ADDING XCARDs TO THE EXP9
Normally you would purchase the EXP9 from Xantech with the correct number of zone cards pre-loaded
at the factory to match the requirements of the installation. To install additional XCARD(s), however, when
a client later requests more zones, proceed as follows:
1. If the EXP9 is connected to a ZPR68-10 with the ribbon cables, unplug them at the EXP9 end.
2. Be sure the EXP9 is
not powered (unplug the power supply from the EXP9).
3. Remove the top cover by removing the five screws on each end of the EXP9 and the screw just under
the Video jacks on each of the existing Zone Outputs. Carefully lift the cover off.
4. Remove the screws that secure the cover plates of the unused zone slots where you desire to install
the zone XCARD(s). Discard the unused plates.
CAUTION: The zone XCARD(s) can be damaged by electrostatic discharge. It is recommended that
you use a grounded antistatic wrist band when you are handling and inserting the XCARD(s).
WARNING: Damage caused by electrostatic discharge is not covered under the Xantech warranty!
5. Remove the new XCARD(s) from their packaging and carefully insert them into the desired slots on
the main PCB.
Be sure to accurately align the pins on the XCARD(s) to the pin holes on the slot connector. Refer to
a previously installed card for orientation and placement.
Exert an even downward pressure until the card(s) are fully seated.
6. Reassemble the top cover onto the unit.
Be sure to carefully align the holes in the top cover with the jacks and the LEDs on all the PCB's before
pressing it down into place and replacing the screws.
INSTALLATION
To install the ZPR68-10/EXP9 combination into the application, use the same INSTALLATION procedures
as given in the ZPR68-10 INSTALLATION INSTRUCTIONS manual. You can treat the installation exactly
the same, the only difference is that you are now dealing with more zones. The following additional items,
however, may apply to your installation:
Adding an EXP9 to an Existing ZPR68-10 Installation.
In this case, it will be necessary to redo the Input Level TRIM adjustments. Proceed as follows:
1. Connect a Xantech IR receiver to one of the zones
on the EXP9.
2. Be sure all system components are connected and operating and that the provided power supplies
are plugged into the ZPR68-10 and the EXP9 and the red POWER LED's are ON.
3. Aim the RC68 at the IR receiver and perform the TRIM adjustments as given in the ZPR68-10
instructions under "SETUP PROCEDURES" and "Adjusting Input Level TRIM".
The redone adjustments affect all zones, including those on the ZPR68-10.
Unplugging the Power Supply to the EXP9
The custom trim and zone adjustments you perform on the EXP9 will default to factory settings if the EXP9
power supply is unplugged before the power supply of the ZPR68-10 is unplugged. To avoid this, when
powering the system down, proceed as follows:
1. Unplug the ZPR68-10 power supply
before unplugging the EXP9 power supply.
2. When powering up, plug the ZPR68-10 in first, then the EXP9.
When the units are powered down and up simultaneously, as when a power failure occurs, loss of trim or
zone adjustmentsettings
will not occur.
