In most cases, the PSC scanner is easily connected between the keyboard and display of the terminal. The use of Preamble/Postamble, embedded keyboard function codes or keyboard function records allow operation of the terminal without manual entry from the keyboard. In this mode of operations, the PSC scanner draws power from the terminal. Serial Communications Mode The PSC scanner can be configured by the user for a serial communication output. In this mode, the scanner can be connected to any device that accepts serial ASCII data at TTL voltage levels. RS232 voltage levels can be achieved by the use of an optional RS232 conversion pod. AutoSense® Mode The PSC scanner may be configured at the factory with PSC’s AutoSense® feature. AutoSense® operates with a passive stand for hands-free operation. When the scanner is placed in the stand, it becomes immediately active for reading any bar code label presented to it. The user can remove the scanner from the AutoSense® Stand and use it as a conventional hand-held scanner. When replaced in the stand, the scanner reverts automatically to AutoSense®. Wand Emulation Mode The PSC scanner can be configured by the user for Wand Emulation. In this mode, the PSC scanner can be connected to any device that accepts a wand signal input. Wand Emulation communication presents bar code data to a host device exactly as a wand does. This precludes the use of any option which adds information to the bar code symbol data (preamble, for example). A typical example of this would be to interface the scanner to a portable data terminal for remote data collection. Magnetic Stripe Reader Magnetic stripe reading capabilities are available with appropriate cabling. 06656 1 Unpacking Your package should include a scanner, interface cable, User’s Manual, and a plastic scanner holder. The unit should be inspected immediately upon receipt to determine if any damage has occurred during shipment. If damage has occurred, a claim should be filed with the carrier immediately. Retain the shipping box, since it should be used to return the scanner to the factory for service. Installation Keyboard Wedge In Keyboard Wedge mode the PSC scanner simulates keyboard keystrokes. Whether a person has pressed a key on the keyboard or data has been transmitted from the scanner is indistinguishable by the host device. When the PSC scanner is not transmitting data to the terminal the keyboard operates as if the PSC scanner was not attached. Installation of the PSC scanner should be completed by a user who is familiar with installing computer systems and cabling. Cable Installation 2 1. Turn off power to the terminal to which the PSC scanner will be connected. 2. Verify that you received the correct cabling. The cable supplied for keyboard wedge installation is referred to as a “Y” cable. 3. Connect the modular plug to the PSC scanner. Insert plug into the rectangular opening in the bottom of the scanner handle. 4. Unplug the keyboard from the terminal and replug the keyboard into the short leg of the “Y” cable that mates with it. 5. Plug the remaining long leg of the “Y” cable into the terminal where the keyboard was connected. 6. Arrange the fully connected unit so that all cables run freely. User’s / Programming Guide Connecting the Power Supply If supplied, plug the connector from the external power supply into the receptacle located on the housing connector. Then plug the power supply into a power source. Connecting a Magnetic Stripe Reader If a detached Magnetic Stripe Reader (MSR) is to be used, plug the connector into the MSR receptacle located on the housing connector. Terminal Power-Up Sequence Turn on the power to the terminal to which the PSC scanner is connected. The unit will issue a series of beeps which are intentional and indicate that the terminal/keyboard power-on reset routines have been completed. Programming for Terminal Type NOTE If this is a first-time installation, it is NECESSARY to program the PSC scanner for use with the connected terminal. Proceed as follows: 1. Using the Keyboard Wedge Parameters menu given in the Keyboard Wedge Parameters Section scan: WEDGE MODE ENABLE (CE) This sets the PSC scanner into a Keyboard Wedge interface mode. 2. NOTE 06656 Select the terminal type by next scanning the appropriate symbol for your terminal. Scanning Reset to Default (ZA) will cause the PSC scanner to revert to Keyboard Wedge mode with a PC-AT terminal type. 3 Serial Communications The PSC scanner provides the user with two different serial communications options: Serial TTL and Serial RS232 communications. Serial TTL Mode Serial TTL is a serial communications interface that uses TTL/CMOS voltage levels ranging from 0 to 5 volts. The user can select a normally high (default setting) or normally low (inverted) voltage levels. Serial TTL communications mode uses different cables than those used in keyboard wedge applications. To configure the PSC scanner in a Serial TTL mode, the user must have the appropriate cable with the correct signal pinouts in order to interface the scanner to the host terminal. To program the PSC for