GENERAL PRECAUTIONS.
The following are general precautions that are not related
to any specific procedure and, therefore, do not appear
elsewhere in this publication. These are precautions that
personnel must understand and apply during various phases of
instrument operation or service.
WARNING
•Potentially lethal voltages are present in this
instrument. Serious shock hazards from voltages
above 70 volts may exist in any connector,
chassis, or circuit board. Observe the following
precautions:
•To minimize shock hazard, the instrument chassis
must be connected to an electrical ground. Using
the supplied three-conductor power cable ensures
that the instrument can be firmly connected to the
ac power source and electrical ground at a
grounded power outlet. If using a 3-2 wire
adapter be sure to connect the ground lead to earth
ground.
•Use the buddy system any time work involving
active high voltage components is required. Turn
OFF the power before making/breaking any
electrical connection. Regard any exposed
connector, terminal board, or circuit board as a
possible shock hazard. DO NOT replace any
component or module with power applied.
•If test conditions to live equipment are required,
ground the test equipment before probing the
voltage or signal to be tested.
•Personnel working with or near high voltage
should be familiar with modern methods of
resuscitation.
•DO NOT wear jewelry (rings, bracelets, metal
watches, and/or neck chains) while working on
exposed equipment. Be very cautious about
using hand tools near exposed backplanes, bus
bars, and/or power supply terminals. Use
properly insulated tools. When making test
connections to the power supply terminals and
bus bars, use only insulated probe tips.
•Verify that the instrument is set to match the
available line voltage and the correct fuse is
installed.
•DO NOT install substitute parts or perform any
unauthorized modification to this instrument.
Contact Weinschel Corporation to acquire any
information on replacement parts or returning
the instrument for repair. Unauthorized
modification can cause injury to personnel and/or
destruction of the instrument.
•Operating personnel must not remove instrument
covers. Component replacement or adjustments
MUST BE performed by qualified service
personnel.
•DO NOT operate the instrument near or in the
presence of flammable gases or fumes.

9. GENERAL INFORMATION:
1-1 PURPOSE: This manual contains setup and operation information for the Aeroflex / Weinschel’s 8310-XXX-XN
Series of Programmable Attenuator Units with Ethernet Control. The manual also provides component location,
reference designators, part numbers, and nomenclature to identify all the assemblies and sub-assemblies of the
Attenuator Unit.
1-2 SCOPE: This manual is to be used in conjunction with the operation and maintenance of an 8310-XXX-XN Series
of Programmable Attenuator Units with Ethernet Control. The manual also provides a description of each assembly;
assembly parts list; block diagrams: and general maintenance procedures to maintain the instrument.
1-3 EQUIPMENT DESCRIPTION: Aeroflex / Weinschel’s 8310-XXX-XN Series of
Programmable Attenuator Units with Ethernet Control represents a new concept in
programmable attenuation for bench test and subsystem applications. Standard Model
8310-XXX-XN designs house and control various Aeroflex / Weinschel Programmable
Attenuator Models (3200T, 3400T, 150T, and 4200 Series) via front panel controls or
standard communications interfaces including Ethernet, GPIB (IEEE-488) and RS-
232/RS-422/RS485. Special configurations also exist where the RF section is designed
to specific customer requirements which can contain to multiple programmable
attenuations used in-conjunction with other coaxial devices such as switches, power
combiners, directional couplers, and filters creating single or multi-channel subsystems.
1-4 USING THE 8310-XXX-XN: The 8310-XXX-XN Series provides front-panel and computer control for up to four
channels of attenuation, RF switching, or other functions. The 8310-XXX-XN combines the features of the Aeroflex /
Weinschel 8210A Device Controller with a front panel user interface to form a flexible, easy to use solution. Most
8310-XXX-XN Series are single channel configurations where RF signal is routed through either the front or rear
mounted Ports A & B connector (Ports A-A if the RF is routed front to rear) to a single or multiple Aeroflex / Weinschel
programmable attenuators thus creating CH1 (Channel 1). Note that when a Port is in use the Port indicator will be
illuminated. Dual channel units typically use Ports A and B for CH1 and Ports C and D for CH2 (Ports A-A if the RF is
routed front to rear for CH1 and Ports B-B for CH2). Multi-channel (3-4) units are generally routed front to rear and
configured as follows:
CH1 Port A (Front) to Port A (Rear)
CH2 Port B (Front) to Port B (Rear)
CH3 Port C (Front) to Port C (Rear)
CH4 Port D (Front) to Port D (Rear)
For specialized configurations refer to supplemental
information in the front of this manual for details.
