5. INTRODUCTION/OVERVIEW
The Arbitron Studio Grade Encoder (SGE) inserts inaudible symbols into the audio of
broadcasts according to Arbitron patented algorithms. The instrument described in this
document, the Encoding onitor ( ONITOR), is used to detect encoded audio program
material. The station engineer can use this instrument to validate that their station is
transmitting encoded program material. Arbitron strongly advises the station engineer to
use air return audio when connecting to the ONITOR, to detect cases where the SGE
has been accidentally ‘patched out’ of the audio stream.
RoHS Compliance (Restriction of Hazardous Substances) is the nickname given to the
European Union's directive 2002/95/EC on the restriction of the use of certain hazardous
substances in electrical and electronic equipment. RoHS seeks to reduce the amount of
hazardous materials entering electronic products.
The Arbitron “1000-1162-xx Encoding onitor, RoHS Compliant” is designed to meet
the requirements of the European Union's directive 2002/95/EC.
All of the other Arbitron Encoding onitors listed on the title page of this manual have
not been designed to meet the requirements of the European Union's directive
2002/95/EC.
5.1. S UGGESTED P LACEMENT IN A UDIO C HAIN
Arbitron recommends that the ONITOR be installed such that it receives program
material that has exited the transmitter or ‘over-the-air’ broadcasts. This will insure that
your media consumers are exposed to encoded program material.
The ONITOR operates optimally with a nominal average audio input level of +8 dBu.

6. INSTALLATION
6.1. I NSTALLING THE MONITOR
6.1.1. Place instrument into a 19” rack in an indoor environment.
6.1.2. Install securely using screws in each of the four front panel corners.
6.1.3. See Figure 2. Slide switch ‘S1’ to ‘600’ if 600 ohm input termination is desired or to
‘HI’ if a 12k ohm input bridging impedance is desired.
6.1.4. Connect the power cord to the ONITOR and to the same plug strip that supplies power
to the instruments that will be connected to the input of the ONITOR. The ONITOR
has no power switch. The ‘POWER’ indicator LED will be lit green.
6.1.5. DO NOT block or otherwise impede airflow through the sides of the instrument.
6.1.6. Connect the received program material signals into the connectors marked ‘IN’ on the
ONITOR.
If the program material is always mono and only one audio cable is used (single
channel mode), then the MONITOR can be configured for single channel operation.
In single channel mode, the channel A analog input must be used. The default
decoding mode is dual channel.

7. OPERATION
7.1. U SING THE MONITOR
The station engineer has been provided several monitoring options:
If desired, they can monitor the front panel LED. When the ONITOR is receiving the
correct encoded material, the front panel LED will be a CONSTANT GREEN. When
incorrectly encoded material is presented to the audio inputs, the front panel LED will
FLASH RED (see notes below).

If the engineer cannot always visually monitor the ONITOR front panel, the engineer
can use the rear panel ALAR connection. This connection provides both a normally
open and normally closed relays which will energize when indicating a loss of encoding.
This connection can be made externally to either an audible or visual indicator, or both.
It is highly recommended that the monitor’s ALAR connection should be used in
conjunction with your station’s current Air Fault Alarm system (or similar).
Provision has also been made for connection to a remote monitor device via RS232. See
below for specification of connection to both the ALAR and RS232 connections.
Note: The MONITOR has been configured with a nominal alarm delay of approximately
3 minutes. In other words the MONITOR will not assert an alarm condition until it fails
to detect the specified code for approximately 3 minutes. At that time the alarm relay
will close (or open) the LED will turn RED and a statement will be issued via the RS232
connection. When an encoded signal is applied to the input the MONITOR will release
the alarm condition immediately. Please see below for information on the specifics of the
alarm assertion.

