Other documentation that may be applicable includes the Application Developers Guide To Programming For The ILR Library, the i-COM User Manual, the ILR-CARD Installation & Configuration Sheet, and the i-Q Tag Technical Sheet. 1.
101053 i-PORT Block Diagram 2 i-PORT Terminal Blocks — Brief Description The i-PORT terminal block lay out is depicted in figure 2. The function of each of the connectors is described below. Caution: Never connect or Figure 1 disconnect any cable or remove or install a PC Card while the i-PORT is running. Two terminals 8 – 20V AC Input power supply for i-PORT, to be used when only an AC power source is available. Range min. 8V to max.20V AC. Recommended range is 12V to 18V AC. Two terminals pos.
101053 6V BAT- Negative terminal of 6V backup battery. This terminal is connected to system ground Note: The battery voltage must be 6V. The battery should be either a Sealed Lead Acid or a Gel Cell. The recommended minimum capacity for the battery is 2.6 Ah. This is sufficient to provide back up power for short power outages lasting a few minutes. Total of 12 GND terminals Terminal pair GND System ground. RLY 1a, 1b User relay contacts enabled by software.
101053 Two terminals, plus GND ANT SEL 1, 2 Software controlled output of two antenna selector control signals for external antenna multiplexer with maximum four antenna ports. Two terminals, 12V Auxiliary power outputs, for user selected devices. Maximum combined load for the two 12 V terminals is 250mA. Two terminals, 5V Auxiliary power outputs, for user selected devices. Maximum combined load for the two 5 V terminals is 250mA.
101053 3.1 Opto Coupled Inputs (INPUT 1…4) The opto-coupled inputs are tied to 5V via the internal opto-isolator, a limiting resistor and an input status LED. Left open, no current flows and the status LED is off. If the input is tied to ground, directly through dry relay contacts, or via a resistor of up to 100 ohms, the LED will light and the ILR CARD will see the input as ‘pulled low’.

The external multiplexer requires only a single coax cable to run from the MMCX antenna connection on the ILR-CARD to the multiplexer.
101053 RF IN Takes a 3.5 inch coax pigtail (part # CAB001) to connect the ‘RF IN’ port to the ILR-Card RF connector ANT 1, 2, 3, 4 Independent antenna ports for one to four external antennas Note: The address sequencing for the antenna multiplexer is software controlled. 5 Selector Slide Switches There are two selector slide switches on the i-PORT. One slide switch is located on the topside of the LED board, and is used to switch the bar code connection between RS 232 and RS 485.
101053 6.1 The ILR-Card The ILR-CARD is the rear PC Card on the left side. It has two I/O connectors on the exposed end, the MMCX Antenna connector, and a 15-pin programming connector. The programming connector is used by IDENTEC to configure the ILR-CARD. There are also three LEDs on the exposed end of the ILR-CARD to indicate transmit, receive and RF carrier detect. The ILR-CARD contains a Configurable Processor System Unit (CPSU) with internal non-volatile memory.
101053 interface type, either PCMCIA or serial. Do not use an ILR-CARD with a PCMCIA interface in the i-PORT. 6.2 The i-Flash Memory Card This card is a linear Flash memory device with special non-volatile memory. The standard card supplied with the i-PORT is 4MB, but optional upgrades are available for 8MB and 16MB of memory. The iFlash Card contains compressed binary image files used by the operating system running on the Computer Board.
101053 6.4.2 Modem PC Card (optional) For dial-up networking a modem card can be inserted in the User Interface PC Card slot on the i-PORT. This card would be used instead of the Ethernet Card 6.4.3 RF Modem Card (optional) For wireless networking a RF modem can be used with the i-PORT. An IEEE 802.11 (Frequency Hopping?) card is recommended. If using an RF modem it is necessary to use an external antenna because of the iPORT metal enclosure.
101053 i-PORT Annunciator LED Board Figure 3 The left side single row of LEDs in figure 3are described below. INPUT POWER Indicates the presence of external supply power for the i-PORT. EXT. BATTERY If the external power supply fails, and the 6V backup battery takes over this LED will be lit. Only one of the power source indicator LEDs, the INPUT POWER or the EXT. BATTERY, will be lit at anyone time. 30V Internal 30V supply present. 12V Internal 12V supply present. 5V Internal 5V supply present. 3.
