1.0 General
1.1 Equipment Description
The 2416-425 Downconverter has four individual channels, each one converts 2000 to 2500 MHz to 70 MHz in
125 kHz steps using PLL in “exact frequency mode” with low group delay and flat frequency response.
Synthesized local oscillators (LO) provide frequency selection. Multi-function push button switches select the
input frequency, gain, and other parameters. Front panel LEDs provide indication of DC power, PLL alarm or
Remote operation. Gain is adjustable manually over a 0 to +30 dB range. The frequency and gain of each
channel are also remotely selectable. Parameter selection and frequency and gain settings appear on the LCD
display. Connectors are BNC female for the RF IN, and BNC female for the RF OUT and external 10 MHz
reference input and output. The table below shows available options. The 2416-425 is powered by a 100-240
±10% VAC, 47-63 Hz power supply, and is contained in a 1 3/4” X 19” X 16” rack mount chassis.

1.4 Environmental Use Information
A.Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions
located in the user manual furnished by the manufacturer of your equipment rack.
B. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
C.Elevated operating ambient temperature - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra. (Maximum Recommended Ambient Temperature)
D. Reduced air flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Additional space between units
may be required.
NOTE: Additional space between units is recommended if multiple Quad-channel units
are to be stacked in the same rack.
Fan Option, W113, may also be selected for enviroments with poor air flow and/or where additional space
between units is not possible.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used, when addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connection to the Branch
(use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS
emission problems.

Figure 2.5 shows the various Front Panel LCD Displays that you will see during the Power Up sequence and
the Settings modes. The first two displays (Power Up, displaying Model Number, Rev. Level and IP Address
are only displayed briefly during the Power On sequence.
The Normal Display is what you will see while the unit is in normal operating mode.
When power is first applied, the LCD display goes through three steps.
1. The model number and options will be displayed.
2. The unit reads the IP address (if Ethernet option installed) and displays IP Address.
3. The current frequency setting of each channel downconverter is displayed.
The unit is now operational and ready for any changes the operator may desire.
The Menu Displays are those displays you will see when making any Setting changes.
NOTE: Mode Settings and Values will be changed as you select them, but they will NOT BE SAVED if you
do not select Save and YES. If you do not wish to save any settings you can either select Save and NO or you
can NOT press the Menu/Execute switch and simply do nothing for approximately 30 seconds and the unit will
return to the previously saved Mode and Value Settings.
The “R” shown on the menu is a Return setting that allows you to Stop and Save wherever you are in the
Settings mode, without going through all the Menu screens.
2.5.1 Control Switches
1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the
Menu/Execute switch and completed by pressing the Menu/Execute switch (Figure 2.3).
2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor
left or right (Figure 2.3).
3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions:
a. During frequency, gain changes, the vertical movement will raise or lower the number in
the direction of the arrows (Figure 2.3).
b. For other functions such Mute on/off, the vertical switch will alternately turn the function
on or off regardless of the direction operated.

2.5.2 Frequency Changes
At any time during the modification process, if you have made a mistake and do not wish to save the changes
you have made, do not press the Menu/Execute switch; simply do nothing for approximately 30 seconds,
and the system will return to the normal operating mode or scroll to “R” and push the menu/Execute switch
and select “NO” in the “SAVE SETTINGS?” window.
To change the FREQUENCY:
Operate the Menu/Execute switch until you get to the menu item you want to change.
See Figure 2.5 for the sequence of menu options.
NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE
SAVE MENU AND INDICATE YOU WANT TO SAVE THE CHANGES.
2.5.3 Gain Changes
When you get to this menu note that the gain changes will be made as you make them but if you do not wish
to save the changes you have made, scroll to “R” and push the Menu/Execute switch and select “NO” in the
“SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for
approximately 30 seconds, and the system will return to the normal operating mode.
To change the DOWNCONVERTER GAIN:
Push the Menu/Execute switch to get to the gain setting.
See Figure 2.5 for the sequence of menu options.
NOTE: THE GAIN WILL BE CHANGED AS YOU ADJUST THE NUMBERS. HOWEVER,
THE VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE
SETTINGS WINDOW.
2416-425 Manual Page 16 11/17/21

2.6 Menu Settings
All program changes must start with the operation of the Menu/Execute switch and must also end with the
operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed,
none of the changes will take effect. If programming is initiated and no operator action takes place for
approximately 30 seconds (before the final press of the Menu/Execute switch) the display will revert to its
previous status and you will need to start over.
Alarm indications appear on the LEDs (See figure 2.3). An alarm condition will occur if any local oscillator
phase lock loop (PLL) comes out of lock. The Remote LED will light when you select the Remote mode.

3.0 Ethernet Interface Installation and Operation (Option W8, W18 or W28)
This manual applies to Cross Technologies products equipped with a 10/100 Base-T compatible Ethernet
interface for control and monitoring of its operating parameters. The following sections describe the operation
and setup of those interfaces. An HTML script interface allows the user to monitor and control the converter
using a standard web browser. SNMP (Simple Network Management Protocol) is also supported.
Contact Cross Technologies for the SNMP MIB file.
3.1 Connection
3.1.1 Direct Connection to a PC
For control from a local PC, attach the 2416-x25 Ethernet port to the Ethernet network connector on the PC
using a crossover RJ-45 cable.
3.1.2 LAN Connection
For LAN connections, attach the 2416-x25 Ethernet port to the LAN using a normal RJ-45 cable. Use any PC
on the LAN to connect to the 2416-x25.
3.2 Ethernet Configuration
Each product must be configured with an appropriate IP address, Netmask, and Gateway assigned by your
network manager. The 2416-x25 is preset at the factory with a static address that is briefly displayed on the
LCD Display during Power On Sequence (192.168.123.2 is the default). The device server in the 2416-x25
has a built in HTTP based configuration manager that is used to configure network settings. To access the
configuration manager open a web browser and enter the IP address of the product in the browser's address
field. The window shown in Figure 3.0 will appear. As delivered, there is no password set. Choose your user
name and password here or leave those fields blank and click OK to proceed to the Configuration Manager web
page screen, Figure 3.1.
