>>> [Pager]

This tab allows the user to setup the Dialout and Pager strings to be used when the logger dials a pocket pager via a modem. This occurs when the Pager Alarm is triggered. Older loggers do not have a Pager Dialout facility. This can also be used to send an SMS text message to a cell phone.

Dial Out String

The Dial Out string is the string of characters required to set up the modem and dial the phone number to be paged.

Explanation of the Dial out String in above example
AT - AT command to Modem
S7=1 - Wait Time for Carrier set to 1 second
S8=10 - Pause Time for Dial Delay Modifier (,) set to 10sec
D - Dial
T - DTMF (Tone) Dialing
, - wait for 10sec ( this period was set by S8=10)

Pager String

The Pager string is the string of characters that represents the message to be sent to the Pager once the Dial Out String has been sent.

Explanation of Pager String in above example
1923 - the numeric message to be sent to the pager
# - the message terminator specified by the Pager Service Provider
The square box is a Carriage Return. It was inserted using the Add CR button (see below) The CR is required to terminate the command to the modem.

Add CR (Early Versions of Omnilog)

The Add CR button is used to insert a Carriage Return (Character 13 Decimal) into the Dial Out string or Pager String. The Carriage Return is inserted at the current cursor location. This button is required as pressing the Enter key will just move the cursor to the next field.

Add Ctrl Chr (Version 1.39 and greater)

The Add Ctrl Chr button is used to add various control characters to the Dialout or Message Strings. In earlier versions there was an Add CR button to add a Charage Return to the string but some applications require other control characters. There is now a pull down list of Control Characters that can be added to the strings at the Bottom Right of the Pager Screen. There include NULL, ACK, BELL, BS, LF, CR, NAK, ESC and Ctrl Z

Default

The Default button is used to restore the Dial Out string and Pager String to the default settings. The default settings are setup and can be changed from >>>Tools Options... [Pager]

Clear

The Clear button is used to clear the Dial Out string and Pager String

Test Alarms

The Test Alarms button sends the pager dialout string to test the modem setup. The new strings must be written to the logger before this test is carried out.

Write Pager Alarm Strings to Logger

The Write Pager Alarm Strings to Logger button is used to write newly modified Pager strings to the logger.

Notes on using the Pager Alarm Function with a GSM Modem to send an SMS Text Message to a Cell phone

If the logger is connected to a GSM Cell Modem, the Pager Dialout can be used to send an SMS text message to a cellphone.
The AT command to send a Text Message is AT+CMGS=number<CR>message<Ctrl Z>.
The number must be enclosed in double qoutes.
Example to send a Text Message Via a GSM Cell Modem


Dial Out String
The AT+CMGS= instructs the GSM cell modem to send an SMS message
The "+64210478847" is the phone number of the cell phone to send the message to (note the double quotes)
The square box is a Carriage Return. It was inserted using the Add Ctrl Chr button with the Control Characer pulldown set to CR
Pager String
Browns Bridge Temp>32degC
Is the text message that will be sent to the cell phone
The square box is a Ctrl Z. It was inserted using the Add Ctrl Chr button with the Control Characer pulldown set to Ctrl Z
The Ctrl Z is required to terminate the text message

Notes on using the Pager Alarm Function to Dial a normal Telephone

The Pager Alarm Function can be used to dial a standard telephone or cell phone. If this is done the numbers entered in the Pager String box are heard as DTMF tones when the phone is answered. The 10sec delay caused by the comma after the phone number is dialed and before the message numbers are heard as DTMF tones is a set time independent of when the phone is answered. If it is 15 sec before the phone is answered then no DTMF tones will be heard. For this reason it is recommeneded that further 10sec delays be put into the pager String. For example consider the Dial Out String ATS7=1S8=10DT3853910, and a Pager String of 1919,1919,1919,1919,1919<CR>:
ATS7=1S8=10DT - will set up the logger
3853910 - will dial the phone number
, - will delay for 10sec
1919 - will send a DTMF tones for 1919
, - will delay for 10sec
1919 - will send a DTMF tones for 1919
, - will delay for 10sec
1919 - will send a DTMF tones for 1919
, - will delay for 10sec
1919 - will send a DTMF tones for 1919
, - will delay for 10sec
1919 - will send a DTMF tones for 1919
<CR> - is the Carraige Return that terminates the command to the modem
In this case the last DTMF tones will be sent 50sec after the call is initially made so anyone answering the phone within 50sec of it ringing will hear the tones.
