E5810B Software/Firmware Descriptions

E5810B operating features

Remote access to connected instruments via LAN

The E5810B allows access and control of up to 14 GPIB instruments, 4 USB instruments via a self-powered hub, and one RS-232 instrument via a 10BASE-T/ 100BASE-TX /1000BASE-T Ethernet. The E5810B detects the network and configures itself to the appropriate speed. The E5810B has a standard RJ-45 LAN connector.

I/O software

The E5810B includes the Keysight IO Libraries Suite, which includes Keysight Virtual Instrument Software Architecture (VISA), VISA COM, Standard Instrument Control Library (SICL), and several I/O utilities.

This standard software provides compatibility with different hardware and software vendors. It provides the I/O software layer used when accessing the E5810B. You can use a standard programming language, such as C/C++, Visual Basic, and Keysight VEE.

The E5810B supports all I/O application operations provided by VISA, VISA COM, SICL, and Keysight VEE. The E5810B is supported on Microsoft Windows XP, Windows Vista, Windows 7, Windows 8, Windows Server 2008 R2, and Windows Server 2012.

Supports DHCP protocol

The E5810B supports Dynamic Host Configuration Protocol (DHCP) to obtain the IP address. By default, DHCP is turned on. DHCP can be turned off and the E5810B can be assigned with a static IP address.

Web access

The E5810B is built in with Web access. The front panel display allows you to easily set up, configure, and use the E5810B. You can connect multiple E5810B in a test system. Each E5810B creates a separate GPIB bus.

26 Keysight E5810B User’s Guide

Typical network operation

The E5810B enables you to obtain measurement data either locally or remotely from GPIB, USB, and RS-232 instruments. Refer to “Typical network connections” on page 23 for the typical connections to a PC, a local network, or an Enterprise network.

The E5810B connects a LAN from the computer system to the GPIB, USB, and RS-232 buses. Using the client-server model of computing, the computer system is the client, and the E5810B is the server.

Applications running on the computer system can transparently interface to the GPIB, USB, and RS-232-based instruments over the LAN. Since several computer systems can access the E5810B, groups of users can share access to the same GPIB, USB, and RS-232 instruments via the E5810B.

Existing I/O applications that are supported with the E5810B and are designed for GPIB, USB, and RS-232 instruments can be used with the E5810B without any modification other than changing the IP address.

The E5810B and the connected instruments can be placed anywhere on the network (rather than with a particular controller or a server computer system). This includes networks which span different geographic locations, such as when networked computer systems are located at several different sites.

E5810B Description 1

GPIB, USB, and RS-232 instruments can be located where they are most convenient. You can also have more than one E5810B on a network, providing clusters of GPIB, USB, and RS-232 instruments at different locations.

The VISA LAN client software, and TCP/IP LAN software is needed on the client system (PC) to access the E5810B as shown in Figure 1-6. The E5810B consists of the LAN server and TCP/IP LAN firmware, so that the E5810B can perform as the

28 Keysight E5810B User’s Guide

LAN server.

The VISA LAN client software is also known as the Remote IO Client software. It is part of Keysight IO Libraries Suite. The LAN server software is also called the Remote IO Server software.

The VISA LAN client software uses the TCP/IP LAN protocol suite to pass messages between the client system and the server (E5810B). The client sends I/O requests over the network to the server. The server will executes those I/O requests on the appropriate GPIB, USB, and RS-232-based instruments connected to the server.

E5810B Description 1

I/O application operation

Before performing an I/O application operation on the E5810B GPIB, USB, or RS-232 interface and the GPIB, USB, or RS-232 bus, the Remote IO Client software in the client computer system must establish a network connection to the remote I/O server (E5810B). Once the client establishes a connection, the client can begin to send I/O requests to the E5810B.

The E5810B (remote I/O server) allows multiple clients to be connected and serviced at any given time. The maximum number of concurrent client connections depends on the memory usage in the E5810B, including the number of clients and current sessions running on those clients. However, the E5810B only allows up to 16 client connections to be run concurrently.

If the maximum number of client connections to the E5810B has not been exceeded, the connection is allowed. Although several instruments can be connected to the E5810B GPIB bus, only one I/O application operation can be performed on the GPIB bus at any given time. Therefore, once a client’s request begins to execute on the GPIB, all other client requests for operations on the GPIB must wait until the current client request completes. Client requests are serviced in a first come, first served manner, unless they are prohibited by the interface or the device locks.

