Interface

Specifications:

• Data Transmission Method: Asynchronous Serial.
• Handshaking: DTR/DSR Control
• Default Protocol: 9600/19200 bps, non-parity, 8 data bits, 1 stop bit.

Communication Protocol

Receive Data.
The DTR signal is as follows:

• [HIGH] This indicates that the display isn’t ready to receive data. It depend on the following conditions:
  • The period from when the power is turned on to when the printer first becomes ready to receive data.
  • When the remaining space in the receiving buffer becomes 128 bytes or less.
  • When the DTR signal of the printer is HIGH when the printer is selected using the command.
• [LOW] This indicates that the display is ready to receive data. It depends on the following conditions:
  • When the printer first becomes ready to receive data after power-on. ‰When the remaining space in the receiving buffer becomes 128
    bytes or more. When the DTR signal of the printer is LOW when the printer is selected using the command.

Transmit Data
After confirming the DSR is LOW, data is transmitted to the printer.

Interface Conversion Adapter
The interface adapter section has connectors for the display panel, the printer, the power supply, and host computer. All the data transmitted from the host computer will be received by the display. If this data is for the display, the data will be processed, and if it is for the printer, it will be transmitted to the printer. Whether the data is for the display or the printer can be switched using the peripheral device selection command.

• US . n (Decimal Point) / US , n (Comma) / US ; n (Semicolon):
  The displayed character codes are form 32(20h) to 127(7Eh), and 128(80h) to 255(FFh) in the character code table. The period/comma/semicolon displayed only for n. The period is not displayed for the subsequent display characters.
• US # n m (annunciator):
  [ range ] n = 0(00h) or 1(01h) / m = 0(00h)~20(14h)
  [ notes ] When n= 0, the annunciator at column m is turned off.
  When n= 1, the annunciator at column m is turned on. ”m” specify column number (the most left column is column 1) at which annunciator to be turned on/off is placed.
  When m = 0, all annunciators are turned on or off. Once an annuciator(s) is turned on, it remains on until turned off by this command, the ESC@ or US@ command is executed, or the power is turned OFF.
  [example]:
  • To turn on the annunciator at the third column:[n = 01h ], [ m = 03h ]
  • To turn off all the annunciators: [n = 00h ], [ m = 00h ]

Above commands relating decimal point, comma, semicolon, and annunciator may not be available due to hardware limit of display tube.
