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 bit = 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.

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 switch that routes the signal 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.
