                Y cable for FP40 laser printer option
                            09/27/94 - med

If you wish to use the laser printer option and the RS232 option 
on the FP40 at the same time, you will need to build a Y-cable
adapter as shown below. The Y-cable replaces the printer cable, 
but not the RS232 cable. The FP40 plug of the RS232 cable is 
attached to the "Computer" connector. The following diagram shows 
how to build the required Y-cable.
