Frequently Asked Questions (FAQ – QA Format)

Q1: What do you use the FC‑DCOM‑232/485 for?
A1: It bridges RS‑232 and RS‑485 devices in industrial automation systems.

Q2: Can both RS‑232 and RS‑485 operate simultaneously?
A2: No — only one port is active at a time based on configuration.

Q3: What is the maximum RS‑485 cable length?
A3: Up to approximately 1,200 m, depending on baud rate and network setup.

Q4: Is the RS‑485 port isolated?
A4: Yes — it includes opto-isolation to protect against electrical noise.

Q5: Does it support Modbus RTU protocol?
A5: Yes — supports Modbus RTU in both master and slave modes.

Q6: What power does the module use?
A6: Powered with 5 V DC via the controller (no external supply required).

Q7: What environmental specs does it meet?
A7: Operates between –40 °C to +70 °C and up to 95% humidity (non-condensing).

Q8: How is baud rate configured?
A8: Configurable via software or via jumpers—standard rates up to 115.2 kbps for RS‑232 and up to 2 Mbps for RS‑485.

Q9: Can the module be hot-swapped?
A9: Yes — hot-swap capability is supported, depending on controller architecture.

Q10: What are its mounting options?
A10: It mounts easily on standard DIN rails (TS32/TS35 × 7.5).