Typically Aeroflex / Weinschel digital attenuators are bi-directional and the RF signal can be applied to either Port
connector. Channels can be selected by toggling the front panel CHAN button until the desired CH1-CH4 indicator is
illuminated. Repeated depressions of the CHAN key will select the next available channel. The main display will show
the current attenuation setting of the channel. A new attenuation setting in dB may be entered using the INCR/DECR
or ENTRY keys. The front panel STEP key allows the user to define the attenuation step size used by the INCR and
DECR keys. Remember that the attenuation step size (resolution) is limited to the physical size of the internal
attenuator cells. For example a 0-70 unit with 10 dB steps can only be adjusted in 10 dB increments but larger
increments such as 20, 30, 40 dB can be set using this key.
The REL key allows the user to set relative mode for attenuators. When turned on, the currently displayed attenuation
value is used as a reference value from which the attenuation may be set. In this mode, attenuation values may be
positive or negative from the reference setting. When REL is
turned off, the display returns to the actual attenuation setting for
the channel. Refer to Section 5 for more detailed information
about the front panel keys and indicators. All 8310-XXX-XN
Series functions can also be controlled via standard
communications interfaces including Ethernet, GPIB (IEEE-488)
and RS-232/RS-422 /RS485. Refer to Section 6 for bus setup
and operating instructions when using the 8310-XXX-XN Series
in the remote mode.

1-5. UNPACKING AND INSPECTION: Upon unpacking the equipment, retain the shipping container and packing
material for future shipment for recalibration. Perform the following initial inspection:
a. Carefully look at the outside of the shipping container for discoloration, stains, charring, or other signs of
exposure to excessive heat, moisture, or liquid chemicals. Check for any physical damage to the shipping
container such as dents, snags, rips, crushed sections or areas, or similar signs of excessive shock or
careless handling.
b. With the equipment and any accessory package removed from the shipping container, check each item
against the packing list or Items Supplied List. If any items are missing, contact the Weinschel Corporation
Customer Service Department.
c. Carefully inspect the equipment looking for dents, deep scratches, damaged or loose connector, or any other
d. signs of physical abuse or careless handling. If damage is found, forward an immediate request to the
delivering carrier to perform an inspection and prepare a concealed-damage report. DO NOT destroy any
packing material until it has been examined by an agent of the carrier. Concurrently, report the nature and
extent of damage to Weinschel Corporation, giving equipment model and serial numbers, so that necessary
action can be taken. Under U.S. shipping regulations, damage claims must be collected by the consignee;
DO NOT return the equipment to Aeroflex / Weinschel until a claim for damages has been established.
1-6. RESHIPMENT: Use the best packaging materials available to protect the unit during storage or reshipment.

4. FRONT PANEL CONTROLS & INDICATORS:
The following paragraphs provide setup and general guidelines for operating the Model 8310-XXX-XN
Programmable Attenuator Unit and its different bus configurations.
Figure 3. 8310-XXX-XN Series Front Panel
ENTRY keys: The numeric entry keys allow the user to directly enter numeric values. When using
the keypad, values are not updated until the ENT (enter) key is pressed. The Minus (-) and CE (clear
entry) functions may be accessed via first depressing the SHIFT key.
INCR & DECR: The INCR and DECR keys allow settings to be scrolled from their current value.
Unlike the ENTRY keys, the new setting is updated immediately without the use of the ENT key.
CHAN: Allows the selection of the current channel, as indicated by the CH1-CH4 indicators.
Repeated depressions of the CHAN key will select the next available channel. The main display will
show the current setting of the channel.
