Intentional interruption of the grounding conductor is not permitted.
Chapter 1 Introduction Overview Description The Advance DataNET Hub (DNH) functions as a communication router on an Advance Communication System (ACS) network. The DNH is a fully redundant unit with dual electronics and with dual power supplies. The electronics are certified for use in NEC Division 2 and IEC (Cenelec) Zone 2 hazardous locations.
Overview, Continued The Advance DataNET Hub (DNH) is available in three package configurations: Package Configurations • 19-inch Rack Unit (Figure 1-5) • Wall Mount Unit (Figure 1-6) • Zone 1 Wall Mount Unit (Figure 1-7) The Advance Communication System (ACS) is a high-speed communications system that uses TCP/IP protocols and addressing to interconnect chromatographs and other process analyzers in a common network.
Overview, Continued A network of DataNET hubs forms a tree-like hierarchy. A DNH may connect to as many as eight “down-stream” devices (Maxum Analyzers or Advance Hub Uplink port). Each down-stream DNH, in turn, connects to another eight, and so on. No architectural limit is placed on the depth of the DataNET hub hierarchy. In practice, propagation time considerations and hub loading should allow hierarchies at least six or seven layers deep without incurring excessive timing delays.
DataNET Hub Operation DNH Links Figure 1-4 shows the individual links that connect three DataNET hubs and several end devices. The inter-hub links travel across twisted-pair copper or fiber-optic cables. The link data rate is 2.048Mbps for both cables. The DataNET hub software auto-detects the type of medium used on each DataNET port, and configures the hub accordingly. Each connection between a DataNET Hub (DNH) and another device consists of two links.
DataNET Hub Operation, Continued DataNET Switching DataNET switching operates by dynamically and automatically learning the topology of the network (i.e., which MAC/IP addresses are reachable through which paths) as Ethernet frames are forwarded through the network. The DataNET hubs require no static initialization of network data in order to perform their switching function. Each DNH can learn as many as 1200 IP addresses. This allows the hub to accommodate up to 1000 instruments (analyzers, etc.

AC Power (Mains) Connections DNH Power Supply Each of the DNH electronic modules has a Power Supply Assembly located below the DataNET Hub board. Each power supply can accept inputs from 85-264 VAC, 47-63 Hz without the need for setting switches or jumpers. AC INPUT CONNECTOR Installation Note Depending upon the user configuration the power supplies can be connected in parallel and powered from a single power source or each supply can be powered from two independent power sources.
AC Power (Mains) Connections, Continued Step 3. Action Install 15-Ampere circuit breakers, disconnect switches or receptacles in the incoming power supply lines or two switched receptacles near the DNH unit. This will ensure DNH power supplies will be completely separated from each of the power sources. Label the breakers or receptacle boxes to make sure that the circuits are clearly identifiable. Note: For one input power sources only a single breaker box or switch receptacle is required. 4.
AC Power (Mains) Connections, Continued Step 28 • Installation Action 7. Plug the connector back into its base and secure the two recessed captive screws. 8. If using redundant power supplies repeat steps 6 and 7. If not, use connecting wires to parallel connect to the other power supply. 9. and connect wire Locate the DNH chassis ground lug from it to the building’s ground connection. 10. Inspect all connections for shorts or loose connections. 11.
DataNET Copper Connections Description The DNH consist of two identical hubs in one enclosure. The left side is usually the DataNET ‘A’ Hub and the right side is the DataNET ‘B’ Hub. Each hub contains two DataNET Hub boards and power supplies. Figure 2-1 shows the layout of the DataNET Hub board. All port connections are made to the port connectors located on each communication board. The DataNET ports can accept copper and/or fiber optic cables.
DataNET Copper Connections, Continued See Figure 2-1. Each DataNET Hub board has nine DataNET ports. One of the DataNET ports is dedicated to ‘uplink’ connections, which will always be to another DNH. The uplink port (Port 9) is an uplink port while the other ports (Port 1 through 8) are downlink ports. DataNET Ports Note that each of the four Downlink Port connectors contains wiring connections for two DataNET port channels.
