  "notes": "RS-485 remote I/O: the module reaches Modbus Connect through a Modbus RTU-to-TCP gateway, and the serial block holds the factory settings the gateway must use. Addressing: the manual's Modbus mapping table prints Modbus reference numbers (\"ADDR 0X\" 00001..., \"ADDR 4X\" 40001...) and this seed stores the equivalent zero-based wire addresses (reference minus one), as the ADAM-6000 seeds in this library do. Source: Advantech \"ADAM-4000 Series User Manual\" Ed.9 (2023), Appendix G.1 \"ADAM-4000 I/O Modbus Mapping Table\", item 7 \"ADAM-4050 15 or *16-ch Digital I/O Module\" (manual page 268); factory communication settings from chapter 2.2 \"Default Factory Settings\" (baud rate 9600 bit/s, address 01 hexadecimal) and Appendix H.1 (initial COM settings 9600 baud, N-8-1). The ADAM-4050 has seven digital inputs and eight digital outputs; the eighth input (channel 7) exists only on the ADAM-4050-F, as the table's footnote \"* New Input for ADAM-4050-F\" states. The module has no analog channels and no counter block in this map. A Modbus-version module can leave the factory set to the ADAM ASCII protocol; Appendix H.1 documents switching it to Modbus with the Adam/Apax .NET utility before the map above applies."
