1 SmartSightTM 1000 User Manual / Rev 0.33b CHAPTER 1 Overview 1.1 Product The SmartSight™ 1000 is a professional video transmission product designed for the CCTV (Closed Circuit Television) market. It offers a secure (encrypted using a Wired Equivalent Privacy algorithm) signal 100 times more robust to interference than conventional AM/FM analog systems. The system consists of a video transmitter (S1000-TX) and a video receiver (S1000-RX). 1.2 Equipment Your S1000 shipment should contain the following items: • 2 - S1000 or S1000-24VAC modules (S1000-TX & S1000-RX) • 2 - wall mounting bracket set • 2 cable assemblies (P/N S1000-CA-9P) • User’s manual. The shipment may also contain the following options: • 1 or 2 16 dBi gain antennas (S1000-PA) • 1 or 2 15 VDC external power supply (S1000-PS) • 1 or 2 Pole mount bracket sets (S1000-PM) • 1 or 2 Junction Box with 24 VAC input (S1000-JB). • 1 or 2 optional alarm/audio cable assemblies (P/N S1000-CA-8P) ___________________________________________________________________ If you have not ordered a power supply option (S1000-PS or S1000-JB) you will need to supply a 12-15 VDC power supply to each module (or 24 VAC if you have ordered the S1000-24VAC system). We recommend using a power supply with a capacity of 8 watts or more. ___________________________________________________________________ ___________________________________________________________________ Check the material against the packing list to make sure you have received everything. If something is missing or if you discover shipping damage, please contact your dealer or distributor. ___________________________________________________________________
2 CHAPTER 2 S1000 system setup guide The S1000 is to be professionally installed. The guidelines in the following subsections will assist the installer in cabling and installing the Microflex. 2.1 External module description The S1000 (Transmitter) is labeled “Tx” and the S1000 (Receiver) is labeled “Rx”. St at usTM Figure 1 S1000 – External view. The S1000 electronics are enclosed in a weather-tight cast aluminum module. All cable entries are mounted on the underside of the module to maintain its weather-tight properties. The front panel of the S1000 integrates one bi-color visual indicator that indicates the module operational state. Main connector (Video, Power and Serial Port) Auxiliary connector (Alarm I/O and Audio) Status indicator
3 SmartSightTM 1000 User Manual / Rev 0.33b 2.2 Applications The current software version of the S1000 supports operation in point-to-point. Future software upgrades will support transmission of video to multiple receivers as well as retransmission of signal in none-line-of-sight application. The S1000 supports 3 non-overlapping channels (channels 1, 6 and 11) or operation of 3 simultaneous links within the same location. It is also possible to support up to 6 links simultaneously with each of the six receivers installed at the same location. However, this requires some site planning (see CHAPTER 4). In most case, you will need to program a unique SSID (security ID) for each radio system (see 4.2.4 to learn how to configure each module using a computer). As an example, for 3 S1000 systems, 3 individual SSID are required. The table below shows the configuration applied to each module: Module Configured Channel Configured SSID S1000-TX 1 1 SYSTEMA S1000-RX 1 1 SYSTEMA S1000-TX 2 6 SYSTEMB S1000-RX 2 6 SYSTEMB S1000-TX 3 11 SYSTEMC S1000-RX 3 11 SYSTEMC
4 CHAPTER 3 S1000 System Configuration and Installation 3.1 S1000 system configuration Your S1000 system is configured to operate right out of the box with the most popular dome data port configurations (4800 baud, 8 data bits, no parity, 1 stop bit). For added security, we recommend you change the SSID to your own secret SSID and activate the WEP encryption and change the WEP key to your secret WEP key before installing the system. STEP 1 Initial Configuration • Unpack the modules and set them side by side on a desk or table. • Unpack the 2 cable assemblies (P/N S1000-CA-9P) and connect them to the module (you must feel a positive click for the cable assembly connector to be properly installed on the module) • Connect the S1000-TX cable assembly DB-9 to a computer (if the DB9 has been removed, refer to the table below to connect conductors properly) and power the module (the STATUS LED should turn steady green and then flashing green under normal operation; see the next section to understand how this LED behaves under different operation conditions) S1000-CA-9P TO PC CONNECTION S1000 Cable Assembly Serial Port Description (DCE port) Computer (DTE) SIGNAL NAME WIRE PAIR WIRE COLOR SIGNAL NAME CTS GREEN Not used RxD GREEN/ BLACK BLACK RX TxD YELLOW TX RTS YELLOW/ BLACK BLACK Not used Signal GND BROWN Signal GND Signal GND BROWN/ BLACK BLACK Signal GND NOTE: Power the unit via the cable assembly RED & BLACK conductor pair. The RED conductor is for 12 VDC input (or 24VAC if this option was purchased) and the BLACK conductor is for the power GROUND (or 24 VAC return if this option was selected).
