SECTION 1. COMMANDS OVERVIEW

This manual describes the use of all the commands and programmable options available for the MICRImage Reader. The MICRImage commands can be classified into two general groups: Configuration Commands and Operational Commands.

CONFIGURATION COMMANDS

As the name implies, these commands are used to configure the MICRImage Reader. These commands can also be accessed using Insta-change checks and the MICRbase Setup Program for Windows (see below). Additionally, all the parameters and options controlled by the configuration commands can be factory set as specified by the user when ordering.

The current list of configuration commands follows for the standard unit (see Section 2 for a complete description of these commands):

• SWA – Switch A command

• SWB – Switch B command

• SWC – Switch C command

• SWD – Switch D command

• SWE – Switch E command

• SWF – Switch F command

• HW – Hardware command

The current list of configuration commands follows for the Ethernet and Modem Options (see Section 5 for a complete description of these commands):

• PR0 – MICR IP Address Fixed Value

• PR1 – MICR IP Address Source

• PR2 – MICR IP Subnet Mask Fixed

Value

• PR3 – MICR Subnet Mask Source

• PR4 – Gateway IP Address Fixed Value

• PR5 – Gateway IP Address Source

• PR6 – FTP IP Address Fixed Value

• PR7 – FTP IP Address Source

• PR8 – FTP User ID Fixed Value

OPERATIONAL COMMANDS

Operational commands provide access to additional parameters and options that control the operation of the MICRImage reader.

The current list of general operational commands follows (see Section 3 for a complete description of these commands):

• VR – Version command

• RS – Reset command

• LE – LED command

• DM – Disable MICR command

• FC – Format Change command

• SA – Save Configuration command

• PR12 – Filename Configuration

• PR20 – PR29 - Snippets

• PR30 – PR33 - Doc Size Limits

• PR34 – PR35 – MICR Line Technical

Options

• PR9 – FTP User ID Source

• PR10 – FTP Password Fixed Value

• PR11 – FTP Password Source

• PR13 – DNS1 IP Address

• PR14 – DNS2 IP Address

• PR15 – DMS IP Address Source

• PR16 – Phone #

• PR17 – User ID

• PR18 – User Password

• PR19 – FTP File Directory

• EM – Enable MICR command

• BLK – Block Command

• UNBLK – Unblock Command

MICRImage Check Reader

The following are operational commands that are image specific (see Section 4 for a complete description of these commands):

• TG – TIFF tag command

• TI – Transmit Image command

• FM – File Memory command

• SI – Store Image command

• SF – Send next image File command

• TC – Set file and timer counter

command

• IS – Image Status command

• AI – Append Image command

• BC – Bar Code command

COMMAND LINE SYNTAX

Unless otherwise noted, commands are “free form” in that spaces may be inserted between parameters, numbers, and file names (but not between digits). These spaces are ignored. Spaces within a string are retained.

Lower case letters are converted to upper case letters except in strings. Strings must end with ‘]’ or <CR>. If ‘\’ is used in a string, the character that follows it replaces the ‘\’. For example, if the command line has the string: Hello[World\] and \\us\\], the resulting string will be: Hello [World] and \us\.

All commands must end with <CR>.

INSTA-CHANGE CHECKS

The Insta-Change check is a MICR encoded document that contains commands and options used to set configuration parameters in the MICRImage Reader. Multiple commands and options may be contained on one Insta-Change check. Also, multiple Insta-Change checks may be required to configure some of the parameters.

When used, the Insta-Change checks are run through the MICR Reader the same as a standard check, and the options to be used are automatically configured. When the Insta-Change check is run through the MICR Reader and read successfully, the LED indicator will blink green. If the LED indicator turns red, the read is not successful. Try again or use a different Insta-Change check. To obtain Insta-Change checks, notify a MagTek representative and specify what option will be used.

MICRBASE SETUP PROGRAM FOR WINDOWS

The MICRbase setup program (P/N 22000021) allows the user to control all the programmable options available in the MICRImage Reader.

Section 1. Commands Overview

The program provides a graphical, user-friendly interface that hides the complexities involved in manually entering MICRImage commands. The user is no longer required to know the specific commands or the detail data associated with each command. However, the program still allows manual entry of commands for advanced users. For more detailed information, refer to the MICRbase Setup Program Reference Manual (P/N 99875102).

The MICRbase setup program may also be downloaded from the Internet at www.magtek.com under Software/Demo Programs.

MICRImage Check Reader

SECTION 2. CONFIGURATION COMMANDS

Configuration commands are used to setup configuration parameters in the MICRImage Reader. A complete description of these commands follows:

SWITCH COMMANDS

These commands control internal “software” switches used to configure the MICRImage reader. The switch commands include SWA, SWB, SWC, SWD, SWE, SWF, SWI, HW, FC, PR12, and SA commands.

