MODEL 713 TECHNICAL SPECIFICATIONS

Standards Supported:

European CENELEC and United

States NRSC.

RDS Applications Supported:

PI, PS, PTY, TP, TA, RT, AF, DI,

M/S, FFG. (A detailed explanation of

these applications begins on

Page 7.)

Operating Modes:

(1) Loop-Through:

In loop-through operation, the RDS

subcarrier is internally mixed with

the MPX input and the combined

signal is delivered to the

RDS OR

MPX OUTPUT

. The encoder has

unity gain in the loop-through mode

and accepts a maximum level of 6

volts peak-to-peak corresponding to

±75kHz carrier deviation. Loop-

through includes a failsafe Bypass

function so that program audio will

not be lost if the encoder loses power.

(2) Sidechain:

In sidechain operation, only the RDS

subcarrier appears at the

RDS OR

MPX OUTPUT

. This signal is then

combined with the FM multiplex

baseband in the stereo generator or

FM exciter. The monitored MPX (or

TTL sync) applied t the

PILOT OR

MPX INPUT

connector is used solely

to synchronize the 57kHz RDS sub-

carrier with the 19kHz stereo pilot.

NOTE:

The 713 is shipped from the

factory in the Sidechain mode.

Pilot or MPX Input:

An unbalanced, bridging BNC input

that accepts either the composite/

multiplex (MPX) signal or 19kHz

TTL-level pilot sync from the stereo

generator.

RDS or MPX Output:

An unbalanced, low-impedance BNC

output to feed a wideband input of

the FM exciter.

RDS Injection Level:

Continuously adjustable between

zero and 2 volts peak-to-peak.

USB Port:

Front-panel USB connector for quick

computer programming of static

data.

Serial Data Port:

RS-232 port (DB-9) for static pro-

gramming and dynamic messaging.

2400, 4800, 9600, 19200, 39400,

57600 or 115200 baud; 8, N, 1, plain-

text ASCII protocol.

LAN Port:

RJ-45 connector; user-programmable

DNS for full TCP/IP programmabil-

ity via Local Area Network or Inter-

net.

TA Switching:

The temporary TA flag is set either

by a software command or with a

momentary contact closure through a

rear-panel connector.

Power Requirements:

105 130VAC or 210 255VAC,

50/60Hz; 10W.

Size and Shipping Weight:

1¾ H x 19 W x 7 D (1U); 7 lbs.
