Function
Functions the same as the shift key on a typewriter. When in SET-UP mode,
SHIFT can also be used with other keys to select LA 120 features.
Causes alphabetic keys to transmit shift (uppercase characters) codes, regardless of
the position of the SHIFT key. CAPS LOCK does not affect numeric or other
keys.
Causes LA120 to transmit a short break signal (233 ms). When used with SHIFT,
causes LA120 to transmit a long break disconnect signal (3.5 seconds).
Allows operator to view last character printed.
1.2.6 Optional Numeric Keypad
The numeric keypad allows numbers to be entered in adding machine fashion. Each number key,
minus key, and comma key, normally generate the same codes as the corresponding unshifted keys on
the main keyboard. The SHIFT key does not affect the numeric keypad.
In the alternate keypad mode, the keys generate escape sequences that may have special meanings
(Chapter 3). The PF1, PF2, PF3, and PF4 keys generate escape sequences that may have special
meanings (Chapter 3). The ENTER key normally corresponds to the RETURN key. In alternate
keypad mode, ENTER generates an escape sequence that may have a special meaning (Chapter 3).
1.2.7 Power ON/OFF Switch and Voltage Selector Switch
The power switch controls power application to the LA 120. The switch is located on the LA 120 lower
front panel (Figure 1-3a). Terminals currently being manufactured also contain a voltage selector
switch. The voltage selector switch is located above the power ON /OFF switch. Place the tip of a pen
into the selector switch indentation and select the appropriate voltage, as shown in Figure 1-3b.
CAUTION
Failure to set the switch to 230 V when plugging the
LA120 into a 180-256 V power source will damage
the power supply.