If a client has a sequence of I/O application operations to perform that should not be preempted, the client should obtain a lock on the E5810B GPIB, USB, or RS-232 interface or device. Once the client’s sequence is completed, it should release its lock, allowing access for other clients.

When a client closes a connection, the E5810B frees up the resources allocated to that client, including any locks, pending I/O requests, and memory usage.

Typical network IP addressing

This section describes the typical Enterprise network IP addresses and subnet addresses on the network. Figure 1-7 shows a typical Enterprise network, consisting of a router (gateway), a corporate Dynamic Host Configuration Protocol (DHCP) server, and a subnet consisting of six hosts (two E5810Bs and four host PCs). The router sends packets of information to each host, based on the IP address of the host. The subnet is defined by the Subnet Mask for the IP addresses on the subnet.

Subnet addressing

30 Keysight E5810B User’s Guide

E5810B Description 1

A Subnet Mask is used to determine to which subnet an IP address belongs. An IP address has two components: the network address and the host address. For example, the IP address 156.215.117.109 is part of a Class B network. The first two numbers (156.215) represent the Class B network address and the second two numbers (117.109) identify a specific host on this network. Refer to “Glossary” on page 119 for more information on the Class B network.

For the subnet as shown in Figure 1-7, the IP address for E5810B #1 is

156.140.104.72, where 156.140 represents the network address and 104.72 represents the E5810B #1 host address. The IP address for E5810B #2 is

156.140.104.75, where 156.140 represents the network address and 104.75 represents the E5810B #2 host address.

IP address assignment

For the E5810B to operate on an Enterprise network, three addresses must be identified — E5810B IP Address, Subnet Mask, and Default Gateway Address.

If the Enterprise network supports Dynamic Host Configuration Protocol (DHCP), the E5810B will automatically receive an IP address, Subnet Mask, and Default Gateway from the DHCP server. If the network does not support DHCP, the E5810B IP address must be configured manually.

If the network supports Domain Name Service (DNS), the E5810B hostname can be configured. This can be done in two methods.

– The DNS server IP Address is provided by the DHCP server (this is transparent

to the user).

– A DNS server IP address is supplied by the system administrator and entered

on the Configuring your E5810B LAN/GPIB/USB Gateway page.

Turn on the E5810B and the IP address will be displayed on the front panel display.

– The E5810B may require up to 75 seconds to display the default static IP

address (169.254.58.10) as it will try to find a DHCP server until a timeout value is reached.

– If you try to simultaneously attach multiple E5810Bs without changing each

unit’s default static IP address, some E5810Bs may not be able to start operation. The E5810B detects duplicated IP addresses and will not start operation if the IP address is already in use.

– To prevent this, add a E5810B at a time and configure the E5810B to a unique

IP address before adding the additional E5810Bs.

2 Installing the E5810B

NOTE

Configuring the E5810B for a local network operation

This section provides the guidelines to configure the E5810B on a local network or eventual installation on a non-DHCP Enterprise network.

The first step in configuring the E5810B on a local network is to establish communication between your PC and the E5810B. The PC and the E5810B must be on the same subnet in order to establish a connection.

To place the PC and the E5810B on the same subnet, type in route add <E5810B IP address> <PC IP address> in the MS-DOS prompt program.

For example, if the PC IP address is 155.139.103.152 and the E5810B IP address is

169.254.58.10 (default), the commands are as follows:

!route is lost when the PC is rebooted route add 169.254.58.10 155.139.103.152

!route persists when the PC is rebooted route -p add 169.254.58.10 155.139.103.152

After the connection is established, you can set the required configuration parameters using the E5810B Web access.

Refer to Chapter 3, "E5810B Web Access" for more information in configuring the E5810B parameters using the E5810B Web access.

Programming instruments

After the communication between the PC and the remote interface instruments is established, you can program the remote interface instruments using Keysight VISA, VISA COM, or SICL to send instrument commands such as SCPI.

You can also program in various languages or applications, including Visual Studio .NET languages, Visual Basic, Visual C++, Keysight VEE, and National Instruments LabVIEW.