Serial TTL communications, the user must first identify the serial communications parameters supported by the host terminal. Typical parameters are the baud rate, parity and number of bits in the data word. These parameters are discussed in the section on Serial Communication Parameters. The PSC scanner has the added versatility to enable the user to select the quiescent voltage levels for interfacing with terminals that require inverted signals. Serial RS232 Mode The PSC scanner can also be used in an RS232 environment by converting the serial TTL voltage levels to RS232 voltage levels. For this installation, the user needs an optional cable, an adapter pod, and a power supply. When the PSC scanner is operated with the RS232 adapter pod, the same serial communications parameters apply as those used in a serial TTL environment. The only difference is that the RS232 adapter pod inverts the polarity of all the signals passing through it. Therefore, the user needs to program the scanner for serial communication, normal polarity (symbol CA). RS232 levels are available only in full continuous power mode. 4 User’s / Programming Guide AutoSense® Operation AutoSense® is a factory installed feature requested at time of order. It provides for hands-free or handheld operation. AutoSense® is activated by scanning the Enable AutoSense® symbol. The scanner will respond by emitting a continuous, low level red beam of light known as the trigger beam. AutoSense® is deactivated by scanning the Disable AutoSense® symbol. When the AutoSense® feature is used with PSC’s AutoSense® stand (specifically designed for standard and HP scanners), the user must first attach the plastic scanner holder to the bracket of the stand as shown in Figure 1, next page. The scanner is then mounted into the holder. Insure that the trigger beam is aimed at the reflective tape affixed to the stand. AutoSense® is now ready to automatically scan bar code labels presented to it. When the trigger beam is broken by the bar code label, the scan beam will automatically engage and decode the bar code symbol. Any time the scan beam disappears, whether by a decode or by a scan beam timeout, the automatic trigger must be re-enabled by allowing the trigger beam to sense the reflective tape. While AutoSense® is activated, the user is able to remove the scanner from its holder and use it for handheld scanning operation. When the scanner is removed from the AutoSense® holder, the trigger beam will be broken and the scan beam will automatically be engaged. If the scanner does not decode a bar code symbol, the scanning beam will turn off after two to six seconds. Scanning is re-initiated by manually pulling the trigger. When the scanner is replaced into the holder AutoSense® will be automatically re-engaged when the trigger beam senses the reflective tape. NOTE 06656 When the scanner is powered from a battery, such as in a hand-held terminal, AutoSense® should be disabled. In a battery powered application, the user is strongly recommended to use the power conservation feature of scanner operation. Power conservation reduces power draw from the battery between scans to extremely low levels. AutoSense® will function only in full power mode. 5 NO Enable AutoSense® NN Disable AutoSense® To use this mode of operation properly, the user must first attach the plastic scanner holder to the bracket of the stand as shown in Figure 1. The (NO) Enable AutoSense® programming symbol is scanned until the green “Good Decode” light blinks. This will activate the trigger screen. The scanner is then placed into the holder and the user must check that the red laser beam is aimed at the reflective label affixed to the stand. The AutoSense® is now ready to read labels presented to it. Figure 1. The PSC AutoSense® Stand a. b. c. 6 Riser sub-assembly Scanner holder Scanner d. e. Reflective tape Stand base User’s / Programming Guide Wand Emulation Operation To operate the PSC scanner in Wand Emulation the user must first turn off the powerto the host device and then detach the scanner from the host device by removing the cable from the scanner. The proper Wand Emulation cable must be connected between the scanner and the portable data terminal for remote data collection. If using an optional Smart Cable, the scanner automatically switches to Wand Emulation. Specific Wand Emulation parameters may still need to be set. If using a cable without Smart Cable switching, the user must then configure the scanner to its Wand Emulation mode by scanning the symbol CC. CC Same Code Wand Emulation This symbol activates the following default parameters: Code Type = Same Code Wand Emulation Code type, bar code polarity, and transmission rate can each be set for Wand Emulation. Menu symbols for these parameters are found in the section on Wand Emulation Parameters. When the user with a Smart Cable again connects to the host device, the scanner will automatically revert to the original communication mode. Without Smart Cable, scan the appropriate programming symbol. CE Enable Wedge CA Enable Serial Mode 06656 7 Setup Overview General