MODEL 4116-285-2450 Block Downconverter, Weather Resistant
1.0 General
1.1 Equipment Description
The 4116-285-2450 Block Downconverter converts 28.5 - 30.0 GHz to 0.95 - 2.45 GHz. Front panel LEDs
indicate DC Power and PLL Alarms. The RF to L-band gain is +30 ± 3 dB maximum at Fc and is adjustable in
0.5 ± 0.5 dB steps. Connectors are 2.92 mm for RF In, RF Monitor and SMA for the external reference input
and output, and Type N, female for L-band out. Gain 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. The unit is powered by a 100-400 ±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.

2.1 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.
2.2 M&C Commands
The following tables summarize the commands and status queries applicable to the
4116-285-2450 frequency converter.
*PLEASE NOTE: The two character {aa} prefix, shown in the table below, is present ONLY when RS485 is selected.

2.4 ETHERNET Interface Installation and Operation
The 4116-285-2450 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 4116-285-2450’s Ethernet port to the Ethernet network connector on the
PC using a crossover RJ-45 cable.
LAN Connection:
For LAN connections, attach the 4116-285-2450 Ethernet port to the LAN using a normal RJ-45 cable.
Use any PC on the LAN to connect to the 4116-285-2450.
2.4.2 Ethernet Configuration
Each 4116-285-2450 must be configured with an appropriate IP address, Netmask, and Gateway assigned by
your network manager. The 4116-285-2450 is set at the factory with a static address of 192.168.123.2. The
device server in the 4116-285-2450 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
4116-285-2450 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.
Figure 2-A: Password Screen
4116-285-2450 Manual, Rev. 0 Page 9 02/11/21

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 on apply settings to apply the new settings in the device server.
4116-285-2450 Manual, Rev. 0 Page 10 02/11/21

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 (page 11) shows the web page from a model 4116-285-2450 frequency converter.

4116-285-2450 Manual, Rev. 0 Page 11 02/11/21

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 4116-285-2450 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.
Figure 2-E: - Telnet®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 an 18-pin MS3112E14-18S connector as shown in Table 2.6.1. The Ethernet signals connect via a standard
RJ45 connector (RJF6G).

2.7 Installation/Operation
Installing and Operating the 4116-285-2450 Block Downconverter:
1. Connect a -50 dBm to -30 dBm signal to RF INPUT J1), (Figure 2.5).
2. Connect the L-BAND OUTPUT to the external equipment.
3. 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.
4. If a custom length power cable must be made, refer to description below for connections*.
5. Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.5).
6. Set the gain so that the output level is always within the range of +30 to 0 dBm.
(See Table 2.0 and 2.6.1).
7. 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
reference that is inserted at J2) via Ethernet or serial command. (See Table 2.0 and 2.6.1).
8. 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).
9. AC Fuse - The fuse is a 1A/250V, 1.25” x .25” (slow blow) and is inserted in the fuse F1 position.
NOTE: If a fuse continues to open, the power supply is most likely defective.
