Before reading the instructions below, it is suggested that the following equipment will be required:• OEM400 product• Suitable external antenna, it is recommended that the ACC285 antenna be used• Regulated, bench power supply• PC running Windows 95/98/00™ with a spare communications port• Standard 9-pin D-type male to female extension cable• ACC158 D-type to Molex connector (see section 4.4 for a wiring diagram)• Selection of high frequency tags• SIRIT Software Support Suite CD-ROMAll component references made in this section can be identified in the diagrams provided in section 4.32.2 Power and serial connectionsThe OEM400 product requires a single source of external power, which should be specified at +5V (± 0.2V)with less than 50mV ripple. At most, the board will draw 210mA and therefore a 250mA supply isrecommended. Power is fed to the board via a single 10-pin Molex connector (CN2), part number 53261-1090. The mating part for this connector is Molex part 51021-1000. This connector is also used for the sendand receive lines for serial communications.Table 2-1 shows the pin allocation for the Molex connector.Pin Name Description1GNDGround, 0V2OP2Open collector output 23OP1Open collector output 14IP2Input 2, TTL level5IP1Input 1, TTL level6TXDBoard transmit line (serial out), RS232 levels7ENWake-up input line, +5V on, 0V off8RXDBoard receive line (serial in), RS232 levels95V+5V DC10 NIL No connection should be made on this pinTable 2-1 : Pin allocationsIMPORTANT NOTE: There is no built-in protection for over voltage or incorrect polarity setting on thisproduct. Damage to the product under such conditions is not covered under thestandard product warranty.Serial transmit and receive lines should be connected to pins 6 and 8 respectively. The OEM400 product cancommunicate at a variety of baud rates (see section 2.4), however, port setting should be set as follows:• 8 data bits, 1 stop bit, no parity, no handshaking
© Copyright 2002, SIRIT Technologies : Manual version 2.03 Page 6 of 15First time operationOEM400 2The OEM400 product is shipped with a factory default RS232 communication interface, however, TTL levelcommunications is also possible. To communicate with the product at TTL levels, two 0603 0 ohm resistorsshould be soldered on pads R136 and R137 on the underside of the board. See section 4.3 for the locationof these pads.Note that sending RS232 level signals to an OEM400 product, when configured to receive TTL level signals,may result in damage to the board.2.3 Antenna connectionA 2-pin Leotronics connector (CN1) is provided on the board for connection of an external antenna. The partnumber for this connector is 2010s02000, with mating parts as follows:• 24-26 AWG wire, maximum insulation of 1.56mm: part 2033tbp000• 28-30 AWG wire, maximum insulation of 1.40mm: part 2033tbp00v1The OEM400 product requires an antenna tuned to resonance at 13.56MHz and should present a 50ohmload at this frequency. A return loss of (S11) of –20db or greater is preferred for reliable operation. Theloaded Q of the antenna should be in the range 10 to 25 in normal operation.Whilst performing initial test and set-up procedures it is recommended that the standard ACC285 antenna beused. This will be provided with a pre-wired Leotronics connector.Note that the OEM400 does not have an integral antenna. An external antenna must be connected tointeract with tags, however, the board will power with or without an antenna present. It is recommended thatpower be removed from the board when adding or removing an external antenna.2.4 Baud rate settingsThe OEM400 product may be configured to operate at one of four baud rates. These are selectable usingtwo solder pads located on the rear of the board. These are named SB1 and SB2.Unless specifically documented, the OEM400 is factory set to 57,600 baud.Table 2-2 shows the states of solder pads 1 and 2, used to set the baud rate.Baud rate Pad SB1 Pad SB2 Pads SB3-857,600 Open Open Not used38,400 Open Closed Not used19,200 Closed Open Not used9,600 Closed Closed Not usedTable 2-2 : Solder pad settings for baud rateConnection between pads should be made using an 0603 0 ohm resistor, however, the pads are locatedclose enough that they may be bridged with solder alone.2.5 Digital I/ODigital I/O is provided on the OEM400 product through pins 2 to 5 (see Table 2-1). Outputs are opencollector, and inputs are via a 100K pull-up resistor.For details of setting and detecting the state of the digital I/O, please refer to the SLC Protocoldocumentation.