setup parameters are divided into Keyboard Wedge options (communication to host through the terminal keyboard), Wand Emulation options (communication between the scanner and the host system’s decoder), and Serial Communication options (communications direct to the host system). Default options are denoted throughout the manual as follows: — Keyboard Wedge @ — Wand Emulation # — Serial Communication * Wedge Mode Options Several wedge mode options are available. Consult the Keyboard Wedge Parameters section for a complete list. Wand Emulation Options The available wand emulation options, listed below, are found in the section Wand Emulation Parameters. Bar Code Polarity • Black High • White High Transmitted Code Type • Same Code Wand Emulation • Converted to Code 39 (full ASCII) Simulated Scan Rate 8 • 5 inches per second • 10 inches per second • 15 inches per second • 20 inches per second • 50 inches per second • 70 inches per second User’s / Programming Guide Data Synchronization • Disable Data Synchronization • Enable Data Synchronization • Active Polarity High • Active Polarity Low Serial Communication and Wedge Options The following communication options are used to define how your PSC scanner communicates with the host system through its serial interface or its keyboard wedge interface. A message transmitted from the scanner upon a successful decode has the following format: Prefix Terminal ID Preamble Code ID Data Postamble Suffix Some of these attributes, e.g., prefix, preamble, etc., may not be required or may vary from one host system to another. The parameter selection process allows you to tailor these elements for the particular requirements of your host system. You may also program an intercharacter delay to prevent data overrun problems with your host terminal. Options specific to serial communications are: Baud Rate Protocol Parity Inverted Serial Stop Bits External Trigger Word Length Buffering Level Each of these options is discussed in greater detail in the section on Serial Communication Parameters. 06656 9 Symbologies The bar codes that can be read by PSC’s bar code scanners include: Code 39 Code 93 Interleaved 2 of 5 Code 128 Standard 2 of 5 Codabar UPC-A, UPC-E Code 11 EAN/JAN MSI/Plessey A complete list of the related options and the instructions for setting them are provided in the section on Symbologies. NOTE 10 Scanning problems are most often caused by poor quality bar code symbols. If scanning problems arise, test your bar code system using the high quality bar code test symbols supplied in this manual or contact your PSC Customer Service representative. User’s / Programming Guide Parameters Selection Guidelines Three basic steps must be followed when selecting parameters for your scanner. 1. Review this manual to be sure you understand the terminology. 2. Review the requirements of your host system, with a technical expert from your company, if necessary. This will enable you to determine if any of the factory default settings must be altered. 3. Enable or disable the relevant parameters by scanning the appropriate menus. This operation is described in more detail in the following example. Examples Assume that the beeper volume is too loud at its default setting. To change the beeper volume from its default value of loud to a setting of low, locate the beeper volume bar code menu in the General Parameters section. Then scan the label to the left of Beeper On, Volume Low. The correct label is reproduced below. AB Beeper On; Volume Low NOTE When enabling or disabling a parameter, be sure the scanner beam illuminates only one bar code symbol at a time. The layout of this manual minimizes accidental multiple-label scanning. A successful scan is indicated by two short-high beeps. An unsuccessful scan produces no beeps and requires you to rescan the Beeper On; Volume Low bar code. Most parameters are modified in this way, and you may resume normal bar code scanning when no further modifications are desired. Some parameters require multiple scans to modify a setting; for example, Intercharacter Delay. If you wish to set this parameter to 5 milliseconds (msec.): 06656 11 1. Scan the bar code beside Intercharacter Delay = XX and listen for one short-high beep. 2. After the beep, scan the bar code beside 0 on the Digit Selection page and listen for one short-high beep. 3. Still at the Digit Selection page, scan the bar code for 5 (the last argument in the command) and listen for two short beeps. Your PSC scanner does not have a distinct programming mode. Instead, it automatically recognizes and reacts to the labels you scan. If, for example, you scan INTERCHARACTER DELAY = XX and then scan a normal data label, a normal tone is emitted in response to the data label, and the programming command is ignored. No special exit code is required to resume normal operations. 