Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Chapter 2 Overview This chapter provides an overview of the APCC and its additional components. The chapter also describes the contents of a product shipment. Access Point Controller Card (APCC) The Sensys Networks VDS240 Wireless Vehicle Detection System detects the presence and movement of vehicles with magneto-resistive sensors mounted in the pavement. Wireless sensors continuously transmit detection data to the APCC that collects and forwards data to remote traffic management systems or local traffic signal controllers such as the CalTrans Type 170, Type 2070 ATC and NEMA TS-1, and TS-2 controllers. The Sensys Networks Access Point Controller Card (APCC), is a second generation controller card that maintains low power consumption, supports multiple radios, and allows for additional communication and processing power. The APCC, which is compatible with all of Sensys Networks VDS240 Wireless Vehicle Detection System products, receives and processes data from the sensors. The APCC then relays the sensor detection data to a roadside traffic controller or remote server traffic management system. Contact Closure Expansion Card Additional capacity (to handle more sensors or controller channels) is provided by a contact closure expansion card (EX card). EX cards use the same form factor as APCC cards and are daisy-chained to a CC interface on the APCC on the frontpanel RJ45 jacks or backplane connectors. Up to 63 EX cards can be used per APCC card. Sensys Networks, Inc. Access Point Controller Card (APCC) Installation Guide Chapter 2 Types of APCC Configurations The APCC single-slot configuration consists of dual APCC radio ports, Sensys Networks Expansion (EX) port, and contact closure interface via backplane to a traffic controller. It also has dual USB 2.0 full speed host ports and 10/100Base-T network access. The APCC dual-slot configuration adds an SD memory card, realtime battery-backed clock, dual serial (DB9) interface, or an optional built in cellular modem. Figure 2.1. APCC configurations APCC System The minimum APCC system consists of an APCC and one SPP radio. The system can also consist of multiple SPP radios and an isolator that offers electrical isolation up to 1500V, surge protection up to 1500V, and AC power cross protection. Figure 2.2. APPC system configuration Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Overview APCC Serial Port Protocol (SPP) Digital Radio The APCC, along with the SPP, maintains two-way wireless links to an installation’s sensors and repeaters, establishes overall time synchronization, and transmits configuration commands and message acknowledgements. Figure 2.3. SPP digital radio Isolator The isolator is an optional component that provides the following services: connects an SPP to the APCC isolates and routes power from the controller backplane to the SPP extends the communication for the APCC to and from the SPP at RS422 distance.

Contact closure card functions can be configured from the switches on the front panel eliminating the need for a laptop PC and TrafficDOT. Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Chapter 3 APCC Installation Considerations This chapter provides the installation considerations for the APCC. Prior to installing an APCC ensure that the following aspects have been considered in the site design. 1. Identify the devices that will be used with the APCC (refer to Identifying the SPP and Sensors). 2. Determine the configuration of the APCC (refer to Determining the Device Configuration). 3. Determine the number of available slots in the traffic controller's detector shelf and which contact closures are required (refer to Determining Slots and Contact Closures). 4. Develop the sensor-to-contact closure card mappings (refer to Mapping Wireless Sensors to Contact Closures). Identifying the SPP and Sensors SPP Each APCC must connect to an SPP. This connection supplies power to the SPP and passes command and configuration data to/from the APCC. There is a one-toone relationship between the APCC and master cards in a network. Determine the location of the SPP relative to the cabinet that will hold the APCC card. The Cat5 cable that connects to the SPP to the APCC, via an isolator, must meet standard length limitations (2,000 ft with isolator) for RS422 communication. Sensys Networks, Inc. Access Point Controller Card (APCC) Installation Guide Chapter 3 Wireless Sensors Each channel of an APCC interfaces a designated set of sensors to a designated contact closure. Ensure information describing which sensor (or sensors) will actuate a given APCC is available. NOTE: Wireless sensors have a unique identifier known as the Sensor ID. Use this identifier to refer to sensors in design notes and plans. Determining the Device Configuration Configuration of an APCC is based on the following design decisions: The number of APCC channels enabled The operating mode (pulse or presence) of each channel The use of and settings for any optional elements that modify the behavior of channels operating in presence mode The channel status communication method (LED-only) used by each channel Configuration Worksheet Each APCC supports up to four channels that are separately configured. Design decisions can be captured in a Channel Configuration Worksheet such as the one shown below. NOTE: Default values are shown in bold. Configuration Element Example Data Options 1. Card identifier (Defined by the traffic controller or installer) 2. Channel 1, 2, 3, 4 3. Channel State Enabled | Disabled Enabled 4. Channel Mode Pulse | Presence Presence 4a.