5 SmartSightTM 1000 User Manual / Rev 0.33b • Configure the S1000-TX SSID, WEP encryption key (if desired), radio channel and serial port parameters (if required) via the computer (see 4.2.4 for configuration procedure) • Connect the S1000-RX cable assembly DB-9 to the computer and power the module (the STATUS LED should turn steady green under normal operation; see the next section to understand how this LED behaves under different operation conditions). • Configure the S1000-RX parameters to the SAME parameters configured on the S1000-TX • You have completed the S1000 initial configuration. The system can now be installed outdoors. ___________________________________________________________________ The S1000 integrates a single serial port. This port is used for both system configuration and data communications (PTZ, access control or other). The serial port on the S1000 automatically detects if it is connected to a computer (RS-232 serial port) or an RS-422 serial device. The user does not have to configure the serial port for RS-232 or RS-422/485 operation or for configuration or data communications. __________________________________________________________________ 3.2 Understanding the status led The STATUS LED is a bi-color (GREEN-RED) LED which provides detailed information on the system depending on whether the system is powering up, in operation or the software is being updated. Power-up sequence: • Flashing Red (module is powering up) • Steady Green (Application is started). ___________________________________________________________________ In very cold weather, the powering up sequence may take several minutes (up to 15 minutes at –30°C). This is because the module must reach a certain internal temperature before powering up all the electronics. ___________________________________________________________________ ___________________________________________________________________ The following power-up conditions are abnormal: 1) LED not lit: Check the power supply and cabling, if power is available and the LED stays off, call SmartSight technical support to obtain an RMA authorization. 2) Steady RED LED: There is an internal module error that prevents the unit from
6 starting normally. Power down and power back-up the module once. If the condition persists proceed to a firmware upload (see CHAPTER 6) and if this fails or the condition persists after the new upload, call SmartSight technical support to obtain an RMA authorization. ____________________________________________________________________________ Tx After Power-up:  Flashing Green (steady rate) if not communicating with another module.  Flashing Green (various rate) if system communicating.  Flashing Green with intermittent Red flash if the radio link is not very good and there are video frames lost. Rx After Power-up:  Steady Green (if not communicating with another module).  Flashing Green (various rate) if system communicating.  Flashing Green with intermittent Red flash if the radio link is not very good and there are video frames lost. ___________________________________________________________________ When communication is established between the transmitter and receiver, the GREEN LED flashing rate is an indication of the number of frames transmitted every second. If the link is very good the rate will be high. Under poor link conditions, the system will retransmit video frames constantly and the frame rate will decrease as a result. If there are too many retransmission of video frames some video frames may be lost and the picture quality may degrade momentarily (a flashing RED LED indicates this state). ___________________________________________________________________ 3.3 S1000 system installation STEP 2 Installing the S1000 system in it’s final location • Once your system is successfully configured it is ready to be installed • Carefully review the site planning information presented in CHAPTER 4 to optimize your system radio performance. • If installing the S1000-TX on a light pole or mast, we suggest you use the S1000-PM pole mount brackets and stainless steel clamps (for wall mounting use the module side brackets). • ALWAYS mount the S1000 modules with the industrial bayonet type black connector pointing downwards. • Connect the S1000-CA-9P cable assembly to the S1000 module and route the cable to the dome or camera (all connections for the S1000-24VAC model can be made inside a dome or motorized camera if 24 VAC is being used for these devices). If the S1000-JB interconnection box is being used, route all conductors to the S1000-JB first and then route all conductors from the S1000-JB to the dome or camera).
