INTRODUCTION
The MLR2-E is a Multi-Line, Multi-Format Digital Receiver for
commercial fire and burglary. The basic unit consists of up
to 30 individual line cards (DRL2E) connected to a CPM2.
The MLR2-E can decode a variety of popular and widely
used communication formats. Refer to Appendix A, DRL2E
Communication Formats for a list of the available communication
protocols.
The MLR2-E’s real-time clock and calendar stamps all
information received with the time and date, and all information
may be printed and/or forwarded to a computer. To ensure
security, adjustment of the clock, calendar and other
programming is password-protected.
CPM2
The CPM2 Central Processing Module oversees operation
of the line cards. Along with its built-in keypad and LCD
message screen, the CPM2 features one parallel printer,
and two COM Ports.
DRL2E
Each DRL2E Module can monitor two telephone lines. The
Line Card module is equipped with a 256-event nonvolatile
memory buffer to record events and corresponding telephone
numbers. Caller Source capability is built-in and telephone
numbers can be printed out, sent to automation and stored
in memory. Events and information stored in memory can be
printed at any time. Each line card also features flash EPROM
uploads through the Debug port for software upgrades or
options programming.
SUPERVISION
The standby battery voltage and connections are supervised.
The Line Cards are also continuously supervised to ensure
uninterrupted communication with the CPM2. Any trouble
conditions are reported on the LCD screens and sent to the
printer and the computer.
The DRL2E Line Card Module also verifies communications with
the CPM2. In the event of a malfunction, the operator will be
advised with a visual indication and the Line Cards will continue
to function. Each line card will continue to receive information.
The printer is supervised for loss of power, off-line, paper out
and other trouble conditions. The communication link to the
computer through the RS-232 port is monitored by the
supervisory “heartbeat” test transmissions.
COMPATIBILITY
Central station automation software packages such as:
• M.A.S. • DICE • SIMSII • S.I.S. • GENESIS • MICROKEY
support the MLR2-E Sur-Gard interface. Compatibility with the
automation software in a system used at a central station is
intended to be handled under a separate UL 1981 software
and/or site certification evaluation.
CPM2 OUTPUTS/INPUTS
The CPM2 features three switched-negative outputs. One output
labeled “OPTION” has a corresponding LED on the CPM2
front panel; the factory default programming slowly flashes
the OPTION LED when the “OPTION” output is activated.
Switched negative outputs are also provided for the
Acknowledge and Trouble LEDs.

VIRTUAL RECEIVER ARCHITECTURE
The most novel feature of the DRL2E is the ability to use the
telephone company information delivered as DNIS (Dialed
Number Information Service) or Caller ID. This allows the
Sur-Gard Format Expert System to handle on the fly each
received call. With this feature, dedicated line pool hardware
is eliminated. Instead, the DNIS or Caller ID information allows
dynamic options that set up virtual line pools to identify security
formats and extend account numbers.
Standard DNIS is supported up to 10 digits. Each dialed
number should be assigned to a virtual receiver. Multiple
Caller ID numbers can be assigned to a single virtual receiver.
Each dialed number would formerly have been a line pool on
conventional line cards.
NUMBER OF LINE CARDS SUPPORTED
The system will support a maximum of 15 line cards concurrently
connected.

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:[phone]
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 computer 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 telephone 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 messages may be
sent to the printer to indicate reception problems: the “Invalid
Report”and “Communication Fail”.
FAULT DATA MESSAGE
When this problem is encountered, the following information
is transmitted to the printer and the computer:
Printer: L01- 0000-INVALID REPORT TIME:DATE
Computer: 0RRL[#0000 | NYNRRLL]
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 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:
Round Data Received Printer Output
1st 123456 [No printout]
2nd 123446 ?1234?56 Invalid Report
?1234?46 Invalid Report
3rd 123356 ?1233?56 Invalid Report
4th 123456 ?1234?56 Invalid Report
5th 123346 ?1233?46 Invalid Report
?????10 Invalid Report
NOTE: There is only 1 invalid report at the end of a call.
