SC932 9-Pin to RS-232-DCE Interface
8
The SC932 leaves the factory with the jumpers set as shown in Figure 4. In this
mode, the SC932 and RAD modem combined will require about 2 mA while
inactive and less than 20 mA while active. When using Campbell Scientific’s
PC208W telecommunications software to communicate through the
SC932/RAD modem, “Setup” the link as a direct connect between the
datalogger and the desired COM port. Start two way communication using the
“Connect” button on the Tool bar and the “Connect” button in the “Connect”
window.
4.2 RAD Modem - One Way
FIGURE 5. One Way Communication
In this mode, the SC932 and RAD modem combined will require about 2 mA
while inactive and less than 20 mA while active.
Use Instruction 96 in the datalogger to output data to a printer or display. The
bit rate, parity, start and stop bits must be the same in the datalogger and the
display/printer. The datalogger sends the data as 8 data bits, no parity, 1 start
bit and 1 stop bit. When using Campbell Scientific’s PC208W
telecommunications software to display “printer” data sent by the datalogger
“Setup” the link as a direct connect between the datalogger and the desired
COM port. Start one way communication using the “Connect” button on the
Tool bar, the “Terminal” tab, and the “Open Port” button in the “Terminal” tab.
Wait for the data to be displayed.
Only one twisted pair is required for one way communication.
Refer to RAD manual for wire connections.
