Użu

Settings tal-Fabbrika

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,
Jekk jogħġbok ikkuntattja l-appoġġ tekniku tagħna.

L-utenti ordinarji jeħtieġ li jipprovdu l-parametri li ġejjin meta jirċievu l-prodott lill-kumpanija tagħna biex jagħmlu s-settings tal-fabbrika;

Applikazzjonijiet

Users can connect Net485 to UPS and MODBUS receiver or PC for testing.
Il-kontenut li ġej huwa 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.

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 id-data riċevuta.

Look up the UPS data represented by the corresponding address bit in the provided register address file.
