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.

2.0 Installation

The 4116-285-2450 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 4116-285-2450 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.)

2.1 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.