When sending configuration data for a software switch, 8 ASCII bits must always be provided (“0”= hex 30, and “1”=hex 31). The MICRImage will execute the command but it will not reply.

For example, to execute the SWA command with configuration data, send the command as follows:

SWA 01010101<CR>

To make a switch command permanent, follow the switch command with the SA command (Save command) as follows:

SWA 01010101<CR> SA <CR>

If a switch command is sent without configuration data, MICRImage will reply with the current settings for that switch.

SWA COMMAND – HOST PORT PARAMETERS

This command controls the communication parameters for the RS-232 Host port. The parameters for this command are listed in Table 2-1.

Note

The MICRImage includes an RS-232 auxiliary port that can be configured in a similar manner using the SWD command.

Note

The new settings for the serial port will not become effective unless SWA has been saved and until the RS command is executed.

Baud Rate

The Baud Rate is one of eight speeds at which the MICRImage communicates with the host. The lowest speed is 1200 baud, and the highest is 115200.

Data, Stop Bits, and Parity

Data refers to the number of data bits used to transmit every character; the options available are 7 or 8. Stop Bits refer to the number of bits used to indicate the end of transmission for every character; the options available are 1 or 2. Parity refers to a means of detecting bit-level transmission errors for every character; the options available are None, Even or Odd.

CTS/DSR

When CTS/DSR (Clear to Send/Data Set Ready) is set to Ignore, the MICRImage sends data to the host without waiting for the CTS and DSR signals to be active. When CTS/DTS is set to Use, the MICRImage waits for the CTS and DSR signals to be active before sending data.

Section 2. Configuration Commands

Inter-character Delay

The inter-character delay is used to increase the time between characters transmitted from the MICRImage. The delay between characters is 13 ms for baud rates of less than 9600 and approximately 1ms for baud rates of 9600 and higher.

SWB COMMAND – MESSAGE FORMAT PARAMETERS

The SWB command controls the message format, shown in Table 2-2.

Control Characters and MICR Data

Control Characters may be added to the MICR data message. The characters are always in the following locations:

The control characters, descriptions, and hex values are shown in Table 2-3.

Table 2-3. Control Characters

CONTROL

CHARACTER

<STX> Start of Text 02 <ESC> Escape 1B <ETX> End of Text 03

<CR> Carriage Return 0D

<LF> Line Feed 0A

DESCRIPTION

HEX VALUE

For example, if <STX> and <CR> are set to YES, the message from the MICRImage will look like this:

Communication Modes

The selection of Comm Modes is a quick way of selecting multiple Control Characters. For instance, to send a carriage return/line feed pair after the data, you can specify Comm Mode 3.

Comm Mode 7, also known as Packet Mode, calculates an LRC (Longitudinal Redundancy Check), and appends it to the data message. Also, if a <NAK> (hex 15) character is received in this mode, the MICRImage will resend the last message.

Send Data After Error

The parameter Send Data After Error specifies whether the MICRImage will return data to the host after a read error. If YES is selected and the MICRImage reads a check with an error, the MICRImage will send the data back to the host. If NO is selected and the MICRImage finds an error, it will discard the data and nothing will be sent. The error conditions are listed in Table 2-4.

Table 2-4. Error and Status Codes

PRIORITY CODE TYPE DESCRIPTION

10 01 Error No MICR data: no transit and no account found

9 09 Status Mexican check 8 08 Status Canadian check 7 05 Error No transit, bad character, bad length, bad check digit 6 07 Error No account, bad character 5 04 Error Bad character in check number 5 04 Status No check number 4 12 Status Short Account (maybe caused by mis-parsed check#) 3 03 Status Low MICR signal, good read 2 10 Status Business check 1 11 Status Amount field present 0 00 Status No error, check OK

Section 2. Configuration Commands

Notes:

• The LED indicator will turn red on all error conditions.

• The absence of a check number is not considered an error.

• If a multiple error occurs, the error or status code with the highest priority is reported.

• All unreadable MICR characters are transmitted as an “?” ASCII character (hex 3F), except

for Format 00xx (See Section 5).

Send Status After Data Parameter

The Send Status After Data Parameter makes the MICRImage append a two-digit error/status code to the end of the MICR data. For most formats (See Appendix A) the error/status code will always be preceded by a forward slash (/). The error/status codes are listed in Table 2-4.

