DIP Switch Settings
DMP1
| DMP1 DIP Switches | ||||
| Function | Off = High = 1 | On = Low = 0 | Software | |
| DS1-1 | International characters Bit0 |
7=off:off:off=USA (default) |
Cannot be changed by software | |
| DS1-2 | International characters Bit1 | |||
| DS1-3 | International characters Bit2 | |||
| DS1-4 | CR Function | CR only (default) | CR & LF | Affects chr(0Dh) |
NLQ401
| NLQ401 DIP Switches | ||||
| Function | Off = High = 1 | On = Low = 0 | Software | |
| DS1-1..8 | Reserved | DS1 is not installed, DS1-1..7 floating (without pull-up), DS1-8 hardwired to GND (On) | ||
| DS2-1 | Page length | 11 inch (default) | 12 inch | Can be also changed via ESC "C" |
| DS2-2 | Line Feed Spacing | Force ESC "2" to act as 1/8 or 1/6 inch Note: Service manual claims DS2-2 selects UK/French characters, that is wrong, not supported by firmware |
Can be also changed via ESC "A" | |
| DS2-3 | International characters | Select US-ASCII or German characters | Can be changed by ESC "6" / ESC "7" (which are NLQ401-specific codes, non-Epson compatible) | |
| DS2-4 | Draft/NLQ Mode | Select Draft or NLQ mode Note: Service manual claims it selects Slashed/Unslashed Zero, that is wrong. |
Can be also changed by ESC "x" (Epson-compatible code), or by ESC "I" (equivalent NLQ401-specific, non-Epson compatible code) | |
| DS2-5 | 1 inch skip perforation | Invalid/Disable (default) | Valid/Enable | Can be also changed via ESC "N"/ESC "O" |
| DS2-6 | Not used | Unused according to service manual, that is wrong. It seems to control something like wrapping to next line when the line is full (or so) | ? | |
| DS2-7 | CR Function | CR+LF | CR only (default) | Affects chr(0Dh) / Also affected by /AUTOLF signal |
| DS2-8 | SLCT IN Exchange | External | Internally fixed (default) | ? |
