Option 13: Erase Alarm Message Buffer
NOTE:
Under normal operating conditions, the
buffer should not be erased.
Option [13] is used to erase the CPM2 alarm mes-
sage buffer. Press the [ACK] button when the “13:
Erase Memory” message is displayed; this message
will be displayed:
Erase all MEMORY
ent=Y bs=N esc=X
Press the [Backspace] or [Escape] buttons to cancel
this option without erasing the CPM2 buffer. To erase
the buffer, press the [Enter] button. When the [Enter]
button is pressed, this message will be displayed:
Are You Sure?
ent=Y bs=N esc=X
Again, press the [Backspace] or [Escape] buttons to
cancel this option without erasing the CPM2 buffer. To
erase the buffer, press the [Enter] button. When the
[Enter] button is pressed, all printer and computer
messages will be erased. Ensure that a printed record
of the alarm messages is made before erasing the
buffer.
Option 14: Mute Buzzer
A buzzer will sound when the CPM2 receives an alarm
and is unable to forward the alarm message to COM1.
The buzzer can be silenced by programming Option
[14] as “1.” Press the [ACK] button when the “14:
Mute Buzzer” message is displayed; this message will
be displayed:
Mute Buzzer: 1/0
0 Change to:X
When programmed as “1,” the buzzer will not sound
when an alarm is received and cannot be forwarded
to COM1. When programmed as “0,” the buzzer will
sound when an alarm is received and cannot be for-
warded to COM1. The default setting is “0.”
NOTE:
Option 14 will have no effect on the buzzer
if the UL Receiver Option is enabled.
Option 15: Display Last Message
When an alarm is received, the alarm message is dis-
played on the screen until the message is forwarded
to the computer and printer. When the message is
sent to the computer and printer, the Standby mode
message will be displayed. The most recent alarm
message may be retained on the screen until the next
alarm message is received. To retain the most recent
alarm message, program Option [15] as “1”. Press
the [ACK] button when the “15: Keep Lst Msg” mes-
sage is displayed; this message will be displayed:
Keep Lst Msg:1/0
0 Change to:X
To have the Standby mode message displayed after an
alarm is received and sent to the computer or printer,
program Option [15] as “0”. The default setting is “0”.
When “0” or “1” has been entered, press the [Enter]
key.
Option 16: ComPort Diagnostics
The CPM2 features a Diagnostics mode that allows
the operator to view all data being communicated
through COM1 (or COM2) on the display screen. To
use this feature, press the [ACK] button when the “16:
Debug ComPort” message is displayed; this message
will be displayed:
Debug ComPort1,2
0 Change to:x
Enter “1” and press the [Enter] button to enable the
Diagnostics feature on Com1 (or “2” for Com2). All
data being sent through COM1 will now be displayed
on the screen. A typical transmission is shown here:
1RRL AAAAsX
YY N 06
N represents the number of times the CPM2 tries to
re-send the message to COM1; this value should be
“1” during normal communication.
[06] represents the Acknowledge received from
COM1 To disable the diagnostics feature, program
Option 16 as “0”. The Diagnostics mode should only
be enabled to test and review the information being
sent to COM1; the Diagnostics feature should be dis-
abled during normal receiver operation.
Option 17: Test 9V/12V Battery
Some earlier CPM2 units provide 9V battery for mem-
ory storage while present CPM2 units use different
technology for this purpose. If the unit uses 9V bat-
tery , the battery voltage should be supervised by
enabling this option. Press [ACK] button when the
“17:Test 9V/12v .” message is displayed; the following
message will be displayed:
9V/12V Batt: 0-3
2 Change to:x
0
Do not supervise the 12V and 9V batteries
1
Supervise 9V only
2
Supervise 12V only
3
Supervise both batteries
Option 18: Line Card Diagnostics
The CPM2 features a Diagnostics mode that allows
the operator to view all data being communicated
between the CPM2 and the line cards. To enable this
feature, press the [ACK] button when the “18: Debug
LnCard#” message is displayed.
Enter a hexadecimal number from “1” through “E” to
monitor line card 01 through 14, or enter “FF” to
monitor all line cards connected to the CPM2.
Standby communications between the line card and
the CPM2 will be displayed with messages similar to
this:
01
FE
• 01 represents the line card number
• FE represents the response from line number 1 to
the normal CPM2 alarm messages transmitted by
the line cards will be displayed with messages sim-
ilar to this:
L01-1234-C01