7 SmartSightTM 1000 User Manual / Rev 0.33b • Cut-off the DB-9 connector from the cable assembly in order to connect the serial port to the dome or camera PTZ port terminals. Refer to one of the following tables (whether using RS-422/485 or RS-232) to connect the serial port to the target serial device: S1000-CA-9P TO CUSTOMER EQUIPMENT CONNECTION (RS-422/485 configuration) S1000 Cable Assembly Serial Port Description (DCE port) Customer Equipment (DTE) SIGNAL NAME WIRE PAIR WIRE COLOR SIGNAL NAME RxD+ GREEN RX+ RxD- GREEN/ BLACK BLACK RX- TxD+ YELLOW TX+ TxD- YELLOW/ BLACK BLACK TX- Signal GND BROWN Signal GND Signal GND BROWN/ BLACK BLACK Signal GND S1000-CA-9P TO CUSTOMER EQUIPMENT CONNECTION (RS-232 configuration) S1000 Cable Assembly Serial Port Description (DCE port) Customer Equipment (DTE) SIGNAL NAME WIRE PAIR WIRE COLOR SIGNAL NAME CTS GREEN CTS RxD GREEN/ BLACK BLACK RX TxD YELLOW TX RTS YELLOW/ BLACK BLACK RTS Signal GND BROWN Signal GND Signal GND BROWN/ BLACK BLACK Signal GND • Carefully align the S1000-TX and RX modules so that both antennas are in good line-of-sight alignment. • Upon power up, verify that the STATUS LED turns STEADY or FLASHING GREEN.
8 ____________________________________________________________________________ The S1000 must always be installed with the black bayonet connector pointing downwards. Failure to install the module properly can cause moisture to penetrate the module and may void the warranty. ____________________________________________________________________________ Figure 2 Example of a pole mount installation STEP 3 Installing the optional S1000-PA high gain antenna • The S1000-PA is supplied with an adjustable pole mount bracket. It is designed for mounting on a mast or pole of 2-3 inch diameter. • The S1000-PA includes a one (1) meter pigtail cable to connect to the S1000 module. We recommend the antenna be mounted above the S1000 module. Screw the pigtail connector (called an SMA connector) to the S1000 antenna port and tighten with a small adjustable wrench (do not over-tight to avoid damage to the connector) • The antenna cable and connectors are weather-tight, however vibration caused by the wind will over time loosen the connectors and reduce the efficiency of the gaskets. The S1000-PA antenna is shipped with waterproofing potty and electrical tape. We recommend you apply the potty around the two junctions between connectors at both the antenna and module end and wrap 2-3 layers of electrical tape around the potty. • Carefully align the S1000-PA antenna with the other antenna so that both antennas are in perfect line-of-sight.
