications and Radio Telemetry Configuration
Key Takeaway
How to configure SCADAPack communication options — serial, Ethernet, radio modem, cellular, and satellite for remote oilfield and pipeline SCADA.
Quick Answer
SCADAPack RTUs communicate via RS-232, RS-485, Ethernet, radio modem, cellular, and satellite links. Configure communication ports in Telepace Studio, matching protocol (DNP3/Modbus) to the transport medium and SCADA master requirements.
Communication Options
- RS-485 serial — Multi-drop DNP3/Modbus over twisted pair or radio. Configure baud rate, RTS/CTS handshaking, and turnaround delay.
- Ethernet — TCP/IP for DNP3 over TCP, Modbus TCP, and Telepace Studio remote access.
- Licensed radio — 900MHz or UHF narrowband for long-range point-to-multipoint.
- Spread spectrum — Unlicensed 900MHz or 2.4GHz for shorter range.
- Cellular — 4G LTE modems for remote sites without radio infrastructure.
- Satellite — VSAT or Iridium for extremely remote locations.
Radio Integration
Connect radio modems to SCADAPack serial ports. Configure RTS/CTS handshaking and turnaround delay in Telepace Studio to match the radio's keying time.

Frequently Asked Questions
Yes. SCADAPack supports cellular via external 4G LTE modems or integrated cellular on x70 series. DNP3 over TCP/IP or Modbus TCP is used over cellular links.
RS-485 supports up to 32 standard loads per segment. Practical limits are 10-20 RTUs per segment depending on baud rate and data volume.
