TABLE 1.7-1. *C Mode Entries and Codes
Key Display
Entry ID: Data Description
*C 12:0000 Enter current password.
If correct, then advance,
else exit *C Mode. 12:00
indicates *C Mode is not
in PROMs. If security is
disabled, *C advances
directly to window 1.
A 01:00 Window 1, enter
command:
00 = disable security and
advance to window
2; subsequent *0 or
*6 enables security.
01 = security remains
enabled, but it
advances to window
2 and allows entry of
a new password.
A 02:XXXX Set new password
(XXXX is current
password).
A Returns to window 1.
Entering 0000 disables
security (window 1 must
be set to 0).
1.8 *D MODE -- SAVE OR LOAD
PROGRAM
The *D Mode allows the user's program
information in the *1, *2, *3, *4, *A, *C (if OSX-
0), and *B Modes to be output to or loaded from
printer/computer (ASCII) or SM192/716 Storage
Module. Table execution and on-line printer
outputs are suspended while in the *D Mode.
When *D is keyed, the CR7 will display "13:00".
TABLE 1.8-1. *D Mode Commands
Command Description
1 Save ASCII Program
2 Load ASCII Program
71 Save/Load/Clear Program
from Storage Module
A command is entered by keying the command
number and A. When Command 1, 2, or 71 is
entered, the command number is displayed in
the ID field. The user must then key in a baud
rate code for command 1 or 2 or the command
code for the Storage Module (Table 1.8-2).
After the code is keyed in, key A to execute the
command. After a command is executed,
"13:0000" is displayed; *D must be entered
again before another command can be given.
If the CR7 program has not been compiled
when a command to save the program is
entered, it will be compiled before the command
is executed.
