Setup 
Network Wiring 
When wiring the DM network, consider the following: 
NOTE: DMNet wiring and Cresnet
®
 wiring are not compatible. 
•  Use Crestron Certified Wire. 
•  Use Crestron power supplies for Crestron equipment. 
•  Provide sufficient power to the system. 
•  For DigitalMedia CAT wiring, use DM-CBL DigitalMedia Cable. Up to 
two DM Repeaters (model DM-DR, sold separately) may be required. Refer 
to the latest revision of the Crestron DigitalMedia Design Guide (Doc. 
4789) for complete wiring guidelines. 
CAUTION: Insufficient power can lead to unpredictable results or damage 
to the equipment. Please use the Crestron Power Calculator to help calculate 
how much power is needed for the system (www.crestron.com/calculators
). 
For more details, refer to “Check Network Wiring” which starts on page 22. 
Identity Code 
NOTE: In the SIMPL™ Windows program, when the DM-TX-200 is dropped onto 
an input card of a DM switcher, its IP ID is assigned automatically and does not 
require additional programming or configuration. Use the information below when 
the DM-TX-200 is dropped directly into an Ethernet slot on the control system in 
SIMPL Windows, without a DM switcher. 
The IP ID is set within the DM-TX-200’s table using Crestron Toolbox. For 
information on setting an IP table, refer to the Crestron Toolbox help file. The IP IDs 
of multiple DM-TX-200 devices in the same system must be unique. 
When setting the IP ID, consider the following: 
•  The IP ID of each unit must match an IP ID specified in the SIMPL 
Windows program. 
•  Each device using IP to communicate with a control system must have a 
unique IP ID.
