OPERATING INSTRUCTIONS – FROM THE FRONT PANEL
1) Connect video and audio inputs to desired encoder modules. Note, as viewed from the rear, the number 1
program will be on the left, the one closest to the RF output connector. The number 2 program will be the next
input to the right.
2) Connect the outputs as desired.
3) Plug the EH24A into AC power. Allow 30 to 90 seconds for boot-up.
4) From the front panel, use the ENCODER SELECT buttons to choose among EH24A settings and settings for each
encoder. Use the ENTER button to enter program mode and to save settings in memory. Use left and right arrows to
select a parameter and then use the up or down arrows to change its value. Parameters values can only be changed
when the unit is in the program mode as indicated by slow flashing of the front panel display. To enter program mode,
press the ENTER key and hold for 2 to 3 seconds.
5) Press ENTER for 3 seconds to enter program mode.
6) Repeatedly press the ENCODER SELECT right or left arrow until the display shows: SETUP EH24A.
7) Repeatedly press the left or right arrows (on either side of the enter button) until the display reads ENCODER1.
Press up or down arrows to select which output or both outputs that this encoder is to output to. Then press the right
arrow once to advance to ENCODER 2. Choose output for this one. Proceed in this manner until all encoders have
been directed to the desired outputs. ENCODERs 1 and 2 will be the first module, 3 and 4 the second module, 11
and 12 the sixth module, etc. If an encoder is installed but you don’t plan to use it, be sure to choose the DISABLED
choice for any such encoders.
8) Press the right arrow again after setting the 12th encoder. This should produce the QAM MGT/VCT screen.
Usually select TVCT by using up or down arrows.
9) Press right arrow again and observe the QAM MODE screen. Use up or down arrows to select QAM mode. For
example, QAM-256B would select 256 QAM with annex B FEC (DigiCipher FEC).
10) Press right arrow again and observe QAM SYMRATE. Set to PRESET. PRESET will be 5.057 MS/S for QAM-
64B or 5.3606 MS/S for QAM-256B, etc. If a nonstandard rate is desired, choose MANUAL.
11) Press right arrow again and observe INTERLEAVER. Select I128,J1 unless you have a special requirement.
12) Press right arrow again and move to the OUTPUT FORMAT. Choose NORMAL. For testing/level setup –
temporarily choose CW to produce a CW carrier in the center of the channel. Other PRBS choices are for testing
only.
13) Press right arrow again and observe OUTPUT CHANMAP. Select the desired plan, usually CATV.
14) Press right arrow and observe OUTPUT CHANNEL. Select desired channel. The RF channel number being set
will be used as the major channel number in the output stream.
15) Press right arrow and observe RF OUT. Choose desired RF out level.
16) Press right arrow and observe UNIT ID. If not using Ethernet remote control, choose 0.
17) Press the right arrow and observe Ethernet BAUDRATE. Set to 4800 unless otherwise directed.
18) Press the right arrow and observe that you are back to the ENCODER 1 screen.
