How to Network an RS485 Serial Server: Bus Wiring, Network Modes, and Polling Acceptance
Network RS485 devices with a valid local bus, supported TCP or COM access and one coordinated poller. Verify response identity and recovery beyond a connected session.

RS485 to Fiber Converter: Transparent Transmission, Direction Control, and Parameter Selection
Extend RS485 across fiber while retaining local bus rules, addressed exchanges and application timing. Verify direction control and both electrical segments independently.

RS232 vs RS485 vs CAN: Electrical Interfaces, Buses, and Arbitration
Compare serial electrical levels, bus access and CAN arbitration. Check pin assignments, timing and application protocols before choosing a converter or fiber extension.

How to Connect Modbus RTU Devices to Modbus TCP with a Serial Server
Connect Modbus RTU devices through a gateway that supports protocol conversion. Verify serial settings, unit IDs, register reads, timeouts and TCP connectivity.