12 User’s / Programming Guide Serial Communication Reset Default To program the communication mode for serial asynchronous communication, scan the following label: CA Select Serial Output Baud Rate There are seven standard serial communication baud rates to select from. Your scanner and the serial host computer must be set to the same baud rate. Select the correct rate. DA Baud Rate = 300 Baud DB Baud Rate = 600 Baud DC Baud Rate = 1200 Baud DD Baud Rate = 2400 Baud DE Baud Rate = 4800 Baud DF Baud Rate = 9600 Baud * DG Baud Rate = 19200 Baud 06656 13 Data Transmission Serial transmission data is composed of three of four different elements, depending upon host system requirements. These elements are the START bit, DATA bits (7 or 8 bits), OPTIONAL PARITY bits, and STOP bit (s) (1 or 2 bits). The PARITY bit is used for error detection (e.g., data altered in transmission), but is not required by all systems. A parity bit, if required, will be in one of the following four formats: If your system requires a WORD length of 7 bits, one or two STOP bits, and a PARITY check, select the appropriate option from Table 1. Table 1. 7 Bit Options Data Stop Bits 7 1 Odd ED 7 1 Even EC 7 1 Mark EB 7 1 Space EA* 7 2 Odd EH 7 2 Even EG 14 Parity Option User’s / Programming Guide Table 1. 7 Bit Options Data Stop Bits 7 2 Mark EF 7 2 Space EE Parity Option If your system requires a WORD length of 8 bits, 1 or 2 STOP bits, and PARITY check, select the appropriate option from the table below: Table 2. 8 Bit Options Data Stop Bits 8 1 Odd EL 8 1 Even EK 8 1 Mark EJ 8 1 Space EI 06656 Parity Option 15 If your system requires a WORD length of 8 bits and 1 or 2 STOP bits, but no PARITY, select the option below: Table 3. 8 Bit, No Parity 8 1 8 2 None EM EN PARITY check is not possible with this combination of STOP bits and WORD length. Some receiving equipment requires inverted serial communication signals. CD Inverted Serial Communications Communications Protocol XON/XOFF Protocol controls data flow between your PSC scanner and a serial host computer. If Protocol = XON/XOFF is selected, the scanner recognizes the ASCII XON/XOFF characters. The host may then stop transmission with XOFF and resume with XON. Controlled data flow is achieved between devices when the receiving device sends ASCII XON/XOFF codes to the transmitting device. In other words, when the receiving device is unable to accept data, it sends on XOFF code to inform the host to temporarily suspend data transmission. When the receiving device “catches up,” it sends an XON code to inform the host that it is again ready to accept data. An advantage of this protocol is that additional hardware is not required for implementation; only transmit, receive, and signal ground are required. 16 User’s / Programming Guide CTS Like XON/XOFF protocol, CTS protocol is a mechanism used to control data flow out. The CTS input is used to inform the scanner that the host terminal is ready to accept scanned data. When CTS (+) protocol is selected, the scanner waits for a low level on its CTS input before transmitting data. When CTS (-) is selected, the signal polarities are reversed and a high level indicates data may be transmitted. The CTS protocol may be programmed independently of the RTS protocol; however, the signal polarities must be the same. You may not select CTS (+) and RTS (-). RTS The RTS output from the scanner may be programmed to operate in one of three different modes. In the default mode RTS signals when the scanner is ready to receive commands or data. In the second mode, RTS is in a fixed state. In the third mode, RTS signals when the scanner has data to transmit. The RTS modes are independent of the CTS protocol. However, you must select the same active state for RTS as for CTS. You may not select CTS (-) and RTS fixed low. If CTS (-) is selected, then the active state for RTS will be high. The specified levels are at the modular connector and are inverted when using an RS232 converter pod. NOTE HA CTS Protocol = None* RTS low indicates scanner ready to receive data HB Protocol = XON/XOFF HC Protocol = CTS (-) 06656 17 HD Protocol = CTS (+) HG RTS always low HH RTS always high HI RTS high indicates scanner ready to receive data HJ RTS low indicates scanner has data to transmit HK RTS high indicates scanner has data to transmit Another flow control option is available. If enabled, the stop/go protocol disables the trigger after every successful scan. The trigger is then re-enabled with a serial ‘BG’ command in formatBG . BS Disable Stop/Go Protocol* BT Enable Stop/Go Protocol 18 User’s / Programming Guide Label Buffering The user may select one of three levels of serial buffering. With Full Buffering (the default) selected, the scanner will place all scanned labels into a buffer for transmission. This allows the operator to continue scanning even though the previous label may not have been transmitted yet. Scanning will continue normally until the buffer is full, then scanning will stop. Scanning will continue when enough space is available for the current label. When No Buffering is selected then scanning will be stopped until the current label is completely transmitted. When One Label Buffering is selected the scanner will allow the operator to scan one more label in addition to the label already in the transmit buffer. In other words, one label may be