4.6 Method 2: Set Modbus ID Manually
An alternate approach is to manually assign IDs to the MVR-300 devices prior to wiring.
There is a tool for this as well. Contact Bacharach for further information.
Wire a single MVR-
300’s Modbus port to the controller’s Modbus terminal block. It is
recommended to use the EZ-wire kit included with the MVR-SC controller for ease.
1. From
Settings
, open the
Set Modbus ID
screen to select and apply a specific Modbus ID.
2. Tap
Search
to connect to the device. If the unit does not have factory Modbus ID #1, this
can be restored by doing a factory reset.
In case the MVR-300 has had its Modbus ID changed by the user to some ID other than
the default address 1, do the following to reset to factory settings:
a. Power OFF the MVR-300. Set dipswitch-8 to the ON position.
b. Power ON the MVR-300 (buzzer should sound). Reset dipswitch-8 to the OFF
position (buzzer should turn off).
