8.Coding Tables

(1)Table 6 shows all available codes when the Printer is set for operation with standard coding by setting the DIP switch pin 2-4 to the OFF position. This DIP switch pin is factory-set to the OFF position.

(2)When the DIP switch pin 2-4 is turned ON, the Printer behaves as a com- pletely compatible printer to the Tandy Personal Computer TRS-80. The available codes in this case are shown in Table 7.

Note that all the other pins of DIP switches 1 and 2 will not function irrespective of their ON/OFF positions whenever the DIP switch 2-4 is turned ON for TRS-80 mode.

(3)Table 8 shows Special Characters/Symbols which are selectable by the DIP switch pins 2-1 and 2-2 as described in paragraph 6 above.
