COM320是一种语音合成modem，向CR800, CR850, CR1000, 或 CR3000 数据采集器添加了语音播报功能。该功能允许用户呼叫数据采集器站点提供关于实时数据或历史数据的语音概要。COM320还可以作为标准modem使用。
>COM320含有1个CS I/O端口，1个电源端子，1个接线端子，和1个RJ-11C插孔。数据采集器通过SC12 或 SC12R-6线缆连接到COM320的CS I/O端口。RJ-11C插孔用于连接带有浪涌保护的固话线。此外，接线端子（GND, RING, TIP）也可用于将COM320通过浪涌保护器连接到固话线。
还需要 数据采集器 - PC通讯，在PC端，运行PC400、LoggerNet或RTDAQ数据采集器支持软件的台式机或笔记本电脑，7026串口线或等效的modem线缆，以及用户提供的兼容Hayes标准的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.
Execution of this download installs the COM320 Operating System on your computer.
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; however, special words or phrases using a real person’s voice can be created for the COM320. Contact Campbell Scientific for a cost estimate for this service.
No. Any communications device can be used to call out by the newer data loggers (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.
