RS-485 serial connection setup 117
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
Connect to Meter window, click the Direct 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
Meter>Communications Settings menu 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
Direct
connection uses the user-specified serial communication settings. If desired, set the
Modem and/or optional Ethernet 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.
