Unit
Procedure
Step 1 Set monitoring parameters for the independent deployment AI_DI unit.
Set the address of the independent deployment AI_DI unit to 1 or 2 by setting its DIP switch.
The DIP switch consists of toggle switches 1–4 (from left to right). Toggle switches 1–3
specify the address of the independent deployment AI_DI unit. Toggle switch 4 specifies the
address of the RS485 build-out resistor. 0 indicates OFF, and 1 indicates ON.

connected devices are displayed in the Number of connected devices list.
− If the PDC DC meter does not connect to the ECC800 properly, check whether the
cable between the PDC DC meter and the ECC800 is connected properly, whether
the PDC DC meter and ECC800 are running properly, and whether the input
parameters are consistent with the PDC DC meter parameters.
The device address for the independent deployment AI/DI unit can only be set to 1 or 2.

If the signal quality is poor due to signal reflection caused by long communications cables (longer than
50 m), set toggle switch 4 to ON for the furthest independent deployment AI_DI unit. After the DIP
switch settings are modified, power off and restart the independent deployment AI_DI unit for the new
settings to take effect.
