2.3.5 Serial Port (RS232 and RS485)
EG500 provide isolated serial COM ports, 1x RS485 and 1xRS232, the PIN B1_15 defined
RS485_A (difference line high), PIN B1_13 defined RS485_B (difference line low).
While the PIN B1_12 defined RS232_Tx (transit line), PIN B1_10 defined RS232_Rx (receive
line), PIN B1_8 defined RS232_GND (reference potential).
A 120 Ohm termination resistor for RS485 has been installed inside.
Check the above application wiring for reference.
2.3.6 DI (Digital Input)
EG500 provide 6x DI to detect the status of outside digital signal, also support count mode to
calculate the frequency.
The DC input voltage is 24V. The 6 digital input are isolated to each other.
Check the above application wiring for reference.
