5 ComuCont Dual-core
The functionality of the WaveCom WMOi3 Engine is extended via the ComuCont Dual-
core. The core consists of a 8051 processor, an internal clock buffered via Goldcap, an
EEPROM for the storage of the parameters and a RAM of 32 KB to buffer the overflow
during data transmission to the control station.
5.1 Information on operation
The clock-module is buffered via a GoldCap. The parameters are saved on an EEPROM
and are independant on buffering. During the initial installation or in case of long-term
net-off (long-term storage) the ComuCont Dual may indicate a default during
parameterization or at the clock-module. These defaults are removed by parameterization
or synchronization (also see 4. Installation).
Further defaults are registered in relation to the release (PIN-input) of the radio-module.
Defaults are indicated via blinking of the two upper LEDs. By readout of the device via the
parameterization-software PARACOM, defaults may be displayed in plain text.
5.1.1 Starting the ComuCont Dual
When power is applied upon, primarily the Hardware is initialized and checked on
defaults. At the same time, the radio-module is started and initialized. Then the SIM-card
is checked on its status, i.e. queried on its access-code. Hereby the following options are
differentiated:
1. The PIN-number is deactivated in the card
Also if a PIN was parameterized, no PIN-number is transferred to the card.
2. The card asks for the PIN-nummer
If a PIN-number had been parameterized, it will be transferred up to twice to the card . If
this twice does not result in a positive acknowledgement, the ComuCont Dual is set on
default (LED2 and 3 blink). Now, the PIN-number may again be parameterized correctly.
However, if it is wrong again, the card will disable and may only be activated by entering
the PUK (NOTE!! At each restart or each parameterization, the PIN will be transferred
twice. I.e. at this twice transmission the PIN will be disabled!).
3. The card asks for the PUK-number or does not response
The device is set on default (LED2 and 3 blink). The PIN-number is no longer transferred
to the card. Thus, only 1PUK-trail (of 10) is spend at maximum. The card may only be
enabled manually by entering the PUK (command AT+CPIN=PUK-number, new PIN
CR).
The login into the radio-net results automatically. If the ComuCont Dual must not be
reachable, this automatic will be deactivated.
Initialization and checking may take up some time. Therefore, the device is only reachable
serially or via the radio-net after several seconds.
5.1.2 Initializing of the radio-module
Initialization, i.e. a reset of the radio-module is implemented at the following times:
1. After net-on
2. After parameterization
3. After link via the radio path
4. In parameterized time intervall (since the last initialization)
5. If the radio-module does no longer response serially
5.1.3 Field strength display
Approx. every 3 seconds, signal-field strength is queried and displayed via LEDs 2 and 3 (see
3.6.2 Function of the LED’s). If data are transferred, however, this query is disabled (at
minimum for 30 seconds).