Channel configuration worksheet with example data (default values shown in bold) Notes 1. Contact closure cards are addressed by the Card ID, a value dictated by the controller or supplied by the installer. 2. Complete one worksheet for each channel. 3. Channel Holdover Setting should not be used; set it to zero. 4. The items listed in the section Other Information are not part of APCC configuration. They are relevant to other aspects of installing and operating the APCC. Determining Slots and Contact Closures Configuration of contact closure cards depends on (i) the availability of open slots on the controller backplane and (ii) the use of any predefined functions or phases for each slot – such as in the case of a standard CalTrans 322 shelf, where one contact closure card and three contact closure EX cards are required (one card per phase). Typically, a site survey of the traffic controller is required. Shelf and slot information from the controller are used to create an identifier, known as the Card ID, that uniquely defines an APCC in the network. IMPORTANT! If using an APCC with an I/O board, it is essential that there is an empty slot directly to the left of the APCC. Sensys Networks, Inc. Access Point Controller Card (APCC) 11 Installation Guide Chapter 3 Mapping Wireless Sensors to Contact Closures The final installation consideration for contact closure cards are the assignment of sensors to specific channels. The four channels represent independent contact closures which, in turn, are actuated by the vehicle detection events transmitted by a defined group of wireless sensors. Each sensor may be associated with zero or one Card ID/Channel combinations. Up to 15 wireless sensors can be associated with the same card/channel, in which case the sensors are logically “OR-ed” together – meaning that if any sensor on the channel detects a vehicle, the corresponding contact closes. The sensor-to-contact closure channel mappings are stored in a sensor database that resides in memory. The sensor-to-contact closure channel mappings are maintained within TrafficDOT. Defining the channel mappings is aided by the use of a Channel Mapping Worksheet such as the one shown below. Card ID Channel (1 - 4) Sensor ID Channel Extension (opt.) Location / Lane / Description (opt.) 3-02 06C2 East bound, lane 1 3-02 06C3 East bound, lane 2 3-05 14C7 Advance C.3 3-06 0404 Stop bar A1 3-15 05D7 West bound, lane 1 Table 3. Sensor-to-channel mapping worksheet with sample data Notes 1. The worksheet assumes one sensor per row. Use as many rows as necessary to assign all necessary sensors to channels. 2. Do not duplicate Sensor ID values. (A wireless sensor may only be assigned once.) 3. The sample data above depicts representative Card ID values. Since these values are rarely known prior to field installation, substitute a place-holder value so that the installer will understand how the wireless sensors are allocated to the channels. 4. Values for Channel Extension and Location are optional. 12 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Chapter 4 SPP Installation Considerations This chapter provides the installation considerations for the SPP. Prior to installing the SPP, ensure that the following aspects have been considered in the site design. Powering the SPP Collecting Data From the APCC Determining the Location of the SPP Each consideration is discussed below. In addition, refer to the Sensys Networks Wireless Vehicle Detection System Reference Guide, Design Guidelines for Freeway Applications, and Design Guidelines for Intersection Applications for more information. Powering the SPP The overall network design determines how the SPP is powered; two general models are supported: Acquiring power directly from a traffic controller cabinet Acquiring power from a traffic controller using optional isolator Acquiring Power From a Traffic Controller An SPP can be directly interfaced to a traffic signal controller through an APCC. When this is the case, power to the SPP is drawn from the traffic controller as shown in the following figure. Sensys Networks, Inc. Access Points Controller Card (APCC) 13 Installation Guide Chapter 4 Figure 4.1. SPP radio powered from a traffic controller Acquiring Power From Traffic Controller Using an Isolator An optional isolator can be used when acquiring power from the traffic controller as shown in following figure. Figure 4.2. SPP radio powered from a traffic controller 14 Access Points Controller Card (APCC) Installation Guide Sensys Networks, Inc. SPP Installation Considerations Voltages The APCC uses the following voltages drawn from one of the following sources: 20VDC – 28 VDC (24 VDC nominal) – typically supplied from a nearby traffic controller cabinet or power pole 10VDC – 16 VDC (12 VDC nominal) – typically supplied from a solar panel Cabling Standard Ethernet compatible, outdoor rated, 4-pair CAT5 or better cable is required. The maximum cable length is 328 feet (100 meters) or 2,000 ft (610 meters) with isolator. The cable should be terminated with RJ45 connectors according to the TIA/EIA 568-B specification when it is installed. Collecting Data From the APCC The APCC automatically collect detection events and, depending on the network design, forward them to upstream