Overview
To get the same functionality as the COM210A, order the -AU option for the COM220.
The COM210A enabled communications between a computer and a Campbell data logger via an Australian public switched telephone network. A Hayes-compatible modem was required at the base-station computer while a COM210A was connected to the data logger at the field site. The COM210A's wide operating temperature range and minimal power requirements made it ideal for use at remote sites.

Detailed Description
To get the same functionality as the COM210A, order the -AU option for the COM220.
Note
Historically, the 10704 Power Adapter was available for connecting the COM210A to the CR500 with s/n 1764 or lower, and the CR10 with the silver or 8032 black wiring panel. The adapter applied a constant 12 V to the COM210A's serial I/O. This power adapter is no longer available.

| CR510 (retired) | Not compatible with the CR510's silver or 8032 black wiring panel. Originally the 10704 Power Adapter was used to connect the COM210A to these wiring panels. The 10704 adapter is no longer available. | |
| CR800 (retired) | ||
| CR850 (retired) | ||
| CR9000 (retired) | Although the CR9000 is compatible, the COM210A does not support its fastest communication rates, and is therefore not practical for most of its applications. | |
| CR9000X (retired) | Although the CR9000X is compatible, the COM210A does not support its fastest communication rates, and is therefore not practical for most of its applications. |
Additional Compatibility Information
Power Considerations
The COM210A consumed 120 microAmps quiescent, 160 mA active (max). The data logger's power supply was sufficient for most applications.
Cabling
Data Logger-to-COM210A
An SC12 cable was provided for this purpose.
Phone Line-to-COM210A
Typically, a length of phone line was run from the telephone company's junction box to the COM210A's surge protector, and then to the Ground, Tip, and Ring terminals on the COM210A. Alternately, if adequate surge protection was provided by the telephone company and the junction box supports it, a length of telephone wire with RJ11C connectors (#2365) could be run directly from the junction box to the socket on the COM210A.
Surge Protection
If the local telephone company did not provide surge protection, either the 6362 or 4330 surge protector needed to be used. See "Ordering Info" tab for more information.
Enclosures
The COM210A required a desiccated, non-condensing environment; a Campbell Scientific enclosure was recommended. Grommets and screws were provided to attach the COM210A to the backplate of our enclosures.
Software
LoggerNet and PC400 software are compatible with the COM210A. Both of these software packages provide automated error-checking or user-initiated contacts. LoggerNet also supports scheduled contact times. Our software can run unattended allowing the user to take advantage of lower off-hour telephone rates.
