12 Operating Instructions (From Drake

Digital Headend Control Program)

Operating Instructions - From Drake Digital Headend

Control Program

1) Confirm that all connections to the EH24 and its installed

encoder modules have been made as described previously.

Connect a serial cable from the RS232 IN connector on the

EH24 to the serial port on the PC. (This discussion assumes

that the Headend Control Program has already been

installed on the PC as per the instructions supplied with the

software.)

2) Activate the software. You

should see a screen similar to

FIGURE 1 at right.

3) Click on the 'Setup New

Headend' button. This will

bring up the screen shown in

FIGURE 2. Type in the name

of the headend in the

'HeadEnd Name' field and

click on 'OK'. In this case we

have typed in EH24. Then

select the 'PC Baudrate' and

'Using Port'. If you intend to

use a modem instead of a

direct connection, make that

selection using the 'Connect

via:' radio buttons, and type in

the phone number of the

desired modem in the 'Number

to dial' window. Then click

'OK'.

4) You will be presented with

a screen similar to the one

shown on FIGURE 3. Click on

the EH24 tab, and click on the

box representing the EH24 unit ID of the unit you are

programming. In this example we selected Unit ID #1. Then

click on the 'View Edit' button.

Select EH24 Unit ID

This will bring up the screen shown in FIGURE 4. Click on

the Encoders tab and select the number of the encoder you

choose to program. Set each parameter to the desired

value. Select the number of the next encoder and set each

of its parameters.

Repeat for each

encoder which you

desire to program.

Note that if the value

of the parameter

selected in the left

column differs from

the value of that

parameter in the

selected encoder in

the EH24 shown in

the right column, that

value will appear in

red.

5) Click on the 'QAM

Output' tab and set

each parameter using

the same technique

FIGURE 1

used when setting

encoder parameters.

6) Click on the 'ASI Output' tab and set its values to the

desired values as using the same techniques as above.

7) Click on the 'Set Major/Minor Channel Numbers' button.

You will be presented with a screen shown in FIGURE 5.

8) This screen allows the

user to reasign MPEG

numbers as well as new

major and minor channel

numbers.

9) Once the selections

have been made, click on

the 'Download to EH24'

button. This will transfer

all selections on this

screen as well as all

selections made on the

EH24 Tab

previous screens to the

EH24 and its installed

SDE24 modules. Close

this screen by clicking on

the 'X' in the upper right

hand corner of the

screen.

10) You will note that all

of the items in the right

hand columns in the

Encoders, QAM Output

and ASI output screens

are now black and agree with the selections made in the left

hand columns.

11) Additional information on the operation of the Drake

Digital Headend Control Program can be found in the
