Specifications

PK2100 Series Z-World 530-757-3737 10
onds. The programmer reads and writes to virtual registers as
variables, and does not contend with the hardware details.
Initial PK2100 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 PK2100 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.
