149 Control unit communication
149.01 Control unit node ID Unique node identification in the communication
network.

1 … 32 1 = 1
149.03 Control unit baud rate Maximum communication baud rate for the
inverter. Reliability of the communication may
require lower setting, depending on the electrical
characteristics of the wiring.

149.06 Refresh settings Applies settings from parameters 149.01, 149.03,
149.20, 149.21, 149.23 and 149.24.
Note: Changing the settings will cause a
communication break. The control unit
reconnects automatically, but other bus masters
may need to be reconnected manually.
Done
Done Refresh done. 0
Configure Refresh parameters 149.01 and 149.03. The
value reverts automatically to Done.

149.20 Terminal X1, X8 Shows currently active protocol on terminals X1
and X8.
Note: Terminals X1 and X8 are internally
connected and share the same UART.
Terminal X1 is intended for connecting the
remote PVS-AP-L control unit.
This parameter is read only.

149.21 Terminal X2 Selects the active protocol on terminal X2. Modbus RTU
Modbus RTU 0
Control unit Swaps the protocols such that the protocol on
terminal X2 moves to terminals X1 and X8, and
the control unit protocol becomes active on
terminal X2.
Note:
• This is a volatile setting, meaning, the setting
reverts back to the control unit protocol on
terminals X1 and X8 whenever the inverter is
power cycled.
• Enabling the control unit protocol on
terminal X2 also enables firmware update over
terminal X2.