For general programming guidelines, refer to the documentation for your programming environment. You can also find programming examples using various I/O libraries and instrument drivers in the instrument’s User’s Guide. After the E5810B is successfully installed and configured, it should act as a transparent interface for programming GPIB, USB, and RS-232 instruments.

For more information on programming using Keysight VISA, VISA COM, or SICL, refer to the respective instrument’s User’s Guide. You can also refer to Keysight Connectivity Guide and Keysight IO Libraries Suite Help for further information and guidelines on programming with Keysight IO Libraries.

These documents can be obtained by clicking the IO icon on the Windows taskbar notification area and selecting Documentation.

Installing the E5810B 2

Addressing instruments using VISA and remote IO client

After you have created a remote GPIB, remote USB, or remote serial interface in Keysight Connection Expert, you can use ordinary GPIB, USB, or serial addressing in your VISA or VISA COM programs to address instruments on these interfaces.

The Remote IO Client software maps the TCPIP address requests into the appropriate interface type (GPIB or ASRL) addresses. Thus, the IP address and hostname of the E5810B do not appear in the instrument address. This makes it possible to use existing programs written for GPIB or ASRL without modifying code.

Keysight E5810B User’s Guide 57

2 Installing the E5810B

After the remote interface instruments are configured, VISA programs can then use addresses such as GPIB0::22::INSTR (for GPIB), USB::INSTR (for USB), or ASRL1::INSTR (for RS-232). Use these addresses in your viOpen() call as follows:

viOpen (..."GPIB0::22::INSTR"...) viOpen (..."USB0::INSTR"...) viOpen (..."ASRL1::INSTR"...)

Addressing instruments using VISA and TCPIP interface

Although remote GPIB, remote USB, and remote serial interfaces are the most convenient ways to configure and program instruments on your E5810B, you may choose not to use them. For example, if you are using another vendor’s I/O software rather than the Keysight IO Libraries Suite, your I/O software may not support remote interface addressing.

If you are not using remote interfaces, you will address your instruments as TCPIP resources in VISA. These addresses include the IP address or hostname of the E5810B as well as the SICL address of the device on the E5810B.

Use these addresses in your viOpen() call as follows. These examples assume that the VISA interface ID of your TCPIP interface is TCPIP0. (You can specify this interface ID with the Connection Expert utility; TCPIP0 is the default VISA ID for the default TCPIP interface.)

viOpen (..."TCPIP0::my_IP_address::gpib0,22::INSTR"...) viOpen (..."TCPIP0::my_IP_address::usb0::INSTR"...) viOpen (..."TCPIP0::my_IP_address::COM1,488::INSTR"...)

Addressing instruments with SICL

SICL addresses include the IP address or hostname of your E5810B as well as the SICL address of the device on the E5810B, and optionally the protocol to be used. Some example addresses for SICL programs are as follows. These examples assume that the SICL interface ID of your TCPIP interface is “lan”. (You can specify this interface ID with the Connection Expert utility. The default SICL ID for TCPIP0 interface is “lan”.)

lan[my_IP_Address]:gpib0,22 lan;vxi-11[my_IP_Address]:gpib0,22 lan[my_IP_Address]:usb0

NOTE

lan;vxi-11[my_IP_Address]:usb0 lan[my_IP_Address]:COM1,488 lan;sicl-lan[my_IP_Address]:gpib0,11

At the time of writing, National Instruments I/O software does not support the SICL-LAN protocol, but only the VXI-11 protocol. As the RS-232 instruments are only supported by SICL-LAN and not VXI-11, you are not able to use National Instruments I/O software to program an RS-232 instrument on your E5810B.

IP Address 169.254.58.10 The Internet Protocol (IP) address of the E5810B is a required value

and is used for all IP and TCP/IP communications with the E5810B. The IP address is represented in dotted decimal notation (for example, 154.140.222.201). This number is assigned by the system administrator.

LAN traffic to the E5810B will be routed by the IP address or by using a hostname that may be provided by a DNS name server which is mapped to this IP address. The current E5810B IP address may have been established in one of these two methods:

– The IP address was provided by a DHCP server during startup

(dynamic IP address).

– The IP address shown on the Current Configuration of the

E5810B LAN/GPIB/USB Gateway page was used. This was set by default to 169.254.58.10. If DHCP is not used, the IP address should be set for your network.

