CRC Default Settings

When CRC mode is entered, certain defaults are set prior to accepting any

commands. The default settings are outlined below:

If you exit remote mode using the

command, the 2500 programming

electronics' parameters are set to the values they held

before

you entered

remote mode. If you exit using

TRL

, the 2500 programming

electronics' parameters remain at their current values.

Programming

Electronics CRC

Commands

CRC commands are a set of simplified commands for the 2500

programming electronics. The commands are designed to be received

from a controlling computer. Because the commands are so simplified,

they can be cryptic.

You send CRC commands to the 2500 programming electronics by typing

the command and then pressing

↵

. When the 2500 programming

electronics receive a CRC command, the command is executed and a

response character with a carriage return is sent back. Three responses

from the 2500 are possible:

Indicates that an error occurred. The “X” CRC command prompts the

2500 to return a specific error code (listed later in this Appendix) that

describes the error.

Indicates that the 2500 programming electronics did not understand

the command received. The command string was not formatted as

described in this section or the command was sent using lowercase

characters.

Indicates that the last command was received, executed and

completed without any errors.

Some commands respond with both a value and the prompt. For

example, the 2500 might return

00284295>

when you send the Calculate

Sumcheck command. In this case, the

00284295

is the sumcheck and the

indicates that the command executed properly. The

and

commands perform any data transfer prior to sending the response.

Each command in the CRC command set is summarized in the following

tables and described in detail in an Application Note titled “UniSystem

Computer Remote Control.” Contact Data I/O Customer Support (as

listed in the Preface) to order this document.

The command tables are broken up into

standard

and

extended

CRC

commands. Standard CRC commands are commonly used commands,

such as load, program, and verify. Extended CRC commands are more

specific device-related commands, such as Set Security Fuse, Fill Fuse

Map, and Set Vector Test Options.

Note: While in CRC mode, the 2500 programming electronics recognize only

uppercase characters.

Lowercase alphabetic characters indicate arguments that must be

specified. Except where noted, the commands use the following notation

conventions:

•

represents a hexadecimal digit

•

represents a decimal digit

•

xxx...xxxx

represents a string of characters

All alphabetic characters used in arguments must be sent to the 2500 in

uppercase.

For example,

02]

indicates that you may precede the 02] command

with two decimal digits.
