4. Configure the Mark III Port B for RS-232 operation by setting the CPU board and Field
Connection board switches as indicated in the table below (see Figure 3-24 for switch
bank locations):
5. 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).
6. From Daniel MeterLink
Connect to Meter window, click the Direct button to connect to
the meter record established above. Daniel MeterLink will now connect to the meter
with the user-specified serial communication settings.
7. Configure the Mark III meter with the desired communication parameters via the Daniel
MeterLink
Communication Settings window.
8. Disconnect Daniel MeterLink from the Mark III meter.
9. Disable the Port B override by setting CPU Board switch S2-1 to the OPEN position (up
away from the board).
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.

Note that Serial Port B remains in the override mode until either (1) the port
configuration is changed (via software), (2) two minutes has 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 Mark III meter will only communicate at the user-configured settings
