COM320 Voice Communications Modem WARNING The VoiceSetup SecsOnLine setting is important as it hangs up (auto-disconnects) the modem in case someone hangs up the phone or leaves the phone offhook without pressing star keys for an orderly “goodbye” disconnect. Test the entire program in this regard before deployment to avoid possible lengthy off-hook states disallowing incoming calls, running up a phone bill and draining the station power supply.
COM320 Voice Communications Modem The COM320 ships with an SC12 cable (9-pin to 9-pin) for connecting between the modem CS I/O port and datalogger CS I/O port. NOTE The COM320’s communication port is designed to function with a Campbell Scientific CS I/O port. This is not an RS-232 port. See Appendix E for the CS I/O port description. 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.
COM320 Voice Communications Modem 5.1 Features The voice instructions listed in 5.2 are combined with standard CRBasic instructions to create the code needed for telephone answering, dialing, voicing word strings, voicing data, receiving key presses from the remote phone, and acting upon those key presses. 5.1.1 Callback Callback is the ability of a datalogger/COM320 station to initiate a phone call ‘back’ to a PC running LoggerNet (data mode) or to a telephone (voice mode).
COM320 Voice Communications Modem 5.2 Voice Instructions The Quick Start example voice callback/callin program “BASIC_VOICE_2.CR1” provides a starting point from which to build the features you want. Patterned after the example program in Quick Start, voice instructions can be combined in a variety of ways to provide phone access to datalogger data and for control of datalogger flags/output control ports. 5.2.
COM320 Voice Communications Modem 5.2.4 VoiceNumber The VoiceNumber instruction returns the accumulated touch tone digits that are received prior to the receipt of a # or * key. The example voice callback/callin program uses no VoiceNumber instructions; however, this instruction may be useful for phone transfer of long numbers such as for passwords, etc. 5.2.5 DialVoice The DialVoice instruction is used to define the dialing string for a COM320 voice modem, usually for voice callback.
COM320 Voice Communications Modem 5.2.8 VoicePhrases The VoicePhrases instruction is used to provide a list of phrases for a VoiceSpeak instruction. This instruction allows the VoiceSpeak instruction to output a string from a list of several strings, depending upon some condition in the program. 5.3 Data Callback The COM320 can be put into data mode to accomplish data callback, instructing LoggerNet to do a collection of datalogger data. 5.3.

COM320 Voice Communications Modem with the remote PakBus device identified by the PakBusAddr parameter (LoggerNet server with PakBus address = 4094), the DialSequence code for that datalogger will be executed. DialModem The DialModem instruction is used to send a modem dial string out one of the datalogger's ports. DialModem can be used within DialSequence / EndDialSequence to specify a communication route to be used for a PakBus device.
COM320 Voice Communications Modem For callback collection, the datalogger’s DialSequence instruction changes the COM320 from default voice mode to data mode. The commas create a delay so that the “9” is received by the COM320 during the voice announcement. When the COM320 detects the “9” it disables voice communications and enables data mode for the remainder of that connection.

COM320 Voice Communications Modem 6.5 Connecting to a Surge Protector Campbell Scientific offers two surge protectors (CSI model 4330 and CSI model 6362). The 4330 and 6362 are essentially the same, except the 6362 has hardware for mounting to an enclosure backplate. NOTE The 4330 is also known as the 2374-01. The 4330 and 6362 have a protector element for each line that consists of a heavy-duty-rated, two-element gas tube, an external backup gap assembly, and a switch-grade shorting mechanism.

Troubleshooting COM320 Voice Systems Following are some possible reasons for your COM320 system not working or not working properly. 7.1 No Communications Voice Mode — No voice announcements when you call the station 1) The COM320 is connected to a digital rather than an analog phone line. 2) The COM320 configuration was changed from its default factory settings (see Appendix D).
COM320 Voice Communications Modem 7.2 Communications Problems Voice Mode 1) Can’t get beyond the initial voice announcement a) The security code was not received. Try pressing # again, then xxx# again (where xxx = modem security code). 2) Pressing handset keys sometimes fails to produce the correct response. a) Handset keys not being pressed long enough. b) Key presses (especially # #) were not spaced far enough apart and the station is waiting for the last key (#).

Appendix B. Updating and Configuring the COM320 The COM320 has an internal USB port for connecting the mode to a computer. Connection to a computer is required to install the drivers, download an operating system, change COM320 settings, and retrieve a vocabulary list. NOTE The COM320’s case must be removed to access the USB port (see Section B.1). B.1 Removing the Cover to Access the USB Port 1) Use a Philips screwdriver to remove the five screws on the sides of the COM320. 2) Lift off the case. B.
Appendix B. Updating and Configuring the COM320 4) After some delay, your computer should show a dialog similar to that shown below. Since the driver is obtained from Campbell Scientific, you should select the option No, not this time in the dialog.
Appendix B. Updating and Configuring the COM320 6) In the next dialog, you will need to specify the location where the downloaded driver file was stored. In the example shown, the driver was stored in the c:\download directory. 7) You will get a warning from the operating system indicating that the driver is "unsigned". In order to continue with installation, you need to select the Continue Anyway button.
Appendix B. Updating and Configuring the COM320 8) When the driver installation process has completed, the following final dialog should be shown: B.4 Downloading a New Operating System to the COM320 To download a new operating system to the COM320, follow these steps: 1) You must remove the top cover of the modem to expose the USB port. This is done by first removing the five Phillips head screws on the sides of the COM320. 2) You must also provide a power source (+12VDC) for the modem.
Appendix B. Updating and Configuring the COM320 7) Click the Start button. 8) In the resulting file open dialogue box that appears, select the file that should be sent as the modem's operating system. CAUTION Do not attempt to load any operating system other than that designed for the COM320 modem. 9) The program should now send the operating system to the modem. CAUTION Interrupting this process may corrupt the modem operating system. FIGURE B-1. Send OS Screen in Device Configuration B.
Appendix B. Updating and Configuring the COM320 2) You must also provide a power source (+12VDC) for the modem. This can be done by applying power on the green 12Vand G terminals on the device or plugging the modem into the CS I/O port of a datalogger. 3) Connect the COM320 USB port to one of the USB ports on your computer and wait for the computer operating system to load its device drivers.
Appendix B. Updating and Configuring the COM320 7) Click on the Connect button to connect to the COM320 and enter the settings editor (Figure B-3). FIGURE B-3. Device Configuration Settings Editor CAUTION When doing datalogger to datalogger communications with the COM320, if more than six rings are specified, the datalogger may time out before the modem answers; communication will never be established! Be sure to try the set up locally before installing at a remote location. B.
Appendix B. Updating and Configuring the COM320 3) Launch the Device Configuration Utility and select device type Unknown, the correct PC serial port connected to the COM320, a baud rate of 9600 and press the connect button. 4) By pressing the “V” key you should see a list of words scroll by in the Device Configuration Utility terminal window. If you want to save this list to a file, select the Start Export button and enter a name for the file it will create.
Appendix C. CS I/O 9 Pin Serial Port NOTE The COM320’s CS I/O port is not a standard RS-232 connection. Pin Description The COM320 modem connects to the datalogger using an SC12 cable connected to the datalogger’s CS I/O port. The COM320’s connector configuration is shown in Figure C-1. Table C-1 shows the I/O pin configuration, and gives a brief description of the function of each pin. CS I/O FIGURE C-1.