traffic information systems and management servers via an IP network connection. An on-board Ethernet network interface facilitates this. In situations where a wired network connection is not available, a modem supporting either GSM-based or CDMA-based cellular services may be added. The following connection models are supported for IP communications: Connection via a wired network path – for example, bench configuration prior to installation, field access based on patching a technician's laptop to the APCC via an Ethernet cable, or an available wide area network connection. Connection via a wireless network path – for example, using GSM cellular networks (EDGE/GPRS data services) or CDMA cellular networks (1xRTT data services). Additionally, event data may be forwarded to a local traffic signal controller via an APCC. This interface converts event data to the signal pattern required by the traffic controller. Determining the Location of the SPP The physical location of the SPP is the primary determinant of communications quality and, as such, the network's overall usefulness and reliability. Selecting a location involves several factors (including other local RF transmissions) that may make pre-assigned locations problematic. Optimal Location Criteria Optimal locations for SPP digital radios meet all of the following criteria: are high enough to promote high quality RF communications on a sustained basis allow a line-of-sight path to (optional) isolator, wireless sensors, and repeaters Sensys Networks, Inc. Access Points Controller Card (APCC) 15 Installation Guide Chapter 4 are within recommended distances for the APCC, (optional) isolator, and wireless sensors allow the SPP to be mounted with its bulkhead connector and cellular antenna (if applicable) pointed toward the ground are within specified cable length limits do not submit the SPP to avoidable vibration, shaking, or movement are reasonably accessible to field support personnel 16 Access Points Controller Card (APCC) Installation Guide Sensys Networks, Inc. Chapter 5 APCC Installation Procedures This chapter provides the instructions for installing and cabling an APCC. Overview Installation and setup of APCC occurs at the site of the traffic controller and consists of the following activities: Determining the Card ID and Setting it via Circuit-board Dip Switches SW1 and SW2 Determining the Controller Type and Setting it via Circuit-board Dip Switch SW1 Connecting the Cables to Each Device Determining the Card ID and Setting it via Circuit-board Dip Switches SW1 and SW2 APCC and EX cards are addressed via a value known as the Card ID. A Card ID must be unique to the network and is required for communication between the APCC and the EX cards. Card ID values are expressed as: [ shelf number ] - [ slot number ]. Both shelf-number and slot-number must be determined to create a Card ID. Some traffic controllers designate the card address, while others (typically older models) do not. In the latter case, the installer assigns the Card ID ensuring that it is unique to the network. Follow the procedures in this section for each contact closure card to be installed. Sensys Networks, Inc. Access Point Controller Card (APCC) 17 Installation Guide Chapter 5 Factory Default Card ID Card IDs are implemented on Sensys Networks contact closure cards via two dip switches found on the side of the card. In this guide, the switches – named SW1 and SW2 respectively – are referred as circuit-board dip switches to differentiate them from other dip switches on the front-panel of contact closure cards. A default Card ID of “03-15” is assigned at the factory and is shown in the following figure. NOTE: On the card, switches SW1 and SW2 are not as close to one another as shown in the figure. Figure 5.1. Default card ID (all dips down) Before proceeding, ensure that switches SW1 and SW2 are set as in Figure 5.1 and, additionally, that all front-panel switches are in the right-hand position. Querying the Backplane for an Assigned Address The APCC support an operating mode (called X mode) that queries the traffic controller backplane for an address. Because it can be difficult to determine from visual inspection if the backplane dictates card addresses, the standard practice is to use X mode to see if this is the case. X mode uses the four front-panel channel LEDs to visually indicate the backplane address assigned by the controller (if any). (Refer to Appendix A: X Mode LED Displays for Slot Numbers for a figure that depicts how the channel LEDs are used.) Follow these steps to use X mode to query the controller for a card address: 1. Verify that the APCC is set to its default Card ID and that all front-panel switches are in the right-hand position. 