Modem Initialization String
The setup register labeled ModemInit is available for 9330 and 9350 meters with
internal modems, and defines the initialization string for the internal modem (by
default, the modem is factory configured to answer on one ring). You should not
require changes to the ModemInit string for normal operation. If you require
advanced modem functionality, you can customize the ModemInit register with a
string up to 47 characters long.
CAUTION
The ModemInit string is automatically sent to the internal modem when the ModemInit setup register is
changed, when the meter is powered up, or when the baud rate of the modem’s Communications
module is changed.
Communications Protocols
By default, all COM ports are configured to use the ACCESS protocol. If you want
to make use of Modbus RTU, DNP 3.00, or GPS configurations, you need to
configure Protocol setup register the Communications module that controls the
port you want to use.
NOTE
The Factory Protocol is reserved for the use by Siemens Customer Service.
Power Quality Setup (9350)
For the 9350 meter, power quality parameters can be set up using the Sag/Swell
module. The Sag/Swell module monitors applicable phase voltages for temporary
undervoltages and overvoltages (i.e. CBEMA Type 2 and Type 3 disturbances).
Once a disturbance is detected, magnitude and duration data is captured by the
Sag/Swell module, and is passed to a data recording framework.
