5.1.4 Connecting RS-485
The default baudrate of the 62000H Series DC Power Supply is set to 115200 and the parity
check is set to None. The RS-485 interface is a half-duplex two-wire differential signaling
transmission system and only RS485_P and RS485_N signals are required for data
transmission. The connector is the same as the RS-232C (9-pin D type male). Table 5-3 lists
the pins and signals of the RS-485 connector.