For example, if a Canadian check (code 08) is read and had no errors, and the MICR data is “1234567890”, then the message from the MICRImage will look like this:

1234567890/08

The status code is always at the end of the data, not the end of the message. For example, using the above conditions, with the message format set to send <STX> and <ETX>, the message from the MICRImage will look like this:

MICRImage Check Reader

SWC COMMAND – MISCELLANEOUS FUNCTION PARAMETERS

The SWC command controls miscellaneous parameters, shown in Table 2-5 and described below.

Table 2-5. SWC Command – Miscellaneous Parameters

BITS FUNCTION

7 6 5 4 3 2 1 0

0 CMC-7 Character Set: No 1 CMC-7 Character Set: Yes 0 0 Invalid Commands: ?<CR> 0 1 Invalid Commands : No Reply (Header

Required)*

1 0 Invalid Commands: No Reply (no header

required) 1 1 Ignore all Commands 0 Active RTS: No 1 Active RTS: Yes

0 Data Header: No 1 Data Header: Yes 0 Card Data Message: Multiple 1 Card Data Message: Single 0 Compatible Replies

1 Extended Replies** 0 Send only if MICR (Compatible) 1 ‘No MICR’ Response**

*Header Required means all commands must be preceded by a GS character (Hex 1D).

**Setting these bits means the Reader may not be compatible with applications using previous MagTek MICR Products.

CMC-7 Character Set

If NO is selected, the MICR Reader will only read E13-B characters. When YES is selected, the MICR Reader will read both CMC-7 and E13-B characters (see Appendix B). However, the MICR Reader will only output raw data ("as is" on the check) for checks with CMC-7 characters.

Invalid Command Response

Invalid command response is the action the MICRImage takes upon receipt of a command it does not recognize. It can also be used to stop the MICRImage from receiving any more commands.

The first option “?<CR>” is the default. If the MICRImage receives an unrecognized command, it will return a question mark and carriage return to the host. The MICRImage will then return to an idle state and wait for further commands or check/credit card reads.

For the second option, “no reply - header required,” the MICRImage will only execute commands preceded by a GS ASCII character (hex 1D), and it will not reply to invalid

Section 2. Configuration Commands

commands. When this option is selected, all messages received without a GS header will be transmitted “as received” through the RS-232 auxiliary port. For the third option, “no reply,” the MICRImage will execute all valid commands, but it will not reply to invalid commands.

The fourth option, “ignore all commands,” causes the MICRImage to stop receiving any Host data and to ignore any further commands. Even the SA (Save) command is ignored and therefore this fourth option is only temporary. To make this option permanent or to reset it, you must use an Insta-Change check.

Active RTS

When this function is set to YES, the MICRImage will raise RTS and wait 5 seconds for CTS to become active before sending any data. If the 5 seconds expire and CTS is not active, the data message will be discarded and nothing will be sent.

Data Header

If YES is selected, a single character header precedes the data. For MICR data, the message is transmitted as follows:

‘C’[data]

For card data, the header position on the message is controlled by the Card Data Message parameter (see below). Therefore, the message may be transmitted as follows:

If Multiple Message: ‘M’[TK1]‘M’[TK2]’M’[TK3]

If Single Message: ‘M’[TK1] [TK2] [TK3]

It is important to note that the Data Header precedes the data and not the message. For example, if <STX>, <ETX> and Data Header are set to YES, a MICR data message will be transmitted as follows:

Card Data Message

This parameter determines the structure of the output message for the individual tracks when a credit card is read. If Multiple is selected, the Control Characters (see SWB, below) and Data Header (see Data Header, above) are added to each track individually. On the other hand, if Single is selected, all available tracks are lumped together into a single message. For example, if <STX>, <ETX> and Data Header are set to YES, the output message may be transmitted as follows:

MICRImage Check Reader

If Multiple Message: <STX>‘M’[TK1]<ETX><STX>‘M’[TK2]<ETX><STX>‘M’[TK3]<ETX> If Single Message: <STX>‘M’[TK1] [TK2] [TK3]<ETX>

Extended Replies

There are a number of commands in the standard MICR command set that do not provide any response when the operation is completed or with a simple '?<CR> when an error occurs. By setting this option, commands that normally provide no response will return 'OK<CR>' if the command executes successfully. For commands that respond with a '?<CR>' to report an error, the extended reply is '?xxx<CR>' where xxx is a three-digit error code. See Appendix D for a complete listing of the error codes.

‘No MICR’ Response

For applications where both MICR and non-MICR encoded documents will be scanned, setting this option will provide a 'No MICR' response when no MICR characters are detected.

SWD COMMAND – AUXILIARY PORT PARAMETERS

The SWD command, shown in Table 2-6, controls the communication parameters for the RS-232 Auxiliary Port.
