استعمال
فيڪٽري سيٽنگون
Net485 will be set according to the parameters related to the receiving data side provided by the user before shipping. Because the Net485 parameter setting requires the user to use a direct serial cable (1 to 1, 2 to 2… 9 to 9) connected to the computer side and set up using HyperTerminal. The external card requires the user to remove the case. To see the advanced user settings,
مهرباني ڪري اسان جي ٽيڪنيڪل سپورٽ سان رابطو ڪريو.
Ordinary users need to provide the following parameters at the receiving end to our company to make factory settings;
| RS232 | RS422 | RS485 | |

درخواستون
Users can connect Net485 to UPS and MODBUS receiver or PC for testing.
هيٺ ڏنل مواد هڪ اڳوڻي آهيample of [Modscan] software testing.
If you connect Net485 to PC side for testing, you need to prepare your own RS485 to RS232 cable. You can refer to the following diagram for the connection method.
- Run [Modscan], click Connection, select the PC serial port connected to the Net485 output, and Modbus related settings. As shown in the figure.
- Select the holding register and start address to view حاصل ڪيل ڊيٽا.
- Look up the UPS data represented by the corresponding address bit in the provided register address file.
