Resetting the KAM’98 through the DB-25 connector.
EXT-IN via pin 25 of the DB-25 connector may be configured to allow you to
perform a soft reset. This is accomplished by connecting J2 center pin and pin 2,
J1 center pin and pin 1. A momentary contact to ground will cause a soft reset.
Hardware handshaking with DSR and DTR.
It is possible that some terminals or computers use the DTR and DSR pins for
hardware handshaking instead of the RTS and CTS pins. When this is the case,
you must connect the DTR terminal output to RTS on the KAM’98, and connect
the DSR terminal input to CTS on the KAM’98.
Software settings
When using a standard terminal program to communicate with the KAM’98, you
must set the serial port configuration in your program for 8 data bits, no parity,
and one stop bit. The baud rates supported by the KAM’98 are 300, 600, 1200,
2400, 4800, 9600, 19200 and 38400. In general you should use the fastest baud
rate your terminal program and hardware supports. The KAM’98 defaults with
ECHO ON, so you should set your terminal program for “full-duplex” operation.
If you are using a baud rate above 9600 baud, we strongly recommend that you
consider installing special high-speed, buffered UARTS in the serial port of your
computer. These UARTS are available through many parts suppliers and will im
-
prove the reliability of high-speed communications. You should ask for the
“high-speed buffered UARTS” (part number 16550 or equivalent) when ordering
from your supplier. Most Pentium systems have these already.
