(2)  Set Terminating Resistor 

The last unit of connected  MBD-D  requires the terminating resistor settings.  Turn ON the 

switch <1> of <Resistor> to activate, and turn it OFF to inactivate the terminating resistor. 

 

(3)  Set Address 

Press and hold the <SETTING> circle button for longer than 3 seconds to start settings menu.   

You can change the address of the MBD-D by pressing the triangle button.  Digits can be 

changed by pressing the circle button shortly.    After settings are completed, press and hold 

the circle button for longer than 3 seconds to close the settings menu.    Set the same figures 

to the address as C30S.  The allowable figures are from 1 to 250.    Note that communication 

may fail if an address is duplicated among multiple units of MBD-Ds.   

 

5.4 

Direct Communication with MBD-D 

The procedure to transmit data directly without C30S is as follows. 

 

Direct Communication Settings 

From the rear of the MBD-D, connect the pin No.4 of RS485 and D+ (or RX(+) and TX(+)) of 

RS485 of the desired device, and connect the pin No.5 and D- (or RX(-) and TX(-)).  After the 

connection has been made, check the transmission speed, terminating resistor, and address 

as described above. Refer to Table 3-1 for connector pin allocation. 

After checking them, set the transmission speed consistent at the target device.. 

Other settings are as follows; 

Data Bit : 8 Bit 

Stop Bit : 1 Bit 

Parity : None 

 

5.5 

Modbus Protocol 

The MBD-D uses Modbus protocol for communication. 

For detailed information on Modbus, visit the web site of Modbus.org. 

 

The Modbus protocol message is composed as follows; 

Device Address 

Function Code 

Data 

Error Check (CRC) 

 

 

Device Address

: The address of each MBD-D as a slave. Set different addresses to all the 

MBD-D units to be connected. If there is another MBD-D with the same address, it may 

invite communication trouble.
