Extron 12G HD-SDI 101 Cable Equalizer
Introduction
This guide provides instructions for an experienced installer to set up and operate the Extron 12G HD-SDI 101, a cable equalizer for SDI, HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI digital video. The Extron 12G HD-SDI 101 is a 1 input, 1 output HD-SDI signal equalizer that can recondition and equalize digital video signals up to 12G-SDI due to losses incurred from long cable runs. The equalizer is typically placed at the end of a long cable run.
Installation
Mounting the Unit
Mounting instructions can be found in Mounting the Equalizer on page 3.
Compatible optional hardware is listed on the Extron website
(www.extron.com).
ATTENTION:
Installation and service must be performed by authorized personnel only.
Connections and Indicator
Rear Panel
- A Power connector — Connect the provided external 12 VDC, 6 watt power supply to this 2-pole, orange, 3.5 mm captive screw connector. See Power Connector Wiring on the next page.
- B HD-SDI input — This female BNC connector accepts an HD-SDI input.
The maximum length from the signal source to the 12G HD-SDI 101 input varies, dependent on the input: Format| Max. length| Format| Max. length
---|---|---|---
12G SDI| 230 feet (70 m)| HD-SDI| 787 feet (240 m)
6G SDI| 295 feet (90 m)| SDI| 984 feet (300 m)
3G SDI| 590 feet (180 m)|
NOTE: The maximum signal transmission distance depends on signal resolution, the source, the display, and the quality of the cable.
- C HD-SDI output — This female BNC connector provides an equalized and reclocked HD-SDI output Front Panel
- D Power LED — The LED lights green when the unit is receiving power.
Power Connector Wiring
Figure 2 shows how to wire the connector. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
CAUTION:
- The wires must be kept separate while the power supply is plugged in. Remove power before wiring.
- The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
- Any longer and the exposed wires may touch, causing a short circuit between them.
- Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws.
- Do not tin the power supply leads before installing them in the connector. Tinned wires are not as secure in the connector and could be pulled out.
ATTENTION:
- If not provided with a power supply, this product is intended to be supplied by a UL Listed power source marked “Class 2” or “LPS”, rated output 12 VDC min. 0.1A. Always use a power supply supplied by or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product.
- Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities.
- The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently fixed to a building structure or similar structure.
- Power supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply and the unit. The ridges on the side of the cord (see figure 2 on the previous page) identify the power cord negative lead.
To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.
Mounting the Equalizer
ATTENTION:
Installation and service must be performed by authorized personnel only.
The 1-inch high, eighth-rack width 12G HD-SDI 101 cable equalizer can be placed on a table, mounted in a rack, or mounted under a desk or table.
Tabletop Use
Affix the included rubber feet to the bottom of the unit and place it in any
convenient location.
Mounting Kits
Mount the unit using any optional compatible mounting kit listed on the 12G HD-SDI 101 product page at www.extron.com, in accordance with the directions included with the kit. For rack mounting, see “UL rack-mounting guidelines” below.
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.
- Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
- Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
- Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
- Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as use of power strips).
Troubleshooting
If no image appears:
- Ensure that all devices are plugged in and powered on. The equalizer is receiving power if its power LED is lit.
- Ensure an active input is applied to the equalizer.
- Ensure that the proper signal format is supplied.
- Check the cabling and make corrections as necessary.
- Call the Extron S3 Sales & Technical Support Hotline if necessary. See the Extron website for the Extron office nearest you.
