Install the Device
The CP4-R may be mounted into a rack or placed onto a flat surface.
Mount into a Rack
The CP4-R occupies 1U of rack space. Use a #1 Phillips screwdriver to remove the required screws from the CP4-R assembly (shown in the
illustration below), and then attach the two included rack ears with the removed screws. Mount the CP4-R into the rack with four mounting screws
(not included).

NOTE: Ensure that the included SD card is seated fully in the MEMORY slot prior to powering on the CP4-R.
Observe the following when connecting the CP4-R:
• Use Crestron power supplies for Crestron equipment.
• The CP4-R may be powered with the included 24 VDC power supply or via Cresnet® network power with the NET 4-pin terminal block port.
• The included cables may not be extended.
• Connect the chassis ground lug to a known earth ground circuit (for example, building steel) to ensure that the CP4-R is grounded properly.
• Apply power after all connections have been made.

1. RS-422 transmit and receive are balanced signals that require two lines plus a ground in
each direction. RXD+ and TXD+ should idle high (going low at start of data transmission).
RXD- and TXD- should idle low (going high at start of data transmission). If necessary,
RXD+/RXD- and TXD+/TXD- may be swapped to maintain correct signal levels.
2. A ground terminal connection is recommended but not required.
