The Short Line (SL) kits consist of the cable assembly only.  The Long Line (LL)
 kit consists of the DP-LL board only, and requires the proper connector provided
 by the appropriate DP-SL kit.

Unlike the 4400 product lines, the 4800 series implementation of the Dataproducts 
interface kit allows for the serial interface connector to remain, and hot-port 
switching is retained.

* Setting Straps.
Jumpers must be set on the older model printers with the SMPI board- refer to the 
User's manual or the Service manual.  Newer models will automatically set the Hardware 
Straps to default when DataProducts emulation is selected.

* Prints Garbage After Installation
If high order ASCII characters are printed after installing a DP interface, the data 
line is probably missing Data Bit 8.  Pull-up resistor on the interface board will 
set bit 8 high.  This is typical of many older To set bit 8 to zero, set Parallel 
Interface Strap A8 to OUT.

* QMS Magnum board
When installing the QMS Magnum board with a DP-LL interface. the QMS board requires 
the installation of a fuse to power the DP interface board.  
Use a 250V, 1A, 5 x 20mm fuse.