Subnet Mask 255.255.0.0 Subnet mask is used to enable the E5810B and determine if a

client’s IP address is on the same local subnet as the E5810B. When a client’s IP address is on a different subnet, all packets must be sent to a subnet gateway.

Refer to Glossary for an example of a subnet.

Default Gateway 0.0.0.0 The default gateway is the IP address of the default subnet gateway

that allows the E5810B to communicate with systems that are not on the local subnet. This is the default subnet gateway where packets are sent to a device not on the local subnet, as determined by the subnet mask setting. Only one default subnet gateway can be configured. A value of 0.0.0.0 indicates that no subnetting is configured.

Parameter Defaul t setting Description

Domain Name Server (DNS) 0.0.0.0 A DNS server is an Internet service that translates domain names

into IP addresses. Every time you use a domain name, a DNS server will translate the name into the corresponding IP address. For example, the domain name www.example.com might be translated to 198.105.232.4.

The DNS system has its own network. If one DNS server does not know how to translate a particular domain name, it will ask another DNS server. For example, a DNS server will ask until the correct IP address is returned, if it is available.

If DHCP is used, a DHCP server may provide a DNS server IP address to the E5810B (this is transparent to the user). If you configure a DNS server, the E5810B will try to use that server first.

This parameter shows the IP address of the domain name server. More than one address may be listed on the Current Configuration of the E5810B LAN/GPIB/USB Gateway page. Up to two of these values may have been returned by the DHCP server during startup. Only one static value can be inputted on the Configuring your E5810B LAN/GPIB/USB Gateway page.

The DNS server provides a hostname, given that the IP address for a LAN device is based on entries in its DNS lookup table. If DHCP is turned off, and you do not specify a DNS server or if a dynamic DNS is not available on your enterprise LAN, and your IP address is not in the DNS lookup table on the DNS server, your hostname will be unknown and you must address the E5810B only by the IP address. The hostname is not a required configuration value.

Table 3-1 E5810B configuration parameters description (continued)

Parameter Default setting Description

Hostname None The hostname configures the Internet domain name for the

E5810B. Hostnames are useful when IP addresses are being assigned by a DHCP server, since the hostname will not change when the DHCP server or the device IP address changes.

If a hostname is entered, the E5810B will try to register this name when it boots up. The E5810B can only register the hostname if the network has a dynamic DNS. If the network does not have dynamic DNS, this value is not used. Because you can always use the IP address or the name (possibly supplied by another name server), the hostname is not a required configuration value.

You may enter up to 35 characters for the hostname. The hostname must start with a letter, and it consists of upper and lower case letters, digits, and dashes. There is no default hostname. If a hostname is displayed on the Welcome page, it is a valid hostname as one was found on the network through the DNS.

Description Factory-set The default description consists of E5810B followed by the

Ethernet (MAC) address. The Ethernet (MAC) address is printed on a label at the bottom panel of the E5810B.

A typical description is Keysight E5810B 00-30-D3-05-00-23, where 00-30-D3-05-00-23 is the Ethernet (MAC) address. The description is the UPnP Friendly Name of the E5810B that will automatically be displayed on Universal Plug and Play (UPnP) enabled LAN hosts.

When the E5810B is connected to the LAN, it broadcasts its presence to the network if UPnP is enabled. UPnP clients will see the E5810B in My Network Places, listed by this description. A Friendly Name can be up to 39 characters, including spaces.

Tab le 3-1 E5810B configuration parameters description (continued)

Parameter Defaul t setting Description

Universal Plug & Play [UPnP] ON If Universal Plug & Play (UPnP) is enabled, a multicast message is

generated and sent about once an hour to the subnet. Enterprise networks will want to decide whether this additional traffic is acceptable. By default, UPnP is not enabled. Check your operating system instructions to enable UPnP.

– UPnP ON:

The E5810B is configured as a UPnP device and provides information to the network about itself via an XML description when mounted to the network.

– UPnP OFF:

The E5810Bis not UPnP capable and will not announce its presence as a UPnP device when mounted to the network.

LAN Keepalive 7200 seconds The LAN keepalive value sets the LAN connection timeout in

seconds. The E5810B may use the TCP keepalive timer of the TCP/IP protocol stack to determine if a client is still reachable. By specifying this configuration value, the E5810B turns on the keepalive timer when connecting to the client.

