1 The factory set Unit ID for COM1 is based on the serial number of the meter, using the last four
numbers before the dash. For example, if the serial number is PA-0009B263-01, the Unit ID is set in
the factory to 9263. After a factory reset, the unit ID number will default to 100.
2 If you have the internal modem order option, the modem shares COM3 with the IRDA optical port.
The modem is factory configured to answer in the number of rings specified by Answer HR Rings (the
Non-Answer HR Rings value is ignored by default). The modem initialization string (
Modem Init ) can
only be altered via software communications.
Refer to the online ION Programmer’s Reference for complete details about all the
setup registers in the Communications module.
Modem Initialization String
The setup register labeled ModemInit is available for ION 7500 and ION 7600
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.
Refer to the Modem AT Commands technical note for information regarding your
internal modem, including details on customizing the modem’s registers.
N OTE
The ModemInit string is automatically sent to the internal modem when the ModemInit setup register is
changed, when the meter is powered up, and when the baud rate of the modem’s Communications
module is changed.
Communications Protocols
By default, all COM ports are configured to use the ION protocol. If you want to
make use of Modbus RTU, DNP, or GPS system, you need to configure the Protocol
setup register for the Communications module that controls the port you want to
use. However, the F
ACTORY protocol is reserved for the use by Technical Service
Engineers.
