AutoPatch Preset Single Bus Controllers

Overview

Preset Single Bus Controllers (SBCs) are control devices programmed as channel­selector devices for a specific preset. Preset SBCs can be configured to execute
global presets or to execute local presets on a particular virtual matrix. (Preset SBCs
cannot be programmed to act as a standard channel selector device to a specific
output, nor can standard SBCs act as Preset SBCs.) Preset SBCs are available in
2-digit and 3-digit 12-key models and are compatible with any AMX AutoPatch

Distribution Matrix with an XNNet compatible interface.

Installation

ESD Warning: Avoid ESD (Electrostatic Discharge) damage to sensitive
components; be sure you and the equipment are properly grounded before
touching any internal materials.

This guide provides instructions for a typical installation using a single-gang box. For
other installations, see Steps 9 through 11 in right column before mounting the Preset
SBC.

Important: If installing multiple Preset SBCs, see the section on linking (on reverse)
before mounting Preset SBCs in boxes.

Mounting & Wiring the Preset SBC

Power Requirements

• +9 VDC @ 120 mA per Preset SBC

• Always use a UL approved power source. Check the power source’s
documentation for information specific to that power source.

Link Cable Requirements

• Two-conductor, 20 AWG, 7/28 strand cable with a drain wire or shield, such as
Alpha 2412C (customer supplied)

• Maximum length of cable: 1,000 ft. (304.8 m) total, including linked SBCs

To mount in a single-gang box:

1. Install a single gang box in the desired location.

2. Attach link cable to enclosure’s XNNet connector (on the enclosure’s CPU). For
exact location of CPU and instructions for attaching a link cable, see router
documentation.

3. Route the link cable from the enclosure throug h the hol es in th e sin gle gang bo x.

4. Attach power cable wires to the power source.

5. Route power cable from power source through holes in the single gang box.

6. Snap the bezel on the Pr e s e t SBC.

7. Carefully pierce the two gray circles near the top and bottom of the Preset SBC
faceplate that indicate the mounting holes (if necessary).

8. Align faceplate with the single-gang box. (The unit may need to be tilted slightly
to move the circuit board past the tabs.)

9. Wire the Preset SBC power connector P3.
For the 2-digit SBC, use Steps 9a and 9b.
For the 3-digit SBC, use Steps 9c through 9e.

Wiring the Power Connector (P3)

2-digit Preset SBC

9a. Loosen the left and center screws of

the power connector P3 on the circuit
board on the back of the SBC
(see right).

9b. Insert power cables wires; positive

lead on the left and ground in center.
Tighten screws.

of the ground wire to a ground point.

9d. Loosen the top and center screws of

the power connector P3 on the circuit
board on the back of the SBC
(see right).

9e. Insert power cable wires; positive lead

on top and ground in the center.

Linking Multiple Preset SBCs

Note: Each enclosure supports 32 Preset SBCs (or a total of 32 XNNet compatible
devices, such as remote control panels and status displays).

Preset SBCs can be linked together in a daisy chain to create multiple control points
for a single system. XNNet link cables can be attached to either Comm Link. The
total distance of the cable runs cannot exceed 1,000 ft. (304.8 m).

To link Preset SBCs:

3-digit SBCs linked

FIG. 4

1. Connect the first Preset SBC to the router using one of the Comm Links
(P4 or P5; see Steps 9 through 11 previous page).

2. Attach an XNNet link cable to the Preset SBC’ s other Comm Li nk, following the
same procedure used when connecting to the router.

3. Attach the other end of the XNNet cable t o a Comm Link on t he second P reset
SBC.

4. Repeat Steps 2 and 3 for any additional Preset SBCs.

5. If required* terminate the final SBC. Loosen the two outer screws, insert a 120
ohm resistor (customer supplied) in the outer contacts, and tighten the screws
(FIG 4).

*On large control networks, termination may be required on the last linked
Preset SBC.

Termination may be
required (see Step 5)

Operation

Apply power to the Preset SBC and the system (see router's documentation for
powering up procedure).

Programming & Entering Presets

Note: Preset SBCs cannot be programmed to act as a standard channel selector
device to a specific output.

To program presets:

Local presets must be pre-programmed in XNConnect and executed on a single
virtual matrix. For instructions on programming local presets see the XNConnect
Help file.

Global presets can either be defined using BCS commands or from a control p anel (if
supported by the panel) and affect routing on all virtual matrices. For instructions on
programming global presets, see the BCS commands documentation.

Entering Presets

Important: Accessing local presets may require changing the current virtual matrix
(VM); accessing global presets requires a virtual matrix setting of “99” or “999 ”.

To enter local or global presets:

Note: The following steps apply if the virtual matrix setting needs to be changed to
access programmed presets.

1. To determine the SBC's current VM, hold down the 0 key for five seconds until
the screen flares (e.g., characters briefly brighten, then repetitively dim to
normal; display never goes blank); then release key.

global presets (which can include multiple virtual matrices).

2. Local preset
If the VM number displayed is not correct, enter the number of the VM (e.g.,
enter “01” or “001” for VM 1). Wait until the display stops flashing (approx. five
seconds), then enter the local preset number . If t he display is “99” or “999”, the
VM setting must be changed to execute a local preset (see Step 3).

– indicates the SBC is currently set for executing

– if the VM number displayed is correct, enter the preset number.

Global preset
(approx. five seconds), then enter the global preset number. If the display is a
VM number, the VM setting must be changed to execute a global preset (see
Step 3).

3. Change the VM setting from local to global
the display stops flashing (approx. five seconds), then enter the global preset
number.
Change the VM setting from global to local
(e.g., enter “01” or “001” for VM 1). Wait until the display stops flashing

– if the display is “99” or “999” wait until the display stop s flashing

by entering “99” or “999”. Wait until

by entering the number of the VM

(approx. five seconds), then enter the local preset number.

Executing Switches & LED Display

When the system is powered up, the LED on the SBC Preset flashes for two seconds
and then displays the current virtual matrix number or displays “99” or “999” if it is
ready for a global preset.

The scrolling ranges for global presets are 1 to 64. For local presets, the scrolling
ranges are 1 to 99 on a 2-digit display, and 1 to 999 on a 3-digit display. If you select
an invalid local preset number (e.g., a number for which a local preset had not been
defined), the Preset SBC will display error code E2.

To operate the 2-digit Preset SBC:

Press the keys according to their function as indicated.
