DIP SWITCH USAGE GUIDE

Gefen CAT5 Extreme products (sender and receiver) both contain a pair of dip
switches located underneath the unit. These dip switches are used to select from
sets of configurations that will equalize the signal to best match the conditions in your
setup.
Receiver Configuration Sender Configuration 10m to 33m Cables
Dip #1 Dip #2 Dip #1 Dip #2
Off Off Off Off Very Good quality cable
On Off Off Off Good quality cable
Off On Off Off Medium cable
On On Off Off Bad cable
Dip #1 Dip #2 Dip #1 Dip #2 2m to 10m Cables
On Off On Off Very Good quality cable
On / Off Off On Off Good quality cable
Off On / Off Off Off Medium cable
On On / Off Off Off Bad cable
Adjustment Guidelines:
1) Dip #1 and Dip #2 on the receiver are Equalization Controllers
a) When both are OFF Equalization is zero => Good quality cables or Bad
quality short cables.
b) When both are ON Equalization is max => Bad quality long cables.
2) Dip #1 on the sender side should be ON when a short and good quality cable is
connected
