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 RS-

232 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

The COM210 is designed to be used with standard analog telephone lines. It

will not work with a digital telephone line. Connection to telephone-company-

provided coin service (central office implemented systems) is prohibited.

Connection to party line service is subject to state tariffs.

3.1 Connecting to Datalogger

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.

COM210 Telephone Modem

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.

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.

4. Troubleshooting

When the Campbell Scientific software cannot establish a link to the remote

datalogger that is connected to the COM210, check the following:

1) Verify the modem initialization settings have been changed for the

specific calling modem on the computer. See software manual and/or

help screens for more information.

2) Verify nothing else is using the same COM port on the computer. Even if

a program is minimized in windows, it may have a lock on the COM port.

Some notebook computers do not automatically activate the COM ports.

Verify the COM port you are using is activated.

3) The Campbell Scientific software will display an activity of

communication as the link is being established. Assuming the above

items are O.K., the software should display in the activity window/screen

something such as “ATDT#######”. Where the #### is the telephone

number listed in the dialing path of the software for the datalogger you

are trying to call.

The local modem attached to the computer will respond back to the

computer with result codes showing how the call is progressing. These

result codes can be either numeric (0, 1, 2, etc.) or "verbose" ("OK",

"CONNECT", "RING", etc.). Prior to PC208W 3.0, our software

expected numeric result codes. PC208W 3.x and LoggerNet uses

"verbose" result codes to determine call progress. The V command is

used to select between numeric or verbose result codes. Depending on

the version of PC208W being used, the initialization string for the modem

may need to be changed for the appropriate form of result codes. The

result code returned may indicate why the call is unsuccessful. Appendix

A has a list of possible result codes.

4) Can you attach a normal analog telephone to the line and make a call out?

If not, contact your local telephone company. If you can make a call out

but the connection is poor or faint, contact your local telephone company.

5) Verify the COM210 is receiving 12 VDC. If the COM210 is receiving 12

VDC from a separate power supply instead of the datalogger, is the

ground of the separate power supply connected to the datalogger’s

ground?

6) Verify the COM210 is the only Modem Enable device connected to the

datalogger. Other common Campbell Scientific modem enable devices

are the SC32B, some RF modems, and the MD485.

7) Verify the datalogger is turned on.
