Other information:


WESTWOOD ONE SELECTOR

The WestWood One box has a DC 9 Volt power supply.  There 
is a GREEN LED on the front panel labelled PWR.

This box receives data from the voice cue card in the 
satellite receiver via an RJ11 connector labelled 212A 
LINE.  The balanced output from the voice cue card is 
connected to the middle 2 contacts of the RJ11 connector.  
These are typically red and green wires on a pre-wired 
connector.

To receive DATA the DATS satellite receiver must be set to 
receive Satcom C5, Transponder 15 and the voice cue card 
must be set as follows: CHANNEL SELECT 19, SUBCHANNEL 
SELECT: 03.  After this connection is made the amber LED 
labelled "CD" should light.  If not connections are wrong.  
It must be at 0 Dbm into the Netwriter box.

Parallel printers will not work.

On the back of the WestWood One box is a DB25 labelled 
"Port 1".  The output pins are:   1- Frame Ground
 				2- Data Transmit
				7- Signal Ground
				20- Data Terminal Ready
 
The baud rate is usually 1200,n,8,1.

There is a TEST button on top of the box, in a very small 
hole.  Press and the amber LED on the front of the box 
marked ACT will light and it will output the following 
message: THIS IS A DATA DISTRIBUTION DEMODULATOR TEST.


MCCURDY DATA DEMODULATOR

This is a white box.

It has 4 LED's.  They are: POWER, CD, ACT, RST and ACTIVE 
RESET.

It has 3 output ports that are female DB25's.  They all 
output data on pin 2 which is transmit data.

The McCurdy demodulator has a reset button and a test 
button on the top of it.



The only receiver information available is that it uses a 
Fairchild Receiver.
