- Isolates, repeats/converts and switches between RS-232 and RS-485 signals
- Various isolation options available
- Protocol Independent
- 3-port Master/Slave, Hub, or switch between ports A & C or B & C.
- 3-wire operation (TX, RX, GND) for one RS-232 port
- 2-wire operation (T+, T-, GND) for two RS-485 ports
- Voltage Input : 9 to 36 Vdc – Accepts unregulated 9 to 36v DC power supply. Suitable for industrial 24vdc supplies, 12v or 24v battery systems, or supply from any low-cost DC transformer pack. Fully in-rush and surge protected.
- 4-port Isolation – 4 of 4 ground isolation means all data grounds are 100% isolated from each other and the power supply ground. Like 3 of 3 ground design, this is always the safest design option. All redundancy – supporting products (hubs, arbitrators etc) are based on this design.