9 SmartSightTM 1000 User Manual / Rev 0.33b CHAPTER 4 Proper RF and Network Planning The S1000 offers a robust and highly reliable spread spectrum wireless link, which can operate up to 4 miles line-of-sight with appropriate installation. For best operation, the system(s) must be properly planned (see section 4.1) and the antennas must be installed in such a way as to obtain a line-of-sight link (see section 4.2) 4.1 Network Planning 4.1.1 Co-locating up to 3 systems Three (3) S1000 can be co-located without special consideration for antenna placement and antenna type. The following steps must be taken to operate three (3) systems in the same area (failure to do so will cause interference between systems) • Assign a unique SSID for each system (use any 4-32 characters for this ID). The default SSID of each S1000 shipped is ‘SMARTSIGHT’. • Assign channel 1 to one system, channel 6 to the second system and channel 11 to the last system. 4.1.2 Co-locating up to 6 systems (360 degree coverage) If you are installing up to 6 S1000 receivers on the same mast and they are pointing in different directions (at least covering 270 degrees), here is the procedure to use: • Install the optional antenna S1000-PA on each S1000-RX (the integrated antenna does not offer sufficient isolation to be used at the S1000-RX end in this application). • Assign a unique SSID for each system (use any 4-32 characters for this ID). The default SSID of each S1000 shipped is ‘SMARTSIGHT’. • Assign each system with a separate channel as shown in the table below:
10 Module Configured Channel Configured SSID S1000-TX 1 1 SYSTEMA S1000-RX 1 1 SYSTEMA S1000-TX 2 3 SYSTEMB S1000-RX 2 3 SYSTEMB S1000-TX 3 5 SYSTEMC S1000-RX 3 5 SYSTEMC S1000-TX 4 7 SYSTEMD S1000-RX 4 7 SYSTEMD S1000-TX 5 9 SYSTEME S1000-RX 5 9 SYSTEME S1000-TX 6 11 SYSTEMF S1000-RX 6 11 SYSTEMF • Install the systems with the co-located channels (as an example channels 1 & 3, channels 5 & 7 or channels 9 & 11) back to back or as close to back to back as possible (as illustrated in Figure 3 below): Figure 3 Cross-section view of S1000-RX antennas around mast with proper channel allocation System A System BSystem C System D System ESystem F
11 SmartSightTM 1000 User Manual / Rev 0.33b 4.1.3 Co-locating up to 6 systems (less than 180 degree coverage) If you are installing up to 6 S1000 receivers on the same side of a building or on the same mast and they are pointing within the same direction (within 180 degrees direction of each other), here is the procedure to use: • Assign a unique SSID for each system (use any 4-32 characters for this ID). The default SSID of each S1000 shipped is ‘SMARTSIGHT’. • Assign two pairs of S1000-TX and RX modules on the same channel as shown in the table below: Module Configured Channel Configured SSID S1000-TX 1 1 SYSTEMA S1000-RX 1 1 SYSTEMA S1000-TX 2 1 SYSTEMB S1000-RX 2 1 SYSTEMB S1000-TX 3 6 SYSTEMC S1000-RX 3 6 SYSTEMC S1000-TX 4 6 SYSTEMD S1000-RX 4 6 SYSTEMD S1000-TX 5 11 SYSTEME S1000-RX 5 11 SYSTEME S1000-TX 6 11 SYSTEMF S1000-RX 6 11 SYSTEMF • Install the systems that share the same channels as close together as possible (as illustrated in Figure 4 below). Each two systems will now share the radio bandwidth available per channel.
12 Figure 4 Example of co-located systems with each 2 systems sharing one channel 4.1.4 Co-locating systems on different sides of a building If you are installing S1000 systems on different sides of a large building or building complex, you may be able to install more than 3 systems as long as two (2) S1000 systems that use a set of co-located frequencies (as an example channels 1 & 3) do not offer a line-of-sight view to each other. Here is the procedure to use: • Assign a unique SSID for each system (use any 4-32 characters for this ID). The default SSID of each S1000 shipped is ‘SMARTSIGHT’. • Assign each system with a separate channel as shown in the table presented in section 4.1.2 above. • Install the systems with the co-located channels (as an example channels 1 & 3, channels 5 & 7 or channels 9 & 11) in areas that do not offer a line-of-sight view to each other (for example on opposite side of the building).

