INSIM01 SERIAL INTERFACE MODULE CONFIGURATION
INTRODUCTION
I-E96-417A
B - 3
Jumpers JP3 through JP6 set the RS-232-C handshaking sig-
nals for the diagnostic terminal and computer. Table B-5 con-
tains the settings for jumpers JP3 through JP6. Refer to the
INPCI01 Plant Loop to Computer Interface
instruction man-
ual for details on required handshaking signals. Figure
shows the jumper settings for the available communication
baud rates of the RS-232-C ports on the SIM module. Short the
appropriate set of pins by placing a jumper over them to select
a particular baud rate.
Jumpers JP11 and JP12 set the clear to send (CTS), data set
ready (DSR), and data carrier detect (DCD) handshaking lines.
These lines are not required by the SIM module. Shorting pins
2 and 3 by placing a jumper across them ties these signals to
+12 VDC.
