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 

µ

A 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.
