The connections and significance of the LED’s are labelled to prevent errors.
Before starting up the device, the SIM cards must be inserted into the provided
holders. Two 3V SIM cards are required for full channel availability, but usage with
one SIM card is possible.
To insert the SIM cards in the device, first push in the round yellow button next to the
cardholder with a blunt, thin tool and then remove the cardholder. The SIM card is
then placed in the cardholder and inserted into the card reader together with its
holder. The contact area of the cardholder must be facing the rear of the device.
Attention: When pushing in the card, ensure that it does not fall out of the cardholder
and that the card is correctly inserted in the cardholder guides. The device requires
3V SIM cards for operation!
3.1 Starting up the device
The SIM cards should be inserted into their reader slot first. Then the necessary
cables are connected: Connection to the TC system as NT or TE, a connection to the
PC's USB port on which the coMsat.exe application is installed, and finally the
antenna cables.
Note 1: The GSM/UMTS modules used in the coM.sat ISDN Basic UMTS for
communication via the GSM/UMTS network operate with an internal voltage of 3V.
Therefore, for proper operation, SIM cards that can still operate with a working
voltage of 3V must be used. All new SIM cards usually fulfil this requirement. If older
cards (designed for a voltage of 5V) are used, the device possibly cannot log into the
network - despite input of the correct PIN - because the SIMs cannot operate
correctly at a voltage they weren't designed for.
Note 2: When looking at the front of the device, the left-hand SIM card is assigned to
channel 1 and the right-hand card to channel 2.
Once it has been installed, the device can be switched on by inserting the power
jack. This is indicated by the green LED which is labelled “Power“.
All the relevant parameters in the device are deleted in the factory before delivering
the coM.sat ISDN Basic UMTS, so that it must be set for the individual installation.
Therefore, when installing the TA for the first time, it must be configured using the
coMsat.exe application. To do this, a USB data link must be established between the
coM.sat ISDN Basic UMTS and the PC on which the application is installed.