REL: This key control allows the use of a relative mode for attenuators, as indicated by the REL
mode indicator. When turned on, the currently displayed attenuation value is used as a reference
value from which the attenuation may be set. In this mode, attenuation values may be positive or
negative from the reference setting. When REL is turned off, the display returns to the actual
attenuation setting for the channel.
STEP: This key allows the user to change the attenuation step size used by the INCR and DECR
keys. When turned on, as, indicated by the STEP indicator, the current step size is displayed in the
main display, and a new value may be entered using the INCR/DECR or ENTRY keys. The step size
may be set to any multiple of the intrinsic step size for the currently selected channel.
MENU: Invokes the menu functions. Menu selections may be made via the INCR and DECR keys.
(NOTE: menu functions are currently not implemented as of 3/8/99)
AUX1/AUX2: The function of these keys is user-programmable via remote operation. They invoke
any currently defined AUX1 and AUX2 macros. Refer to the macro programming section for
information on creating macro definitions.
LOCAL: This key places the 8310-XXX-XN in local operation mode, unless the key function has
been overridden via an IEEE-488.2 local lockout or execution of the LOCKOUT command.
ADDR: This key displays the current IEEE-488.2 address. The address may be changed from the
front-panel, however, the initial setting at power on is derived from the rear-panel address switch.

5. REMOTE OPERATION:
The following paragraphs provide setup and general guidelines for operating the Model 8310 using an
external controller.
5-1. COMMUNICATIONS INTERFACE: The unit provides for control via a number of interface methods, including
IEEE 488.2, RS232 serial, and 10/100 baseT Ethernet. Interface functions are split between two assemblies:
1). The main controller (generically referred to as the 8210A),
2). The exadeci control interface.
The 8210A is responsible for control of the RF devices, and handles GPIB and RS232 communications. The
Ethernet control interface utilizes a Lantronix Xport™ Ethernet to serial device server which allows the 10/100baseT
Ethernet network to communicate to the 8210A via the RS232 port.
A block diagram of the communications subsystem is shown below.
A copy of the Xport Users Guide and the Lantronix DeviceInstaller program is included on the provided CD.
For detailed information regarding the setup and operation of the XPort™ Device Server, consult the Lantronix
documentation available at the Lantronix website www.lantronix.com
5-1.1 Operating Modes: The rear-panel RS232 port serves several functions, which are controlled via the 3-position
Mode Select Switch.
Serial Mode: This position allows the RS232 port to be directly connected to the serial port of the
8210A, effectively bypassing the XPort’s ability to control the unit via the Ethernet port. In this mode,
the serial port settings are controlled via the internal DIP switch of the 8210A.

Ethernet Mode: This position internally connects the serial port of the device server to the serial
port of the 8210A, allowing for network control of the unit. In this mode, the external serial port is
non-functional. The serial communication settings of the device server must be set to match that of
the 8210A for proper operation.
Console Mode: This position connects the RS232 port directly to the XPort device server. This
mode allows the setup/configuration of the device server to be performed via the RS232 port. In this
mode, serial communications are fixed at 9600 N81. For detailed information regarding operation,
refer to the Xport Users Guide Chapters 5-8 (Setup Mode) and Chapter 11 (Monitor Mode).
5-1.2 Serial Port Setup: By default, the unit is shipped configured for 9600 baud, no parity, and 1 stop bit, with no
handshaking required (9600N81). The rear-panel male DE-9 connector is configured as a DTE port (the same as a
typical PC) with the following pinout:
Pin Name Dir Description
2 RXD Receive Data (in)
3 TXD Transmit Data (out)
5 GND -- System Ground
Connection to another DTE device (ie a PC) requires the use of a null-modem cable to swap pins 2 and 3.
Communication settings for the 8210A are controlled via the internal Serial/GPIB Settings DIP switch located on the
board (refer to the 8210A Manual IM-288), while the XPort serial configuration is set independently and can be done
using a variety of methods. Refer to the Xport Users Guide for a detailed description of the available setup mode
methods and options.
NOTE
If you wish to change the serial port operation, keep in mind that the settings must match in both
places in order for the XPort to communicate successfully with the 8210A when used in the
Ethernet control mode.
