SC532A 9-Pin Peripheral to 9-Pin RS232
Interface
1. Function
The SC532A Peripheral Interface connects an IBM
®
PC compatible computer,
with appropriate software, to certain Campbell Scientific datalogger
peripherals including phone modems (COM200, COM210, COM220), storage
modules (SM4M/16M, SM192/716), MD9 multi-drop interface, and Seimac
SCD/Argos satellite transmitter.
Like the SC532, the SC532A supplies 5 VDC on the PERIPHERAL connector
(pin 1) to power 5V peripherals like the SM16M. The SC532A also supplies
12 VDC (on pin 8) to power 12V peripherals such as the COM220, high-speed
modems, and certain radios.
The SC532A has an internal jumper that selects either “SC532” or “PROG”
mode. PROGRAM mode is for configuring the Seimac SCD/Argos satellite
transmitter. The factory setting is “SC532” which is appropriate for most
applications. The case can be opened by twisting a 1/8 inch (3 mm) standard
screwdriver in the four seam slots.
2. Physical Description
An SC12 and a 10873 cable are shipped with the SC532A. The SC12 cable
connects the SC532A 9-pin female D-Sub labeled “PERIPHERAL” to your
CSI peripheral. The 10873 cable connects a PC COM port to the other 9-pin
connector labeled “PC.”
The SC532A is typically powered by the 15966 wall charger (purchased
separately). This wall charger supplies 12VDC @ 800 mA which is sufficient
for any listed peripheral. The power jack on the SC532A allows convenient
wall charger replacement. If only 5V peripherals are used, an AC adapter
outputting just 6 VDC with enough current capability and having the correct
barrel connector size and polarity will do (see Tables 1 and 2).
The 14020 and 14291 field cables are available (see Portable Battery Power
section) for remote sites lacking 120 VAC. The 14020 and 14291 field cables
are purchased separately.