2. Reset the APCC by pressing the master reset button (located on front-panel next to channel LEDs) or removing the unit from the cabinet and re-inserting it. 3. Observe the front-panel channel LEDs. Match the pattern of lighted LEDs with the figure in Appendix A: X Mode LED Displays for Slot Numbers. The address value that matches the LED display pattern (from Appendix A) is the slot number component of the Card ID. 18 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. APCC Installation Procedures NOTE: After the cabinet backplane is queried for an address, be sure to take the APCC card out of X-mode by setting front-panel dip switch 2 to the right, and resetting the card. Setting the Slot-Number With Circuit-board Dip Switch SW2 Circuit-board dip switch SW2 implements the slot number component of the Card ID. Set switch SW2 to match the value derived from the figure in Appendix A subject to the exception noted below. Exception In cases where the controller does not assign an address, the installer will see a front-panel channel LED display pattern indicating an address of 15 (all LEDs lighted). This address can be used for the first contact closure card installed. However, subsequent cards must be given a different address – arbitrarily assigned by the installer. Any value between 0 and 15 may be used; remember that Card IDs must be unique for the network. Refer to Appendix C: Circuit-board Dip Switch SW2 Settings for a figure that illustrates how to set switch SW2 to values between 0 and 15. Setting the Shelf-Number With Circuit-board Dip Switch SW1 Circuit-board dip switch SW1 implements the shelf number component of the Card ID. Shelf numbers are assigned by the installer after visually inspecting the cabinet. The convention is to consider the top-most shelf in the card rack as shelf zero and to increment the shelf number by one for each shelf below the top-most shelf. For example, the bottom shelf in a cabinet of four shelves would be considered shelf three. Set circuit-board dip switch SW1 to the shelf number using the two left-most switches. Refer to Appendix B: Circuit-board Dip Switch SW1 Settings for a figure that illustrates how to set switch SW1 to values between 0 and 3. Determining the Controller Type and Setting it via Circuitboard Dip Switch SW1 At the factory, contact closure cards are set for use with Type 170, Type 2070 (without status relays), or NEMA TS1 traffic controllers. This setting is made with switch three of circuit-board dip switch SW1. Verify the controller type and set dip three of circuit-board dip switch SW1 as needed. Use the figure in Appendix B: Circuit-board Dip Switch SW1 Settings as a guide for setting switch three of SW1 to the proper value. Sensys Networks, Inc.

Outdoor rated Cat5e Ethernet cable – to build the SPP cable; length is determined by the distance between the SPP mounting location and the source of power (typically a controller cabinet, solar panel or other available source) Access Point Controller Card (APCC) 23 Installation Guide Chapter 6 2 straight-through Cat5 Ethernet cables – each approximately three feet in length; used in installations where the SPP is connected to a contact closure card in a controller cabinet. Additional straight-through Cat5 Ethernet cables – optional; each approximately one foot in length; these cables are used to daisy chain multiple contact closure cards. Required only in the case of multiple CC/EX cards. Lift truck – to install the SPP 16 – 30 feet above the road surface Screwdriver – combination flat and Phillips head ends Universal mounting kit – double-socket arm holds the SPP. (Kit can be purchased from Sensys Networks.) Clamp band kit – for attaching double-socket arm to mounting pole. (Kit supplied by Sensys Networks.) Pliers – used to work the clamp band Wire cutters – used to cut the clamp band Step-by-Step Procedures The square surface mounting ball plate can be installed on any available vertical surface sufficient to support the SPP including poles, walls or beams. This section provides procedures for pole installation; considerations for wall or beam mounting follow this section. Installing the Mounting Plate on Poles When attaching the square surface mounting ball plate to a pole, the clamp band is used to secure the ball plate to the pole. (Refer to Appendix A for more information about working with the clamp band.) Follow these steps to perform the installation: 1. Use the measuring tape to determine the circumference of the pole that will hold the ball plate. 2. Subtract four inches from the measured circumference and cut the band to that length. Cut the band through the center of the nearest round hole. 3. Feed the clamp band through the square ball plate using the custom clamp holes (refer to the following figures) until the square ball plate is at the center of the band. Attach the fastener to one end of the band by diagonally inserting the end. 24 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. SPP Installation Procedures Figure 6.2. Clamp band threading through surface mounting ball plate 4. Use the cloth to clean the area of the pole that will meet the ball plate. Remove the double stick tape cover from the back of the plate, wrap the clamp band around the pole, and attach the second (non-engaged) end of the fastener. Tighten the clamp to secure it. 5. Attach the double socket arm to the square ball plate. 6. Attach the SPP ball plate to the other end of the double socket arm. Figure 6.3. Double socket arm installation 7. Point the front of the SPP toward the wireless sensors and tighten the double socket arm to secure the SPP digital radio's position. Installing the Mounting Plate on Walls When attaching the square surface-mounting ball plate to a flat surface, the clamp band is not used.

