Cable Wiring
All Kantronics software requires five wires between the computer and the
KAM’98. The pins that must be connected from your KAM’98 to the computer
for these programs are Txd, Rxd, SG, RTS, and CTS. If you are using other soft-
ware, you should refer to that documentation to determine the cable requirements
for proper operation. Some software does not support hardware flow control and
may fail to operate if the RTS and CTS lines are connected.
The KAM’98 serial port connector has 25 pins, which are configured at the fac-
tory as:
Pin KAM’98 Computer Pin Number
Name
Pin Number (DB-9) (DB-25)
FG 1 N/A 1
TXD 2 3 2
RXD 3 2 3
RTS 4 7 4
CTS 5 8 5
DSR 6 6 6
SG757
DCD 8 1 8
DTR 20 4 20
NOTE: FG (Frame Ground) and SG (Signal Ground) are tied together in the
KAM’98.
