Socket Port Configuration

This section discusses the following topics:

• SocketServer Overview

• SocketServer Versions

• Accessing Socket Configuration

SocketServer Overview

SocketServer is the name of the TCP/IP socket web page that is integrated in the
firmware that comes pre-installed on your DeviceMaster 500.

If you want to use any of the ports as COM or tty ports, you should first install and
configure the NS-Link device driver for your operating system, and then configure
the ports that you want to use as TCP/IP sockets. When you install an NS-Link
device driver, an NS-Link version of SocketServer loads on the DeviceMaster 500.
See Device Driver Installation

The main SocketServer web page provides access to configure:

• Socket port characteristics for:

• Network settings (after initial configuration)

• Email notification services

• RFC1006 (ISO over TCP)

Note: For socket service configuration procedures, see the web page Help system or

64 - Troubleshooting and Technical Support DeviceMaster 500 User Guide: 2000501 Rev. A

Troubleshooting and Technical Support

General Condition Explanation/Action

The NS-Link driver uses Port 4606 (11FE h) to
communicate with the DeviceMaster 500.

Can ping the Comtrol
device, but cannot open
the ports from a remote
location.

(You must have
previously programmed
the IP address, subnet
mask, and IP gateway.)

When using a “sniffer” to track NS-Link packets,
filtering for Port 4606 will easily track the packet. The
packet should also contain the MAC address of the
device and the originating PC so that it can be
determined if the packet is able to travel the full
distance one way or not.

If the 4606 packet is found on one side of a firewall or
router, using sniffer, and not on the other side, then that
port needs to be opened up to allow the 4606 to pass.

This will most often be seen with firewalls, but is also
seen in some routers.

Cannot ping the device
through Ethernet hub

Isolate the DeviceMaster 500 from the network.
Connect the device directly to the NIC in the host
system (see Page 63).

The default IP address is often not accessible due to the
subnet masking from another network unless 192.168 is
used in the network.

In most cases, it will be necessary to program in an

Cannot ping or connect

address that conforms to your network.

If you do not use the NS-Link driver to program the IP
address, you only have 15 seconds to disable the
Bootloader with Redboot to get into the setup utility.

See RedBoot Procedures

on Page 49 for the Redboot

method of programming an IP address.

DeviceMaster 500 User Guide: 2000501 Rev. A Troubleshooting and Technical Support - 65

Troubleshooting and Technical Support

General Condition Explanation/Action

DeviceMaster 500
continuously reboots
when connected to some
Ethernet switches

DeviceMaster 500
continuously reboots
when connected to some
Ethernet switches or
routers

The problem is caused by a L2 bridging feature called
Spanning Tree Algorithm (STA) in the Switch. This
feature is enabled by default in some switches. This
features causes time-out problems on certain L2
protocols, such as our MAC mode.

Resolution: There will be no firmware fix for this
problem. Only one of the following fixes is required for
resolution.

1. Disable STA in the switch.

2. Enable STA fast forwarding on the port.

3. Change the STA Forward Delay and Message Age to
minimum time values.

4. On the device, set the time-out value to 0 (to disable
loading of SocketServer) or 120. The command from
the redboot prompt is “Timeout 120” without the
quotes.

Problem Details: STA by default blocks packets for 30
seconds after an ethernet port auto negotiates. Blocking
of these packets causes the NS-Link driver load process
to fail.

The normal NS-Link load process is:

1. If NS-Link determines that it needs to load a device,
it resets the device. It does this to get the device into
Redboot mode. Only Redboot accepts “load binary”
commands, which are needed to load the NS-Link
binary into the device.

2. After a 6 second delay, NS-Link sends an ID query
to the device. This query is to verify that the device
is in Redboot and can accept “load binary”
commands.

3. The device sends an ID query response.

4. NS-Link loads the device.

If the device is not loaded after “timeout” seconds
(default 15), it loads SocketServer.

The above process fails when STA is running because
the switch blocks packets for 30 seconds after the RTS
is rebooted. Therefore, the ID query is not received by
the RTS and after 15 seconds the device loads
SocketServer. After 30 seconds, NS-Link finally can do
an ID query, which reveals that the device is not in
Redboot. NS-Link therefore reboots the device, and the
process repeats.

Invalid IP information may also cause the switch or
router to check for a gateway address. Lack of a
gateway address is a common cause.

Daisy-Chaining DeviceMaster 500 4-Port Units

The DeviceMaster 500 4-port models with external power supplies follow the
IEEE specifications for standard Ethernet topologies.

When using the UP and DOWN ports, the DeviceMaster 500 4 is classified as a
switch. When using the UP port only, it is a simple end node device.

The maximum number of daisy-chained DeviceMaster 500 4 units, and the
maximum distance between units is based on the Ethernet standards and will be
determined by your own environment and the conformity of your network to these
standards.

Comtrol has tested with seven DeviceMaster 500 4 units daisy-chained together
using 10 foot CAT5 cables, but this is not the theoretical limit. You may experience
a performance hit on the devices at the end of the chain, so it is recommended that
you overload and test for performance in your environment. The OS and the
application may also limit the total number of ports that may be installed.

Following are some quick guidelines and URLs of additional information. Please
note that standards and URLs do change.

• Ethernet 10BASE-T Rules

- The maximum number of repeater hops is four.

- You can use Category 3 or 5 twisted-pair 10BASE-T cables.

- The maximum length of each cable is 100m (328ft).

Note: Category 3 or 5 twisted pair cables look the same as telephone cables

but they are not the same. The network will not work if telephone
cables are used to connect the equipment.

• Fast Ethernet 100BASE-TX rules

- The maximum number of repeater hops is two (for a Class II hub). A Class
II hub can be connected directly to one other Class II Fast Ethernet hub. A
Class I hub cannot be connected directly to another Fast Ethernet hub.

- You must use Category 5 twisted-pair 100BASE-TX cables.

- The maximum length of each twisted-pair cable is 100m (328ft).

- The total length of twisted-pair cabling (across directly connected hubs)
must not exceed 205m (672ft).

Note: Category 5 twisted pair cables look the same as telephone cables but

they are not the same. The network will not work if telephone cables
are used to connect the equipment.

• IEEE 802.3 specification: A network using repeaters between communicating
stations (PCs) is subject to the “5-4-3” rule of repeater placement on the
network:

- Five segments connected on the network.

- Four repeaters.

- Three segments of the 5 segments can have stations connected. The other

two segments must be inter-repeater link segments with no stations
connected.
