1.3.2
RS485 nterface (standard)
The RS485 interface is one of the equipment communication interfaces. It
is used for remote control and can effectively transmit signals under long-distance conditions
and in environments with high electronic noise. RS485 interface makes it is possible to connect
to local network and configure multi-drop communication link.
1.3.2.1 Location of RS485 interface
The RS485 interface is located on the rear panel of power supply (Figure 1-9

1.3.2.2 Connection of RS485 interface
The RS485 interface of ESA series adopts "two-wire + signal ground" wiring. In low-speed,
short-distance, non-interference occasions, ordinary twisted-pair wire can be used. Conversely,
in high-speed and long-line transmission, RS485 special cable (STP-120Ω 18 AWG) (one pair)
with impedance matching (generally 120Ω) must be used. In the environment with severe
