Several of the circuit boards in the printer have jumpers and/or DIP switches used to control the functionality of the board. These settings are described the following section.
Signal Interface Board SettingsThe signal interface board has both jumpers and DIP switches used to control host interface interactions.
In general, the four jumpers on the signal interface board should remain as set at the fac- tory. The jumpers control the following:
Table
Jumper | Direction | Description |
|
|
|
JP1 | Baud rate crystal oscillator on IGS board 3.6854 MHz | |
| Baud rate crystal oscillator on IGS board 7.3728 MHz | |
|
|
|
JP2 | Unsolicited status reports enabled after | |
| Unsolicited status reports disabled after | |
|
|
|
JP3 | ERR (pin 32) error line output enabled | |
| No jumper | ERR (pin 32) error line output disabled |
|
|
|
JP4 | PE (pin 12) out of paper line enabled | |
| PE (pin 12) out of paper line disabled | |

The four DIP switches on the signal interface board should be changed based on the host interface being used.
