Quick Start Guide
AutoPatch Single Bus Controllers
Overview
Single Bus Controllers (SBCs) are control devices programmed to route any
input (source) to one assigned output (destination). SBCs are available in 3-Key and
12-Key models and are compatible with any AMX AutoPatch Distribution Matrix with
an XNNet compatible interface.
General Specifications
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
(customer supplied). For other installations, see Steps 9 through 11 before mounting
the SBC.
Important: If installing multiple SBCs, see the section on linking (on reverse) before
mounting SBCs in boxes.
Mounting & Wiring the SBC
Power Requirements
•
+9 VDC @ 120 mA per 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 enclosure’s CPU). For
exact CPU location and instructions for attaching a link cable, see router
documentation.
3.
Route the link cable from the enclosure through the holes in the single-gang box.
4.
Attach power cable wires to the power source.
5.
Route power wires from power source through the holes in the single-gang box.
6.
Snap the bezel on the SBC.
7.
Carefully pierce the two gray circles near the top and bottom of the SBC
faceplate that indicate the mounting holes (if not ordered pierced).
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 SBC power connector P3.
For the 2-digit SBC, use Steps 9a and 9b.
For the 3-digit SBC, use Steps 9c through 9e.

3-digit SBC
Wiring the Link Connector (P4 or P5)
Wire the SBC Link connector, either P4 or P5. Steps 10 and 11 apply to both the 2-digit
and 3-digit SBC.
10.
Loosen the two outer screws of the link connector (P4 or P5) on the circuit board
on the rear of the SBC (FIG. 3 left for 2-digit SBC; FIG. 3 right for 3-digit SBC).
11.
Insert XNNet link cable wires into link connector. Either wire goes into either
outside slot.
Tighten screws.
12.
Insert screws through mounting holes on SBC faceplate and holes on
single-gang box (FIG. 2) and tighten.