FAULT CALL
When this problem is encountered, the following information
is transmitted to the printer and the computer:
Printer: L01- 0000-COMMUNICATION FAIL TIME:DATE
Computer: 0RRL[#0000 | NYCRRLL]
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.
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.
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.

11
PROFILES
The DRL2E will load unique “profiles”in order to effectively
communicate with control panels. A profile is a set of pre-
programmed line card options unique for a particular “calling id
number”or DNIS number. The “Calling id”or “DNIS”will point to
a particular profile, which will then be loaded into the line card at
the beginning of each call.
Each DRL2E can have a maximum of 64 profiles. To change the
options for a particular profile, utility software is provided. This
software will allow the user /operator to edit the profiles.
STATIC OPTIONS
Option [01]: Line Card Number
The Line Card Number provides a virtual identification code
for each DRL2E module. Hexadecimal numbers “01”to “1E”
can be programmed in Option [01] to identify Line Cards.
[Default is 0D or 0E]
Option [02]: Line Card Number Length
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 2 digits receiver number in decimal. 3 digits
line number in decimal.
0D Send 2 digits receiver number as programmed. Send
3 digits line card number in decimal
0E Send 2 digits receiver number in Hex. Send 1 digit
line card number as follows:
Line Card #Line Card #
Line Card #Line Card #
Line Card # SendSend
SendSend
Send
1..F 1..F
10..1E G..U
NOTE:When using the DRL2E, the Line Card Number Length
option should always correspond to the number of DNIS
digits being received.
For example, if 5 digits are being received then the Line
Card Number Length Option should be programmed to 3
such that 1RRLLL would be overwritten by the 5 digits of
DNIS to become 1ddddd. [Default is 0E]
Option [03]: DSC SIA Audio
This option determines if the line card will initiate two-way
audio on a bad SIA signal. Normally, if the panel sends an
SIA signal, and is not ACKed, the panel and receiver will
hang-up. If a panel is being used to send life alarms (e.g. -
hospital monitoring, etc.), two-way audio is always wanted.
With this option turned on, although the incoming data is
bad, two-way audio will be initiated, allowing the operator to
hear everything on the panel side. [Default is 01]
Option [04]: 2-Way Audio Activation Time
Option [04] determines how long, in 10-second increments,
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 to 2550 seconds.
Three minutes (set option 04 to 12) is the recommended
length of time for the 2-Way Audio Activation time.
To disable the 2-Way Audio feature, program Option [04]
as “00”. [Default is 00]
Option [05]: Pre-Handshake Delay
When the line card seizes the line, it will wait the time programmed
at option [05], then send the first handshake.
The time programmed (hex) at this location will be multiplied
by 100 ms –e.g., 100 ms, 200 ms etc.
The default setting is 0A, for 1 second.
NOTE: If DNIS is used, this time will not start until DNIS
is received.
[Default is 00]
Option [0E]: Line Detection Reports
The Line Card will perform periodic telephone line tests. When
Option [0E] is enabled, if the line is faulty, a warning LED will
be displayed on the Line Card front panel and an alarm will
be sent to the computer and the printer. When option [0E] is
disabled, no alarm will be transmitted. [Default is 01]
Option [0F]: Mute Buzzer Option
Operation of the line card’s buzzer may be programmed as follows:
00 Buzzer sounds for line fault, CPM2 error, or if an
alarm occurs during a CPM2 error
01 Buzzer does not sound for any event
02 Buzzer sounds for audio, line fault, CPM2 error, or if
an alarm occurs during a CPM2 error
03 Buzzer sounds for all status change conditions
[Default is 00]
Option [10]: Keep Last Message On
To have the last alarm message retained on the DRL2E display,
enable this option with a setting of 01.
Option [11]: Hook-flash Enable/Disable
Enables or disables ability to hook-flash the phone lines 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
10ms and that is the duration.
For example, if a hook-flash time of 500 ms is wanted, program
option [11] to 32 hex. 500 ms/10=50, 50 Dec=32 hex.
