Quick Start Guide

Attaching Input & Output Cables/Wires

Before connecting all input and output cables/wires, att ach only the first two input s and
outputs and execute a test switch ( see “Complet ing the In st allation,” next pag e). When
the test switch is successful, attach the rest of the input and output cables and wires.

500 MHz Video & Hi-Z Sync Connectors – BNC

Five connectors are required to route an RGBHV signal. FIG. 3 shows five BNC cable
connectors attached for routing R, G, B, H, and V signals to the destination device
through Output 8. Input cable connectors are attached in the same way.

FIG. 3 Five BNC connectors are required for an RGBHV signal

Stereo Audio Connectors – 5-Term

Precis SD models featuring stereo audio have 5-position terminal block connectors
that can be wired for balanced (differential) or unbalanced (single-ended) audio
(FIG. 4).

FIG. 4 5-Term stereo audio wiring

Note: When using shielded twisted-pair wire, connect the shield (ground) at one end

only (recommend receiving end) to minimize low frequency noise (see FIG. 5).

Source and destination devices require either balanced or unbalanced connections.
More than one of the options shown in FIG. 5 can be used in the same system.

Installation

Rack Mounting

To rack mount a Precis SD enclosure:

1. Attach the rack ears as shown in FIG. 2 (screws provided).

2. Install in a rack leaving a minimum of one empty rack unit above and below
(required); three empty rack units above and below are recommended.

FIG. 2 Attach rack ears to sides of enclosure

Establishing External Control (if applicable)

The Precis SD can be controlled by attaching an external control de vice/syst em to the
CONTROL port or to the REMOTE port, which uses AutoPatch XNNet protocol for
AMX AutoPatch devices.

Serial Control (PCs, AMX Control Devices, & third-party controllers)

Use the pinout in FIG. 6 when connecting a PC to the CONTROL port.

1. Plug the null modem cable into the enclosure’s CONTROL port (FIG. 7).

FIG. 7 Attach null modem serial cable

2. Plug other end of the cable into the serial port on the serial controller/device.

3. Open serial communication software and set port settings to match the
Precis SD default settings (baud rate = 9600, data bits = 8, stop bi t = 1,
parity and flow control = none).

XNNet Control (SBCs, remote control panels, etc.)

Communication Cable Requirements:

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

• Maximum cable length: 1,000 ft. (305 m) total, including linked devices

On large control networks, termination may be required on the last linked device;
for termination information, see the device’s documentation.

To establish external XNNet control:

1. Attach XNNet link cable to XNNet device according to the device instructions.

2. Unplug the REMOTE connector on the Precis SD and loosen the screws.

3. Insert XNNet link cable wires according to FIG. 8 (either wire can be inserted in
either outside slot).

4. Tighten screws and plug in the REMOTE connector.

Control Options Startup & Test Switch

Control Panel (front or remote) – when power is applied, the Power LED on the

front illuminates.

FIG. 9 Precis SD front control panel (with audio control)

To disconnect the default switch
mode. Press the All Level Key, which illumi nates. Press Input Key 1, which flashes.
After a moment, all Output Keys illuminate. Press each Output Key; as each key
turns off, the output is disconnected from the input.
To execute the test switch
Press the All Level Key, which illuminates. Press Input Key 1, which flashes. Press
Output Key 2. When Output Key 2 illuminates, the switch is successful.

AMX Control Devices – the Precis SD is compatible with a number of

AMX control devices. For specific control programming information, contact your
AMX representative.

APControl 3.0 – install and open the program. From the APControl Launchbar

menu, select System / New; select Heritage System / Next; select Manual
Configuration Entry / Next; enter VMs and number of inputs and outputs; click Add
VM / Next; finish Wizard instructions.

To disconnect the default switch
crosspoints.
To execute the test switch
click on the crosspoint for Input 1 / Output 2.

APWeb – connect the APWeb Module (see the APWeb Module documentation and

Quick Start Guide). For instructions on disconnect ing the default switch and
executing a test switch, see the APWeb (Interface) documentation on the CD.

BCS Commands (HyperTerminal) – when power is applied, a short splash screen

appears.
To disconnect the default switch
When DL0I1T appears, the command is successful.
To execute a test switch

When CL0I1O2T appears, the switch is successful.

Applying Power

Important: We recommend attaching all power cords to a surge protector and/or an
AC line conditioner.

To apply power:

1. Attach power cord and plug into power source (turn on power source if
necessary). The Power Indicator on the front of the enclosure illuminates.

2. Apply power to any external devices (remote control panels, etc.) and then to
the source and destination devices.

Completing the Installation

The Precis SD ships from the factory with a default swit ch that rout es the signa l from
Input 1 to all outputs. Before using the system for normal operations, disconnect the
default switch and execute a test switch to verify that the system is working correctly.

To complete the installation:

1. Disconnect the factory default switch.

2. Execute a test switch that routes Input 1 to Output 2 using one of the following
control options (right column). (RGBHV signals require five connectors; all
cables for that signal must be attached for the test switch.)

3. Attach remaining source and destination devices.
