Technical Manual Wireless CAN Bridge 500 (CB-500) Matric Technical Manual 185-XXXX, V1 Page 1 of 11 Description: The Wireless CAN Bridge functions as a wireless link that transfers CAN messages. Using the Wireless CAN Bridge, nodes on either side of a wireless link can communicate at a typical separation of 500 feet. A full 64 node DeviceNet* can be implemented depending on scan rates and frame density. Since actual CAN messages are transferred, the Wireless CAN Bridge supports any type of CAN bus standard including CAN Open and CAN Kingdom.

The effectiveness of the CAN Bridge in any particular application depends on network loading (including bursts). The loading on a CAN based network is effected by a number of factors including: polling rate of the network scanner, node count, and change-of-state activity. According to ODVA, 30% loading is recommended for DeviceNet systems employing change-of-state devices and 80% loading is recommended for polled DeviceNet systems. Heavily loaded systems increase the probability that CAN messages will be discarded due to RF bandwidth limitations. The transfer rate of 1200 fps is based on a typical scenario of 500 feet separation without significant RF obstacles. The actual transfer rate in any application is dependent upon the quality of the RF link. Structural components such as steel walls or decking, earth tunnels, and metal equipment can effect the quality of the RF link. Also, radiation sources such as other radio systems, high power switching, and magnetic fields can effect the quality of the RF link. A site assessment should be performed at any site where a new RF control is to be installed. The Wireless CAN Bridge provides a point-to-point data transfer in order to achieve the required throughput over the wireless link. A system requiring multiple wireless links can accomplish this using multiple pairs of the Wireless CAN Bridge. Up to three CAN Bridge pairs can be operated in close proximity in most situations. To operate in close proximity, use channels with the widest possible separation (channels 0, 7, and 14). System integrators must be aware of potential Near / Far problems and the complexity related to operating DSSS radios in such installations. Also, the number of radio pairs that can be operated in proximity is dependent upon the actual distances between radios. Refer to the installation section for details regarding radio issues, site assessment, and optimal antenna placement. The rate at which CAN frames are received and transmitted by the Wireless CAN Bridge falls within the timing constraints of Bosch CAN Standard 2.0b. While meeting network requirements for data link and higher levels of communication, the time required for retransmission may still have an effect on the overall timing of a control system.

RF Exposure Evaluation Document 8862-MPE FCC ID: K5B-CB500 IC: 3926A-CB500 RF Exposure Test Report Washington Laboratories, Ltd September 2005 1 Maximum Permissible Exposure Evaluation for FCC ID: K5B-CB500 IC: 3926A-CB500 1.0 Introduction This report has been prepared on behalf of Matric Limited Model: CAN Bridge 500 to show compliance with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: ƒ Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. ƒ Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. ƒ Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this test report the Matric Limited CAN Bridge 500 with 0dBd whip antenna is classified as a “Mobile Device” and the MPE will be evaluated at the 20cm test distance. Document 8862-MPE FCC ID: K5B-CB500 IC: 3926A-CB500 RF Exposure Test Report Washington Laboratories, Ltd September 2005 2 The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/ Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: ƒ Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. ƒ General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limits apply to these devices. Since there are no warnings or training associated with this unit and it can be used by anyone, the Matric Limited CAN Bridge 500 is evaluated to the General Population/Uncontrolled Exposure limits. 1.2 Radio Frequency Radiation Exposure Evaluation The highest RF output power of the unit was measured at -7 dBm at 2405 MHz. According to §1.1310 of the FCC rules, the power density limit for General Population/Uncontrolled Exposure at 2405MHz is 1mW/cm 2 . As this is a mobile device the MPE shall be calculated at 20cm to show compliance with the power density limit. The following formula was used to calculate the minimum safe distance: Document 8862-MPE FCC ID: K5B-CB500 IC: 3926A-CB500 RF Exposure Test Report Washington Laboratories, Ltd September 2005 3 2 4R PG S π = Where: S = Power Density P = Output Power at the Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna For this device, the calculation is as follows: R = 20cm P = Output Power = 0.2 mW G = Worst Case Gain = 2.15dBi = INVLOG(2.15/10) = 1.64 )20( 4 )64.1()2.0( 2 ×× × = π S = 0.000065 mW/cm 2 (Based on continuous transmission) Based on continuous operation at 100% on time the CAN Bridge 500 is compliant with the Power Density limit at 20cm.
