2.8 Installing an Optional PS-2 Keyboard
To increase the speed and ease of entering alpha-numeric data, a standard PS/2 keyboard can be connected. Use
the following steps to install a PS/2 keyboard.
1. Place the 920i into Setup Mode by pressing the setup switch. See Section 1.1 (setup mode) for finding
and pressing the setup switch. This may involve breaking an inspectors lead seal.
2. When the 920i enters into Setup Mode, Scales is selected. Press the right arrow key on the keypad, so
Serial is selected.
3. Press the down arrow key once. Port 1 is selected.
4. Press the right arrow key once to select Port 2.
5. Press the down arrow key one. CMD will be selected.
6. Press the right arrow key once to select KEYBRD.
7. Press the Up arrow key twice. SERIAL should be selected and there should be a Save and Exit softkey in
the lower right-hand side of the display.
8. Press the Save and Exit softkey.
9. Power down the CB-2 with the key switch.
10. Bring the end of the PS/2 keyboard cable into the CB-2 through one of the cord grips on the back of the
enclosure. Plug in the PS/2 keyboard into the PS/2 connector (located between the display contrast
potentiometer and the DB-9 serial port) about 2” away from the setup switch. Your CB-2 may be
equipped with an optional keyboard connector extension. If this is the case, there will be a cable running
out of the back of the CB-2 enclosure with a female PS/2 connector on the end of it.
11. Power up the CB-2 with the key switch.
12. Test the keyboard. F1 to F5 on the keyboard should map to the softkeys from left to right, respectively.
