8.6.1 [A] Send Computer Messages to Printer
This mode is used to send the computer messages
from the buffer to the printer. When the [A] key is
pressed, this message will be displayed:
Dump COM Msg->PRT
Lcard#:FF Ent:EXE
Enter a hexadecimal number to print the following:
Enter... to print

Example: If “0” is entered, the following will be
printed:
Dump Computer Alarm Buffer

1011 ...... 0000 . A .. 01 12:38:22 - 12/10 106
NOTE:
“106” indicates the message was sent to the
computer once and the computer has responded
correctly with an [06] acknowledge.
8.6.2 [B] Operator Log-On
Different operators may “log on” to the system by
entering this mode. When an operator logs on, a mes-
sage similar to this one will be printed: “Operator on
duty S.G. 11:03-21/12/92”; the operator’s initials (if
programmed) and the time and date will be printed. If
the Star 8340 printer is being used, this message will
be printed in red.
To log on, press the [B] key, and then enter a 4-digit
password. If a valid password is entered, a log-on
message will be printed. If an invalid password is
entered, the CPM2 will sound a tone to indicate that
the code was entered incorrectly. Refer to CPM2
Option [02] for information on programming operator
passwords and initials.
8.6.3 [C] System Command Mode
The System Command mode is used to send com-
mands to the line cards through the CPM2. To enter
this mode, press [C] and then enter an Operator
password. When the password is entered, this mes-
sage will be displayed:

• LCard: Enter a 2-digit hexadecimal number from 01
to 0E to indicate which line card is to be affected.
• Comd: Enter one of the line card Commands
described in the DRL2E line card Menu mode sec-
tion of this manual
• Op: and Cd: “Op” and “Cd” are used to indicate
parameters that may be required within certain
commands. For example, when using the F7 line
card programming command “Op” and “Cd” are
used to indicate the Option number and the new
code programmed for that option.
• Sc: “Sc” is used with SCADA applications. Enter
digits using the keypad; when a digit is entered, the
cursor will move one character to the right. Press
the [Backspace] button to delete the character
presently indicated by the cursor and move the
cursor 1 character to the left. When a command
has been entered, press the [Escape] button to
send the command to the line card. If more than
one command is to be sent, press the [ACK] button
to send the command presently displayed on the
screen. Another command may now be entered.
8.6.4 [D] Send Printer Messages to the Printer
