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.Read More

The SC532A is typically powered by the 15966 Wall Charger; access to 120 Vac is required. Campbell Scientific offers the 14020 and 14291 field cables for remote sites lacking 120 Vac. The 15966 Wall Charger, 14020 Field Cable, and 14291 Field Cable are ordered separately as Common Accessories (see Ordering Info).
An SC12 cable and a 10873 DB9-to-DB9 serial cable are provided with the SC532A. The SC12 cable is for connecting a peripheral to the interface, and the 10873 cable is for connecting the interface to a computer 9-pin serial port. Alternately, the longer SC12R-6 cable can be used for peripheral connections. Computers with only a 25-pin serial port require a DB9-to- DB25 serial cable such as the 7026.
