Address Switch Settings
The address select switch must be set to the correct address for the system to function. The
default setting for a single IO Blox is for both switches 1 and 2 set to Off. When you add
multiple IO Blox devices, each additional device must be set to the correct address. See
Installing Multiple IO Blox Devices
When installing more than one IO Blox device in a system, you must connect the devices
with the supplied cables, and set the address select switch correctly for each additional
device.
1. Locate the IO Blox-to-IO Blox cable that was supplied with the system. See
for the details of the cable options.
2. Plug one end of the cable into the JCBL2 connector on the first IO Blox.
3. Plug the other end of the cable into the JCBL1 connector on the second IO Blox.
4. Continue this cabling process for any additional devices.
5. Set the address select switch for additional devices. See
NOTE:
Each IO Blox device (up to 4) must have a unique address. IO Blox
devices with duplicate addresses will conflict.
See also the note on
for the maximum cumulative cable length between IO Blox
devices.
