SC105 CS I/O to RS-232 Interface 1. General Description FIGURE 1-1. SC105 CS I/O to RS-232 Interface The SC105 (FIGURE 1-1) is used to interface a Campbell Scientific datalogger to any modem that is configured with an RS-232 DCE (Data Communications Equipment) serial port. The SC105 is an intelligent interface that buffers data (1 kB buffer size), allowing many RS-232 data rates, and all CS I/O port modes. Features include: • True RS-232 signal levels. • Power for the SC105 is supplied from the 5 V supply on pin 1 of the datalogger's CS I/O port. The SC105 will use the 5 V supply to power the RS-232 modem if needed. • Two way (interactive) communication. • Supports most RS-232 baud rates. • Supports all CS I/O port modes. The SC105 is frequently used with a short haul modem to communicate across a dedicated line made of two pairs of twisted wire with a shield. Section 3, Setup Menu, describes the details of this application using a short haul modem built by RAD. The SC105 is also commonly used with satellite transmitters, cellular modems, and spread spectrum radios. The SC105 also supports one-way output or printer communication. 1

SC105 CS I/O to RS-232 Interface
The SC105 (FIGURE 1-1) is used to interface a Campbell Scientific datalogger
to any modem that is configured with an RS-232 DCE (Data Communications
Equipment) serial port.
The SC105 is an intelligent interface that buffers data
(1 kB buffer size), allowing many RS-232 data rates, and all CS I/O port
modes.
Features include:
•
True RS-232 signal levels.
•
Power for the SC105 is supplied from the 5 V supply on pin 1 of the
datalogger’s CS I/O port.
The SC105 will use the 5 V supply to power the
RS-232 modem if needed.
•
Two way (interactive) communication.
•
Supports most RS-232 baud rates.
•
Supports all CS I/O port modes.
The SC105 is frequently used with a short haul modem to communicate across
a dedicated line made of two pairs of twisted wire with a shield.
Section 3,
Set-
up Menu
, describes the details of this application using a short haul modem
built by RAD.
The SC105 is also commonly used with satellite transmitters, cellular modems,
and spread spectrum radios.
The SC105 also supports one-way output or printer communication.
