Spider IIIAR Installation 1250 South Clearview, Mesa, Arizona 85208 (480) 969-2828 Page 1 of 14 Spider IIIAR Reader Installation Instructions FCC Certification NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ! Reorient or relocate the receiving antenna. ! Increase the separation between the equipment and receiver. ! Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. ! Consult the dealer or an experienced radio/TV technician for help. Spider IIIAR Installation 1250 South Clearview, Mesa, Arizona 85208 (480) 969-2828 Page 2 of 14 Introd uction When placing the reader in a permanent position, several factors need to be considered that contribute to choosing the reader’s position. ! RF visibility ! Tag density ! Range configuration ! Access to Power ! Access to LAN communication ! Communication bandwidth ! Environmental conditions. ! Serviceability. RF Visibility RF Visibility refers to the reader’s ability to “see” the tags in its reporting area. The best condition is to have an RF line-of-sight between the reader and all tags. In most cases the Spider IIIAR’s RF line-of-sight is equivalent to a visual line-of-sight. However, there are some materials that are transparent to RF but not to light. The spider reader can read tags through a typical wall such as found in an office environment. Some walls are more transparent than others. Metal wall studs, typically grounded to the electrical system ground, absorb the tags signal. However, because there is space between studs, some signal does get through. Different walls have different RF transparencies. Because some walls are more RF transparent than others, they need to be tested to determine their RF transparency. Example: a wall composed of wood studs and gypsum wallboard is more transparent than a wall with steel studs and gypsum wallboard. Metal objects reflect or absorb RF signals; they are not transparent to RF. Example: If a tag is placed next to a metal filing cabinet, the RF signal from the tag is reflected off the filing cabinet’s metal and is seen best from the same side of the cabinet on which the tag is located. The tag can be seen from the other side of the cabinet due to the RF signal multi-pathing (reflecting off of several metal surfaces). A multipath signal is usually weaker than a direct path signal. Spider IIIAR Installation 1250 South Clearview, Mesa, Arizona 85208 (480) 969-2828 Page 3 of 14 Example: if a tag is placed inside a metal filing cabinet, the signal from the tag is reflected off the metal of the interior of the filing cabinet several times and most of the signal is eventually absorbed inside the cabinet. The tag can be seen from outside the cabinet due to multi-pathing of the RF signal that leaks out of the drawer openings of the cabinet. That tag’s signal that leaks out will be considerably weaker than if the signal were seen directly. Earth ground or a grounded metal structure actually absorbs the tag’s signal. If you place the tag or the reader on the ground, there is a very good chance you will not see the tag’s ID because the earth ground absorbs the tag’s signal. Multi-story buildings generally have grounded rebar in the floor structure of each level. The grounded rebar in the floor can be as RF absorbing as earth ground. Since the roof of one room is the floor of the room above, mounting a spider reader on or near the roof may be the same as setting it on the ground; you may not see the tag’s ID because the grounded rebar absorbs the tag’s signal. Different floors have different transparencies to RF. When planning reader placements, because some floors are more RF transparent than others, they need to be tested to determine their RF transparency. To minimize RF interference, maintain a four to six foot separation between the Spider Reader antennas and potential RF radiators such as computers, monitors, printers, wireless network access points and electronic office equipment. The local “radio noise environment” can limit the reader’s effective range. Grounded and reflective metallic structures around the reader’s antennas and/or tags affects the system’s performance. The best location for placing a reader is line of sight to the most number of tags to be being covered by this reader. Spider IIIAR Installation 1250 South Clearview, Mesa, Arizona 85208 (480) 969-2828 Page 4 of 14 Tag Density The Spider IIIAR reader can handle a limited number of tags at the same time. The optimum number of tags varies with the chirp rate of the tag, the distance between the reader and the tags, the antennas on the reader, and the range setting on the reader. For example, the reader can efficiently handle about 500 seven-second tags at a normal distribution at the same time. If the tag chirp rate goes to one second, the same reader can handle about 70 tags at the same time. If the chirp rate goes to 14 seconds, the same reader can handle about 1000 tags at the same time. If there are more tags in the area of a reader than can normally be handled, the range setting of the reader can be reduced to limit the number of visible tags to a manageable quantity. In a highly mobile tag population, transient densities need to be calculated to assure th…

In a highly mobile tag population, transient densities need to be calculated to assure that a reader is not forced past its capacity limits when a large number of tags transit its area. Example: if 500 document folders are loaded on a cart and wheeled through the area of a reader that configured for and already has 500 tags in range, this transient load will exceed the system capacity of the reader. It may be necessary to configure the reader to accept the transient tags as part of its normal load. The antenna on the reader determines the maximum read range of the reader and thereby its coverage area. The type of antenna selected for the reader can be used to control the number of tags visible to the reader. Range Selection The…

1250 South Clearview, Mesa, Arizona 85208 (480) 969-2828 Page 1 of 1 Spider Tag Battery Replacement Procedure CAUTION: during this procedure the tag electronics can be destroyed by an electrostatic discharge (ESD) during handling. The battery replacement procedure must be performed in a controlled antistatic environment. 1 – Establish a procedure to 100% guarantee the same tag case and tag circuit board are matched together after the battery has been changed. 2 – Separate the Spider Tag case by twisting a coin in the access slot. 3 – Using Anti-ESD procedures remove the tag circuit boardand lay it on the antistatic surface. 4 – Using a non-conductive tool (wooden Q-Tip handle works well) that fits under the battery holder, push the old battery out of the battery holder. 5 – Using a new coin cell battery available from RF Code, part number 05501043, push the new battery in with the “+” side on the metal battery holder and the “-” side on the circuit board. 6 – Replace the circuit board in the Spider Tag case and snap the case together. Note: return the circuit board to the same case it originally came out of, the case is identified with a label that shows the tag’s electronic identity. After the battery has been replaced, verify that the identity being transmitted by the tag is the same as shown on the case label. +