[Default is 00]
Option [12]: Caller Source Selection
Option [12] allows the Line Card to receive Caller ID 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 Company for this feature to be operational.

On-line duration delay is built in to control runaway dialers.
A duration delay from 01 to 99 minutes can be programmed.
The receiver starts timing when it picks up the line and, when
the delay expires, the receiver will hang up the call even if
the dialer continues to send data. If the duration delay is
programmed as 00, this feature will be disabled.
[Default is 00]
DEFAULT DYNAMIC OPTIONS
The DRL2E uses a unique Sur-Gard communication format
to transmit data through the CPM2 to the central station
computer. Event codes corresponding to alarm codes in 10
to 40 Baud formats and DTMF 4/1 to 4/3 formats are used
in this unique format to enable the computer software to
determine alarm types.
Options [30] - [3F]: 3/1, 4/1 Format Event Codes
The DRL2E will use the last digit of data received in 3/1 and
4/1 formats to determine the computer event code. The event
code will then be transmitted to the central station computer.
Refer to the DRL2E Decoding Library for the complete set of
event codes used by the DRL2E.
In Sections [30] through [3F], program ASCII codes according to
the Decoding Library. Values other than 20-7F (ASCII) will not be
accepted. Note that the old value programmed in each Option
will not be changed until a command with valid data is received.
Default settings are as below:
•30-38: 41 •3A: 41 •3C: 43 •3E: 52
•39: 52 •3B: 4F •3D: 5C •3F: 54

13
Options [40] - [4F]: 4/2 Format Event Codes Selection
The DRL2E will use the first digit following the account code
in 4/2, 3/1 extended, 4/1 extended, or 3/2 formats to determine
the computer event code. The event code will then be
transmitted to the central station computer. Refer to the “DRL2E
Decoding Library”for the complete set of event codes used
by the DRL2E.
In Sections [40] through [4F], program ASCII codes according to
the Decoding Library. Values other than 20-7F (ASCII) will not be
accepted. Note that the old value programmed in each Option
will not be changed until a command with valid data is received.
Default settings are as below:
•40-48: 41 •4A: 41 •4C: 43 •4E: 52
•49: 52 •4B: 4F •4D: 5C •4F: 54
Options [50] - [5F]: 4/3 Format Event Codes Selection
The DRL2E will use the fifth digit of data received in 4/3 and 4/
2 extended formats to determine the message and event code.
The event code will then be transmitted to the central station
computer. Refer to the “DRL2E Decoding Library”for the complete
set of messages and event codes used by the DRL2E.
In Sections [50] through [5F], program ASCII codes according to
the Decoding Library. Values other than 20-7F (ASCII) will not be
accepted. Note that the old value programmed in each Option

•53: 41 •57: 41 •5B: 43 •5F: 5C
Option [60]-[6F]: See APPENDIX D
Option [70]: Automation Common Event Code
Some central station software packages are unable to process
the alarm using the event codes listed in the DRL2E Decoding
Library. Where a central station monitors thousands of accounts
belonging to different companies, the same reporting codes
may have different meanings depending on the company.
Because of this, the individual event codes in Options [30]
through [5F] cannot accurately represent the alarm condition.
To overcome this, Option [70] may be programmed as follows:
Program Operation
00 Use Individual Event Codes to computer
20, 30-39, 41-5A Use Common Event Codes (space, 0-9, A-Z)
When using Common Event Codes, it is recommended that
either hexadecimal code “5A”(ASCII “Z”) or hexadecimal
code “41”(ASCII “A”) be used.
The “Space”character (Hex 20) can be used as the common
event code with certain automation software packages to
avoid account code database changes when switching over
from other brand receivers to the Sur-Gard receiver.
Note that Option [70] is ignored when using Modem formats,
Contact-ID, ACRON, FBI Super Fast, BFSK, ADEMCO Super
Fast and SK FSK1, 2 formats. [Default is 00]

Option [80]: Kissoff to Hang-up Time
This option determines the delay between Kissoff and the
release of the line.
