Scientific dataloggers (except the CR200 series). This is not an RS-232 connection. Appendix B describes the CS I/O interface. The COM220 can be used as an originate modem at the datalogger site. For non-Pakbus dataloggers (e.g., CR510, CR10X, CR23X), and for older PakBus dataloggers (e.g. -

Weight: 0.35 lbs (0.16 kg) 3. Installation The COM220 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. -

When using a PakBus network with a datalogger configured as a router, the COM220 can be set for SDC7 and the radio for SDC8, or vice versa.

Modem Settings The COM220 comes from the factory with the appropriate settings for PakBus dataloggers (e.g., CR8x0, CR1000, CR3000, CR10XPB, CR23XPB). It is programmed to answer a call as soon as a call is detected. -

For example, the COM220 is sharing a line with people at an office. It can be programmed to only answer after the third ring. If the PC calls when the office is closed and no one answers the phone after three rings, the datalogger will pick it up. - Page 12 Instructions for setting the COM220’s ME baud rate are found in Appendix A.1. 5) If the COM220 is set for Modem Enable (DIP switch 1 open) and you are unable to connect to the datalogger, try setting the datalogger BaudrateME to a negative number (e.g.
- Page 13 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. 12) Verify the COM220 is receiving 12 VDC. If the COM220 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?

Page 22: Dialmodem Example (For Cr1000
End Program A.4.2 DialModem Example (for CR1000) The program below does 2-minute callbacks via the COM220 configured for SDC7. DialModem is set equal to a variable, so that the success/failure result can be used by the EndDialSequence instruction. If the call fails, the link will be terminated at the EndDialSequence instruction. -

Edit instruction 13 with your PC’s (LoggerNet’s) phone number. Remember to set COM220 DIP switch 5 to “closed”, switch 1 open for Modem Enable mode, and switches 3 and 4 open for 9600 baud. The callback ID in this example is 222.

A.4.4 Example Programs for Data-Callbacks via a CR1000 Datalogger Router. In order to do data callbacks via a datalogger router with COM220 and RF401s or MD485s, they must all be configured to communicate with one another. In addition, two programs are necessary: one for the datalogger router and one for the remote datalogger. - Page 26 Sample (1,PanelTemperature,FP2) EndTable DialSequence (4094) StaticRoute(ComSDC8,4094,4094) DialSuccess = DialModem (ComSDC8,9600,"5551212","") ‘ Param 4 = "" allows CR1000 to accept all possible COM220 responses ‘ DialSuccess: -1 means successful, 0 means failure.
