To access the menus using Hyperterminal, establish a connection between the serial port and
the SC105 using the null-modem cable (included with the SC105). The port settings for this
connection should be 9600-8-N-1.
Press the green programming button on the side of the SC105 and the menus will appear in
the terminal window.
The required settings for the SC105 are:
o CS I/O Mode: The CS I/O interface on the SC105 needs to be set to Modem Enable
to allow the modem to interact correctly with the data logger when data is being
transmitted. This setting is made in the CS I/O menu in the SC105.
o CS I/O Baud Rate: This should be set to 115.2k baud to match the default baud rate
of our data loggers’ CS I/O port.
o RS-232 Mode: This option allows the user to specify what configuration of
handshaking lines will be used on the RS-232 side of the SC105. The required
setting is PC/PDA mode. This will enable the DTR & DTS handshaking lines to be
held high at all times while communication is taking place between the modem and
the data logger.
o Baud Rate: This should be set to 115.2k baud to match the baud rate of the
SAM3G+ modem.
o Power Settings: The ‘Auto Power Down’ mode should be disabled. When Auto
Power Down (APD) mode is enabled, the handshaking lines between the SC105 and
the modem can be disabled to save power. The major advantage of using this setting
is to maintain the modem’s ability to answer circuit switched calls. If the RTS line is
not set with this setting, the modem will not properly receive calls. The extra power
consumption associated with this setting is negligible.