scanned beyond the label being transmitted. NE Full Buffering NF No Buffering NG One Label Buffering No Read Option The scanner can be programmed to send a no read message (‘NR’) upon a scan that does not result in a good read. NX Enable No Read NY Disable No Read * 06656 19 Menu Commands Parameter Messages In serial mode, most menu commands when scanned will provide a confirmation message to the host along with the ACK. This feature can be enabled or disabled. BA Enable Parameter Messages * BB Disable Parameter Messages External Trigger Operation External trigger operation enables an external device to control scanning. External trigger is controlled by applying an external trigger signal to the CTS input (with external triggering enabled). When active, this signal causes scanning to begin just as if the scanner’s trigger were depressed. Scanning continue until a label is decoded or the external trigger signal is deactivated. In the event of a decode, the trigger signal must be deactivated for a minimum of 50 milliseconds before another scan can be attempted (“tying” the trigger signal active does not cause continuous scanning and decoding). When EXTERNAL TRIGGER(+) is scanned, scanning begins when a high level input is applied to the CTS input. Conversely, when EXTERNAL TRIGGER(-) is scanned, scanning begins when a low level is applied to CTS. When CTS is not connected, it is treated as if a high level is applied. The voltage levels given are at the modular connector. If an RS232 converter pod is used, then the levels are inverted. HA Disable External Trigger#*@ HE External Trigger(+) 20 User’s / Programming Guide HF External Trigger(-) General Parameters Intercharacter Delay Certain terminals and computers require an intercharacter delay to simulate the effects of keystroke delays. Choosing an intercharacter delay causes the characters to be sent at the slower speed required by the device to which you are interfacing. GA No Intercharacter Delay NOTE GB To set Intercharacter Delay to other then zero, scan the label below and then scan two separate digits from the Digit Selection page (99 maximum). Intercharacter Delay = XXMEC Intercharacter delay cannot exceed 99 milliseconds. NOTE Interlabel delay allows user to program a delay between transmitted labels. GC No interlabel delay *@ GD Set interlabel delay 0-9.9 seconds 06656 21 Transmission Mode Full Duplex or Half Duplex This section pertains only to models with a Liquid Crystal Display (LCD) NOTE Transmission mode selects either full or half duplex operation regardless of interface. In the half duplex mode, the decoded message is sent simultaneously to the display and to the host computer. In the full duplex mode, the message is sent to the host computer. In send mode, the host always has the capability to send a message directly to the LCD. The advantage of the full duplex mode is that the display shows the message received by the host. In the half duplex mode you can see that the message has been sent but there is no confirmation that it was received. The disadvantage of the full duplex mode is simply that the host computer must be programmed to relay the message back to the scanner. NA Transmission Mode = Full Duplex NB Transmission Mode = Half Duplex *# For models which do not have an LCD, parameter selections NA and NB have no effect. NOTE System Status To examine the configuration of your system, scan the appropriate option. When Option ZB is scanned, a list of currently programmed parameters is sent to the display device. Scanning ZB may interfere with your terminal software, depending on your application. 22 User’s / Programming Guide ZB Display Configuration When Option ZC is scanned, the program version followed by carriage return-line feed characters (CR-LF) is sent in the format SP<###> (WDHB 3.86, for example). ZC Transmit Version Number Power Consumption You may choose one of two Power Consumption modes. Option @A supplies full power to the scanner at all times; Option @B allows the unit to revert to a standby mode after a successful read. This mode is a power conservation feature. @A Enable Continuous@ Full Power @B Enable Standby *# Laser Redundancy For a successful decode to occur when Laser Redundancy is enabled, two laser scans of the bar code must match. Because the laser scans a label many times a second, you will notice little or no change in the speed of the decode. Laser redundancy can be used to enhance the security of the bar code reader. BC Disable Laser Redundancy *#@ BD Enable 2 Times Laser Redundancy 06656 23 BE Enable 4 Times Laser Redundancy Laser Timeout The scan beam will activate in response to a trigger pull. The beam will automatically deactivate after a label is decoded. If a label is not decoded., the scan beam will timeout and deactivate after several seconds. Scan the following labels to control the length of the timeout. BH Set Scan Beam *#@ Timeout to 6 Seconds BI Set Scan Beam Timeout to 4 Seconds BJ Set Scan Beam Timeout to 2 Seconds BO Set Scan Beam Timeout to 1 Second BW Set Scan Beam Timeout to ½ Second Beeper Operation Scan one of the