13 SmartSightTM 1000 User Manual / Rev 0.33b 4.2 RF Planning Successful operation of a S1000 network lies on the proper installation of the wireless antennas. Such installation requires: 1. Evaluation of the location 2. Evaluation of antenna requirements This section presents a step-by-step approach to completing the phases outlined above. 4.2.1 Evaluation of the location Unless it is a very short link distance (less 500 feet) the path between the two antennas must be free of obstacles that could disturb propagation. Such path is called a line-of-sight path. If there are obstacles, radio waves will be in part absorbed and in part diffracted by the obstacles (multi-path fading). Even if operating in such circumstances, links could be established. However, results are highly unpredictable. The first requirement of a successful link is therefore a clear line-of-sight path. There is a second requirement related to the beam-width of a radio signal. The beam-width of a radio signal transmitted between two antennas is an elliptical area immediately surrounding the visual path (see Figure 5). It varies in thickness depending on the length of the signal path. The region outlined by this beam-width is known as the first Fresnel zone. The Fresnel zone is always thicker at the mid-point between the two antennas. Therefore a path that appears to be a perfect line-of-sight path between the base and a remote station may not be adequate for a radio signal. In practice, it has been determined that a radio path can be considered a line-of-sight path if it has a clear opening through 60% of the first Fresnel zone (0.6 F1). The table below presents the value of 0.6 F1 for various signal path distances. A common problem encountered in the field and related to the 0.6F1 clearance rule is a building obstruction. The proposed visual path may just barely clear a building but the “radio line-of-sight” won’t. In such case, the signal will be partially absorbed and diffracted. Increasing the height of the two antennas or the gain of the antennas, are the only alternatives to improve the link quality. DISTANCE (mile) 0.6F1@ 2.45 GHz (feet) 1 15 4 25 7 40 15 75

A link established in the fall or winter season may be adversely affected in the spring and summertime, if it is established below tree level. ___________________________________________________________________ 4.2.2 Evaluation of antenna requirements SmartSight offers two type of antennas to meet various distance requirements of clients, the integrated 8.5 dBi patch antenna or an external 16 dBi gain patch antenna (option S1000-PA). These can be combined together to offer the following combinations and associated system range: Range S1000-TX Antenna Gain S1000-RX Antenna Gain 4 miles 8.5 dBi 8.5 dBi 7 miles 8.5 dBi 16 dBi 15 miles 16 dBi 16 dBi Note: The above ranges are specific to a S1000 system configured at 1Mbps. The range is reduced by 30% at 2 Mbps data rate. 4.2.3 Coping with Interference In most countries, the 2.4 GHz license free band is not regulated by a government agency and this absence of frequency coordination can result in interference
15 SmartSightTM 1000 User Manual / Rev 0.33b between various systems. Fortunately, there are existing tools that can be used to avert interference: (1) RF channel selection (2) Antenna selection (1) RF channel selection The S1000 offers eleven (11) channels to choose from. If a link with a good line-of-sight is subject to excessive video delay and very low frame rate (or possibly break down of video images), it could be due to interference. In this case it is recommended to change channel until a clean channel is found. (2) Antenna Selection Replacement of the integrated antenna by the S1000-PA 16 dBi gain antenna can significantly lower interference from other radio systems. If a link with a good line-of-sight is subject to excessive video delay and very low frame rate (or possibly break down of video images), it could be due to interference. If switching channels does not correct the problem or if all channels must be used to co-locate several systems, it is recommended to replace the integrated antenna with the S1000-PA to resolve the interference problem. 4.2.4 RF Exposure Considerations In order to comply with the RF exposure requirements of CFR47 1.1310, the S1000 must be installed in such a way as to allow a minimum separation distance of 20 cm (4 in.) between antennas and persons nearby.
