1. The printer is equipped with standard parallel output interface and 25-core RS232 connector
assembly. See definition of its pins in Figure 2-4.
2. Printing directions:
▲! The printer may be used only after completing relevant settings. All relevant
paremeters of the printer must be set before using it.
▲! Connection between printing interface output pin of the indicator and the printer must
be accurate without fault. Only dedicated connecting wire for printing may be used.
(Indicator must be connected with printer by appropriative cable accurately.) If wrong
connection occurs, output interface of the indicator or that of the printer and even the
indicator and printer may be damaged.
▲! When using printer, connect all lines accurately at first, then switch on the power of
indicator and at last the power of printer. After use, please turn off the printer first
