Connecting a Personal Computer
NOTICE
S&C does not recommend removing the S&C Over-
current Control from its enclosure for workbench
programming . The Overcurrent Control is in a submers-
ible enclosure . Opening the enclosure may damage the
sealing gasket . Contact your local S&C Sales Office for
details .
A data port for communications is provided at the top of
the enclosure that houses the overcurrent control. This
data port, which is connected to the electronics module
inside the enclosure, cannot draw power from the control
and must be powered from an external source while in
use. When the data port is in use, the power­connection
points (Pins 1 and 4) power the control. The allowable
voltage range is 4 – 5 Vdc, and the power consumption is
1.8 W nominal, 2.2 W maximum.
Adapter cables are available from S&C (see Instruction
Sheet 695­515A) for connecting the control to a user­ furnished
personal computer in the field. These cables provide for both
communications and power.
For Microsoft Windows® users, no special software is
required to commu nicate with the control. The user interface
is menu driven within the control. Use the HyperTerminal
program provided with Microsoft Windows or other
terminal emulator program to set or interrogate the control.
Microsoft Windows Vista™, Windows
® 7, and Windows ® 8
users will have to install a terminal emulator program. See
Appendix C for further instructions.