After a specified time, if there is no activity on the connection, the E5810B sends keepalive probes to the client to determine if it is still alive. After the specified amount of time, the connection will be marked as down or dropped, and the E5810B will release any resources that were allocated to the associated client.

A value of 0 means no timeout is set. The E5810B will wait forever and no keepalive probes are sent. If this value is set, it is recommended that the largest value be used which will still meet the application’s need for unreachable client detection.

Smaller LAN keepalive values will generate more keepalive probes (network traffic), using more of the available network bandwid th. Allowable values are 0 and greater than or equal to 600 seconds (10 minutes).

Table 3-1 E5810B configuration parameters description (continued)

Parameter Default setting Description

I/O Timeout 120 seconds The I/O timeout value sets the server I/O timeout in seconds. It

configures the E5810B to use an I/O timeout of the specified amount of seconds if a client requests a timeout of infinity. If 0 is specified for this value and the client requests an infinite timeout, the E5810B will use a timeout of infinity as requested.

Setting the I/O timeout to 0 is not recommended, as this can result in the E5810B waiting indefinitely for an I/O operation and effectively stall the E5810B.

This timeout value may be used to ensure that the E5810B does not wait indefinitely for an I/O operation. It also allows the E5810B to detect certain network events that may go undetected, such as when a client’s connection is dropped. If the E5810B detects this condition, it will release any resources, such as locks which are associated with the client.

GPIB SICL Interface Name gpob0 The GPIB SICL interface name is the symbolic name of the GPIB

interface in the E5810B. It is used in an SICL client application’s iopen operation to symbolically reference the GPIB interface in the E5810B.

The maximum length of the GPIB interface name is 15 characters. If VXI-11 (TCP/IP Instrument Protocol) is used, the name must be gpib<n>. The names hpib or hpib7 may be used to support legacy programs, if only SICL/LAN protocols are used.

GPIB Address 21 The GPIB address is the GPIB bus address of the E5810B. This

address is used when transfers are made on the GPIB bus. An SICL client application can change this value by using the SICL

function IGPIBBUSADDR. The GPIB address value can be any number from 0 to 30.

GPIB Logical Unit 7 The GPIB logical unit is the interface logical unit (LU) number of the

GPIB interface in the E5810B. It may be used in a Keysight SICL client application’s iopen statement to uniquely identify the GPIB interface in the E5810B.

The GPIB logical unit value can be any number from 1 to 255.

Button Description

Device Clear Sometimes communication with an instrument may be impeded. This can occur for a

wide variety of reasons. Sending a Device Clear command to the instrument usually solves this problem and restores proper communication with the instrument. If you encounter an error while performing a formatted I/O operation, send a Device Clear command to ensure a proper instrument communication is restored.

*IDN? (ID string) Returns the ID string for the selected IEEE-488.2 compliant instrument.

Read STB (Read Status Byte) Returns the decimal and hexadecimal value of the IEEE-488.2 compliant

instrument's status byte. Many instruments that support formatted I/O also have the ability to read the status byte. This command returns the information on the status of the instrument, such as error status and busy status. See your instrument manuals for the status byte codes.

SYST:ERR? (System error) Returns a SCPI system error for a SCPI compliant instrument. A return, 0 No errors

is sent to show no system errors.

Clear History Clears the display of all previous queries.

Clear ALL Pending Operations Clears all pending operations on instruments connected to the E5810B. This

operation expires all existing timeouts on all the devices connected to the E5810B. Taking this action may affect other users currently using the E5810B. A password dialog box will appear that prompts you to confirm this action.

Timeout A timeout value is used to limit the amount of time for an I/O operation to complete.

The I/O timeout value, as set on the Configuring your E5810B LAN/GPIB/USB Gateway page, may not be long enough for some instrument activities to complete. Setting a longer timeout will inform the E5810B to wait a longer time for the instrument to finish.

Alternatively, sending a separate Send and Receive command may also work. If the configuration value is too long, you may also force a shorter timeout here for faster troubleshooting of the instrument tests. To set a different timeout, enter a timeout value in the Timeout text box. This value is used for all commands issued to an instrument from this page. The valid timeout range is 1 to 60 seconds.

4 Troubleshooting the E5810B

Checking the Web browser settings

The E5810B Web access generates Web pages that depend on Javascript and Frames. For best results, you will need to enable the Javascript, and configure the Cache and Page Refresh, and Proxies settings on your Web browser.

