Remote Operation (Continued)
The set of allowed commands is divided into group and individual.
The Meter is provided with two levels of access: 1st level of access
"user", and 2nd level of access "administrator". For each access
level, a separate password of six characters (six bytes) is allowed.
For any discrepancy between the meter password/address and the
password/address specified in the command, the command will be
interpreted as wrong and will be rejected by the Meter. In case of
incorrect entry of the password three times the Meter locks the
recording channel for 30 minutes. Session lock time is
programmable through available interfaces.
Each Meter is given the following default passwords and addresses:
- The password of the first level:
FF FF FF FF FF FF (255 255 255 255 255 255);
- The password of the second level:
FF FF FF FF FF FF (255 255 255 255 255 255);
- Exchange rate 9600/8N/1;
- The Meter address is 255 or the last three digits of the serial
number are less than 255,
- The passwords and addresses can only be changed via a serial
interface.
When operating Meters after changing passwords and / or
addresses, pay special attention to the preservation (memorization)
of the latter. Recovery is possible only through the violation of the
Meter seal.
Measures to Prevent
Unauthorized Access
In addition to password protection, there is a hardware jumper for
protection calibration factors of the Meter. Access to calibration
factors is possible only with violation of the Meter seal.
