Introduction • About this Guide • About the DTP T USW 233 Switcher • Features About this Guide This guide describes the Extron DTP T USW 233 switching transmitter. The switcher outputs a signal to a compatible DTP receiver. This guide describes how to install, operate, and configure the switcher. NOTE: In this guide, the DTP T USW 233 is commonly referred to as a “switcher” or a “switching transmitter.
TP Cable Extron recommends XTP DTP 24 shielded twisted pair (STP) cable for best performance. Category (CAT) 5e, CAT 6, CAT 6a, or CAT 7 STP or unshielded twisted pair (UTP) cable is acceptable. Extron recommends at least 24 AWG, solid conductor, STP cable with a minimum bandwidth of 400 MHz. NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201 cable to link the switching transmitter and receiver. The DTP T USW 233 does not work properly with these cables.
Installation and Operation This section describes the installation and the operation of the DTP T USW 233, including: • Mounting the Unit • Connections and Reset Button • Operation Mounting the Unit Mounting instructions can be found in Mounting the Switcher on page 18. Compatible optional hardware is listed on the Extron website (www.extron.com). ATTENTION: • Installation and service must be performed by authorized personnel only.
c Audio input port — If desired, plug an analog audio input into the switching transmitter via this stereo mini jack connector. Analog audio is not embedded into the digital video signal. AUDIO NOTES: • The analog audio input on this connector is in addition to the digital audio that may be embedded in the HDMI inputs. See the figure at right to identify the connector tip, ring, and sleeve when you are making connections for the switching transmitter from existing audio cables.
g TALLY Remote Tally port — If desired, to remotely identify the currently selected input, plug a locally-constructed device into this 3.5 mm, 4-pole captive 1 2 3 +V screw connector. Connect the power wire for the device into the +V pin and connect the ground wire for the each indicator into the corresponding tally out pin, 1, 2, or 3.
Supported cables The DTP T USW 233 is compatible with CAT 5e, 6, 6a, and 7 shielded twisted pair (F/UTP, SF/UTP, and S/FTP) and unshielded twisted pair (U/UTP) cable. Cable recommendations Extron recommends using the following practices to achieve full transmission distances up to 230 feet (70 m) and reduce transmission errors.
Power supply wiring NOTES: • The power supply included with the switching transmitter can normally power both units. • If you have removed the ground jumpers (see Disconnecting the Ground on page 19) because of ground potential differences, one unit of the pair cannot remotely power the other unit. Each unit requires a local power supply. Figure 5 shows how to wire the connector. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
IR and RS-232 connector wiring Figure 6 shows how to wire the Remote RS-232 and Over DTP RS-232 and IR connectors. IR Device Tx Rx G Tx Rx IR OVER DTP RS-232 Tx Rx G V RS-232 REMOTE Rx Tx Gnd Tx Rx Gnd RS-232 Device Figure 6. IR and RS-232 Connectors Wiring NOTES: • The IR Tx and Rx line pair and the RS-232 Tx and Rx line pairs must each cross once between their connectors and the source or destination.
Operation Controls and Indications 3 STATUS AUTO SWITCH 1 2 1 3 2 3 SIGNAL CONFIG HDCP MODE 1 4 AUTO NORMAL 2 Figure 8. 5 DTP T USW 233 6 7 Power Indicators Auto Switch mode indicator a Auto Switch LED — When lit, indicates that the switcher is in auto-input switching mode. When unlit, the switch is in normal (manual) mode (see Selecting the switch mode on page 11).
Status LEDs g Status LEDs — Signal LEDs (1 through 3) — Indicates that the switcher detects Horizontal sync (Signal LED 1) or TMDS clock (Signal LED 2 and Signal LED 3) on the associated input. HDCP LEDs (2 and 3) — Indicates that the input signal is HDCP encrypted. Front Panel Operations The following paragraphs detail the power up process and provide sample procedures for switching inputs, changing between normal and auto-input switching mode, and toggling executive mode on and off.
Selecting the switch mode NOTE: In the auto-input switching mode that is available from the front panel, the switcher selects to the highest numbered input with a sync signal present. See the Front panel mode SIS commands on page 15 for an auto-input switching low mode, which selects the lowest numbered input. Turn auto-input switching mode on and off as follows: 1. Press and hold the Mode (Input 1) button (see figure 10). Press the and HOLD the Mode button. Press and release the Auto or Normal button.
Remote Control This section includes: • Contact Closure Control • Simple Instruction Set Control The DTP T USW 233 switcher can be remotely controlled via its rear panel Remote RS-232 port, its front panel configuration (USB) port, and its rear panel Remote Contact port.
Simple Instruction Set Control The DTP T USW 233 switching transmitter can be remotely controlled using SIS commands from a host device such as a computer or control system via its rear panel Remote RS-232 port (see item h on page 5) or front panel Configuration (USB) port (see item a on page 8).
Using the Command and Response Table The command and response table begins on the next page. Symbols are used throughout the table to represent variables in the command and response fields. Command and response examples are shown throughout the table. The ASCII to HEX conversion table below is for use with the command and response table.

Reference Information This section provides procedures for mounting the DTP T USW 233 switching transmitter and disconnecting the ground between it and a compatible receiver. • Mounting the Switcher • Disconnecting the Ground Mounting the Switcher ATTENTION: • Installation and service must be performed by authorized personnel only. • Avoid ground potential differences between the switching transmitter and receiver installation sites, which can lead to equipment damage or a missing or unstable picture.
UL Rack-Mounting Guidelines The following Underwriters Laboratories (UL) requirements pertain to the installation of the unit into a rack. • Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (TMA = +122 °F, +50 °C) specified by Extron.
3. Locate and lift off jumpers JMP1 and JMP2 (see figure 12). JMP2 JMP1 Figure 12. Jumper Locations 4. Reinstall the switcher cover, securing it in place with the screws removed in step 2. 5. Reinstall the switcher in the rack or other installation option (see Mounting the Switcher on page 18). 6. If you are using shielded cable, disconnect the cable shield from the connector at either end of the cable. 7.
