Section 7: Appendix

INTERFACING SPLCD with MRC44 (IR Control) & MRC88 (MRC88 Emulation)
The SmartPad LCD™ allows direct integration with Xantech MRC Products via the CONTROL and
EXPANSION RJ45 Terminals on the SPLCD Rear Panel (Figure 3 – Items 13 & 14). Connecting either of
these terminals to a Zone Keypad Connection on the rear of a MRC44 or MRC88 allows IR control of the MRC
and any components connected to the MRC Controller.
NOTE: An external 16VDC Power Supply must be connected to the +16V In Only and GND Terminals on the
IR Bus Connections on the SPLCD Rear Panel. (Figure 3- Items 19a & 19b) A MRC cannot power a
SPLCD.
MRC88 EMULATION MODE: FEATURE DESCRIPTION & PROGRAMMING

SPLCD/MRC88 EMULATION MODE

The full line of SmartPad™ LCD Controllers can be seamlessly integrated into a new or existing MRC88 or
MRAUDIO8X8 System over the existing CAT5 cable. This allows the SPLCD to initiate any macro programmed
in the MRC88 Controller without the use of IR commands. All Macro Programming resides in the MRC88
allowing for ease of initial programming and any upgrades that should be required. For simplicity, MRC88 and
MRAUDIO8X8 will be referred to as MRC88.

Connecting the SPLCD to the MRC88 Controller

1. Connect one end of the CAT5 to the appropriate Zone Keypad Terminal on the MRC88 Rear Panel and
the other end to the Controller Terminal on the SPLCD Rear Panel.
2. Connect a 16V DC Power (Xantech Part # SPLCDPS1) directly to the IR Bus +16V DC and GND
Terminals on the SPLCD Rear Panel.
NOTE: The SPLCD cannot be powered directly from the MRC88 Controller.
3. If using multiple keypads in a single zone, the last keypad in line must have the Zone Termination Jumper
installed.
NOTE: SPLCD comes with the Zone Termination Jumper installed by default.

Configuring Dragon Drop SPLCD for MRC88 Emulation Mode

1. Program the MRC88 as you would for a standard MRC88 Keypad using both Tier 1 and Tier 2 on the
buttons for added functionality if desired.
2. Create the graphic layout for an SPLCD Project in Universal Dragon as appropriate for the system being
controlled. Place Source and Function GTL's as required.
3. After all of the GTL's are laid out, as is done in a standard SPLCD project, click the Project Options Icon
in the Tool Bar. The Options Window will appear. (Figure 53)
4. Click the MRC88 Emulation Tab. Select (check mark) the box: Emulate MRC88 Keypad.
5. If you are using multiple keypads in a single zone, set each keypad to a unique Keypad Address. Up to
four keypads can be used in a single zone.
NOTE: If using standard MRC88 Keypads in conjunction with the SPLCD in a zone, you must also set the
MRC88KP Address Jumper to a unique address.
6. Under MRC88 Source Names enter the names as they appear in the Universal Dragon MRC88 Project.
NOTE: This is necessary for proper Source Name display when using the MRC88 Status function.