16 CHAPTER 5 Using the Command Line Interface to program the S1000 This chapter guides you through a step by step procedure to program your S1000 modules. Programming the S1000 does not require the installation of any software on your computer. All you will need is a terminal emulation program such as Hyper Terminal supplied with all Windows or Macintosh operating systems. Your computer must also integrate a serial COM port for connection to the S1000 module. 5.1 Reset to factory default (NOTE: Reset functionality will not be available until release 1.0 of the firmware). If at any time during the system configuration the system becomes unstable or stops responding (possibly due to the entering of a wrong value via the CLI) it is possible to perform a hardware reset. This hardware reset will cause a reset to factory configured parameters. The hardware reset is invoked by shorting together the serial port's CTS and TxD pins during the power-up sequence (The S1000-CA-9P cable assembly pin-out is presented in APPENDIX 2, figure 2). To do this proceed as follows: 1. Power down the unit 2. Short TxD & CTS conductors together 3. Power up the module and wait until the normal boot up sequence is completed 4. Remove the short on the TxD & CTS pins 5. The module is ready for use with Factory Configuration settings (see Appendix 1 for a list of these settings) Following a configuration reset, the S1000-TX or RX module might need to be re-programmed for proper operation with the other module. 5.2 Hyper Terminal Hyper Terminal is the terminal program within WindowsTM that is used to configure the modules. You may use any other ASCII based terminal emulation communication programs. The graphical interface presented in the following examples is based on WindowsTM Hyper Terminal Version 1.2. Using a different version of WindowsTM Hyper Terminal may offer a different graphical interface.

Failure to do so will prevent you from successfully using the COM port to configure the S1000 system. ____________________________________________________________________________ 5.3 S1000 CLI 5.3.1 Starting the CLI Now that Hyper Terminal is started, you have to start the SmartSight 1000 CLI. On the keyboard - Press ‘Ctrl-Break’ simultaneously, wait 1 second and then press the ‘Space’ bar. The SmartSight 1000 CLI menu should appear as seen in ’Figure 9’
20 Figure 9 CLI start up screen 5.3.2 Using the CLI In the CLI menu, enter <1>, <2> or <3> at the command line to enter the Serial Port, RF Communications or Video Settings. All entries must be followed by <ENTER> to take effect. You can always return to the previous menu by entering <r>. All letters entered in the CLI must be lower case. Once all the changes have been made enter <s> at the command line to save all the changes you have made. You will need to power down and re-power up to enable the changes. Sections 5.4, 5.5 and 5.6 provide a list of all parameters that can be modified by the user and an explanation of these parameters. 5.4 Serial port setup 5.4.1 Bit rate The bit rate represents the data rate the target product (dome, keyboard, matrix, multiplexer or access card) operates at. Refer to the product manual or contact your product manufacturer if you are unsure of the data rate of the specific product you wish to interface with. 5.4.2 Parity The parity is either odd or even or there is no parity check. Most communications devices do not use parity. Refer to the product manual or contact your product manufacturer if you are unsure if parity is used in the specific product you wish to interface with.
