CallInVoice Subroutine This subroutine contains the code pointed to by VoiceBeg / EndVoice that is to execute after a call in occurs.
COM310 Voice Communications Modem 4.2 Surge Suppressor If the phone company does not provide surge protection at the datalogger site, you will need to install some. CSI offers surge protectors in two forms. Item # 6362 is a surge protector with environmental enclosure mounting hardware. Item # 4330 is the surge protector with no mounting hardware (see Section 6.6). 4.3 Voice Capable Dataloggers There are several Campbell Scientific dataloggers that are capable of voice communications.
COM310 Voice Communications Modem NOTE The COM310 must connect to an analog phone line. Some office environment PBX phone lines are digital and don’t interface to an analog modem such as the COM310. Of course, any phone may be used to call in to or receive callbacks from the COM310. A touch-tone phone is necessary for input. 5. Datalogger Voice Programming The voice code for the CR1000 and other voice capable CRBasic dataloggers is integrated with the main program.
COM310 Voice Communications Modem 5.1.1.2 Voice Callback The COM310 gives you the ability to do voice callbacks. You can program a station to call one or more telephone numbers and announce an alarm message when conditions you specify are met. You can input multiple phone numbers to increase the probability that someone will receive the message.
COM310 Voice Communications Modem The VoiceSpeak code might look like this: TC_1 = Public.AirTemp(1,1) VoiceSpeak ("THE AIR TEMPERATURE WAS" + TC_1 + "DEGREES", 0) 5.2 Native PakBus Dataloggers The CR1000 and other voice capable CRBasic dataloggers can be programmed to provide the features available in the Edlog dataloggers, and most any other feature you can imagine. The Quick Start example voice callback/callin program “BASIC_VOICE_2.
COM310 Voice Communications Modem announced menu; however, the user can respond by pressing a key in the middle of an announcement. If doing concurrent communications (via multiple communication peripherals) with your datalogger it is recommended that the VoiceKey timeout be extended to over 5 seconds. VoiceSetup’s UseTimeout parameter determines whether or not the datalogger will hang up the COM310 after the timeout in the VoiceKey instruction expires. 5.2.1.
COM310 Voice Communications Modem The CallOut parameter is a Boolean value that indicates the COM310 mode. When the value returned in this parameter is True the datalogger has called out. When the value is False the datalogger has received an incoming call. If the same ASCII character is used for HangUpKey and ExitSubKey, the datalogger will exit a subroutine if it is in one, otherwise, it will hang up the COM310.

COM310 Voice Communications Modem 5.2.2.1 Data Callback Instructions The following instructions are used to program a data callback. DialSequence/EndDialSequence The DialSequence/EndDialSequence instructions are used to define the code necessary to route packets to a PakBus datalogger.
COM310 Voice Communications Modem tutorial is a more advanced tutorial for setting up voice callback. Example program files are included for use in the tutorials. If you’ve had little experience in creating/editing datalogger programs in Edlog, we suggest that you begin with Quick Start (Section 3) and the basic LoggerTalk tutorial, referring to the Help system with any questions you might have. For a guide to interpreting the voice codes that LoggerTalk appends to a *.
COM310 Voice Communications Modem 5.3.6 Voice Callback LoggerTalk can program a voice callback when associated with a *.dld file that includes a P97 with Parameter 1 = “31” for mixed-array dataloggers or “39” for PakBus dataloggers (see Section 5.1.1.2). LoggerTalk allows you to input multiple phone numbers to increase the probability that the alarm message will get through. If the first phone is not ‘picked up’ then the second number is dialed.
COM310 Voice Communications Modem In LoggerNet a comma represents a 1 second delay. You may need to adjust the number of commas so that the “9” occurs during the voice announcement, depending upon the length of time required to establish the connection with the modem. For information on creating an Edlog datalogger program and downloading it to the COM310 station, refer to the Basic Tutorial in LoggerTalk help. 6. Hardware Installation 6.
COM310 Voice Communications Modem FIGURE 3. COM310 / CR1000 Using Surge Protection Device (where there’s no available Standard RJ11 Connection) 6.2 Powering the COM310 Modem Newer Campbell Scientific dataloggers provide 12 VDC on CS I/O connector pin 8 for powering peripherals such as the COM310. The alternative, if you have a dataloggers/wiring panel lacking 12 VDC on pin 8, is to wire the green connector on the side of the COM310 to the datalogger +12 VDC and power ground terminals (refer to Figure 4).
COM310 Voice Communications Modem 6.3 Grounding the COM310 System Connect the green 14 AWG grounding wire (provided with the COM310) to the GND terminal on the COM310 and to the station enclosure’s earth ground connection. It is important that you connect the COM310 and datalogger directly to a high quality earth ground. Read the datalogger manual section on GROUNDING for details on creating such an earth ground.
COM310 Voice Communications Modem 6.4 Telephone Service Telephone companies occasionally make changes in their equipment, operations, or procedures. If you have any questions about your telephone line, such as how many pieces of equipment you can connect to it, the telephone company should be able to furnish this information upon request.
COM310 Voice Communications Modem Figures 5 and 6 show the wiring for connecting the surge suppressor. Color coding of wires may vary. The important consideration is to follow TIP all the way through and RING all the way through. Getting wires crossed typically does not damage anything. The phone line just will not work until the wires are straightened out. CAUTION Phone wires are live, typically with low voltage (24 Vdc).

Troubleshooting COM310 Voice Systems Following are some possible reasons for your COM310 system not working or not working properly. 7.1 No Communications Voice Mode — No voice announcements when you call the station 1) The COM310 not getting 12V power due to an older datalogger/wiring panel that does not provide 12V on CS I/O pin 8. 2) The COM310 is connected to a digital rather than an analog phone line.
COM310 Voice Communications Modem 6) LoggerNet Setup configured for the wrong PC modem. 7) LoggerNet configured for a baud rate the station cannot handle (try 9600). 8) COM310 configuration was changed from its default factory settings (see Appendix D). 7.2 Communications Problems Voice Mode 1) Can’t get beyond the initial voice announcement a) Security mode is enabled (Edlog datalogger). b) Commercial mode is enabled (Edlog datalogger). c) Datalogger is running a *.
Appendix A. Theory of Operation The COM310 modem is used to transmit data over bandwidth-limited channels such as telephone lines by modulating audio tones, using Phase Shift Keying (PSK) at 9600 or 1200 baud and Frequency Shift Keying (FSK) at 300 baud. The COM310 has four connectors: 1. 2. 3. 4. RJ11 – telephone line Orange Tip, Ring, GND – alternate telephone line and EARTH GROUND CS I/O – datalogger serial comms and 12 VDC power if more recent wiring panel (see Section 6.
