Connector Configuration
1200 baud radio port (DB-9)
The DB-9 connector (1200 baud radio port) may be configured to allow you to perform a hard re-
set on your KPC-9612 without opening the case. To do this, place jumper J21 on the center post
and the post marked 2. This connects pin 9 of the DB-9 connector to the KPC-9612 reset circuit. In
this configuration, you may hard reset the KPC-9612 by placing a ground on pin 9 of the DB-9 con-
nector and applying power to the KPC-9612.
You may also configure the KPC-9612 to receive dc power from the 1200 baud radio port. To do
this, place jumper J16 on the center post and-2, and J17 on the center post and 2. Your KPC-9612
may now be powered for operation by applying 12 VDC to pin 7 of the DB-9 connector.
WARNING: If you set jumpers J16 and JI7 to provide power through the serial port or through the
1200 baud radio port, you must be very careful that this voltage is not applied to the RESET pin
(jumper J17 pin 1). Failure to observe this warning will result in damage to the DS1232 reset chip.
Serial port (DB-25)
The DB-25 serial port of the KPC-9612 is configured for a standard RS-232 interface as shipped
from the factory. There are several options available by using the internal junipers as described be-
low:
Applying power to the KPC-9612
By placing jumper J16 on the center post and 1, and juniper J17 on the center post and 2, you
may power the KPC-9612 by applying 12 volts dc to pin 25 of the DB-25 serial connector.
WARNING: If you set jumpers J16 and J17 to provide power through the serial port or through the
1200 baud radio port, you must be very careful that this voltage is not applied to the RESET pin
(jumper J17 pin 1). Failure to observe this warning will result in damage to the DS1232 reset chip.
DTR/DSR/RTS/CTS connections
Normally the KPC-9612 has the DTR pin (pin 20) connected to the DSR pin (pin 6) on the serial
port. This is a loopbaek of the DTR signal from your computer to provide the DSR signal. Many
computer require this for proper serial port operation. If your computer requires DSR but does not
supply DTR, you should install a 10 kOhm, 1/4 Watt resistor at R1.
If you need to isolate the DTR/DSR connection, cut the metalized trace between the two pads of
J19. It is also possible to connect the RTS input to the KPC-9612 to the DTR signal from your com-
puter by placing jumper J20 on both posts.
The CTS line from the KPC-9612 may also be connected to the DSR line by placing jumper J18 on
both posts.
Example
One possible use for these jumpers would be to allow the use of a low-speed Macintosh modem
cable with the Host Master Mac software and your KPC-9612. The low speed modem cable uses
the DTR line and the CTS line for hardware handshaking, and the KPC-9612 uses the RTS and CTS
line. In this case, placing jumper J20 on both posts would connect the DTR and RTS lines together
so the cable would work properly.