DataNET Copper Connections, Continued Cable Impedance Settings Behind each single port connector is an associated jumper pin block, see Figure 2-1. Each block is used to select the termination impedance of its associated port to match the cable’s own impedance characteristics. The three selections for each port are 100-ohm, 120-ohm and 150-ohm. Use the 150-ohm setting for the recommended cable. If the specific cable impedance is not known use the 100 ohm setting.
DataNET Copper Connections, Continued Down Link Wiring with DataNET Hub Signal Equalizer Board Step Action 1. Plug the DataNET Hub Signal Equalizer Board into the selected Port interface connector. 2. Connect the board’s pig tail leads to the corresponding hub downlink port channel; red lead to (+) terminal, black lead to (-) terminal and white lead to Gnd terminal. See Figure 2-1. Master Port Connectors TB15 – TB18 3.
DataNET Copper Connections, Continued Downlink Wiring without Signal Equalizer Board Each of the four downlink connectors (TB15, TB16, TB17, TB18) contain wring terminals for two downlink ports; see Figure 2-1. + Important Always ensure that the same port number is used for redundant channel connections i.e. Channel A to Port 1 on ‘A’ Hub and Channel B to Port 1 on ‘B’ hub. Step 1. Action Connect the downlink signal wires to a hub downlink port. Positive to (+) terminal; and Negative to (-) terminal.
DataNET Hub Signal Equalizer Board Description This section sets the switches on the DataNET Hub Signal Equalizer board. This board is used to equalize the signal amplitude when varying lengths of copper cable are connected to multiple downlink ports on the DNH. Typically the smallest signal on any DNH port is found on the port with the longest copper cable.
DataNET Hub Signal Equalizer Board, Continued Switch Setting for Unknown Cable Lengths When cable lengths are unknown, or the cable is other than the recommended cable (Table 2-1.), signals must be compared at the Hub to identify which Equalizer board settings are needed. See page 37. Switch Settings for Known Cable Lengths If the lengths of copper cable exceed those shown in Table 2-2, follow this procedure. See sample calculations page 36.

Signal Equalizer Settings for Non Recommended Cable or Unknown Cable Lengths Description This section is used to set the switches on the DataNET Signal Equalizer Board. If: • • the type copper cable used for port connections is other than the recommended cable the length of the cable runs are not known. Before You Begin Read the section on the DataNET Hub Signal Equalizer Board (page 34) as a prerequisite to this section.
Signal Equalizer Settings for Non Recommended Cable or Unknown Cable Lengths, Continued View Measurements Signals are viewed with an oscilloscope. Scope characteristics: 10 MHz bandwidth capable of measurement sensitivity of 0.2 v/div to 1.0 V/div. A typical two-channel scope can be employed using the channel 1 - channel 2 capability. Use X10 probes to reduce the loading of signals. Option 1.
Signal Equalizer Settings for Non Recommended Cable or Unknown Cable Lengths, Continued Instructions & Examples This procedure is for determining the DataNET Signal Equalizer Board settings for other than the recommended cable or if the cable run lengths are unknown. Step 1. Action To determine appropriate settings for attenuator boards, begin by measuring signal levels at the various ports (use either Option 1 or 2). Important The cables should be removed from all but one port at a time.
Signal Equalizer Settings for Non Recommended Cable or Unknown Cable Lengths, Continued Step 3. Action Examine the recorded signal levels and determine the dB loss for each port; refer to Table 2-2. Example: With these signal levels, port 4 is the lowest level, so no attenuation is required. Its signal level becomes the reference for comparing the remaining ports’ signal levels. The next strongest signal is on port 1. 1.6/1.25 = 1.28 20 log 1.28 = 2.1 dB or ratio of 1.
Signal Equalizer Settings for Non Recommended Cable or Unknown Cable Lengths, Continued Step 3. cont . Action The next strongest signal is on port 6. 4.8/1.25 = 3.84 20 log of 3.84 = 11.7 dB or ratio of 3.84 Since this signal is 11.7 dB stronger than the signal on port 4, the attenuator board on port 6 needs to be set to selection 5 (11 dB loss). This should put this signal at about 0.7 dB above the signal on port 4. (Selection 6 could also be used for 12.