The hex value programmed at this location will be converted
to decimal and then multiplied by 100 milliseconds to generate
the delay.
For example:
Option 80 = 0A hex = 10 decimal * 100 ms = 1000 ms = 1
second delay.
Option 80 = 28 hex = 40 decimal * 100 ms = 4000 ms = 4
second delay. [Default is 1E]
Options [81] through [88]: Handshake Selection
The DRL2E is a multi-format receiver capable of sending
several handshakes to a dialer. Often it is important which
handshake is sent first. Program Options [81] through [88]
according to your applications.
Handshake Options
00 No handshake
0B Modem II handshake
0C SIA FSK handshake
0E Modem IIE, Modem IIIa2and ITI handshake
0F DMP handshake
1D Single Dual tone handshake
2D Double Dual tone handshake
FC Full duplex SIA FSK
All other frequencies can be used by programming the first
two digits. For example:
23 = 2300 Hz, 18 = 1800 Hz, 14 = 1400 Hz, 10 = 1000 Hz
Default settings are as below:
•81: 14 •83: 2D •85: 0E •87: 00
•82: 23 •84: 0C •86: 0B •88: 00
Note: For Westec formats the Handshake and Kiss-off
duration time must be set to 600ms.
Option [89] to [90]: Handshake and Kissoff Duration
Some control panels may require different handshake duration.
Each unit has increments of 100 ms, from 100 ms to a maximum
of 6.3 sec. Program options 89 to 90 to the desired duration
respective to the corresponding handshake options 81-88.
00 1 sec (default)
01 100 ms
02 200 ms
03 300 ms
04 400 ms
05 500 ms
06 600 ms
07 700 ms
08 800 ms
09 900 ms
0A 1 sec
0B 1.1 sec
0C 1.2 sec
…
3F 6.3 ms
NOTE: These options will only affect steady tone
handshakes.
[Default is 00]
Option [91]: Inter Handshake Duration
The DRL2E Line Card will usually wait for signals from the
control panels for 4 seconds before sending the next
handshake, if there are no signals received. In certain
applications, control panels can not wait long enough to get
their own handshake, especially if the handshake is
programmed as the fifth or later handshake.
Program Option [91] with one of the following:
00 4 second interval (default)
01 1 second interval (default)
02 2 second interval (default)
03 3 second interval (default) [Default is 00]
Option [95]: 5 digits pulse
The DRL2E cannot distinguish between 4/1, 3/2 and 3/1 with
checksum because all of them contain a total of 5 digits.
Therefore, this option must be programmed to inform the
DRL2E which of the 3 formats may be used.
00 select 4/1 format (default)
01 select 3/2 format (default)
02 select 3/1 with checksum format.
NOTE: The printer messages for the 3-2 format are the
same as those used for the 4/2 format.
[Default is 00]
Option [96]: 4/1 Extended Format
Program Option [96] as “01”to combine 2 round pairs of 4/
1 extended format into 4/2 output for reporting to the computer
and the printer.
For example, with Option [96] enabled, the security control
panel may transmit the following information:
1234 3
1234 3
3333 1
3333 1
The DRL2E will interpret this information as: 1234 31
This format is not recommended as it occupies the telephone
line for long periods of time. The default setting for Option
[96] is “01”; when programmed as “00,”the option is disabled.
[Default is 00]
Option [97]: 4/2 Extended Format
Program Option [97] as “01”to combine 2 round pairs of
4/2 extended format into 4/3 output for reporting to the computer
and the printer. Program one of the following:
00 4/2 Extended format data is not combined
01 The panel sends: 1234 05
1234 05
0505 16
0505 16
The DRL2E will interpret this information as 1234 516, or
the panel sends: 1234 03
1234 03
3333 01
3333 01
The DRL2E will interpret this information as 1234 301.
NOTE: The default setting for Option [97] is “00”; when
programmed as “00”, the option is disabled.
