Hex Label Format

The Hex Label format has been developed to encode data files in ASCII

format to transfer between the Remote RS232C port on the 2500 and the

attached computer system.

Label Record

Content

Label records appear as character strings consisting of the following four

fields: identifying record type, record length, data, and checksum. Each

byte of binary data is encoded as a 2-character hexadecimal number; the

first character represents the four high-order bits, and the second

represents the four low-order bits of the byte. The four fields are

described below.

Each record can be terminated with a CR/LF/NULL. Accuracy of

transmission is ensured by the record length (byte count) and checksum

fields.

Label Record Types

Eight types of label records facilitate information exchange between the

2500 and other computer systems. Two more have been identified for

future requirements. These records are described below.

The header record for each block of label records. The data field can

contain any descriptive information identifying the following block of

label records.

A record containing labeling information. The data field may contain up

to 8 lines of 18 characters specifying the contents of the label. A 0D hex is

used as a delimiter between lines. A copyright character can be selected

by a 1F hex.

Field

No. of ASCII

Characters Description

Record Type 2 Label Record Type Q0, Q1...Q9.

Record Length 2 The count of the character pairs

in the record, excluding the

record type and record length.

Data 0-2

From 0 to

bytes of data.

Checksum 2 The least significant byte of the

one’s complement of the sum of

the values, represented by the

pairs of characters making up the

record length and the data fields.

This record contains the index number in hex of the type of device to be

handled. The following device types and their index numbers are

available for handling:

To select a 28-pin PLCC device, send the following Q2 record:

Q20202FB

If the index number is 16, the record converts 16 decimal to 10 hex and

looks like this:

Q20210ED

The remote computer can download the most current device list

contained in the 2500 by sending an @15 command.

If you need to handle a device type not currently defined, you can use a

Q3 record in place of the Q2 record to define the device type. A Q2 or Q3

record must be present or an error is displayed.

This record type is used instead of a Q2 record to define a custom device

length. It contains a 4-digit field defining the device length in thousands

of an inch, represented in hex.

The length of a device is defined as the distance between the outermost

extensions of the device (pins included) in the direction of travel through

the 2500’s track. The device length must be represented as an integer

before it is converted to a hex value.

To define a device with a length of .491 inches long:

1. Convert 0.491 into an integer by dividing it by 0.001. The result is 491.

2. Convert 491 (decimal) to 01EB (hex).

3. Complete record =

Q30301EB10

A Q2 or Q3 record must be present or an error message is displayed.

This record contains print density information. It is allowed one data byte

and is defined as follows:

To select a print density of 26 CPI for the dot matrix printer, the record

would be

Q60201FC

. If this record is not received, the 12 CPI print

density is assumed.

This record defines the device pin 1 orientation at three locations on the

2500:

• Out of the input tube.

• The label application area.

• Into the output (receiving) tube.

This information allows the 2500 to rotate the device correctly before it

inserts it into the programming station, labels it, and inserts it into an

output (receiving) tube.

The location of pin 1 with respect to the 2500 and the direction of travel, is

represented as a number from 0 to 3 displayed in the diagram below:

All three pin locations are represented in one-binary byte that is

converted to hex. An example of the rotation byte is illustrated below.
