RavenXTV CDMA Sierra Wireless Cellular Modem
c. Select the “Serial” Group, and make sure the “AT Verbose Mode” is
set to “Numeric” for use with the CR10(X), CR510, and CR23X
dataloggers, or “Verbose” for other dataloggers (e.g., CR1000).
If the modem answers but you do not get a connection to the datalogger:
1. Check your connection to the datalogger.
a. An SC932A or SC105 interface is required to connect the modem to a
datalogger’s CS I/O port (Section 4, Configuration). The default
settings for SC105 (OS > 4) can be used with the RavenXTV when
the modem is configured for 115200 baud (baud rate is set by the
template file).
Baud rate of the SC105 must match the baud rate in the modem
(which has to be supported by the datalogger). SC105 settings for use
with the RavenXT are listed below, which are configured using the
DevConfig utility.
SC105 settings for the RavenXT:
CS I/O Mode: SDC Address 7
RS-232 Mode: Modem
Baud Rate: 115.2K or 9600 baud depending on datalogger model
8 data bits, 1 stop bit, no parity
Make sure the modem is connected to the “DCE Device” connector
on the SC932A, or the “Modem” connector on the SC105.
b. A null modem cable is required to connect the modem to a
datalogger’s RS-232 port. No other interface is required.