[Default is 00]

16
Option [98]: 3/1 extended format
Program Option [98] as “01”to combine 2 round pairs of 3/
1 extended format into 3/2 output for reporting to the computer
and the printer. (For M.A.S. software users, the option should
be programmed as “02”.)
For example, with Option [98] enabled, the security control
panel may transmit the following information:
123 3
123 3
333 1
333 1
The DRL2E will interpret this information as: 123 31
The default setting for Option [98] is “01”; when programmed
as “00”, the option is disabled. [Default is 00]
Option [99]: 8 digit DTMF
The Ademco 4/1 Express format may cause conflicts with the
Sur-Gard DTMF 4/3 with checksum format or FBI Superfast
without checksum. Therefore, this option must be programmed
to inform the DRL2E which of the 3 formats may be used.
00 Sur-Gard DTMF 4/3 with checksum
01 Ademco 4/1 Express
02 FBI without checksum [Default is 01]
Option [9A]: Group Arming / Disarming with User Code
Option [9A] applies to the Sur-Gard DTMF 4/3 format.
When Option [9A] is programmed as “01,”group arming/
disarming signals will be combined with the user code into
one signal which will be sent to the computer and the printer.
For example, the following information may be sent to the
computer and the printer.
•Printer:
1234-B01 CloseGrp
1234-416 Close
1234-C02 OpenGrp
1234-532 Open
•Computer:
1234 C1 16 (instead of 1234 C 01 and 1234 C 16)
1234 O2 32 (instead of 1234 O 02 and 1234 O 32)
If a user code is not received after the group opening/closing,
the message “1234 C1 FF”will be sent; “FF”indicates that
a user code was not received. [Default is 00]
Option [9B]: 4/3 Format User Conversion / 3-digit
Alarm Code
The Sur-Gard 4/3 DTMF format is made up of a 4-digit account
code, a 1-digit event code, and a 2-digit hexadecimal zone
code or user number. However, some central station software
packages use a common event code and require decimal
user codes.
Option [9B] allows the user codes to be converted from
hexadecimal to decimal to meet the needs of the central
station software. Program Option [9B] with one of the following:
00 sends the last two digits as user codes without
conversion (default).
01 converts the last 2-digit user codes to decimal as
shown here:
User Code received User Code after
conversion
00 to 99 00 to 99
B0 to B9 100 to 109
C0 to C9 110 to 119
D0 to D9 120 to 129
E0 to E9 130 to 139
F0 to F9 140 to 149
For example, if 1234 4B1 is received, 1234 C 101 will be sent
to the computer.
02 sends the last 3 digits as the zone codes with the
5th digit still used as the event code
For example, if 1234 161 is received, 1234 A 161 will be sent
to the computer.
When individual event codes are used, and 1234 401 is
received, 1234 C 401 will be transmitted to the computer.
When common event codes are used, and 1234 401 is received,
1234 Z 401 will be transmitted to the computer.
03 sends the last 3 digits as the zone codes and
convert the user codes only to decimal
NOTE: When Option [9A] Group Arming/Disarming with
User Code is programmed as “01”, the 3-digit user codes
will be combined with the group number as follows:
Code received Code sent to computer and printer
1234B01 No transmission
12344B1 1234 C1 101 [Default is 00]
Option [9D]: MODEM II RS-232
The DRL2E is able to decode the Modem II formats. The
handshake 0B needs to be programmed as one of the
handshakes of the DRL2E for the Modem II, modem IIa, or
modem IIb, and handshake 0E for Modem IIE or Modem
IIIa2. Option [9D] determines the protocol sent to the computer.
NOTE: This option will also affect the BFSK format only
if programmed as 00 or 01.
Option 9D: Modem II RS232
00: 1RRLssssssAAAAXXYYYY[DC4] (6500 protocol)
01: 6RRLssssssAAAAXXYYYY[DC4] (SG protocol)
02: Modem II to SIA protocol
03: Modem II to SIA protocol, and text is decoded
and sent to printer and computer.
NOTE: please make sure the automation software supports
settings 02 and 03 if the SIA protocol is desired.
