System Overview System Description The Gemstar Automated Inventory Control System (AICS) is a wireless communications system that enables remote inventory tracking and asset management. This technical manual describes the system, its components and other information necessary for its regulatory approval, installation and operation. The specifications contained in this document pertain to the Gemstar GSAM Model AICS. The key to the system is a small electronic device known as a “Tag”which is attached to each finished product at the manufacturing facility. The Tag remains attached to the piece as it travels from the manufacturing facility to the distribution depot to the dealer site. Asset Tag Monitoring units called “MicroCells” detect signals from these Tags when they are on-site. Typically there are three or more MicroCells at each site to ensure complete coverage of the area. When a MicroCell detects a tag, it stores this data and reports to the site’s On-Site Controller (OSC) on demand. The On-Site Controller is connected by dedicated telephone line to the company’s host computer, the Server, typically located at the Head Office. MicroCell Inventory can therefore be tracked from the Head Office as it moves from site to site until the equipment is sold and the tag is removed, transmitting an appropriate signal to the system. On-Site Controller Revision 0 11-Sep-98 Page 1 Section 1 - System Overview Gemstar Communications Inc. Technical Summary Use and Purpose The Automated Inventory Control System (AICS) allows the user to obtain inventory data remotely from dealerships equipped with the system. The user can Poll the Server to download current data providing the following timely data of inventory equipped with Gemstar’s Tags: • inventory currently at the dealer • inventory that has been transferred to another dealer • missing inventory • sold inventoryGemstar’s MicroCell network, installed at the dealerships, monitors the tagged inventory and reports the data to a storage device or On-Site Controller (OSC). This data is accumulated and held at the OSC until the main server polls and uploads the data into its main database. The data can then be accessed by the Host user to generate the required reports. Radio Frequencies Data to be provided by UltraTech RF Power Output and Field Strength Data to be provided by UltraTech Time Lines/Duty Cycle Transmission Characteristics Asset Management Tags transmits every 15 minutes when the strap is closed for a period of 8.6 milliseconds and every 6 minutes with the strap open. Based on a maximum duty cycle of 100 milli seconds, the duty cycle for the tag is 8.71 % Power transmission on the fundamental frequency of 904.512 MHz has been measured at a peak level of 87.63 dBlV/m. Revision 0 11-Sep-98 Page 2 Section 1 - System Overview Gemstar Communications Inc. Connection Mode When the Tag Strap is first connected, the Tag will transmit a signal every two seconds for a total of twenty seconds. Normal Mode Tags transmit four times per hour on the quarter-hour plus or minus 2 minutes during normal operation. The exact timing of the transmission within those parameters is randomly generated by computer algorithm. Sold/Disconnect Mode When the Tag Strap is removed (normally upon the sale of the equipment), the Tag transmits ten times per hour for twenty-four hours. Reconnection of the Tag Strap during this time period will have no effect on the transmissions. At the end of the twenty-four-hour period, the Connection Mode is enabled should the Tag Strap be reattached. Revision 0 11-Sep-98 Page 3 Section 1 - System Overview Gemstar Communications Inc. System Block Diagram Revision 0 11-Sep-98 Page 4 Section 1 - System Overview Gemstar Communications Inc. Regulatory Approval Label Diagram The following notice label is typical of the type that must be attached to each component of the AICS: 1½” (38mm) 2½” (64mm) AICS Tag Model No. GSAM-ATB-01 FCCID: ???? IC Certification No. ?????? This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. Revision 0 11-Sep-98 Page 5 Section 1 - System Overview Gemstar Communications Inc. The following illustrations show where on the equipment the labels are to be attached: The tag notice label is affixed on the embossed area on the side opposite the Gemstar logo. The Microcell notice label is affixed on the lower rear section of the case opposite the side with the Gemstar logo. Revision 0 11-Sep-98 Page 6 Section 2 - Component Description Gemstar Communications Inc. Component Description Asset Management Tag Tag Function A microprocessor-based Radio Frequency (RF) transmitting device attached onto new vehicles during the manufacturing process. The tag is programmed to transmit a unique code, which is associated with the serial number of the inventory item in the Host computer. The attachment of the Tag is made using an integrated strap, which also provides the “status” of the Tag as well as acting as the antenna. The tag transmits its code randomly 4 times per hour under normal conditions. Once the strap is disconnected, the Tag then begins transmitting a “sold” status 10 times per hour for 24 hours and then resets itself. Revision 0 11-Sep-98 Page 7 Section 2 - Component Description Gemstar Communications Inc. Tag Model Numbers Automated Inventory Control System (AICS) Tags are identified by serial number and one of the following model numbers: GSAM-ATB-01 for basic Asset Tags; GSAM-ATP-01 for Asset Tags “Plus”. The last two digits of the model number indicate the manufacturer’s version of the device. Tag Diagnostic Lights LED NUMBER COLOR D1 RED FUNCTION Flashes every 2 sec. when transmitting. Stops flashing 24 hrs. after disconnect. Tag Attachment and Test Procedure ATTACHMENT • • • Fill out New Tag Listing Form. Attach Tag to equipment as follows: 1. Ensure the light on tag is not flashing prior to installation; 2. Loop the loose end of the strap around attachment point; 3. Plug the strap into the open connector on the tag and twist clockwise ½ turn; 4. Ensure light on top of tag is flashing approximately every 2 seconds (the light will continue to flash every 2 seconds for 20 seconds and then flash once every 10 seconds.) Fax New Tag Listing to System Operator DEMO OR REPAIRS • Leave tag attached to equipment SOLD • • • Remove strap by pushing the release lever fully to the left, pulling the strap out of the connector. (Leave the strap disconnected.) The light will start blinking once every 2 seconds for twenty-four hours. Once the light has stopped blinking, the tag will be ready to reuse.
