The control system can be mounted into arack or placed onto a flat surface.

Mounting into a Rack
The control system occupies 2U of rack
space. Using a #1 or #2 Phillips screwdriver,attach the two included rack ears to thedevice. Then, mount the device into the rackusing four mounting screws (not included).

Placing onto a Flat Surface
When placing the device onto a flat surface
or stacking it with other equipment, attach
the included feet near the corners on theunderside of the device.

1. RS-422 transmit and receive are balanced signals requiring two lines plus aground in each direction. RXD+ and TXD+ should idle high (going low at start ofdata transmission). RXD- and TXD- should idle low (going high at start of datatransmission). If necessary, RXD+/RXD- and TXD+/TXD- may be swapped tomaintain correct signal levels.
2. A ground terminal connection is recommended but not required.
Ground potential difference must be under ±4 V.

Connecting the Control Subnet
The control system has a dedicated Control
Subnet that is used for communication
between the control system and Crestron
Ethernet devices. This subnet allows for
dedicated communication between thecontrol system and Crestron Ethernet
devices without interferences from othernetwork traffic on the LAN.

DO Configure theControl System
The control system can be configured using
Crestron Toolbox™, the built-in, web-based
setup tool, or the front panel controls (PRO3only).

Crestron Toolbox
Use Crestron Toolbox to establish
communication and configure the controlsystem. For details, refer to the Crestron
Toolbox help file.

NOTE: The web-based setup tool isaccessible only from Internet Explorer.

In the Ethernet setup menu, there are
additional options:

NOTE: If a security warning is displayed,click Install to continue.

• Click Advanced Settings to
specify DNS servers, web server
settings, and SSL settings.

3. Click Setup to display the control
system’s setup menu. The control system
displays the IP address, hostname, andMAC address of the device. It also allows
access to various setup and programming
screens.

• Click Ethernet Diagnostics totest Ethernet communications.

Web-Based Setup Tool2. Use Internet Explorer ® to navigate to
http://xxx.xx.xx.xxx/setup, where xxx.
xx.xx.xxx is the IP address of the control
system. The control system’s welcome
screen is displayed.

• Diagnostics displays information
about the connected devices,
hardware configuration, and error
logs.

• Click MyCrestron Dynamic
DNS to configure the
myCrestron.com Dynamic DNS
service.

• Click Reboot to reboot thecontrol system.

1. Use Crestron Toolbox to set the time zone.
For details, refer to the Crestron Toolbox
help file.

• Input/Output Control configures theCOM ports, operates the relays, andmonitors the Versiports.

• Application Setup selects programs
to be loaded on startup and controls
which program(s) are running.

4. From the control system’s setup menu,
click the following options to configure thecontrol system:• Ethernet Setup configures thecontrol system’s Ethernet settingsand displays DHCP, hostname, IPaddress, subnet mask, default router,domain, and MAC address settings.

• About displays firmware information.
Clickto return to the previous screen.

Front Panel Controls (PRO3 Only)
Use the Nav Pad and LCD display to configure
and monitor the PRO3’s operations. For details,
refer to the supplemental guide (Doc. 7330) atwww.crestron.com/manuals.
