Revised: January 12, 2012, OL-24695-01

The Cisco TelePresence System TX1300 47 is designed to be used in a multipurpose room (for example, a conference room). However, to ensure that you have the best conferencing experience, Cisco recommends that you optimize your room by using the guidelines and recommendations in this chapter.

This chapter includes the following sections:

•General Room Requirements and Recommendations.

•Supported Table Types and Minimum Room Dimensions

•Recommended Table Height

•Recommended Table Finishes

•Lighting Recommendations

•Acoustic Recommendations

•Power Requirements

•HVAC Considerations

•Auto Collaboration Data Display

General Room Requirements and Recommendations

The following are required elements for a TX1300 47 room:

•You must use an enclosed space.

•You must have a room with the minimum dimensions that are specified in the "Supported Table Types and Minimum Room Dimensions" section.

•The room must meet minimum heating, ventilation and air conditioning (HVAC) requirements that are provided in the "HVAC Considerations" section.

•The room must be supplied with electrical power as specified in the "Power Requirements" section.

•If you install two TX1300 47 systems in rooms that share a wall, you must not mount the systems on the same wall; mount the two TX1300 47 systems on separate walls.

The following recommendations or guidelines ensures that you have the best possible conferencing experience:

•A white room is acceptable but not recommended for the best experience. Neutral colors work best for the floors and walls.

You can use color, décor, and signage in the room to communicate your brand and corporate identity.

Cisco recommends that you do not use colors with high contrast.

•Normal office lighting is usually sufficient for a good conferencing experience. However, Cisco recommends that you perform the following actions for the best experience:

–Use indirect florescent lighting and avoid any direct lighting.

–If your room has windows, install shades to reduce glare, especially for any windows that are directly behind the participants.

For more information about lighting, see the "Lighting Recommendations" section.

•The TX1300 47 was designed to work in an office with normal sound levels. Large rooms, or rooms with high ceilings, can cause echo and reverberation issues. For more information about acoustics, see the "Acoustic Recommendations" section.

Supported Table Types and Minimum Room Dimensions

Figure 1-1 through Figure 1-10 show the types of tables that the TX1300 47 supports and the minimum room size for each type of table. Figure 1-2, Figure 1-4, Figure 1-8, and Figure 1-10 show tables with additional microphones that can be used with an audio-only conference.

Recommended Table Height

For all table types, the table must be 28 to 32 inches (71 to 82cm) high. 30 inches (76 cm) is the optimal table height.

Recommended Table Finishes

Cisco recommends that the table in your TX1300 47 room have the following characteristics:

•The table tops should have a low-gloss finish (non-reflective surface)

•If you use wood a table, the wood should be a neutral, light color

•If you use a laminate or plastic table, the table top should be a neutral, light color (for example, off-white or light gray)

Cisco does not recommend using the following types of table tops:

•A table that uses a very dark or heavily saturated color (for example, wood that is reddish in color, or uses a dark wood stain)

•A table with a glass top

•Any table top that has a reflective surface

Figure 1-11 shows examples of unacceptable table colors.

Figure 1-11 Unacceptable Table Color Examples

Lighting Recommendations

The cameras that are used in the TX1300 47 are designed to work well using normal office lighting. However, Cisco recommends that you use well dispersed, ambient light throughout the room.

The ideal lighting environment is to use indirect fluorescent lighting that uses bulbs with a rating of 4,100 Kelvins (4100k). You can supply the lighting either through recessed fixtures or pendant fixtures. Pendant lighting is best if your room is more than 9 feet (2.7 meters) high. Cisco does not recommend direct lighting.

For best results, one set of lighting should be in front of conference participants, and one set should be behind the participants.

The lighting in the room should be well controlled. You should block natural sunlight or other light that could enter through glass or thin blinds.

Cisco strongly recommends that your fluorescent lighting use electronic ballasts.

It is important to consider the direction of the lighting in your room. For conferencing purposes, lighting can come from three directions:

•Key Light—This is the primary source of lighting and typically the strongest source of lighting. Key light is built-in to the TX1300 47 light reflector.

•Fill light—This light is created primarily from the overhead lights in the room, and secondarily from the TX1300 47 light reflector. Fill light can reduce or eliminate shadowing on the conference participants that is created by the key light.

•Back light—This optional light is projected behind the conference participants. Back light is generally indirect and creates separation between the participants and the room background.

If measuring light in the room, the light range should be between 250 and 800 lux.

For specific lux measurement specifications, see Table 1-1.

Table 1-1 Lighting Measurement Recommendations

Illumination	Target Measurement in Lux (= lm/m2)	Tolerance	Notes
Overall illumination	300-400 lux	50 lux All lighting should be evenly dispersed. There should not be areas of 250 and 450 lux in the same room.	Measured vertically with the light sensor pointed at wall or intended camera location (not pointed at the ceiling).
Shoulder light/Direct down light	600-700 lux	Generally, shoulder lighting should not be more the 400 lux greater than the overall illumination of the room, and should never exceed 800 lux	Measured horizontally at table height, with the light sensor pointed at the ceiling

Acoustic Recommendations

The TX1300 47 microphones and speakers are designed to be used in rooms that have typical office noise levels.

Rooms with excessive noise (greater than 55 decibels (dBA) might not provide the best conference experience.

Large rooms, high ceilings, or rooms that have a large amount of glass may experience reverberation. If possible, reduce reverberation to a level that is below 700 milliseconds across the voice spectrum (between 300 and 3000 Hertz).

Power Requirements

The Cisco TelePresence System TX1300 47 requires one 20amp circuit @100V 120V (US electrical code requires maximum 16amp on a 20amp circuit) or one 10amp circuit @ 240V. Two receptacles must be provided for these circuits. The receptacles should be located on the wall near the intended location of the endpoint.

---

Note Peripherals such as document cameras or alternate displays will require additional circuits and receptacles. Placement will depend on the type and location of the peripheral device.

HVAC Considerations

Planning the cooling for a TX1300 47 TelePresence room is important to insure the room remains comfortable for participants and the equipment is kept safe. As outlined in the overview section of this document, HVAC considerations should be given from the initial phase of choosing a room. The detail in the table below outlines the specific BTU output of a TX1300 47 when deployed as recommend and under typical operating conditions. Typical assumes normal usage conditions such that the system is not subject to 100 percent utilization rates and deployment following Cisco recommendations. i.e. room located on interior, proper air circulation, walls painted with neutral colors, temperature expected 72-76 degrees F. Within these guidelines and typical usage, diversity of 25 percent can be equated which lowers cooling requirements and increases overall efficiency. HVAC considerations should be given from the initial phase of choosing a room. Installing new cooling (or heating) systems can be time-consuming.

---

Note Conditions not consistent with these recommendations or typical usage may require additional cooling. Consult with an HVAC engineer to define building envelope and unique requirements. Additional equipment such as data displays, document cameras, etc. will require additional cooling.

Auto Collaboration Data Display

The Cisco TelePresence System TX1300 47 ships with one unique output port that supports only one display of data shared from other CTS endpoints. This port supports standard HDMI connectors and cables. If you wish to connect more than one display for sharing data or presentations, it is necessary to purchase an HDMI splitter and connect it to the Auxiliary control unit port.

Note The high frame rate codec does not support 30 frames/sec in presentation-in-picture (PIP) mode. An external display is recommended.

The supported output resolution is 1024x768 at 50/60 Hertz and is supported by all Cisco LCD displays. Third-party displays which support these specifications may not be compatible. The HDMI to DVI cable for the data display has to be purchased by the customer.
