Overview
SC532A CS I/O Peripheral to RS-232 Interface
The SC532A interface enables communications between a PC and a Campbell Scientific 9-pin peripheral by providing power and converting the peripheral’s logic levels to the RS-232 levels required by the computer.
Technical Description
The SC532A is required to:
- Connect a PC to the RF500M Radio Modem’s CS I/O port instead of its RS-232 port.
- Change the COM200-series phone modem’s settings
- Communicate with an MD9 network
- Transfer programs and data to a SM4M/SM16M storage module (retired)
The SC532A replaced our SC532.
Benefits
- Enables communications between a PC and some Campbell Scientific 9-pin peripherals
- Provides power and converts the peripheral's logic levels to RS-232 levels
