The COM320 is a voice-synthesizer modem that adds speech capability to a CR800, CR850, CR1000, or CR3000 data logger. This capability allows the user to call a site for a spoken summary of real-time or historical data. The COM320 can also act as a standard modem.Read More
The COM320 has a CS I/O port, power terminals, screw terminals, and an RJ-11C jack. The datalogger connects with the CS I/O port via an SC12 or SC12R-6 cable. The RJ-11C jack is for attaching a surge-protected telephone line. Alternatively, the screw terminals (GND, RING, TIP) can be used to connect the COM320 with a phone line via a surge protector.
The COM320 has a standard word list (see document at right). Campbell Scientific may eventually add more words to the standard list. Customer-requested words for specific applications can also be included; consult the factory for details. The COM320’s sentences are programmed using CRBasic code.
More detailed information about the required equipment is included under the Configuration tab.
Datalogger-to-computer communication also requires, at the computer site, a PC or laptop running PC400, LoggerNet, or RTDAQ datalogger support soft ware, 7026 serial cable or equivalent modem cable, and a user-supplied Hayes-compatible modem.

The COM320’s “sentences” are programmed using CRBasic code, which is included in PC400 and LoggerNet software. Both of these software packages support automated error-checking or user-initiated contacts.
The COM320 must connect to an analog phone line. Some office environment PBX phone lines are digital and don’t interface to this analog modem. Of course, any phone may be used to call in to or receive callbacks from the COM320. A touch-tone phone is necessary for input or to navigate through the COM320’s menu system.
Typically, a length of phone line is run from the telephone company's junction box to the COM320s surge protector, and then to the Ground, Tip, and Ring terminals on the COM320. Alternately, if adequate surge protection is provided by the telephone company and the junction box supports it, a length of telephone wire with RJ11C connectors (#2365) can be run directly from the junction box to the socket on the COM320.
If the local telephone company does not provide surge protection, either the 6362 or 4330 surge protector should be used. See "Ordering Info" tab for more information.
The COM320 requires a desiccated, non-condensing environment; a Campbell Scientific enclosure is recommended. Grommets and screws are provided to attach the COM320 to the backplate of our enclosures.

Note: The Device Configuration Utility is used to upload the included operating system to the datalogger. Requires a USB cable.
Windows USB driver for the COM320 are distributed with the Device Configuration Utililty. In the Device Configuration Utility, click on the link "install the device driver for the COM320" in the main body of text for the COM320.
Note: Device Configuration Utility 2.08 or newer is required to install drives and configure the COM320.

No. Any communications device can be used to call out by the newer dataloggers (except the CR200X-series), but the type of communications device used determines what type of information can be sent. The COM320 can be used to call out with a voice or to send data to LoggerNet.
Yes. By configuring the NL120 as a CSDC device, both the NL120 and COM320 can share the same CS I/O port. The CR1000 and CR3000 are capable of multi-threading, so the NL120 and COM320 can run in parallel. For more information, refer to the NL120 Ethernet Module Instruction Manual.