5-1.3 Ethernet Setup: The network address of the XPort must be configured prior to use. There are several ways to
assign an IP address to the Xport. A general overview is provided here. For more detailed information and links to
video tutorials on performing many of these steps, refer to the information provided on the CD.
5-1.3.1 DeviceInstaller: The Lantronix DeviceInstaller is a Windows-based program that can be used to setup the
Xport. Of the methods presented here, this is the simplest. However, the DeviceInstaller relies on the Xport being set
for DHCP. If a static IP has been previously assigned to the Xport, there is a high probability that the DeviceInstaller
will not be able to see the Xport, especially if the IP or Gateway network settings do not match that of the PC currently
being used. If that is the case, you will have to use one of the other methods outlined below.
To use the DeviceInstaller utility, first install it from the product CD or click on the link below to download the latest
version of DeviceInstaller.

Assigning an IP Address in DeviceInstaller
a. Click Start->Programs->Lantronix->DeviceInstaller->DeviceInstaller. If your PC has more than one network
adapter, a message displays. Select an adapter and click OK.
b. Click the Search icon and select the unit from the list of Lantronix device servers on the local network.
c. Click the Assign IP icon.
d. If prompted, enter the hardware address (on the product label) and click Next.
e. Select Assign a specific IP address and click Next.
f. Enter the IP address. The Subnet mask displays automatically based on the IP address; if desired, you may
change it. On a local network, you can leave the Default gateway blank (all zeros). Click Next.
g. Click the Assign button and wait several seconds until a confirmation message displays. Click Finish.
h. Select the device from the main window list and select Ping from the Tools menu. The Ping Device dialog box
shows the IP address of the selected unit.
i. From the Tools menu, click the Ping button. The results display in the Status window. Click the Clear Status
button to clear the window so you can ping the device again.
Note: If you do not receive “Reply” messages, make sure the unit is attached to the network properly and
the IP address assigned is valid for the particular network segment you are working with. If you are not
sure, check with your systems administrator.
j. Click the Close button to close the dialog box and return to the main window.
5-1.3.2 Serial Port Login: To assign the IP address and other network settings using a serial connection:
a. Connect a console terminal or a PC running a terminal emulation program to the rear-panel RS232 connector.
The default serial port settings are 9600 baud, 8 bits, no parity, 1 stop bit, no flow control. Set the rear-panel
Mode Select switch to the Console position.
b. To enter Setup Mode, cycle the unit's power (power off and back on). After power-up, the self-test begins and
the red Diagnostic LED starts blinking. You have one second to enter three lowercase ‘x’ characters.
Note: The easiest way to enter Setup Mode is to hold down the ‘x’ key at the terminal (or emulation) while
powering up the unit.
c. The display should be similar to:
MAC address 00204AC530DB
Software version V6.6.0.2 (080926) XPTEXE
Press Enter for Setup Mode
d. The Xport has a built-in timeout function, and you must press the ‘Enter’ key within three seconds to enter the
Setup Mode. If you do not, the Xport will timeout and display “?!?”, after which it will continue with the boot
process and you will have to repeat Step 2.
e. Select 0 (Server Configuration) and follow the prompts until you get to IP address.
f. Enter the new IP address, subnet mask, and gateway (if applicable).
g. Select 9 to save and exit Setup Mode. The unit performs a power reset.

5-1.3.3 ARP and Telnet: If a serial port is unavailable, you can use the Address Resolution Protocol (ARP) method
from UNIX and Windows-based systems to assign a temporary IP address.
To assign a temporary IP address:
a. On a UNIX or Windows-based host, create an entry in the host's ARP table using the intended IP address and
the hardware MAC address of the Xport, which should be available on the rear-panel of the unit. Make sure
that the intended IP is reachable with the current network settings of the host. The following example uses an
IP of 192.12.3.77. Substitute the desired address in it’s place, and the MAC address of the Xport in place of
the 00:20:4a:xx:xx:xx
arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)
arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)
b. Open a Telnet connection to port 1. The connection fails quickly, but the unit temporarily changes its IP
address to the one designated in this step.
telnet 191.12.3.77 1
c. Open a Telnet connection to port 9999, and press Enter within three seconds to go into Setup Mode. If you
wait longer than three seconds, the unit reboots and you will have to repeat Step 2.
telnet 191.12.3.77 9999
d. Select 0 (Server Configuration) and follow the prompts until you get to IP address.
e. Enter the new IP address, subnet mask, and gateway (if applicable).
f. Select 9 to save and exit Setup Mode. The unit performs a power reset.
