6.2.1 F7 Line Card options Programming
Line Card-F7-Option-Code
The F7 Options Programming command is used to
change various operating parameters for the line card:
reporting codes, the line card number, buzzer opera-
tion and other features. Functions can also be changed
using the F7 command.
Refer to the example illustrated in 'Entering Com-
mands' in the 'DRL2E Programming Commands' sec-
tion of this manual.
Refer to the DRL2E Reference Sheets in the back of
this manual; be sure to record any programming
changes on these sheets.
NOTE:
Options are programmed with 2 hexadecimal
.
6.3
Static Options: [00] - [2F]
Option [00]: Reserved
Option [01]: Line Card Number - Default [00]
The line card Number provides a virtual identification
code for each DRL2E module. Hexadecimal numbers
'01' to 'FE' can be programmed in Option [01] to iden-
tify line cards.
Option [02]: Line Card Number Length - Default [0E]
This option is used to determine how many digits from
the line card number will be sent to the output. You
also have the option of displaying the number in hex or
decimal. Program Option 02 with one of the following:
01 Send only one Hex digit to the printer or computer
output (if you have a 2-digit line card number only
the last digit will be sent to the output)
02 Send 2 Hex digit line card number to the output
03 Send 3 Hex digit line card number to the output
(leading Zeros will be inserted prior to the line card
number)
0A Send 3-digit line card number as entered (no con-
version).
0D Send 3-digit line card number in decimal (conver-
sion from decimal to hex decimal
0E Send a 1-character line number 1-9, A-Z
Option [03]: Internal messages RS-232 - Default [01]
When this option is programmed as ‘00’, the DRL2E will
output its internal messages in the following format:
SRRL[#AAAA|Nxxyy]
If it is programmed as ’01’ internal messages will be
output as
0RRL[#AAAA|Nxxyy]
Where S, 0 (zero) = Protocol number
RR = Receiver number
L = Line number
AAAA = Account code, always 0000
Nxxyy = SIA event
Option [04]: 2-Way Audio Activation Time - Default
[00]*
Option [04] determines how long, in 10-second incre-
ments, the 2-way audio function will be active once it
is initiated. At the end of this time, the line card will
hang up the line. Program a value from "01" to "FF" for
10 seconds to 2550 seconds. Three (3) minutes is the
recommended length of time for the 2-way audio acti-
vation time. To disable the 2-way audio feature, pro-
gram Option [04] as "00".
NOTES:
Enabling 2-way audio will affect NFPA 72
system loading requirements. Refer to Par. 4-5.3.2.2.2
of NFPA 72 for details.
If the alarm panel sends a listen-in code activation
request and audio is enabled for this format (Option
[7F]), the receiver will remain in two-way voice for a
period of 60 seconds even if the activation time is
not programmed.
* Use only with Model SG-MLR2E CE (not UL
listed).
Option [05]: Pre-H.S. Duration - Default [0A]
When the line card seizes the line, it will wait the time
programmed at Option [05]; then send the first hand-
shake. The value programmed (hex) at this location will
be multiplied by 100 ms. [e.g., 100 ms., 200 ms.] The
default is 0A, for 1000ms (100ms x default value).
The minimum time is 1 second. If the option is pro-
grammed with any value lower than 0A, the line card
will use a 1 second delay.
Options [06] to [0C]: Reserved
Option [0D]: Ring Select - Default [00]
Enables or disables the double ring detection. If pro-
grammed as 00, the line card will detect single ring. If
programmed as 01, the line card will detect the double
ring.
Option [0E-10]: Reserved
Option [11]: Hook-flash Enable/Disable - Default
[00]
Enables or disables ability to hookflash the phone line
and determines its duration in increments of 10 ms.
If programmed as 00, the option is disabled. If set to
anything else, you multiply the decimal equivalent of
the hex value by 10 ms and that is the duration. For
example, if hookflash time of 500 ms is wanted, pro-
gram Option 2A to 32 Hex.
Option [12]: Caller Source ID Option - Default [00]
Option [12] allows the line card to receive Caller Identi-
fication data or DNIS that is transmitted after the first
ring on the telephone line. The appropriate service must
be available and requested from the Telephone Com-
pany for this feature to be operational.