101053 Note: The internal voltage LEDs will all be illuminated when input power is applied. There are no LEDs for the auxiliary power outputs. EXT. BATTERY Indicates the 6V backup battery is being charged. CHARGING RSSI Receive Signal Strength Indicator (currently not used). TRIGGER Displays activity on the BARCODE TRIGGER input. LCD HEATER Displays heater element on (when equipped). The right side Annunciator LEDs are organized and labeled in pairs.
101053 INPUT 3 Lights when terminal INPUT 3 is active (shorted to ground). INPUT 4 Lights when terminal INPUT 4 is active (shorted to ground). OUTPUT 1 Lights when user relay contacts RLY 1a, 1b are closed. OUTPUT 2 Lights when user relay contacts RLY 2a, 2b are closed. OUTPUT 3 Lights when user relay contacts RLY 3a, 3b are closed. OUTPUT 4 Lights when user relay contacts RLY 4a, 4b are closed. ANT 1, 2, 3, 4 Displays selector status of antenna multiplexer.
101053 For an AC power supply the output voltage must be between 8V and 20V AC. The recommended power range is 12V to 18V AC. Output power rating should be no less than 14VA AC. The suitability of the power supply output can also be determined with an output current rating of 1A minimum at 12V, or a current rating of 1.5A minimum below 12V. Example: The output current of the transformer must be capable of no less than 1000mA for a 12V AC/DC linear supply. 9.1.
Environment Range Physical 101053Dimensions Weight Operational Temperature Humidity Storage Temperature Humidity 11.75" x 7.75" x 3.2" (30 x 20 x 8 cm) 7.5 lbs (3.4 kg) 32° F to 158° F (0° C to 70° C) 90% non-condensing -40° F to 185° F (-40° C to 85° C) 90% non-condensing 11.1 Physical Installation The rugged i-PORT enamel steel enclosure is intended to be wallmounted with four adequately sized screws.
101053 Note: The Ethernet CAT 5 cable will have to be terminated with an RJ45 connector after feeding it through one of the five compression clamps. Note: The Ethernet cable needs to run through the Ferrite Box Snap to suppress RF noise from the Ethernet Card. The cable should be wrapped around the Ferrite Box so the cable passes through the box twice. The installed Ferrite box should be attached to the Ethernet cable inside the i-PORT, and placed in the bottom left corner of the enclosure. 11.
101053 Every time the i-PORT is started the RestoreReg file will be loaded. This program reads applicable keys from the i-PORT registry and compares the existing default key values with the values stored in the “ipsettings” file. Any changes made in the “ipsettings” file will be used by the system. These changes are stored in the i-PORT RAM and are updated from the “ipsettings” file anytime the i-PORT is rebooted. If a new ATA Flash Storage Card is used in the i-PORT the “ipsettings” file must be updated.
101053 Figure 5 The i-PORT can connect up to four antennas using either the internal multiplexer or an external multiplexer. The cable to connect the ILRCARD to the internal multiplexer is supplied with the i-PORT. To connect an external multiplexer the coax cable to the ILR-CARD can use a SMA connector with the supplied antenna pigtail as a connector converter, or the coax will require an MMCX male end to connect directly to the ILR-CARD.
101053 13 i-Q Tags IDENTEC i-Q tags are available in a number of configurations to match the tag with the application. Tags of different types can be mixed in a single system and can be interrogated simultaneously by an i-PORT. Tags are available as read only, read/write with 8 KB of memory, and a read/write tag with and optional temperature monitor. Tag memory is expandable to 32KB.
101053 14 Software This chapter provides basic information on how to control the operation of the i-PORT. For more detailed information please see the Application Developers Guide To Programming For The ILR Library. ILR technology requires an application program to provide end-user functions, this level of software is provided by the System Integrator.
101053 15 ILR Explorer Demonstration/Testing Software ILR Explorer runs on a host Computer to demonstrate and test the capabilities of an i-PORT. The system requirements are a 486 or higher CPU, running Windows 95 or newer, with a minimum of 120MB of hard drive space. The i-PORT is equipped with an Ethernet card for connection to a LAN, or it can be connected directly to an Ethernet equipped computer by using a mirrored Cat. 5 cable. The Ethernet card included with the iPORT is a 10BaseT connection.
