2.2.2 START-UP LANGUAGE/COMPATIBILITY MODE/GPIB ADDRESSING DEFAULT (SEE FIG-
URE 2-1)
Program Mode Bits P1 (DIP switch position adjacent to Address Selector Switch A5, see Figure
2-1) and P2 (right-most position) control the start-up command language, secondary GPIB
addressing with SCPI, and Compatibility Mode as defined in Table 2-2.
Language - Selection is provided to choose either SCPI or CIIL command language. If SCPI is
selected, you can also choose to implement either primary or secondary GPIB addressing. CIIL
is select by changing P1 to 1 and P2 to 0. SCPI selection with secondary addressing is selected
by changing P1 to 0 and P2 to 1.
Compatibility Mode - Certain features of the TMA 4882-27 can be configured to be fully 488.2/
SCPI compatible (Mode 0) or to be backward compatible with previous Kepco products (Mode
1). Differences between Mode 0 and Mode 1 functionality are explained in Table 2-3.

(backward compatible with previous Kepco products)
Device Clear
Clears internal registers but leaves
output voltage and current unchanged. Clears internal registers, sets output voltage and current
to zero, sets output to OFF, and, if unit incorporates
relays, opens relays.
Status Uses Status Instrument Registers. Does not use Status Instrument Registers.
PON enable All status register enables are set to 0. All status register enables are set to 32767.