[Default is 00]
Option [9E]: Acron RS-232
When this option is programmed as “00”, the DRL2E will
convert the Acron Super Fast format signal into 3/2 or 4/2
format (Ex: AAAAsXssYY[DC4]). If it is programmed as “01”
the Acron Super Fast will be sent to the computer as follows:
9RRLssssAAAACCCCCCCCC[DC4]

17
Where:
9 = Protocol number
RR = receiver number
L = Line number
ssss = Spaces
AAAA = Account code
CCCC = Channel 1-4
CCCC = Channel 5-8
[DC4] = Terminator
Example:
•Raw data:
1578BDDDDDDD
1578BDDDDDDD
•Printer output will be as follows:
(01-001-1578-BDDDDDDD-)
•Computer output:
(901001 1578BDDDDDDD) [Default is 01]
Option [9F]: Ademco High Speed RS-232
When this option is programmed as “00”, the DRL2E will convert
the High-Speed format signal into 4/2 format (Ex:
1RRLssssssAAAAsXssYY[DC4]). If it is programmed as “01”
the Ademco High Speed will be send to the computer as follows:
8RRLAAAAsCCCCsCCCCsC[DC4]
Where:
8 Protocol number
RR Receiver number
L Line number
AAAA Account code
s Space
CCCC Channel 1-4
s Space
CCCC Channel 5-8
s Space
C Channel 9
[DC4] Terminator [Default is 01]
Option [A1]: FBI RS232
To enable the computer FBI Superfast protocol, program
option [A1] as “01.”When enabled, the computer output
will be as follows:
JRRLssssssAAAATZZEss[DC4]
Where:
J = FBI protocol identifier
RR = receiver number
L = Line number
s = spaces
AAAA = Account code.
T = Zone type
ZZ = Zone number, in hex.
E = Event code
NOTE: if E=0 and T=0 : listen in. [Default is 01]
Option [A3]: D6500 computer output
The DRL2E will emulate the Radionics D6500 RS-232 protocol
on pulse formats only. (00 = disable, 01 = enable)
Examples:
1. 3/1 format: Account code “123”with alarm code “1”,
(alarm) the computer output will be:
00 1RRLsssssss123sAss1[DC4]
01 1RRLsssssss123sAss1[DC4]
2. 3/1 format: Account code “123”with alarm code “B”,
(opening) the computer output will be:
00 1RRLsssssss123sOssB[DC4]
01 1RRLsssssss123sOsss[DC4]
3. 4/2 extended (or 3/2 or 3/1 extended): Account code
“1234”with alarm code “2”on zone “1”, (alarm) the
computer output will be:
00 1RRLssssss1234sAs21[DC4]
01 1RRLssssss1234sAs21[DC4]
4. 3/1 extended (or 4/2 or 3/2): Account code “234”with
alarm code “C”on zone “2”, (closing) the computer
output will be:
00 1RRLsssssss234sCsC2[DC4]
01 1RRLsssssss234sCss2[DC4]
Where RR = Receiver Number
L = Line Number
s = Space
[DC4] = Terminator
Please note that option [70] must be left as individual event
code when enabling this option. [Default is 01]
Option [A4]: BFSK RS232
When programming option [A4] as “01”, the BFSK format will
convert its Radionics D6500 computer output to a standard
protocol output. [Default is 01]
NOTE: This option also affects the modem option [9D].
Option [A5]: 7 Digit Pulse
This option allows the DRL2E to select Sescoa Super
Speed or 4/2 checksum pulse. Ordinarily, the DRL2E
cannot distinguish between these two formats, since they
are both 7 digit pulse. Program option [A5] as 00 to have
all incoming 7 digit pulse calls decoded as 4/2 checksum,
or 01 to decode as Sescoa Super Speed. [Default is 00]
Option [A7]: SK FSK2 RS232
The DRL2E provides two possible outputs to the computer.
Select 00 for protocol #1 or 01 for protocol #2. Please refer
to DRL2E Communication Fomats section (SK FSK
communication format) for more details.
