ການ​ນໍາ​ໃຊ້

ການຕັ້ງຄ່າໂຮງງານ

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,
ກະລຸນາຕິດຕໍ່ສະຫນັບສະຫນູນດ້ານວິຊາການຂອງພວກເຮົາ.

Ordinary users need to provide the following parameters at the receiving end to our company to make factory settings;

	RS232	RS422	RS485
ທີ່ຢູ່ອຸປະກອນ	01(Default Value)	01	01
MODBUS Connection Mode	RTU (Default Value)	RTU	RTU
RS Baud Rate	9600(Default Value)	9600	9600
RS Connection Type	RS232 (Default Value)	RS485	RS485
Half Duplex / Full Duplex	Full Duplex (Default Value)	ເຕັມ Duplex	Half Duplex
Serial Communication Electrical Level	ໂໝດປົກກະຕິ (ຄ່າເລີ່ມຕົ້ນ)	ໂໝດປົກກະຕິ	ໂໝດປົກກະຕິ

ຄໍາຮ້ອງສະຫມັກ

Users can connect Net485 to UPS and MODBUS receiver or PC for testing.
ເນື້ອໃນຕໍ່ໄປນີ້ແມ່ນ example 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.

1. Run [Modscan], click Connection, select the PC serial port connected to the Net485 output, and Modbus related settings. As shown in the figure.
   
   
2. Select the holding register and start address to view ຂໍ້​ມູນ​ທີ່​ໄດ້​ຮັບ​.
   
3. Look up the UPS data represented by the corresponding address bit in the provided register address file.
