7.

Override the Mark III Serial Port B parameters to 19200 baud and Modbus ID 32 by 

setting CPU Board switch S2-1 to the CLOSED position (down toward the board) (or 

toggle the switch S2-1 if already in the CLOSED position).  

8.

From Daniel MeterLink 

 window, click the 

button to connect to 

the meter record established above. Daniel MeterLink connects to the meter with the 
user-specified serial communication settings.

9.

After connecting to the meter, configure the Mark III with the desired communication 

parameters via the Daniel MeterLink 

enu path.

10.

Disconnect Daniel MeterLink from the Mark III meter.

11.

Disable the Port B override by setting CPU Board switch S2-1 to the OPEN position (up 

away from the board).   

12.

In Daniel MeterLink, edit the meter directory record established above so that the 

 

connection uses the user-specified serial communication settings. If desired, set the 

 and/or optional 

 connection settings to the user-specified values.

Serial Port B remains in the override mode until either (1) the port configuration is 
changed (via software), (2) two minutes have elapsed at which time the port reverts to 
its current configuration), or (3) CPU Board switch S2-1 is changed back to the OPEN 
position.

At this point, the Daniel 3410 Series Ultrasonic Gas Flow Meter will only communicate at 
the user-configured settings.
