Siffofin

Net485 is to convert RS232 signals of [MegaTec] and other protocols to RS422 or RS485 signals.

Siffofin:

1. CPU is ARM 266MHz 32Bit, system clock is 208MHz, flash memory is 4M, SDRAM is 16M, and built-in watchdog.
2. Net485 normal operating temperature and humidity range is 0℃ to 50℃ and 5% to 95%.
3. FCC, Class B, CE, Rosh approved.

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,

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 bayanan da aka samu.
   
3. Look up the UPS data represented by the corresponding address bit in the provided register address file.
