MODEL 4116-31-2831 Tri-Band Block Downconverter, Weather Resistant*
1.0 General
1.1 Equipment Description
The 4116-31-2831 Ka-band Block Downconverter converts 28.3 - 31.0 GHz to 0.95 - 1.95 GHz in three selectable fixed bands. Front
panel LEDs indicate DC Power and PLL Alarms. The RF to L-band gain is +30 dB maximum and is adjustable in 0.5 ± 0.5 dB steps.
Connectors are 2.92 mm for RF In, SMA for external reference input and output, and Type N (all female) for L-band out. Gain, band
select, and internal 10 MHz frequency are controlled by the Ethernet M&C. In AUTO, the 10 MHz reference stays in external if the
external level is in the +2 to +8 dBm range. It is powered by a 100-240 ±10% VAC power supply, and is mounted in a 8”W X 6”H X
16”D Weather Resistant* enclosure.
NOTE: *Weather Resistant enclosures are designed to be water resistant for installation in an outdoor enclosure/antenna hut OR
mounted outdoors on an antenna assembly at their specified temperature ranges. They are designed to be located “out in the
elements” (water, sleet, snow, etc.) but they are not designed to be “submerged under water”. If an extended temperature range is
required, there is an Extended Temperature option (Option W21; -30˚C to +60˚C) available at an additional cost. Contact Cross for
quote.

2.0 Installation
The 4116-31-2831 Tri-Band Block Downconverter consists of a 8”W X 6 “H X 16”D Weather resistant*
enclosure. A switching, ± 12, +24, +5 VDC power supply provides power for the internal assemblies.
The 4116-31-2831 can be secured to a mounting plate using the 4 holes on the bottom of the front and rear
panels. See Figure 2.5 for mounting dimensions.
2.0.1 Connection to AC Input Power
The 4116-31-2831 utilizes a pre-assembled AC power input cable as described below.

2.1 Message Protocol
The serial format for the RS232/RS422/RS485 port is 9600 baud, 8 data bits, no parity, and 1 stop bit.
All messages consist of ASCII printable characters so standard terminals and terminal emulator programs may
be used to control and monitor the unit. All messages begin with the open bracket character “{”(ASCII 0x7B)
and end with the close bracket character “}” (ASCII 0x7D). Messages consisting of commands to set or change
operating parameters and modes of the unit begin with “C” (ascii 0x43) followed by a command specific
character. Messages consisting of queries to report operating parameters and modes begin with “S”
(ASCII 0x53) followed by a parameter specific character.

2.4 ETHERNET Interface Installation and Operation
The 4116-31-2831 Tri-Band Block Downconverter is equipped with a 10/100 Base-T compatible Ethernet
interface for control and monitoring of its operating parameters. 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.
2.4.1 Methods of Connection
Directly Connected to a PC:
For control from a local PC, attach the 4116-31-2831’s Ethernet port to the Ethernet network connector on the
PC using a crossover RJ-45 cable.
LAN Connection
For LAN connections, attach the 4116-31-2831 Ethernet port to the LAN using a normal RJ-45 cable.
Use any PC on the LAN to connect to the 4116-31-2831.
2.4.2 Ethernet Configuration
Each 4116-31-2831 must be configured with an appropriate IP address, Netmask, and Gateway assigned by
your network manager. The 4116-31-2831 is set at the factory with a static address that is written on a tag
attached to the unit. The device server in the 4116-31-2831 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 4116-31-2831 in the browser's address field. The window shown in Figure 2-A 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.
4116-31-2831 Manual, Rev. 0 Page 10 08/18/21

Figure 2-A: Password Screen
Figure 2-B: Configuration Manager Screen
In the left frame of the configuration manager click on Network to display the Network Settings screen.
Enter the IP address, Subnet mask, and Gateway address with delimiter dots (example: 192.168.192.47).
Click to apply settings in the left frame to apply the new settings in the network device.
4116-31-2831 Manual, Rev. 0 Page 11 08/18/21

2.4.3 Web page M & C
Enter the following address in a web browser to access the M & C Web page:
http://<ip address of 41xx>/serial/0/setup.htm where <ip address> is the IP address
of the unit. Figure 2-C shows the web page from a model 4116-31-2831 frequency converter.
Figure 2-C: Model 4116-31-2831 Web page
2.4.4 SNMP Configuration
Setting of SNMP parameters such as Community Write and Community Read strings requires a Telnet®
connection to port 9999. The following instructions explain how to establish such a Telnet®connection using
Windows XP's Hyper Terminal utility .
Start the Hyper Terminal application and select “New Connection” from the “File” drop down menu. The next
screen is a “Connect To” dialog box. Select TCP/IP (Winsock) from the “Connect” using drop down menu.
Enter the IP address of the 4116-31-2831 in the “Host Address:” field and 9999 in the “Port Number” field.
Figure 2-E shows an example of the Hyper Terminal settings required to access the SNMP configuration menu.
4116-31-2831 Manual, Rev. 0 Page 12 08/18/21

Figure 2-E: Telenet®Settings in Hyper Terminal
Once the Telnet®connection is established you will be prompted to “Press Enter for Setup Mode.” Press enter
and a menu of device server configuration options will appear (see Figure 2-F). Select menu item 3, “SNMP
configuration.” You will be prompted to enter SNMP community read and write strings. After setting your
desired community strings you will be prompted to “Enter IP addresses for SNMP traps:” You must enter at
least one and up to four IP addresses of SNMP managers that will access the unit. This is required even though
SNMP traps are not implemented. The unit will not process SNMP SET and GET requests from an SNMP
manager unless the IP address associated with that manager is entered in the device server.

2.6 Physical Interface
All 4115 and 4116 units provide a RS232/RS422/RS485 interface port and a 10/100 Base-T Ethernet port.
Both ports are available when the unit is installed and powered up. Commands may be sent to either port at any
time and they will be processed in the order that they are received. The RS232/RS422/RS485 signals connect
via a multipurpose MS3116, 18 pin connector as shown in Figure 2.5. The Ethernet signals connect via a
standard RJ45 connector.

2.7 Installation/Operation
Installing and Operating the 4116-31-2831 Tri-Band Downconverter
1. Connect a -30 dBm to -10 dBm signal to the RF INPUT, (Figure 2.5)Using the pre-assembled AC
power input cable (furnished), connect 100-240 ±10% VAC, 47 - 63 Hz to AC IN connector
on the front panel.
2. If a custom length power cable must be made, refer to description below for connections*.
3. Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.5).
4. Set the gain for +30 to 0 dB insuring that the output level is always in the range of -20 to 0 dB.
5. Select either INT (for internal 10 MHz ref), AUTO (for internal 10 MHz ref UNLESS an external
10 MHz, +2 to +8 dBm signal is connected to J2), or EXT (for external 10 MHz, +2 to +8 dBm ref
that is inserted at J2) on front panel switch S1 (Figure 2.5).
6. Check that a 10 MHz signal is present at the 10 MHz REF OUTPUT at the same level as the input,
±0.5 dB (J4 - Figure 2.5).
7. AC Fuse - The fuse is a 1.25” x .25” - 1.0 amp ( slow blow) and is inserted in the fuse F1 position.
NOTE: If a fuse continues to open, the power supply is most likely defective.
CAUTION: When checking or replacing the fuse, do not over tighten the fuse holder cap.
This can displace the cap’s O-ring and the weatherproof seal will be lost.
