3] JUMPER SETTINGS
As shown in Figure 3, there are 5 jumpers on the
CA-A460-P which set some of the module's opera-
ting modes.

EOL JUMPER
Place the EOL jumper ON when the CA-A460-P is at
the beginning (Start Point) or at the end (End Point)
of the E-Bus network. Otherwise, place the jumper
OFF. See Figure 4.

this jumper sets the addresses of the modules.
Set the fi rst module's ADR jumper to ON to set
the module's address to Expander 1. A module
with an address of Expander 1 recognizes the
on-board relays as relays 3-9 when connected to the
CT-V900-A controller. Set the second module's
jumper to OFF to set the module's address to
Expander 2. A module with an address of Expander 2
recognizes
the
10-16 when connected to the CT-V900-A controller.
