System Setup
The programmer receives CRC commands and sends responses to the
host computer through an RS-232C port using a 25-pin D connector in
two possible configurations: either DTE or DCE. Only the Handler port
supports CRC operation.
The pin designations for the Handler port are shown in the “More About
Cables” section of Chapter 2. Included in that section is a table of pin
definitions which explain the function of each pin for the two serial port
configurations.
To ensure correct operation of the Handler port with the host computer,
set the parameters for the Handler port according to the host computer
requirements.
Entering CRC Mode
Follow the steps below to enter CRC mode at powerup.
AutoSite enters CRC mode during powerup if it detects equipment
connected to the Handler port.
Note: CRC operations must be run from the Handler port; AutoSite does not
support powerup CRC on the Auxiliary port.
To ensure correct operation of the Handler port with the host computer,
set the parameters for the Handler port according to the host computer
requirements.
Halting CRC
Operations
To halt any command or any ongoing CRC operation, use one of the
following commands from the Handler port. Neither of the following two
commands requires that you press
↵
. Both commands are immediate and
both terminate any preceding command operation.
ASCII
Command Hex Code Description
E
SC
1B Causes AutoSite to unconditionally halt
any operation except a binary transfer.
B
REAK
n/a Causes AutoSite to unconditionally halt
any operation in progress. This includes
all data communications transfers. The
data line must be held in the spacing
condition for 110 ms to 700 ms.

CRC Default Settings
When CRC mode is entered, certain defaults are set prior to Autosite’s
accepting any commands. The default settings are outlined below:
If you exit remote mode using the

CRC Commands
CRC commands are a set of simplified commands for AutoSite. The
commands are designed to be received from a controlling computer.
Because the commands are so simplified, they can be cryptic.
CRC Command
Summary
You send CRC commands to AutoSite by typing the command and then
pressing the
↵
key. When AutoSite receives a CRC command, the
command is executed and a response is sent back, followed by a carriage
return. If the response is an F, an error occurred. If the response is a ?,
AutoSite did not understand the command. If the response is a >, the
normal CRC prompt, the command executed properly. Some commands
respond with both a value and the prompt. For example, AutoSite 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
I
,
O
, and
C
commands perform any
data transfer prior to sending the response.
Each command in the CRC command set is summarized in the following
tables. For a more detailed explanation of CRC commands, refer to the
“UniSystem Computer Remote Control” Application Note available from
Customer Support. 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, AutoSite recognizes only uppercase characters.
Except where noted, the commands use the following notation
conventions:
• lowercase alphabetic characters indicate arguments that must be
specified
•
h
represents a hexadecimal digit.
•
n
represents a decimal digit.
•
xxx...xxxx
represents a string of characters.
For example,
nn02
indicates that you may precede the
02
command with
two decimal digits.
