COM210 Telephone Modem
1. Introduction
1.1 General Description
The COM210 Modem is a 9600 baud phone modem employing the Hayes AT
command set. Its primary use is as a remote site phone modem connected to a
CSI datalogger. The modem is powered and enabled by the battery-powered
datalogger. When not active, the COM210 draws less than 120 µA from the
datalogger’s 12 VDC output. The COM210 is a drop in replacement for the
COM200.
The COM210 is connected to a CSI datalogger by using a 9-pin subminiature
D connector cable. This is the same 9-pin CS I/O connection common to all
Campbell Scientific dataloggers (except the CR200 series). This is not an RS232 connection. Appendix B describes the configuration of this connector.
The COM210 can be used as an originate modem at the datalogger site. For
Edlog dataloggers (e.g., CR510, CR10X, CR23X), use Instruction 97 to
program the datalogger to originate a call to the computer; refer to your
datalogger manual for a detailed description of Instruction 97. CRBasic
dataloggers (e.g., CR1000, CR3000) use the Dial Sequence and Dial Modem
instructions.
The COM210 features a built-in speaker to allow monitoring of calling and
connection operations. See Appendix A.3 for the Hayes AT commands that
affect the speaker on/off and volume settings.

1.2 Computer Requirements
A Hayes-compatible modem is used at the computer site with Campbell
Scientific computer software to call the datalogger attached to the COM210.
The computer’s modem must be configured to the proper settings using the
modem initialization strings listed in the software programs.

3. Installation
3.1 Connecting to Datalogger
• Supply requirements: 12 VDC regulated power supply
• Internally switches 12 VDC external power minimizing current drain
• Logic levels: below 1.5 V inputs a low state and above 3.5 V inputs a
high state. A low voltage level on the TX data input (pin 9) and RX data
output (pin 4) represents a mark
• Operational temperature: -25
temperature range of -55°C to +85°C is available at time of purchase.)
• Size: 5.2” x 1.7” x 3.6” // 13.1 x 4.3 x 9.2 cm
• Weight: 0.75 lbs // 0.34 kg
The COM210 is designed to be used with standard analog telephone lines. It
will not work with a digital telephone line. Connection to telephone-companyprovided coin service (central office implemented systems) is prohibited.
Connection to party line service is subject to state tariffs.

Connect the cable from the telephone RJ11C jack to the modem as shown in
Figure 3. If the telephone company has not installed surge protection in the
telephone line (no RJ11C jack), one must install surge protection (CSI item
number 6362 or 4330) and connect the ring and tip terminal blocks as shown
in Figure 2.
Current Campbell Scientific dataloggers provide 12 VDC to the COM210 via
the SC12 cable (Figure 2). Older dataloggers do not provide 12 VDC on the
datalogger's CS I/O 9 pin connector. When used with the older dataloggers
listed in Table1, 12 VDC and ground need to be connected via the green power
connector on the side of the COM210 (see Figure 3).

3.2 Connecting to Earth Ground
Connect the green 14 awg grounding wire (provided with the COM210) to the
grounding terminal (GND) on the COM210 and to the enclosure’s earth
ground connection. If the site does not have a grounded enclosure, then
connect the ground wire directly to an earth ground connection. The
datalogger ground should also be tied to the earth ground.

CAUTION
The modem must be grounded for its transient protection
to work.
3.3 Telephone to MD485 or Telephone to RF Systems
Telephone to MD485 or telephone to radio systems can be utilized for
communicating with multiple dataloggers through one telephone line. Nothing
additional or special is required for the telephone part of the link. See the
MD485 or RF Manuals for complete information on their special requirements.
3.4 Telephone Service
The goal of the telephone company is to provide you with the best service it
can. In order to do this, it may occasionally be necessary for them to 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 will provide this information upon
request. If the telephone company requests information concerning the
equipment which you have connected to your telephone line, the FCC
registration number and the ringer equivalence number (REN) of the COM210
are listed on its label. Additional technical information from the FCC and IC on
the COM210 is available in Appendix D and E, respectively.
