SMD 101 • Setup Guide (Continued)

Output Connections

BHDMI output – Connect an HDMI (or DVI with suitable adapter) display device to the HDMI output connector. The EDID of a connected display is read and the output automatically configured. For non-standard displays or devices, see the SMD 101 User Guide for additional output resolutions and format settings.

CAudio output – Connect a balanced or unbalanced stereo (or dual mono) line level audio device to this 5-pole 3.5 mm captive screw connector (see figure 1, C on the previous page). Wire the connector as shown in figure 3, below.

ATTENTION: For unbalanced audio, connect the sleeves to the ground contact.

DO NOT connect the sleeves to the negative (–) contacts.

NOTES:

•The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inch (5 mm). If longer, the exposed wires may touch, causing a short circuit between them. If shorter, the wires can be easily pulled out even if tightly fastened by the captive screws.

•Do not tin the wires. Tinned wire does not hold its shape and can become loose over time.

Control System Connections

The SMD 101 can be configured and controlled from the RS-232 port or the front panel mini-type B USB config port using DataViewer, or from the LAN port using a standard web browser. Since the LAN port must be connected for streaming source input, Extron recommends also using it for configuration and remote control of the SMD 101.

DIR In – Connect an (optional) IR receiver to this 3-pole 3.5 mm captive screw connector to extend the range of the IR hand control. The optional IR hand control provides access to the on screen menus for configuration and direct control over playback.

ERS-232— Connect the host RS-232 cable to the rear panel (see right) with a 3-pole captive screw connector for bi-directional (±5 V) serial host control or IP pass‑through. The default protocol for this port is 9600 baud rate, no parity bit, 8 data bits, 1 stop bit, and no flow control (handshaking).

FReset button and LED — The SMD 101 has three reset modes to return user-defined configuration settings or all settings back to factory defaults. The LED indicates the desired reset mode, and provides the reset status during the reset operation. For information on using the reset mode, see the SMD 101 User Guide.

GRJ-45 Ethernet connector (LAN) — Use a standard Ethernet cable to connect to a network (see right). The table at right has the default network settings.

NOTE: To connect the SMD 101 directly to a computer Ethernet port, use a crossover Ethernet cable.

The ACT (amber) LED indicator on the LAN connector blinks in a pattern to indicate the connected network speed.
