| RTS Trailing Defines the delay from the RTU is transmitting the last character to deactivating RTS. Retry count Defines the number of retries which should be made to the same telephone number before giving up or continuing to the next number, if the call is not successful. Default value: 3, Range: 0 .. 10. Max comm cnt. Defines the number of times the input and output will be read and written before the module makes a hang-up. If Max Com Count=256 the PC is responsible for correct hang-up. This option should normally not be changed. Subs. to try. Defines the number of subscribers to try after being through the number of retries on the first number in the list of phone numbers. If the value is set to 3, it will try number 1, 2 and 3 in the phone no list. Default value: 1, Range 1-10. Redial delay. Defines the delay from an unsuccessful attempt to dial to a new attempt to establish connection. Default value: 90 sec, Range: 2-120 sec. Tel. no. The maximum number of telephone numbers stored in RTU is 30, the maximum length is 20 characters. The telephone numbers can although include some special characters to control the dialling function of the modem. Modem init. The modem initialisation string has a maximum length of 60 characters. This string contains the configuration data for the connected modem. It will be sent cyclic to the modem and every time a connection is established by the RTU. Default value: ATV0E0&C1S0 PIN code. If GSM modem is used and PIN code is required for the SIM card, the PIN code must be entered here. Be careful to enter the right PIN code - if not, the three normal attempts will quickly be used up and a PUK code is required to re-open the SIM card again. Use a normal mobile telephone to change PIN code parameters and enter PUK codes. Default: blank Modem Reinit. Defined the time in minutes between cyclic re-initialisation of the modem. If the modem of some reason is reset and the required modem settings not has been save in the modem flash, the modem will start up with its default settings. With this option you can make sure that the modem is initialised periodically. Default value: 0 min, range 0-999min. Dial back Enable or disable the dial back function. User User defined value. Constant value can be used in B-CON application / IEC870 Date/Time Real time clock adjustment. The actual time in the module can be monitored and adjusted either by entering the time or by copying the PC clock to the module. |