options below to modify beeper operation. AA Beeper Off AB Beeper On; Volume Low 24 User’s / Programming Guide AC Beeper On; Volume Medium AD Beeper On; Volume Loud *#@ Message Formatting Message formatting describes how to format the data (decoded string) that is sent from the scanner to the host. The programmable options DO NOT apply in Wand Emulation. NOTE Prefixes and Suffixes Prefix Terminal ID Preamble Code ID Data Postamble Suffix Prefixes, Suffixes, Preambles and Postambles are programmable attributes that are transmitted along with the decoded label data to the host device. These attributes are handled differently whether the scanner is configured for serial mode or wedge mode. When configured for wedge mode these attributes are sent as keystrokes. The scanner automatically translates the ASCII characters into keystrokes before sending data to the host. Refer to the keystroke translation tables for non-printable ASCII characters. 06656 25 Prefix A prefix is a subset of the preamble normally formatted to some industry standard, i.e., it is represented by a specific ASCII code. An example of a prefix is the STX (Start of Transmission) code. IA Prefix = None*# IB Prefix = STX IC Prefix = SOH Suffix A suffix is a subset of the Postamble. Like the prefix, it is normally assigned a specific ASCII code. Examples of suffixes are CR (Carriage Return) and LF (Line Feed). MA Suffix = None # MB Suffix = ETX MC Suffix = CR MD Suffix = LF ME Suffix = HT 26 User’s / Programming Guide MF Suffix = CR and LF * Users also have the ability to select any ASCII character for use as a suffix. Scan the MJ label, then scan two labels from the Hexadecimal Conversion Table representing the character needed for the suffix. MJ Select Programmable Suffix Character Certain specialized applications require a two character suffix of ETB NUL. Scanning MI provides this. MI Select Suffix = ETB NUL Terminal ID Terminal ID characters are used to identify individual scanners when more than one scanner is interfaced with the host system. Options available are none (DISABLED) or digits 01 through 99. JA ID Character = Disabled*# If you scan the label below, you must also scan two of the digits from the Digit Selection page. NOTE JB 06656 ID Character = XX 27 Code Identifier A code identifier may optionally be transmitted with the message. This option is provided so a host computer can identify the type of bar code scanned, as well as the encoded information. Scan Option FA to disable the code identifier. FA Disable Code ID # * Scan Option FB to enable the code identifier. FB Enable Code ID The table below shows the default code-identifier character assignments. These can be changed using the procedure found in the Symbology Identifier Section. Table 4. Code Identifier Characters SYMBOLOGY CODE IDENTIFIER Code 39 a Code Interleaved 2 of 5 b Code Standard 2 of 5 c UPC/EAN/JAN d Code 128 f Codabar h 28 User’s / Programming Guide Preamble or Postamble Selection Preambles and Postambles are composed of up to four ASCII characters. Each ASCII character is encoded as two hexadecimal numbers. Use the Hexadecimal Conversion Table in Appendix A to look up the hexadecimal equivalent. NOTE If you select a Preamble or a Postamble you must scan four ASCII characters, even if the Preamble or Postamble is less than four characters in length. This is done by scanning in null (NUL) characters for the additional characters. For example, if your Preamble is “AB” (in ASCII code), scan A, then B, then two null characters, or 4,1, 4,2 0,0 0,0 hexadecimal. Preamble A Preamble is a string of characters that prefixes a message that is transmitted to the host. The sequence and number of characters in a Preamble is determined by the type of host system. Although not all systems require a Preamble, those which do will only receive messages with the correct Preamble. The maximum preamble length is four characters. KA Preamble = None*# KB Enter Preamble IMPORTANT Scan Enter Preamble to enter a Preamble, then refer to the Hexadecimal Table in Appendix A. Postamble A Postamble is similar to a Preamble, except that it appended to the message which is transmitted to the host. Its maximum length is also four characters. 06656 29 LA Postamble = None*# LB Enter Postamble IMPORTANT Scan Enter Postamble to enter a Postamble, then refer to the Hexadecimal Table in Appendix A. 30 User’s / Programming Guide Serial Commands General Serial Command Format Serial Commands are only accepted by the PSC scanner when in serial communications mode. Serial commands take the form: STX ESC LT1 LT2 ETX (Note: STX = ^B; ETX = ^C) STX, ESC, and ETX are ASCII codes whose values are 02H, 1BH, and 03H, respectively. LT1 and LT2 are uppercase ASCII letters (commercial A and @ are the same as those printed in earlier sections of this manual under their corresponding menu bar code labels). The ESC code that follows the STX code identifies this as a command. Some commands require parameters such as minimum and maximum code lengths, and strings of hexadecimal characters. When parameters are required by the command, they immediately follow