onds. The programmer reads and writes to virtual registers as
variables, and does not contend with the hardware details.
Initial PK 2100 Setup
When the
PK2100
powers up, it consults its board jumpers, the
keypad if any, and the contents of the
EEPROM
to determine its
mode of operation. The modes of operation are the following:
• Run a program stored in battery-backed
RAM
.
• Prepare for Dynamic C programming at
19
.
2K
baud using
the
RS232
port (“phone” jack).
• Prepare for Dynamic C programming at
38
.
4K
baud using
the
RS232
port.
If your controller has a keypad, you can use it to select the op-
eration mode. Hold down the menu/setup key and one other
key simultaneously (field/run, up/pgm
19
.
2
, or down/pgm
38
.
4
).
The unit will beep to acknowledge the change of operating
mode. In unusual instances, you might also need to cycle
power while holding the key combination.
If the keypad is not available, or you want to override the key-
pad, use the jumper block
J4
.
Connecting the PK 2100 to your PC & Dynamic C
1 Connect the red-tagged lead from your
24V
(or
12V
) power-
supply to the +
24V
screw connector. Connect the other
power supply lead to the
GND
screw connector.
2 Plug the serial programming cable into the
PK2100
jack and
connect it to a
PC
serial port.
3 Plug the
PK2100
’s power supply into a wall socket. Start Dy-
namic C.