Access Point Controller Card (APCC) 33 Installation Guide Chapter 6 34 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Chapter 7 Configuration This chapter explains how to configure channels and other operating elements of contact closure cards in the APCC and EX cards. NOTE: Prior to configuring channels, ensure that each contact closure card has been given a unique Card ID. Refer to the Identifying the SPP and Sensors section in the Installation Considerations chapter for more information. Overview Each channel of an APCC or EX card is configured separately. Configuring a channel consists of the following activities: Enabling (or disabling) the channel Specifying the channel mode Setting a presence mode modifier (optional) Specifying the type of communication used to disclose channel status Additionally, after channel configuration is completed, TrafficDOT is used to define the sensor-to-channel mappings stored on the APCC. After all configuration work is complete, including definition of sensor-to-channel mapping entries for all channels, Sensys Networks recommends verifying the operation of each channel using the front-panel channel LEDs. Sensys Networks, Inc. Access Point Controller Card (APCC) 35 Installation Guide Chapter 7 Configuration Methods Configuration occurs through two mutually exclusive choices: (i) the card's frontpanel interface or (ii) with TrafficDOT, the system management application from Sensys Networks. This chapter includes the following sections: Configuring Channels With the Front-Panel Interface Starting TrafficDOT and Connecting to an APCC Configuring Channels with TrafficDOT Defining Sensor-to-Channel Mappings Exiting TrafficDOT Configuring Channels With the Front-Panel Interface After completing the configuration of all channels, continue setting up the APCC by starting the TrafficDOT software utility and defining the sensor-to-channel mappings. NOTE: If the APCC is configured with TrafficDOT, this section can be ignored. General Procedure The general procedure for configuring channels via the front-panel is provided below. Examples of specific configuration activities are included in the following sections. The steps are as follows: 1. Select a channel. 2. Move dip switches (as required) to represent the desired settings. 3. Press the MASTER RESET button on the card front-panel and hold it down for a minimum of five seconds. 36 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Configuration Figure 7.1. Configuration via the front-panel interface Saving the Configuration After the MASTER RESET button is pressed, the LINK LED flashes. When the flashing stops, the settings have been stored in flash memory. The sections below give examples of setting specific configurations via the frontpanel interface. The procedures may be performed in any order or combination. Enabling / Disabling a Channel APCC and EX cards ship with channels one and two enabled. Sensys Networks recommends explicitly disabling all unused channels. Follow these steps to enable or disable a channel. 1. Position front-panel dip switch 8 to the left to enable (to the right to disable) the channel. Figure 7.2. Enabling (disabling) a channel with front-panel dip switch 8 2. Press the Enter button for five seconds to save the configuration to flash memory or continue with other configuration activities described in this section. Sensys Networks, Inc. Access Point Controller Card (APCC) 37 Installation Guide Chapter 7 Specifying the Channel Mode Contact closure cards operate in either pulse or presence mode. (Refer to the Sensys Networks VDS240 Wireless Vehicle Detection System Reference Guide for information about the operating modes.) Follow these steps to specify the operating mode of the channel. 1. Position front-panel dip switch 7 to the left to select presence mode or to the right to select pulse mode. Figure 7.3. Selecting the channel operating mode with front-panel switch 7 2. Press the Enter button for five seconds to save the configuration to flash memory or continue with other configuration activities described in this section. Setting a Presence Mode Modifier (Optional) Channels operating in presence mode may use a modifier to delay the onset of or extend the duration of a contact closure. The modifier type and scope is specified using front-panel dip switches five and six together. (Refer to the Sensys Networks VDS240 Wireless Vehicle Detection System Reference Guide for more information.) Using Delay and Extension When Delay or Extension are specified, the rotary dial is used to articulate the numeric value associated with the parameter. When Delay is specified, the value set on the rotary dial is taken directly. This allows the 16-step rotary switch to represent values from 0 to 15. When Delay+16 is specified, the value set on the rotary dial is incremented by 16. This allows the 16-step rotary switch to represent values from 16 to 31. When Extension (EXTN / 2) is specified, the value set on the rotary dial is divided by 2. This allows the 16-step rotary switch to represent values from 0 to 7.5 in ½ step increments. Specify a contact closure delay or extension for channels operating in presence mode by following these steps: 1. Position front-panel dip switches 5 and 6 and the front-panel rotary switch to reflect the desired modifier and scope value. Use the figure below as a guide. 