LT2. There are never spaces within serial commands. ACK/NAK The scanner provides ACK/NAK protocol during serial programming in order to provide feedback to the host computer which is programming the scanner. ACK/NAK protocol provides two vital functions. First, it provides the host with positive acknowledgment that its commands are being accepted and acted upon. Second, and perhaps more important, it ensures that the host will not issue commands to the scanner more quickly than the scanner can process them. For example, every time the scanner receives a correct command, it modifies its internal EEPROM, a function that takes about one second. At 9600 baud, the host can easily issue commands to the scanner faster than they can be processed. If after issuing each command the host waits to receive an ACK or NAK code before issuing the next command, the scanner cannot be overrun. If XON/XOFF or CTS/RTS Protocol is being used, the scanner cannot be overrun by programming commands. However, the host is not provided with feedback as to the outcome of its commands. The ACK/NAK protocol is quite simple. Whenever the scanner receives a correctly formatted command, it sends a confirmation message followed by an ACK (06H) code. 06656 31 Beeper Off CR-LF Ack If the scanner receives an unknown or improperly formatted code, or if the required parameters are missing or out-of-range, it sends a NAK (15H) Code. Command Function STX ESC PC ETX Enable I 2 of 5 with check digit STX ESC PD12 ETX Set I 2 of 5 minimum length to 12 STX ESC PE14 ETX Set I 2 of 5 maximum length to 12 STX ESC KB31323334 ETX Set Preamble to ‘1234’ STX ESC LB61626364 Set Postamble to ‘abcd’ Serial Commands to Use with Caution Some of the commands in this manual should not be used as serial commands because of the consequences they produce. All PSC scanners use the same hardware components to implement both serial communication and wand emulation. This means that all serial communication functions are disabled during wand emulation, and vice versa. Because of this, issuing any of the commands in Table 5 causes the scanner to enter its Wand Emulation mode, thereby disabling serial communication. CB Wand Emulation, Code 39 Output CC Wand Emulation, Same Code Output Furthermore, because the scanner acts upon a command and then sends ACK or NAK, neither or these codes will be transmitted in response to any of the above commands. In Table 5 only the command letters are listed; the complete command is prefixed with STX ESC, and suffixed with ETX. Because it is not possible to set (via serial command) two Wand Emulation parameters (emulation speed and polarity, for example), scanners to be used in Wand Emulation environments must be programmed by scanning labels from this manual. 32 User’s / Programming Guide Power Standby and Serial Commands When the scanner is programmed for standby power operation (@B), the first character of the command is used to “wake-up” the scanner; it is not properly received by the scanner’s CPU. Therefore, when there is any possibility that the scanner is in standby mode, an extra space code should be transmitted before STX to ensure the scanner is “awake” before sending commands to it. If the scanner is not being operated in standby mode, the space has no effect on commands (space prefixed commands are properly decoded). Having sent the space code to “wake-up” the scanner, a 150 to 200 millisecond pause must be observed to allow the scanner’s CPU to complete its initialization tasks, during which time it is unable to accept serial commands before issuing the programming command. Failure to observe this delay causes the scanner to ignore the incoming command. Communication Parameter Changes All commands which affect serial communication are acted upon immediately. Therefore, when changing communication parameters (baud rate, word length, parity, etc.), the scanner will send the ACK Code, using the newly implemented communication parameters. There should be enough of a delay from the issuance of a communication parameter setup command for the properly programmed host computer to modify its internal parameters and correctly receive the ACK code sent by the scanner. This is due to the internal, one second delay required for the scanner to update its internal EEPROM. Manual Scanning Interaction The decoder firmware makes no attempt to resolve conflicts between serial programming commands and manually scanned menu labels. If you plan to scan menu labels from the PSC Operator’s Manual, do not attempt serial programming, and vice versa. Serial commands are given priority over pending menu labels. For example, if you scan the menu label SET I 2 of 5 MINIMUM LENGTH and the scanner is waiting for a two-digit, minimum length code when a serial command is issued, the serial command is acted upon and the pending manual command SET I 2 of 5 MINIMUM LENGTH is ignored. 06656 33 Keyboard Wedge Parameters Scan symbol CE to enable Keyboard Wedge mode. Next, select a terminal type by scanning the symbol CF for IBM PC-AT or PS/2 models 50/60/80; or symbol CG for PC-XT type terminals.

