    Figure 3. CR-510 (Rear View) DIP Switches Position the DIP Switches to set the baud rate. The DIP Switches are located behind the metal plate (see Figure 7 for details). The CR-5l0's baud rate must match the baud rate of the Computer. (See Setting Up the CR-510 for details.) RS-232C Connector Connect the CR-510 to the TRS-80 via this connector using the appropriate interface.

    Figure 6B. Card Retainer Installation Setting the DIP Switches At the rear of the CR-510 are the DIP Switches which let you set the baud rate. The CR-510's baud rate must match that of the Computer it is connected to. For example, if you have set the baud rate of a TRS-80 Model III to 4800 baud, you must set the CR-510's DIP Switches to the 4800 baud setting.

    3/ General Information Thus chapter will provide information on using card readers in general and the CR-510 in particular. This includes hints on marked or punched card characteristics and maintenance. It also provides two test features that confirm the reliability of your CR-510 system. Preparing, Handling and Maintaining Cards Using card readers requires that you become familiar with the characteristics of cards and how to take care of them.

  • Page 18: Card Feed Modes

    Card Feed Modes The CR-510 can read cards in one of three modes: • Single Feed • Demand Feed • Continuous Feed. How to select these modes is outlined below. Single Feed Mode In this mode, the CR-510 reads a single card every time you press the START/STOP button. The READY lamp will illuminate, indicating that the CR-510 is ready to read a card.

    Figure 11. CR-510 Stripper Plate Cleaning the Rubber Roller Another condition that can inhibit the proper reading and feeding of cards is when the rubber roller (Figure 12) becomes contaminated by the graphite residue from previous card readings. We recommend periodic cleaning of the roller to insure proper frictional contact between cards and the roller.
  • Page 20 Included in the CR-510 package is a small vial of cleansing detergent and a soft cloth. These are specifically for cleaning the rubber roller and the read head assembly. 1. When cleaning the rubber roller, make sure that the unit is turned off and the power line is disconnected or unplugged.

  • Page 25: 4/ Using The Cr-510

    4/ Using the CR-510 Many of the features of the CR-510 are software dependent. Switch settings and loading procedures depend on your particular application. However, there are certain aspects which are general to all applications. We will discuss these aspects in this section. Programming the Card Reader To use the Card Reader with your computer, you must have a driver routine which controls information flow to and from the unit.

  • Page 26: Format Commands

    In such a case, the READY light on the front panel will blink. To clear the error, the computer must first receive the status code (either as part of the normal transmitted data, or by requesting status with the STA command). It then must send a valid command to the Card Reader. The following table contains a list of the commands that can be sent (via the TRS-80) to the CR-510.
  • Page 27 To make the Card Reader more versatile, you can specify a special format which retranslates the row marks on the cards into different fields. These fields are then translated into the actual bytes that will be transmitted by the Card Reader. The format commands are: ASCII Converts the Hollerith card data into its ASCII equivalent.
  • Page 28 Field One represents the first byte and Field Two represents the second byte. The least significant row of each field (row 9 and row 3) correspond to bit 0 of each byte. In addition, to fill out each byte, bit 6 is set to 1, and bit 7 is set to 0. This provides a character range of codes 64 through 127. HeXadecimal 1 HXl separates the 12-chad/column Hollerith card data into three fields, from right to left as follows: Field One represents byte 1, Field Two represents byte 2, and Field Three represents byte 3.
  • Page 29 (•means the row is marked.) Marking more than one 0-9 row in a given column will result in a reverse slash. GRader 1 Converts the data into two 6-bit fields, reading from right to left, as follows: Under this format, the Card Reader expects one marking per field. Byte 1 consists of the ASCII code of the character represented by the marked row of Field One.
  • Page 30 Under this format, the Card Reader expects one marking per field. Byte 1 consists of the ASCII code of the character represented by the marked row of Field One. Byte 2 consists of the ASCII code of the character represented by the marked row of Field Two. For example if Row 0 is marked, then Byte 2 is equal to 67 (the ASCII code for "C").
  • Page 31 Line Feed Off Disables line feed after the carriage return (no line feed is sent after each card is read). Line Feed On Enables transmission of a line feed character (ASCII code 10) following the carriage return. Unit Status is not returned with data. Unit Status is returned with data.

  • Page 32: Cr-510 Communications Overview

    Erase Previous Character The Hexadecimal value 08 (ASCII BS) will cause the previous character sent to the CR-510 to be erased. If it is the first character in a command string, it will be treated as a no-op. Status The following table lists the status conditions that can be returned to the computer if status is enabled (ST1) or an STA command is sent.

    ASCII data. Then, it will read the second card and transmit the ASCII data. The HX3 command (second string) will cause a command error and the front panel READY lamp will blink (since line two has an invalid command the PIK that follows HX3 will be ignored). The last PIK command (line 3) will return a reverse slash in lieu of data (the last card will remain in the hopper).

    Programmers' Guide The following information is included to help you adapt this software for use with your own card reader application. Chapter 4 of this manual contains complete information on the commands recognized by the CR-510. The files that are included on the enclosed diskettes are listed and described below. Some guidelines for using these drivers with your own applications are also given.
