Expert Sleepers - FHX-1 Output Expander for FH-1 User Manual

4/4
FHX-1s are connected in the same manner. All the expansion cables are oriented the same way - if you nd
yourself twisting the cables, chances are you're inserting the ends incorrectly. With a row of FH-1/FHX-1s,
all the cables should stay at.
Note that each FHX-1 requires its own individual power connector as well as the expansion connector.

There are 11 possible jumper positions on the FHX-1's PCB.

The 8 jumpers numbered JP1-8, situated in a row above the jack sockets, set the voltage range for each
output. The options are:
±5V - jumper in lower position (factory default setting)
0-10V - jumper in upper position
0-5V - jumper not tted

Next to the Expansion IN connector are two 3-way jumper blocks numbered JP9 & JP10. These are used to
select which of the possible 8 expansion channels this FHX-1 responds to.
Channel 'zero' is the FH-1 or FH-2 itself. Channels 1-7 are the expansions channels, corresponding to
outputs 9-64.
The expansion channel is selected by placing jumper links in a binary pattern between JP9 and JP10. As
shipped (and as in the photo above), a jumper is placed in position '3', which corresponds to a value of 1,
so the FHX-1 responds on expansion channel 1.
The position labelled '2' corresponds to a value of 2, and the position labelled '1' corresponds to a value of
4. Therefore, the 7 expansion channels are selected by placing jumpers as in the table below:
