Communications Using Crestron Toolbox Software
Crestron Toolbox software enables communications with the DM-TX-201-C.
Communications with the DM-TX-201-C can occur in the following ways:
lVia a DM switcher (DM-MD8X8, DM-MD16X16, or DM-MD32X32)
lVia the LAN port of the DM-TX-201-C. In this scenario, the DM-TX-201-C is used in a
stand-alone configuration in which it does not connect to a DM switcher.
Communications via a DM Switcher
Communications with the DM-TX-201-C can be accomplished using USB or TCP/IP
communications between a PC running Crestron Toolbox software and a DM switcher.
NOTE: TCP/IP provides a faster method of communications than USB and is required
for operation with a Crestron control system.
Using USB Communications
Use Crestron Toolbox software to establish USB communications between a PC and a DM
switcher.
NOTE: The Type A to Type B USB cable included with a DM switcher connects the USB
port on a PC to the COMPUTER port on the DM switcher.
USB Communications via a DM Switcher
To establish USB communications between a PC and a DM switcher, do the following:
1. Using the Address Book, create an entry using the USB communications protocol.
When multiple USB devices are connected, identify the DM switcher by entering
information into the following text boxes:
lModel: Enter the model name (DM-MD8X8, DM-MD16X16, or DM-MD32X32)
of the DM switcher.
lSerial: Enter the serial number of the DM switcher.
lHostname: Enter the hostname of the DM switcher.

6 • DM-TX-201-C Supplemental Guide — Doc. 6958E
NOTE: The hostname can be found in the System Info window in the
section marked "Ethernet;" however, communications must be established
in order to see the hostname in the System Info window.

NOTE: In a stand-alone configuration, DHCP is enabled by default. If desired, the
default IP address can be assigned by holding down the SETUP button while
applying power. The default IP address, which is 192.168.1.236, overwrites the
current setting and remains until it is changed.
2. Using the Address Book, create an entry for the DM-TX-201-C using the TCP
connection type, and then enter the IP address.
3. In the Crestron Toolbox toolbar, click . The System Info window opens.
4. In the drop-down list at the bottom of the System Info window, select the entry of
the DM-TX-201-C. Device information is displayed.