21 SmartSightTM 1000 User Manual / Rev 0.33b 5.5 RF communications setup 5.5.1 RF channel This option is used to configure the channel (frequency) that will be used by the SmartSight™ 1000 Units (Tx / Rx). A set of 11 channels are available. Co-located systems should always be set on different channels unless two systems are set-up to share a channel (refer to CHAPTER 4 for a more in-depth explanation). It might be also necessary to change channel if interference is present on one specific channel. 5.5.2 SSID This option identifies a pair of Units (TX and RX) that belong to the same S1000 system. The SSID must be the same for both the TX and RX module. Co-located systems must always be set on different SSID. The SSID is represented by an ASCII string of 1 to 32 characters (numbers or letters). Here are examples of valid SSID: SMARTSIGHT1000 RadioCommunications2001 123456789 wirelessvideo welcome 5.5.3 Bit rate Bit rates can be set to 1 Mbps, 2 Mbps, 5.5 Mbps or 11 Mbps where Mbps stands for Mega bits per second. A high bit rate reduces the effective distance between two functional Units. We recommend you use 2 Mbps for all system installations unless the link is not reliable. If this is the case, use 1 Mbps to improve the link quality. Using 1 Mbps will however slightly reduce the video frame rate. 5.5 and 11 Mbps should never be used at this time, they are reserved for future applications. 5.5.4 WEP Key WEP (Wire Equivalent Privacy) encryption is a mechanism that provides protection from eavesdropping using another S1000 system or a computer equipped with a wireless 802.11b receiver. The WEP key is used by the system to generate a unique encryption sequence. The WEP key must be the same for the TX and RX for the system to communicate together. The WEP key is represented by an ASCII string of 5 characters. Note that the WEP key is write only. This feature is to ensure privacy of the WEP key. Here are examples of valid WEP key:
22 12345 VIDEO SECUr $$$$$ _WEP* 5.5.5 WEP Encryption activation This option enables or disables encryption. If the WEP encryption is disabled, the system will still offer some level of protection through the unique SSID entered. SSID is not a technique of encryption, a hacker with a computer and a wireless 802.11b compliant card could receive and decode the video being received if encryption is not enabled. Note however that someone purchasing a S1000 will not be able to receive video from another S1000 system if the SSID is not known. 5.6 Video Settings setup 5.6.1 Target frame rate The ‘target frame rate’ is the maximum number of frame per seconds (fps) that will be compressed and transferred between the TX and RX modules. This parameter can be set to 15 fps and 30 fps through the CLI. Some level of ‘pixalization’ will occur when setting the module for 30 fps. This is because quality will be sacrificed for frame rate. At 15 fps, the video quality will be maintained even when panning or tilting. 5.6.2 Set target bit rate The target bit rate is defined as the maximum number of bits per second generated by the video transmitter (S1000-TX). Valid bit rates are between 64Kbps and 1000Kbps. We recommend setting this parameter to 800Kbps for maximum video quality. 5.6.3 Video standard: PAL / NTSC The S1000 Receivers and Transmitters support two analog video Standards: NTSC and PAL. NTSC is the analog television display standard that is used in North America and certain other parts of the world. PAL is the analog television display standard that is used in Europe and certain other parts of the world.
23 SmartSightTM 1000 User Manual / Rev 0.33b CHAPTER 6 Upgrading the S1000 firmware This chapter provides information on using the SmartSightTM Management Interface (SMI) to upgrade your S1000 firmware. The SMI is a user friendly and easy-to-use graphical interface running on all Windows TM compatible PCs. Install the SMI program supplied with the S1000 system on your computer and then follow the steps below to use the SMI program. Firmware upgrades or patches can be found in the support section of the SmartSightTM website. 6.1 Starting the SmartSightTM Management Interface Via Windows ExplorerTM (or any other file browser), select the <SMI.EXE> file and then press enter or double-click with the mouse. A window will appear as seen in ‘Figure 10’. SMI.EXE can also be launched from MS-DOS prompt. Figure 10 SMI start up screen 6.2 Performing a Firmware Upload Steps described below should be followed carefully while doing a Firmware Upload. STEP 1. Connect the S1000-TX computer via the serial port. If the DB9 connector was removed from the S1000-CA-9P cable assembly, you will need to re-install this connector to connect with the PC (refer to APPENDIX 2 for the cable pin-out).
24 Figure 11 Screen shot before a firmware upload STEP 2. If you are not using your computer’s COM1 serial port (the default port used by the SMI program after installation), you will have to select the correct serial port number on your computer by choosing the <Options>, <Serial port setup> path from the SMI menu. A window as the one showed in ‘Figure 12’ will appear. Note: Once you have launched SMI once, the next time you start the program it will use the last COM port selected and point to the last file uploaded. ____________________________________________________________________________ If you have installed a PDA synchronization program on your computer such as Palm HOTSYNCTM and it is using the COM port (not a USB or Infrared port) , you will first need to disable this program if it is active. Failure to do so will prevent the SMI program from opening the COM port.. ____________________________________________________________________________
