Comtech EF Data Documentation Update
Subject: Revised 5.6.4.7 Packed Configuration Status
Date: December 16, 2005
Document: UT-4500 Series, Up Converters, Installation and Operation
Manual, Revision 1, dated June 20, 2005
Part Number: MN/UT4500.EA1
Collating Instructions: Attach this page to page 73
Comments:
Revise paragraph 5.6.4.7 to read:
Change Specifics:
5.6.4.7 Packed Configuration Status
Configuration Status: <DEV/PACRCS_'cr'
Confirmation: >DEV/PACRCS_aaaabbbcdeffgghijkl'cr''lf']
where:
aaaa = # of 125kHz steps above base frequency1
bbb = # of 0.25 dB steps above 0.00 dB2
c = 1 if Transmitter ON, 0 if OFF, 2 if Cold
d = 1 if unit ONLINE, 0 if OFFLINE
e = 1 if Redundancy ON, else 0
ff = converter # (01-12,BU or 00 if e = 0)
gg = 00 if 'ff' is 00 (redundancy OFF)
gg = chain length (01-12) if 'ff' is BU
gg = XX if 'ff' = 01 - 12
h = A if Auto Mode, M if Manual3
I = 1 if Cold Start Enabled, else 0
j = 1 if Auto recovery enabled, else 0
K = 1 if an Ext. Ref is present, else 0
l = 1 if Remote Mode, 0 if Local Mode
Notes: 1 If the converter is 1 kHz step size, this will be the number of 1 kHz steps above the
base frequency. Also, this will be 5 bytes(aaaaa) long for model 4513X
converters with 125 KHz frequency step size. This will be 7 bytes(aaaaaaa)
long for all 1KHz step size converters.
2 If the converter is 0.1 -dB step size, this will be the number of 0.1 -dB steps above
the base frequency
3 If it is a backup Converter, it is always ‘A’.
4 If it is the primary converter, gg = P1 or P2 (single or dual polarity system.

Dual IF Rack Mount Converters
Comtech EF Data offers converters with the ability to switch the output IF frequency (Downconverters)
and/or the input IF frequency (Upconverters) from 70 MHz to 140 MHz or vice versa. The actual IF
bandwidth is maintained as the standard ±18 MHz (±20 MHz) of the 70 MHz configurations.
The software modification required for the implementation of the IF frequency switching are:
1. A front panel command to allow the output IF to switch from 70MHz to 140.
a. The new selection is located in the “Configuration” menu tree. The “normal”
FREQ/ATT/MUT menu is split into two. First menu screen now has “RF FRE= XXXXX
MHz on top line, with “IF FRE= XXX MHz” and “Rx= XXX” on second line. A second
menu screen contains the attenuator setting.
b. Mute behavior after changing the IF frequency is the same as the normal mute behavior
after changing the RF frequency.
2. A new remote command is implemented to accomplish the identical operation as in (1).
a. Command structure similar to the RF frequency selection.
The default is 70 MHz
Command Details
Set IF Frequency: <DEV/IFF_xxx'cr' (where xxx is either 140 or 70 without requiring
leading zero.
Confirmation: >DEV/IFF_xxx'cr''lf'] (where xxx is either 140 or 70 without requiring
leading zero.
Retrieve Frequency: <DEV/IFF_'cr'
Confirmation: >DEV/IFF_ xxx'cr''lf'] (where xxx is either 140 or 70 without requiring
leading zero.
Mute behavior after changing the IF frequency would be the same as the mute behavior after
changing the RF frequency.
Redundant operation
The customer can not “mix” dual IF converters with standard converters in a redundant system

1.2 FUNCTIONAL DESCRIPTION
The UT-4500 Series Up Converters are designed for use in communication systems, or in
satellite up-link data systems, for the transmission of SCPC, DAMA and TDMA
communication signals. The Up Converters can also be used in communications system
applications with full transponder HDTV and analog TV.
The converter is designed to be hard mounted in a standard 19-inch rack or cabinet, or to
be rack mounted using slide mechanisms provided with the converter to allow it to be
serviced without its removal from the rack. An internally mounted exhaust fan for
cooling is mounted on the rear of the chassis. An AC power connector, with an on/off
switch, is also located on the rear on the chassis. A six-foot AC power cord is supplied
with the converter.
All operator controls, indicators and displays for local and remote operation are located
on the front panel of the converter. Connectors for the external interface connections are
located on the rear of the converter chassis.
