PK2100
2-2 s Getting Started
Initial PK2100 Setup
When the PK2100 powers up, it reads its board jumpers, the keypad, if
any, and the contents of the EEPROM to determine its mode of operation.
The following modes of operation are available:
1. Run a program stored in battery-backed RAM.
2. Program at 19.2 kbaud using the RS-232 port.
3. Program at 38.4 kbaud using the RS-232 port.
The keypad (Figure 2-1) may be used to set the mode. Hold down the
MENU/setup key and one other key (FIELD/run, UP/pgm 19.2, or
DOWN/pgm 38.4) simultaneously. The unit will beep to acknowledge the
change of operating mode.
A jumper installed on jumper block J4 overrides any keypad settings. The
jumper block must be used when a keypad is not available, for example,
in the PK2120 controller. Figure 2-2 illustrates the jumper configurations.
