9.Control Commands 9. Control Commands This device operates according to command signals sent from the host computer. Control commands and data are all sent and received in ASCII codes. 9-A Initialize Commands The following commands are used to change the status of the device immediately after the power is turned on: -1 Kinds of Initialize Commands Command -2 Format Explanation DL DLE DL∼ Sets the reading density. DD DC3 DD∼ Sets the difference in the reading density.
9.Control Commands -3 DC3 DD Command (Reading Density Difference Setting Command) [Explanation] This command is for setting the density difference allowable from the darkest mark in the CA and EA modes. After setting the difference, marks thinner than the setting are cancelled and those in the allowable range are all output. The density difference is set at "01" by default. In this case, mark data of the darkest density are output. This setting is not stored after the power is turned off.
9.Control Commands -4 DLE T Command (Timing Format Setting Command) [Explanation] This command is for setting mark read timing (timing mark type). If the DIP switch setting has not been changed, the setting by this command is not required when the power is turned on. When the T command is executed, the set value remains unchanged unless the device is reset or the power is turned off. When using the timing control type, be sure to set the read timing by this command.

Card empty (There is no card in the card hopper.) A jam error (32H) is assumed for the DF error.
10.Data Transfer Mode 10. Data Transfer Mode 10-A Data Transfer Commands The following commands are used to transfer data read from one card to the host computer: -1 Types of data transfer commands Mode Explanation A Outputs the number at a mark when the mark is detected on the 9 to 0 lines in one column, or outputs a space when no mark or more than 2 marks are detected. The data is output as an ASCII code. The X and Y lines are neglected. B Outputs data in one specified column in the A mode format.
10.Data Transfer Mode 10-B A Mode(1-byte Fixed Output Command) [Explanation] This command is for outputting the number at a mark when a mark is detected on the 9 to 0 lines in one column or outputs a space when no mark or more than two marks are detected. This device neglects marks and prints on the X and Y lines and outputs data as a 1-byte fixed length ASCII code for one column. Separators like STX and ETX can be added using the DC4 command.
10.Data Transfer Mode 10-C C Mode (Fixed Length Output Command) [Explanation] One column is divided in units of four lines. Existence of a mark on each line is indicated by "1" and non-existence is indicated by "0." The 4-bit unit is regarded as a 4-digit hexadecimal number, and the ASCII codes from 0 to F are output. Data are of fixed length of 3 bytes a column. (A 15-line postcard-sized card is a fixed length of 4 bytes a column. The 16th line, however, is always "0" as a dummy line.
10.Data Transfer Mode 10-D CA Mode (Fixed Length Output Command for Automatic Density Distinction) [Explanation] The data format is the same as the one in the C mode. This command is for automatically distinguishing mark density for one column. When there are several marks, it cancels light-colored marks of larger density difference than the set difference and outputs marks of smaller density difference than the set difference.
10.Data Transfer Mode 10-E E Mode (Variable Length Output Command) [Explanation] This command is for returning ASCII codes corresponding to marked line positions. Data are of a variable length corresponding to the number of marks. CR codes are added at break points between columns. When no mark is detected in a column, "a space + CR" is output. The correspondence between line positions and ASCII codes can be set in two ways as shown in the tables below by turning DIP SW6 on and off.
10.Data Transfer Mode 10-F EA Mode (Variable Length Output Command for Automatic Density Distinction) [Explanation] The data format is the same as the one in the E mode. This command is for automatically distinguishing mark density for one column. When there are several marks, it cancels light-colored marks of larger density difference than the set difference and outputs marks of smaller density difference than the set difference.
10.Data Transfer Mode 10-G ED Mode (Variable Length Output Command with Density Data) [Explanation] The data format is the same as the one in the E mode. One byte indicating density data is added after each mark data to output it in two byte units. Separators like STX and ETX can be added using the DC4 command.
10.Data Transfer Mode 10-H ES Mode (Variable Length Output Command by Density and Mark Data) [Explanation] The data format is the same as the one in the E mode. This command is for outputting mark and density data separately. The density data format is also the same as the one in the ED mode. Separators like STX and ETX can be added using the DC4 command.
10.Data Transfer Mode 10-I G Mode (EBCDIC Code Convert and Output Command) [Explanation] This command is for reading EBCDIC-based punched hole codes of one column and converting the codes into 1-byte ASCII codes to output them. This device outputs a space when a mark position does not agree with the EBCDIC code or when no mark is detected. Separators like STX and ETX can be added using the DC4 command.
10.Data Transfer Mode 10-J B Mode [Explanation] This command is for outputting data in one specified column in the A mode format after indicating a certain column. [Format] DLE B CR NI N2 (10H) (42H) (0DH) CR (0DH) N1N2 .... Specifies a certain column. 10-K D Mode [Explanation] This command is for outputting data in one specified column in the C mode format after indicating a certain column. [Format] DLE D (10H) (44H) CR NI N2 (0DH) CR (0DH) N1N2 .... Specifies a certain column.
10.Data Transfer Mode 10-M Other Commands -1 ENQ Command (Error Status Output Command) [Explanation] This command is for outputting the status after card feeding. The data are of 1-byte fixed length ASCII codes. Separators like STX and ETX can be added using the DC4 command. [Format] Host Computer This device ENQ CR Receive (05H) (0DH) Receive Data output # Error status For error statuses, see 8-B-2.
10.Data Transfer Mode -2 Timing Mark Count Check Commands ENQ T Command (Read Area Count Output Command) [Explanation] This command is for returning the number of read timing marks. Whether a certain record has a different timing mark count or not can be checked by checking the number of timing marks after the card feed command (? command) is issued. The data are of 3-byte fixed length ASCII codes. Separators like STX and ETX can be added using the DC4 command.
10.Data Transfer Mode -3 Sensor Status Check Commands ENQ S Command (Sensor Status Inquiry Command) [Explanation] This command is for returning the present status of the card sensor. (The existence of a card at each sensor position can be detected using this command.) The data is of a form of 1-byte ASCII numeric code + CR. "1" is returned when a card is detected or "0" when no card is detected.
10.Data Transfer Mode 1 Roles of sensors Sensor S1 : Located at the card hopper and detects that cards have been set. Sensor S2 : Located at the card feeding port and detects that card feeding has started. Sensor S3 : Located at the reader and reads data. Sensor S4 : Located at the card ejector and detects that cards have been ejected. DF sensor : Located between S1 and S2 and detects double-feeding. Cover open : Detects whether the top cover is open or not.
