This dialog is used to configure the GSM parameters of the connected RTCU device.
Each page handles a different part of the configuration.
Setup page
SIM card reader
This option sets the selected SIM card reader on a device with multiple SIM card readers. This is the same as the VPL function gsmSelectSIM.
Antenna
This option sets the selected GSM antenna to use on a device with switchable antennas. This is the same as the VPL function gsmSetAntennaMode.
PIN code page
By using this page, it is possible to enter the PIN code that the RTCU device must use in order to activate the GSM module. If the PIN code is disabled on the SIM Card, the PIN code field must be blank. Please note that this dialog is just for entering the PIN code that has been assigned to the SIM Card. It is under no circumstances used for changing this code. This would have to be done from a "normal" mobile phone or with the gsmSimSetPIN function. If the correct PIN code is not entered here, the RTCU device be unable to connect to the GSM network.
CSD Page
Using this page, it is possible to view and modify the list of callers that are allowed to create a CSD session with the connected RTCU device. Please note that this list is ONLY used when a data call is issued to an RTCU and NOT when a voice call or an SMS message is initiated to a device. If the "Allow no sessions" is enabled, no callers are allowed at all. The contents of all the eight number fields will, however, be preserved.
