Utility Commands - Data I/O 298 Manual

B.8.2 UTILITY COMMANDS
The following are Utility Commands:
KEYBOARD FORMAT Command
Operation:
Code:
Syntax:
KEYBOARD FORMAT
KF
(>)
[Kl [F] [Address Base] [/] [Data Base]
[CR]
Explanation: The KF command sets the address and data
bases the operator will use in communicating
addresses and data. These number bases may
differ; for example, hexadecimal addresses
and binary data may be displayed together.
Default Value - hexadecimal.
Bases: 0 = hexadecimal
1
decimal
2
octal
3 binary
CONFIGURATION NUMBER Command
Operation: CONFIGURATION NUMBER
Code: CN
Syntax:
(>)
[Cl [N] [CR]
Explanation: This command displays the configuration
number which identifies the software resident
in the 298.
NIBBLE MODE Command
Operation: NiBBLE MODE
Code: NM
Syntax:
(>)
[N] [M] [CR]
Explanation: This command sets a 4-bit word size to
override 8-bit programming Paks. Default
Value - programming electronics word size.
NOTE
The word size in effect does not change
upon entering or exiting remote control.
BYTE MODE Command
Operation: BYTE MODE
Code: BM
Syntax:
(>)
[Bl [Ml [CR]
Explanation: This command nullifies the Nibble Mode
command, allowing the programming Pak
word size to take effect.
SIZE MEMORY Command
Operation: SiZE MEMORY
Code: SM
Syntax: (>)
[S] [Ml [CR]
Explanation: This command causes the terminal to display
the beginning and ending addresses in RAM,
added to the address offset in effect. The
beginning address value is the address-offset.
The ending RAM address is the beginning
address plus the available RAM size.
NOTE
For the 298 version with 64k bytes RAM:
If the virtual address offset (see the
~VM" command) is greater than zero the
ending address displayed will not show
the most significant bit(s). This is
because only the 16 lowest order binary
bits of the address are shown on the
display. The operator must add the most
significant bits which will be equal to "1"
binary to derive the ending address.
SELECT EXTERNAL FUNCTION Command
Operation: SELECT EXTERNAL FUNCTION
Code: SF
Syntax:
(>
l [S] [F] [Select Code] [CR]
Explanation: Some Select Codes are associated with the
programming Pak, and can only be accessed
when that Pak is installed in the programmer.
To access those Select Code functions in
terminal remote control, the Select Code is
entered after SF.
SUMCHECK Command
Operation: SUMCHECK
Code: SC
Syntax:
(>)
[S] [C] [CR]
Explanation: This command instructs the programmer to
compute the sumcheck of all RAM data and
to display it at the terminal. For example, the
terminal will display "SUM= 06FE."
NOTE
If
data in the RAM has been recently
changed the operator should wait at least
three seconds before issuing this
command to insure valid results.
NO OPERATION Command
Operation:
Code:
Syntax:
