5.3.1 SC105 Interface
In order to connect via the CS I/O port of the data logger a serial interface is required.
Generally a SC932A RS-232 interface is supplied, however in some cases the alternate SC105
RS-232 interface may be used due to the customer preference or the requirements of the
system.
The SC105 is a more advanced device than the SC932A as it contains more user-definable
settings which allow the interface between the modem and logger to be specifically
configured and controlled. The following section relates to using the SC105 interface.
In order for the SC105 to work effectively with the SAM3G+ modem, the SC105 default
settings will need to be slightly modified. To change these settings, we recommend using
Campbell Scientific’s Device Configuration Utility, available from
https://www.campbellsci.com/downloads. If desired, configuration changes can also be made
using a terminal emulator package and the SC105’s built in menus.
Figure 5.2 Connection to SC105 using Device Configuration Utility
To configure the SC105 using Device Configuration Utility, first connect the female-female
null modem cable supplied with the SC105 to your PC’s serial port and the Modem connector
on the SC105. Next, provide power to the SC105 by connecting the SC12 cable supplied to
the SC105’s Datalogger connector and the CS I/O port of a datalogger. Once this is done,
open Device Configuration Utility, expand the Peripheral section if available and select
SC105. Check that the Communications Port selected is the one that you have connected to
the SC105, press the green program button on the SC105, then press Connect in Device
Configuration Utility.
