Technical Tips for Ohtsuki Embossers

General Advice about Computer Ports: Serial, Parallel, USB, and Network

The emb.elt table asks for "PageWrap". This means when the embosser is finished with the last possible line on the page, the software sends a carriage return (end of line indicator) without a form feed command (end of page). If there were no PageWrap statement in the emb.elt, then the user would have to use one less line per page. However, that "extra" line does come at a price: the emb.elt table must give the precise number of lines per page that the embosser is capable of embossing (for that form size) or else the page format gets messed up. If you have output problems make sure you know how many lines the embosser can produce for that form size. Then make sure that number is in the emb.elt table (the second number after the singlepage/doublepage command for the form you are using.

Parallel Setup Guidelines

The Ohtsuki factory defaults should work well with this software. The only issue is that you need a special parallel cable. In a standard parallel cable, wire 17 from the PC connects to wire 36 on the printer, and wire 11 on the PC connects to wire 11 on the printer. For the modified cable, disconnect both of these connections and then connect wire 11 on the PC to wire 36 on the printer (Wire 17 on the PC should not be connected to anything, and wire 11 on the printer should not be connected to anything).

If you run into problems and you have narrowed the cause down to the hardware, you may wish to double check the DIP switches. Turn off the printer and remove the DIP switch cover plate as instructed in the Ohtsuki manual. Switch banks two and three have no purpose unless you are using serial communications. Switch bank one should be configured as follows (ON=up. OFF=down):

After putting the cover back on the switch banks you can plug in the Ohtsuki, attach a parallel printer cable from your computer, and power on the unit. If you encounter problems driving the embosser, please see the operating tips.

Serial setup guidelines

The Ohtsuki internal serial communication protocols are different from most embossers and have changed from time to time, but by telling this software that you are using an Ohtsuki, and by giving special attention to the serial setup guidelines, it can be used successfully.

First, you need to arrange your DIP switches for serial communications. These settings are only a recommendation based on the fact that most computer systems configure the serial ports for 9600:n:8:1 (for the: baud rate, parity, data bits, and stop bits, respectively). If for any reason you require a setting other than 9600:n:8:1, you need to adjust the Ohtsuki DIP switches accordingly. Make sure that the unit is powered off, remove the plate covering the DIP switch banks as instructed in the Ohtsuki manual. Next, adjust the switches as follows (ON=up. OFF=down):

After putting the cover back on the switch banks you can attach the power cord and plug in the unit. You need a serial cable to attach the Ohtsuki to your serial (COM1 or COM2) port. The exact type of cable required will depend on your computer's serial connection.

Control Panel & Operation

The front panel of the Ohtsuki consists of three lights and three buttons. The three lights indicate power on, on-line status, and paper empty. The three buttons are used to toggle between on-line and off-line status, to do a single linefeed, and to do a form feed. Because the Ohtsuki is on-line when it is first powered up, and because the index holes keep track of page endings, normally you should not have to push any buttons to get the Ohtsuki to emboss from this software.

When the Ohtsuki is set for print and braille, it spaces out the lines so that only 19 lines fit on a page. To fit the standard 25 lines on a page, add the sequence Escape lT (Escape, lower case letter l ("el"), uppercase T) as a set up sequence. If you only want braille from the Ohtsuki, send the control sequence Escape B (Escape uppercase B).