Enable Javascript (Internet Explorer 6 or greater)

If the E5810B detects that Javascript is not enabled, a dialog box will pop-up on the E5810B Welcome page displaying the instructions to enable Javascript on the Web browser.

If Javascript is not enabled, you will not be able to view the View and Modify Configurations page or the Find and Query Instruments page.

Use the following procedure to enable Javascript.

1 Select Tools > Internet Options from the Internet Explorer menu.

2 Select the Security tab.

3 Select Custom level... under Security level for this zone to display the Security

Settings dialog box.

4 Under Settings, scroll down to the Scripting category.

5 Select the Enable check box under Active Scripting.

6 Select the Enable check box under Scripting of Java applets.

7 Select OK to accept the security settings.

8 Follow the instructions as prompted to save the settings.

Cache and Page Refresh (Internet Explorer 6 or greater)

Typically, Web browsers cache Web pages to store an image of the Web page locally. When you navigate to an already viewed page, the page is loaded from the cache rather than from the network. This is acceptable for static Web pages in which the information does not change.

However, the E5810B uses dynamic Web pages in which the information are dynamically updated.

To avoid displaying outdated information on the Web pages, set the Check for newer versions of stored pages to Every visit to the page or a similar option on your Web browser.

98 Keysight E5810B User’s Guide

Troubleshooting the E5810B 4

Use the following procedure to configure the Cache and Page Refresh settings.

1 Select Tools > Internet Options from the Internet Explorer menu.

2 Select the General tab.

3 Select Settings under Browsing history to display the Settings dialog box.

4 Select the Every time I visit the webpage check box under Check for newer

versions of stored pages:.

5 Select OK to accept the settings change.

Proxies (Internet Explorer 6 or greater)

If you are using a proxy server, the Web page may time-out even though the correct IP address or hostname is entered into the Web browser.

To avoid this, the Web browser must be informed that any requests to the E5810B should not use a proxy. Add the IP address of the E5810B to the list box at Do not use proxy server for addresses beginning with: or a similar option on your Web browser.

Use the following procedure to set the proxy notification.

1 Select Tools > Internet Options from the Internet Explorer menu.

2 Select the Connections tab.

3 Select LAN Settings under Local Area Network (LAN) settings.

4 Select Use a proxy server for your LAN check box if it is not checked under

Proxy server and select Advanced.

5 Under Exceptions, add the IP address of the E5810B or a fully qualified domain

name (such as myE5810B.example.com) to the Do not use proxy server for addresses beginning with: box. Use a semicolon ';' to separate the entries.

6 Select OK to save the settings.

4 Troubleshooting the E5810B

NOTE

Checking other network problems

E5810B operation hangs

The E5810B has a single remote IO server servicing the GPIB, USB, and RS-232 interfaces. If one of the interface hangs in an operation where a timeout has been set to a long time period, there is no more communication on the interface until the pending transaction completes (via normal completion, or a timeout). That is, a pending operation on the RS-232 interface will stall the GPIB or USB operations, and vice-versa.

To avoid this, set a short timeout for the GPIB, USB, and RS-232 interfaces, so that the E5810B is not left in a hung situation awaiting a pending I/O operation. For example, a detached or loose GPIB, USB, or RS-232 cable can cause an operation to stall if timeouts are set too high.

Setting long timeouts with the E5810B is not recommended. However, if a long timeout period is required for your programming application, you can set the timeout with these commands:

VISA: viSetAttribute() and VI_ATTR_TMO_VALUE attribute

SICL: itimeout()

Refer to the Keysight VISA User’s Guide and the Keysight SICL User’s Guide for a description of the VISA command and SICL command respectively.

SICL timeout is set to 0 (infinite)

The E5810B uses the LAN maximum timeout configured in Keysight Connection Expert’s LAN interface for its default or infinite timeout. If an SICL itimeout(id,0) command is used (where a 0 timeout value is an infinite timeout) the E5810B will use the I/O Timeout (sec): value set on the Current Configuration of E5810B LAN/GPIB/USB Gateway page.

The default timeout value is 120 seconds. Setting the I/O Timeout (sec): value to 0 enables infinite timeouts from SICL applications.

It is highly not recommended to set an infinite timeout which can cause the E5810B to become unresponsive due to a pending operation that will never timeout.
