Access limitation
Printer function
Operation via system
software type AKM
If a PC with system software type AKM is connected to the system, it will be possible to:
- perform all settings from the PC
- receive alarms on the PC
- connect a printer to the PC where printouts will be made of all alarms
AKA 245 are protected against inadvertent settings and changes of parameters from AKA 21. This is
done by means of access limi tation dis tributed on three levels:
1) Normal “Daily user level”
2) Extended “Engineers level”
3) Service “Service level”
The level limits can be changed in the unit (see section “Settings”).
When the gateway is used in conjunction with system software type AKM, a password function may be
used. This function will block settings when the system is operated via the telephone network and the
password is not known.
For the sake of users of AKM it is however permitted to read and set a few functions. However, access
will not be given to important functions like router lines, upload functions and ID-codes.
The password function must be initiated with system software type AKM.
On AKA 245 there is one way only of operating the printer function.
By activating input DI 1, the gateways internal line counter is zero-set. In this way it is possible to keep
a check on the printer paper perforation.
DI 1 is activated when the printer is switched on, and the printing head is placed in start position on
the fi rst writing line (top of form).
Re setup, installation, insertion of paper in the printer etc., reference is made to the printer’s own
manual.
