Relations among the ON LINE switch, SLCT IN signal, DC l/DC 3 code and
interface signals are shown in Table 9 below.
Table 9
DC 1/DC 3 and Data Entry
NOTES: 1. In Table 9, it is assumed that as soon as the Printer receives data. it
sends back the ACKNLG signal, though this data is not stored in the
print buffer. In this status, the Printer is waiting for the DC 1 code for
normal entry.
2. The DC l/DC 3 code is valid under the condition that the DIP switch
pin l-8 is OFF, namely, the level of SLCT IN at the pin No. 36 of the
interface connector is “HIGH.” When SLCT IN is “LOW,” the DC l/DC
3 code is not valid.
(14) NUL (Null)
The NUL code is regarded as the termination for tabulation setting
sequence (described in detail later).
(15) BEL(Bell)
When the BEL code is input, the buzzer sounds for about 3 seconds.
(16) Escape (ESC) control
(a) Escape numerical control
Input of an “ESC” code followed by an ASCII numeric code permits
each of the following functions to be performed.
1) ESC 0(Escape 0)
Receipt of an “ESC” followed by ASCII code “0” causes the line
spacing to be set at 1/8 inch. Input of the ESC 2 code
ormsignal
to the interface connector or turning the power off and on again
causes the line spacing to return to 1/6 inch.
