توصيلات RS485 لسلسلة Autarco MH

تصف هذه الصفحة الاتصال بعاكس هجين من سلسلة Autarco LH عبر Modbus-RTU (rs485). يُعيَّن العاكس على العنوان 1 افتراضيًا. واجهة RS485 عبارة عن موصل ذي 4 دبابيس يُسمى "COM"، ويقع في الجزء السفلي من العاكس خلف لوحة واقية. يظهر الموضع الدقيق داخل المربع البرتقالي في الصورة أدناه:

عند إلقاء نظرة فاحصة، يبدو المنفذ كما يلي:

يجب استخدام موصل مناسب لهذا الموصل ذي الدبابيس الأربعة الموجود على عاكس Autarco لتوصيله بـ SmartgridOne Controller. في SmartgridOne Controller، يمكن توصيل العاكس بمنفذ RS485. تكون التوصيلات كما يلي:

RS485 Wiring

For correct RS485 wiring: Follow the guidelines for RS485 wiring.
If the wiring shown in the table below is incorrect, please let us know.
There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

Device	SmartgridOne Controller model OM1	SmartgridOne Controller model IG8	RS485-USB converter	RS485-Ethernet converter
Pin 3	RS485 A	RS485_POS	RS485 A	TX+
Pin 4	RS485 B	RS485_NEG	RS485 B	TX-
N/A	RS GND	GND	Not available	G

NOTE: RS485 Device Addresses

You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.