5-1.3.4 DHCP: The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP
server exists on the network, it provides the unit with an IP address, gateway address, and subnet mask when the unit
boots up.
The DeviceInstaller software can be used to search the network for the DHCP assigned IP address and add it to the
list of devices retrieved.
NOTE
This DHCP address does not appear in the unit’s Setup Mode or in Web Manager. You can
determine your unit’s DHCP-assigned IP address in Monitor Mode. When you enter Monitor Mode
from the serial port with network connection enabled and issue the NC (Network Communication)
command, you see the unit’s IP configuration.
5-1.3.5 AutoIP: The unit ships with a default IP address of 0.0.0.0, which automatically enables Auto IP within the
unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address automatically in smaller networks that
may not have a DHCP server. A range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been explicitly
reserved for AutoIP-enabled devices. Do not use this range of Auto IP addresses over the Internet.
If your unit cannot find a DHCP server, and you have not manually assigned an IP address to it, the unit
automatically selects an address from the AutoIP reserved range. Then, your unit sends out a (ARP) request
to other nodes on the same network to see whether the selected address is being used.
If the selected address is not in use, then the unit uses it for local subnet communication..
If another device is using the selected IP address, the unit selects another address from the AutoIP range and
reboots. After reboot, the unit sends out another ARP request to see if the selected address is in use, and so
on.

AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the network. If it finds a DHCP
server, the unit switches to the DHCP server-provided address and reboots.
NOTE
If a DHCP server is found, but it denies the request for an IP address, the unit does not attach to
the network, but waits and retries.
AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but disables AutoIP.
5-1.3.6 BOOTP: Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific
duration of time.
5-1.3.7 Device Server Setup: The Channel Configuration section of the Setup Mode is used to define how the serial
port responds to network and serial communications when operating as a device server. See the Xport Users Guide
Chapter 7 (Setup Mode: Channel Configuration) section for more details on each of these entries. Some of the
important settings in this section are:
Baudrate: This is the baudrate used by the Xport to communicate to the 8210A when in device server
mode. This setting must match the rate used by the 8210A, and is typically 9600.
I/F (Interface) Mode: The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation.
This setting controls the serial port settings of the device server, such as number of bits, parity, stop
bits, etc. The default value for this parameter is 4C, which specifies RS-232C, 8-bit, No Parity, 1 stop
bit.
Flow: Flow control sets the local handshaking method for stopping serial input/output. The default
setting for this parameter is 00 (no flow control)
Port Number: The setting represents the source port number in TCP connections. It is the number
that is used to establish a connection via the network interface. The default setting for this parameter is
10001. This number may have to be changed to match the user’s software. Certain ports are reserved
and should not be used. Refer to the section in the Xport Users Guide for a detailed list.
Compatibility note: units previously mfg’d using the Lantronix MSS-LITE were set to communicate via
port 3001
Connect Mode: Connect Mode defines how the unit makes a connection, and how it reacts to
incoming connections over the network. Enter Connect Mode options in hexadecimal notation. The
default setting is C0, which sets the following options:
Incoming Connection - Always Accept
Response - Nothing (quiet)
Active Startup - No active startup
5-1.3.8 Example Setup Using The Serial Port:
a. Set the rear-panel MODE SELECT switch to CONSOLE position.
b. Open a terminal emulator. Set the PC serial port for 9600N81, no flow control. Serial port cable connections
to a PC will require the use of a null-modem cable (DTE to DTE device).
c. To access the Xport SETUP mode, you must enter three lowercase 'x' characters within one second after
powering on the unit. The easiest way to enter Setup mode is to hold down the 'x' key, and power up the unit.
d. Response should be::
MAC address 00204AC530DB
Software version V6.6.0.2 (080926) XPTEXE
Press Enter for Setup Mode