38 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Configuration Figure 7.4. Setting a delay or extension with front-panel dip switches 5 and 6 (rotary switch not shown) NOTE: This step is optional; set both dips to right-hand position to disable the feature. Additionally, front-panel switches 5 and 6 are ignored for channels operating in pulse mode. 2. Press the Enter button for five seconds to save the configuration to flash memory or continue with other configuration activities described in this section. Specifying the Type of Communication Used by the Channel Status Monitor Contact closure cards indicate the status of each channel via the front-panel LEDs. The state of an LED corresponds directly to the channel state. When the LED is on, the channel relay is closed indicating a call. When the LED is not on, the channel relay is open. Additionally, a contact closure card can be set such that closed channel relays activate an audible tone (buzzer) as well as the front-panel LED for the channel. The audible channel status tone is set via front-panel dip switch one as follows: 1. Position front-panel dip switch 1 to enable or disable the audible channel status monitor. Use the figure below as a guide. Sensys Networks, Inc. Access Point Controller Card (APCC) 39 Installation Guide Chapter 7 Figure 7.5. Setting the channel monitor buzzer with front-panel dip switch 1 2. Press the Enter button for five seconds to save the configuration to flash memory or continue with other configuration activities described in this section. Starting TrafficDOT and Connecting to an APCC TrafficDOT is a configuration manager and monitoring tool for an access point and all its associated devices (sensors, repeaters, and contact closure cards). TrafficDOT provides a graphical user interface (GUI) to the network's devices, settings, and operations. The GUI simplifies both configuration and management of installations. TrafficDOT requires an IP network connection to the APCC. When configuring contact closure cards, the connection is made by cabling a laptop to an APCC or EX card. (Refer to the section Cabling Summary in Chapter 5 for additional information.) NOTE: Refer to the TrafficDOT Set Up and Operating Guide for a more information on using TrafficDOT with the Sensys Networks Wireless Vehicle Detection System. Connect to the APCC with TrafficDOT by following these steps: 1. On a Windows laptop or PC, start TrafficDOT by clicking its icon. TrafficDOT's Main window opens with the Connect window open in front of it. 40 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc. Configuration Figure 7.6.

Configuration Figure 7.9. Controller Card Channels tab Configuring Channel State Contact closure card channels are independent of one another and are individually configured. Each channel occupies one of the following states: Enabled – the channel is operational; Sensor event data collected by the access point is transmitted to the contact closure card. Disabled – the channel is not operational. (When a channel is disabled, its contact closure relay and status relay are continuously open.) The factory default configuration enable channels one and two. Ensure that any unused or unavailable channels are disabled. Configuring Channel Mode Enabled channels operate in one of the following modes: Pulse – the contact closure relay pulses for 0.125 seconds each time the leading edge of a vehicle is detected. Presence – the contact closure relay remains closed while a vehicle is detected. The factory default setting is pulse mode. Sensys Networks, Inc. Access Point Controller Card (APCC) 43 Installation Guide Chapter 7 Configuring Presence Mode Modifier The behavior of a channel operating in presence mode may adjusted by applying one of the following modifiers: Delay – defers the onset of the contact closure by a specified duration. If a vehicle moves off of the sensor before the specified delay expires, the contact does not close. Delay is expressed in seconds from zero to 31. Extension – increases the duration of the contact closure by a specified increment. Extension is expressed in half-seconds from zero t0 7.5. The modifiers do not apply to channels operating in pulse mode. Configuring Channel Holdover Duration The Channel Holderover parameter allows an extension to the channel holdover duration when it is activated by the events from a particular sensor. Values from 0.0 to 0.75 are available for selection. Defining Sensor-to-Channel Mappings To map sensors to an APCC or EX card, perform the following steps: 1. Select a sensor from the image map. 2. Open the Card Addresses window by clicking the Card Addresses tab. The Extension entry extends the duration of an APCC or EX card on a per-sensor basis. The Delay entry delays the duration of an APCC or EX card on a per-sensor basis; these entries are optional. The shelf number-slot number is a card address associated with an APCC or EX card, and channel is between 1 and 4. 44 Access Point Controller Card (APCC) Installation Guide Sensys Networks, Inc.