Should a scanned bar code label have alphabetic characters, they will be presented to the computer as if they had been typed at the keyboard. They will be affected by the Caps Lock key. If the scanned label has lower case alphabetic characters AND the Caps Lock key in ON, then the alphabetics will be presented as upper case. With the Caps Lock key ON, the user may required that the scanned alphabetics are presented to the computer exactly as they are encoded in the label. This is accomplished by scanning EO – Shift Alphabetic Characters. 36 User’s / Programming Guide EO Shift Alphabetic Characters EP Normal Alphabetic Characters* NOTE In some models of scanner, the wedge output is capable of two types.

If you select a one character identifier, then scan zero (null) twice for the second character. 06656 55 To find the hexadecimal values for the characters turn to the Hexadecimal Conversion Table. The procedure for selecting a symbology identifier is identical to the procedure for selecting Preambles and Postambles. The similar difference is that symbology identifiers are a maximum of two characters, not four. NOTE Scanning the ZA (Result to Default) programming symbol will set all symbology identifiers back to PSC defaults as given in Table I and disable the transmission of the symbology identifiers.

The Memory Module option allows the 5300 series scanner to store decoded labels in an internal battery backed up RAM. The stored buffered labels can then be transmitted some time later. The user may also choose an interlabel transmission delay in cases where the transmission rate of the buffered decoded label is faster than the receiving equipment. Switching to the Memory Module mode is achieved by scanning the Enable Memory Module symbol. The Memory Module is cleared every time Memory Module is enabled. While in Memory Module mode, the scanner will store in its internal memory all scanned bar code labels. The user can transmit the stored labels by scanning the Send Memory Module symbol. When the transmission rate is faster than the receiving equipment, the user can program a delay that will occur after each label. The delay is programmed by scanning the Interlabel Delay symbol (see the Intercharacter Delay page of the Setup Parameters section), followed by two digits (see Digit Selection page) to set the delay duration. The allowable range of values is 00 to 99, where 99 corresponds to a delay of 9.9 seconds. In order to restore the scanner to normal operation, the user needs to scan the Disable Memory Module label. Also the user may clear the contents of the Memory Module by scanning the Clear Memory Module symbol or by disabling and enabling Memory Module. Stored labels are cleared whenever Memory Module is enabled. The stored data in the Memory Module cannot be transmitted through the Wand Emulation output. NOTE CAUTION 62 The Memory Module feature is to be used only with the Memory Module mode. When used with scanners without this optional mode, programmed instructions will be damaged.

You may also find a Marker Beam useful when scanning through showcase glass or bar code menus with labels in close proximity. This feature is available in all scanners without factory authorization. To activate the Marker Beam, the user must also program the duration of the Marker Beam. First, the symbol Enable Marker Beam is scanned and then followed by scanning one digit symbol from the Digit Selections table. Each digit symbol represents the desired time duration of the Marker Beam in milliseconds. To deactivate the Marker Beam, the user must scan the Disable Marker Beam symbol. For successful programming, the user must hold the trigger down for two seconds after scanning.
