Communications in Progress
5.3.1 Data Reception
During data reception, a message similar to this will
be displayed:
In Communication
1234 56
If valid Caller Identification information is received, a
message similar to this will be displayed:
TEL:15145551212
1234 56
The DRL2E decodes all information received and
stores the information in its event buffer. When a valid
signal is received, the DRL2E sends a kissoff signal
and transmits the decoded alarm signal to the com-
puter and then to the printer through the CPM2.
Options [1D] and [1E] can be adjusted to allow the
DRL2E to compensate for weak signals or noisy tele-
phone lines; refer to “DRL2E Programmable Features”
for information on programming these options.
The DRL2E will send each message it receives to the
printer for review by the system operator. Two mes-
sages may be sent to the printer to indicate reception
problems: “Invalid Report” and “Communication Fail”.
5.3.2 Invalid Report Message
When this problem is encountered, the following
information is transmitted to the printer and the com-
puter:
Printer: L01- 0000-INVALID REPORT TIME:DATE
Computer: 0RRL[#0000 | NYNRRL]
NOTE:
The first RRL is subject to the line card
length option.The second RRL is the receiver and
line card number, both in HEX.
This output for account code “0000” indicates that
data has been received, but is not valid (for example,
there are unmatched rounds or the wrong parity). The
following is an example of faulty data received by the
DRL2E, and the printer output generated:
NOTE:
There is only 1 invalid report at the end of a
call.
5.3.3 Communication Fail
When this problem is encountered, the following
information is transmitted to the printer and the com-
puter:
Printer: L01-0000-COMMUNICATION FAIL TIME:
DATE
Computer: 0RRL[#0000 | NYCRRL]
NOTE:
The first RRL is subject to the line card
length option. The second RRLL is the receiver and
line card number, both in HEX.
This output indicates that a call was received, but no
data was detected. The call may have been a wrong
number, or the calling control panel was unable to
connect with the receiver’s handshake.
5.3.4 Caller ID
If an Invalid Report or Communication Fail occurs,
and Caller ID is enabled, the printer messages will be
similar to the following:
Fault Data: “??????10 5551212”
Fault Call: “??????40 5551212”
Note that “?” represents the missing data; “5551212”
represents the originating telephone number.
5.3.5 Stopping Data Reception Manually
To cancel communications between the DRL2E line
card and the calling control panel, press the [CANCEL]
button. Pressing the [CANCEL] button will hang up the
line. This feature can be used to hang up on a control
panel that is repeatedly sending alarms.