DataNET Fiber Optic Connections Description All DataNET Fiber Optic uplink and downlink port connections are made through the DataNET Fiber Optic Coupler. The coupler PC card plugs into any of the port interface connectors to provide the same port flexibility as with copper cable connections; eight DataNET ports, one uplink port and one Ethernet 10BaseT port for interconnecting of DataNET or Ethernet segments.
DataNET Fiber Optic Connections Fiber Optic Cable Type Duplex Fiber, 62.5/125 micron Port Connections 1. Plug the DataNET Fiber Optic Coupler board into the selected single Port board connector. 2. Connect the transmitter and receiver ports for the respective channel.
Ethernet Connections Description ETHERNET PORT The DNH consists of two identical hub modules in one enclosure. The left side is usually the DataNET ‘A’ Hub and the right side the DataNET ‘B’ Hub. Each hub contains a DataNET Hub board and power supply. The DNH connects to the Ethernet local area network via the RJ-45 STP connector located on DataNET Hub board. Each of the boards has an Ethernet connection. However, the DNH only the ‘A’ hub Ethernet port is active. Figure 2-4.
Ethernet Connections, Continued 10BASE-T Cable Requirements 1. The 10BASET data cable requires a minimum of two twisted pairs (transmit pair and a receive pair). The type wire used should conform to the AT&T D-inside wire (DWI & PDS), or IBM Type 3, or Category 3 or 5 data grade or equivalent specifications. 2. The maximum length of a 10BASET data cable can not exceed 328 feet (100 meters). Typically to increase the distance each DNH will connect to a hub or other type of repeater/medium converter. 3.

The dn command is also used to enable and disable software tracing inside the hub software. This is intended to provide a software debug facility. The form for these commands is: dn module on dn module off In order to collect software trace events in the log buffer, you must also give the command “events on.
Command Description, Continued “help” Command This command generates a simple list of available commands. “list” Command Enter the list command at any time from the Configuration Management interface to see event buffer messages. The list command has an internal current sequence number that is set to 1 each time a Configuration Management login occurs. The list command will show 21 messages each time it is entered, beginning with the current sequence number.
Command Description, Continued The event display gives a time-stamp, and an event description. All events other than frame-capture events are always shown as single lines. Captured frames may be summarized as single lines, or expanded into a multi-line display (see ‘validation timeout’ command). The user can view more than 21 messages by supplying a sequence number and list length: List message numbers 100 – 199 and update the current sequence number to 200.
Command Descriptions, Continued “logout” Command This command logs the user out of a session. The user must be logged out of the local device to login to a remote device. “netstat” Command This command may be used to display statistics for the DataNET section. If a link number is given, statistics are displayed for just that link. If no link number is given, summary statistics for all DataNET links are given.
Command Descriptions, Continued “test” Command This command places a selected port into a hardware diagnostic mode. The command test 4 places port 4 into test mode. The hub will generate poll messages on port 4. All other ports continue to operate normally. The command test off turns off test mode. Only one port at a time may be in test mode. “timeout” Command 2000585-001 This command may be used to disable the user login timeout.
Command Descriptions, Continued “trace” Command The trace command controls the hub’s frame tracing function. This feature captures network messages sent and received by the hub-half in that hub-half’s event buffer. The trace command controls which messages are captured in the event buffer. Trace messages may be collected for the Ethernet port, the cross-link port, any of the 8 downstream ports or the single upstream port.
Command Descriptions, Continued sets up tracing on downstream port 2, for input data only. trace crosslink output sets up tracing of frames sent on the cross-link. The filter may also specify frames for a specific station by declaring an IP address. The station filter cannot be combined with the port specification in a single command. To collect data from or to a station the commands would look like: trace 9 trace 172.16.9.201 trace on The first command specifies the upstream port for trace data.
Command Descriptions, Continued “verbose” Command This command controls the event buffer display’s “verbose” mode. When verbose mode is on, the list command shows an expanded format for captured frames: Local> verbose on local>list MESSAGE NUMBER 502 IP DESTINATION 172.16.9.188 IP SOURCE 172.16.9.