7.2. C ONNECTOR D ESCRIPTIONS
7.2.1. Analog Input Connector Description
Input connectors on the ONITOR are female; thus, the mating XLR cable connector is
required to be male. Balanced XLR pin-out for the Arbitron ONITOR is as follows:
Pin 1- Shell or ground
Pin 2- High
Pin 3- Low

7.2.2. Alarm Connection Description
On the rear panel of the ONITOR is a DB9 male connector labeled, “ALAR
CONNECTION”. This connector provides a normally open and normally closed contact
switch to monitor the presence of encoded program material and to monitor the status of
the ONITOR itself. To allow remote monitoring of the ONITOR status, the
following connections are detailed:
CODE STATUS
Status = CODES Status = NO CODES
Pin 2 Open to pin 3 Shorted to pin 3
Pin 4 Shorted to pin 3 Open to pin 3
OPERATIONAL STATUS
Status = MONITOR
Normal
Status = MONITOR
Failure
Pin 7 Open to pin 8 Shorted to pin 8
Pin 9 Shorted to pin 8 Open to pin 8
The pins are connected to an internal relay of the ONITOR whose relay contacts are
rated at 0.3A max, 24VDC. If the front panel LED is SOLID RED and the onitor
failure alarm is asserted, then a system failure has occurred.

7.2. . STATUS (RS-2 2) Description
On the rear panel of the ONITOR is a DB9 female connector labeled, “STATUS RS-
232”. This is an RS-232 serial port that is output only. To allow remote monitoring of
this ONITOR, the following connections are detailed:
a. Pin 3 – Transmit Data (TD)
b. Pin 5 – Chassis ground (Common)
To communicate with the ONITOR, the following hardware is required.
• PC (Desktop or Laptop) running Windows 95 or later software, and that has a 9 pin
‘D’ serial port. (Other computers/software configurations may work, but have not
been tested.)
• RS-232 DB-9 Cable with a Null- odem adapter
Plug one end of the RS-232 DB-9 cable with a Null- odem adapter into the ‘STATUS
PORT’ in the rear of the Encoding onitor and the other end into the CO Port of the
PC to allow remote monitoring.
On the front panel of the ONITOR is a DB9 female connector labeled “Service Port”.
THE SERVICE PORT CONNECTOR IS FOR AUTHORIZED USERS ONLY. Do
not use this port unless authorized to do so by Arbitron.
A RS-232 DB-9 Cable and a special adaptor/connector (per Arbitron drawing number
1002-0610) are required to use the features of the service port.

7.5. S TATUS MESSAGE F ORMATS
7.5.1. Boot-up Messages
System boot-up starts when power is applied to the ONITOR. If the HyperTerminal is
active during system power on, as the system is booted up the rear panel ‘STATUS’
serial port sends out the following messages:
<NOTE@P[Encoding Monitor Boot Loader][Vx.xx]>
<NOTE@P[Main program checksum][Valid]> to indicate self test pass
or
<NOTE@P[Main program checksum][Invalid]> to indicate self test fail.
<NOTE@P[Encoding Monitor Main][Vx.xx]>
7.5.2. Encoding Present Messages
When the onitor has determined that a valid code is present in the program material, the
status port sends out the following messages:
<NOTE@P[000x][station_name]>
where x = 0 - 9.
A new output line is displayed every 20 seconds. (Note: This is not indicative of the
detection rate.) The number of each line ( e.g., 0001, 0002) is output to show activity on
the line, since the first portion of this message may not change.

7.6. N O E NCODING M ESSAGES
If a valid code is not detected in the program material, the status port sends out the no
code message:
<NOTE@P[000x][Encoding not detected]>
where x = 0 - 9.
A new output line is displayed every 20 seconds. The number of each line ( i.e. 0001,
0002) is output to show activity on the line, since the first portion of this message may
not change.
If a code is detected in the program material, but the detected code is not one of the
identification codes programmed into the unit, the status port sends out the unknown
station message:
<NOTE@P[000x][Unknown Station]>
where x = 0 - 9.
A new output line is displayed every 20 seconds. The number of each line ( i.e. 0001,
0002) is output to show activity on the line, since the first portion of this message may
not change.