All resistors are 0805 size and should be specified to 5% 0.1W.Output power levels are achieved by adjusting the values of the three resistors in accordance with the dataprovided in Table 2-3.Attenuation R63 Value R64 Value R65 Value0 db 100k 0R Not fitted- 1db 910R 5R6 910R- 3db 300R 18R 300R- 6db 150R 36R 150R- 9db 100R 62R 100R- 10db 100R 68R 100RTable 2-3 : Resistor settings for adjusting output powerUnless specifically documented, the OEM400 product is factory set to 0 db.2.7 Installing and loading the SLC test softwareIn order to determine the correct operation of the OEM400 product, it is recommended that the SLC testsoftware be installed. This can be installed from the Autorun™ menu on the Software Support Suite CD-ROM, or can be started manually by running the setup.exe program from the ‘\SLC_test’ directory. Follow theon-screen prompts, which will guide you through the installation of the software.Once completed, the ‘SLC test software’ icon will be available in a SIRIT folder on the Windows™ StartMenu. Clicking on this icon will load the software and automatically show the commands screen, shown inFigure 2-1.Figure2-1 : SLC test software, commands screenThe title bar of the commands screen should read “Searching for a reader”. At this point, the reader shouldbe powered.
© Copyright 2002, SIRIT Technologies : Manual version 2.03 Page 8 of 15First time operationOEM400 22.8 Powering for the first timeWhen power is supplied to the reader from an off state, both on-board LEDs D5 and D6 will illuminate. Lessthan one second after power is applied, D5 will turn off and D6 will remain illuminated to indicate that poweris present. If the power supply is able to monitor current, a draw of 70mA should be observed (whenoperating at RS232 levels).Returning back to the SLC test software, the title bar of the commands screen should now read “Reader –Type 9 V2.00 on COM1 at 57600 Baud” or similar, depending on the port and parameters that have beenused. If this message is not displayed, please refer to section 5 in order to determine the cause of theproblem.2.9 Set-up and testAssuming that the board is powered and the version string has been detected and displayed in the title bar,the next step is to ensure that the board is correctly reading tags. The simplest method of determining theperformance of the product is to use the reader test function (Figure 2-2) of the SLC test software. This isavailable from the Options menu.Figure 2-2 : SLC test software, reader test screenThe reader test is a convenient method of assessing the correct operation and performance of a OEM400product.To enable a test of particular tag, select the button of the tag you wish to test, which will then becomedepressed. When no tag is present, the ‘Fail’ counter will increment at a rate of approximately ten counts persecond and the timer will begin. To test the read range, position a tag (of the type selected) directly abovethe antenna. The ‘Pass’ counter will now increment and the horizontal bar display will begin to turn from redto green. The read range of the product can now be tested by moving the tag slowly away from the antenna.Ranges for supported tags can be found in section 4.2.

If there arestill problems with the board, please contact our technical support department.Q. The board LEDs do not illuminate on power-on.Check that the connector is wired correctly (see section 4.5) and that the wake-up pin (pin 7) is hard-wired to the +5V line, unless it is being used as a wake-up line. If the LEDs are still not illuminatedthen follow the download instructions in section 4 to download the latest firmware file.Q. The board communicates but will not read tags.Check that the antenna connection is secure and that the wiring is in good condition. If possible, tryreplacing the antenna with another and try again. Also ensure that the tag is supported by the reader(see section 1) and check that the tag is operational – it is best to try a selection of tags.Q. The board powers but will not communicate.Check that all wiring to the connector is secure and check the lines using a continuity tester. When inany doubt about communications, always use the SLC test software to help diagnose problems. Ifusing a Windows™ system then ensure that no other application (PDA synchronizer, etc.) is usingthe COM port. Also check that the baud rate of the hardware (see section 2.4) is the same as that inthe software.Q. The board reports random data from the tag and will only detect Microchip tags.This problem can occur when a noisy power supply is used or the antenna is not operating correctly,most likely a combination of the two. Follow the guidelines in section 2.2 to ensure that a suitablepower supply is used.Q. The read range is significantly less than the documented ranges.Either the antenna is not operating correctly, or the output power pins have been adjustedincorrectly. Check the values of the components as specified in section 2.5 and replace the antenna.Q. The board opens communications but reports random data.Check that the baud rate is correct and that the communication settings for the serial type (TTL orRS232) is correct, see section 2.2.
