Xantech Connections, MRKP2 to MX88 and Expansion Keypads, Internal IR Receiver

3. Connections

MRKP2 to MX88 and Expansion Keypads

Each RJ-45 connector under each PREAMP OUT (1 – 8) is considered a “Zone port”. This Zone port interfaces with MRKP2 Keypad through CAT-5 cables. These connectors carry command/control information between the keypad and the MX88. Connect CAT-5 cables terminated to an RJ-45 connector from each Keypad to the corresponding RJ45 connector of the MX88 as shown below. (See Specifications section for maximum length of Cat-5 cables)

KEYPADS

Note:

1.There are four keypads maximum per zone. Remove termination jumper on all keypads except for the last keypad (see location of JP1 on Fig 2.4). Each expansion keypad must each have its own unique address. (see Installer Settings menu on Section 4 of this manual).

2.Long CAT5 cable runs and/or the use of more than one keypad per zone will require the use of MRC44CB1 and 782ERGPS High Current AC adaptors. Please see Important Notes on page 6 and the Specifications page for more details.

Internal IR Receiver

The internal IR receiver is located beneath the keypad’s face plate between the POWER and “X” buttons (see Figure 2.3). The internal IR receiver receives IR commands for the MRKP2 and for the MX88. It will also pass-thru IR remote control commands to audio sources, via an emitter, to each of the sources connected to the MX88. The internal IR receiver is interference friendly. However, some optically noisy environments may require the use of an external IR receiver. (See Figure 3.1 for details on using an external IR receiver)

Compatible Handheld remotes

The MRKP2’s can be controlled with a Xantech handheld remote controller, such as a Xantech RC68 or MREM is for accessing control functions of the source such as navigation, menu, and transport controls. Other programmable Xantech remotes such as XTR39 can also be used. The list of RC68 codes is available at www.xantech.com/Controls/KeypadsRemotes/Remotes/MREM, in the Products page, under “MREM Code List”.

Note: RC68 commands may not be used with projects created in QuickConfig.
