1.0 Overview
A BRIDGE separates two network segments within the same logical network (subnet).
A ROUTER forwards data across internetworks (different subnets).
A SERIAL GATEWAY allows asynchronous serial data to enter (as through a gate) the realm of IP communications.
The serial data is encapsulated within UDP or TCP packets.
IP9xx Series
The IP Series is a high-performance wireless ethernet bridge and serial gateway. Alternately, a Master IP Series unit may be config­ured to operate as a wireless ethernet router (and serial gateway).
When properly configured and installed, long range communications at very high speeds can be achieved.
The IP Series operates within the 902-928MHz ISM frequency band, employing frequency hopping spread spectrum (FHSS) and also, for
1.1Mbps operation, digital transmission service (DTS) technology.
They provide reliable wireless ethernet bridge functionality as well gateway service for asynchronous data transfer between most equip­ment types which employ an RS232, RS422, or RS485 interface.
The small size and superior performance of the IP Series makes it

2.0 Quick Start
To connect an IP Series to a PC, an ethernet CROSSOVER (not a straight-through) cable must be used.
IP9xx Series
The ethernet connections are dependent upon what is available to work with for the test configuration. For the purposes of this QUICK START, the assumption is that a LAN connection is available (with Internet connectivity) and that the PC is connected to this LAN.
Disconnect the PC‘s LAN connection from its NIC card
and insert the now ‗loose end‘ of the ethernet patchcable
into the rear ETHERNET RJ45 connector at the rear of the MASTER IP Series.
Using a CROSSOVER cable, connect the PC‘s NIC card
RJ45 jack to the ETHERNET RJ45 connector on the RE­MOTE IP Series.
At this point there is a wireless connection between the PC and the LAN, and you should be able to go about your typical networking ac­tivities, including accessing the Internet (via the LAN).
Also, by opening a web browser and entering the IP address of either
IP Series, you will be taken to the respective unit‘s Web User Inter-
face LOGIN window.
If communications not available as outlined above:
Verify the RSSI LEDs on the front of each IP Series are
illuminated.
Verify TX (red) LED activity on the front of each IP Se-
ries.
Observe the rear of each IP Series, specifically the
ETHERNET connection: the green LINK LED should be illuminated (indicating proper cabling) and the amber (ACTIVITY LED) should also be flickeringindicating DATA traffic at the ETHERNET connector.
If using Windows XP, the firewall function could inhibit
desired data traffic. Anti-virus software may also have a negative impact.

When initially cabling between devices, pay close attention to the Activity LED to confirm that proper patchcable types are being used.
Receive Signal Strength Indicator (RSSI) (3x Green) LEDs
As the received signal strength increases, so does the number of illuminated RSSI LEDs, starting with the furthest left. RSSI is calculated based on the last four valid recieved packets. For robust wireless communications performance, strive for a minimum of 2 RSSI LEDs being lit.
Initially, a remote unit‘s RSSI LED‘s will ‗scan‘ (cycle from right to
left, each LED being on for 300ms in turn). Once the unit acquires
synchronization with the network, a ‗steady‘ RSSI reading will be
displayed. A Master updates its RSSI indication upon receiving valid packets
from remote units. It takes into consideration packets received from both Repeaters and Remotes.
A Repeater will base its RSSI reading on valid packets received from Slaves; if the Slaves are silent for 2 seconds, the Repeater will display an RSSI value based on valid packets received from the Master.
Signal strength is calculated based on the last four valid received packets with correct CRC.
3.2.2 Rear Indicators
Collision LED (Amber)
Located at top/left of the ETHERNET connector, illuminates when there is a collision on the ethernet interface.

4.0 Operating Modes
Throughout this manual, Remote‘ refers to a Remote as defined in Section 4.4; the
general term ‗remote‘ applies
to an IP Series Repeater and/ or Remote - i.e. non-Master
IP9xx Series
An IP Series may be configured for any operating mode: this is very convenient for purposes of sparing and becoming familiar with their configuration menus.
4.1 Master
One per network, the source of synchronization for the system. The Master controls the flow of data through the system.
4.2 Repeater
Required only if necessary to establish a radio path between a Mas­ter and Remote(s); stores and forwards the data sent to it. Synchro-
nizes to Master and provides synchronization to ‗downstream‘ units.
If a local device is attached to a Repeater‘s serial data port, the Re-
peater will also behave as a Remote (aka Repeater/Remote).
As they are added to a radio network it is good practice to use the values 2-17, sequentially, for Repeater Unit Addresses.
Adding one or more Repeaters within a network will HALVE the throughput; the throughput is halved only once, i.e. it does not de­crease with the addition of more Repeaters.
If there is a ‗radio (signal) path‘ requirement to provide Repeater
functionality, but throughput is critical, the repeating function may be
accomplished by placing two IP Series at the Repeater site in a ‗back
-to-back‘ configuration. One IP Series would be configured as a Re-
mote in the ‗upstream‘ network; the other a Master in the ‗downstream‘ network. Local connection between the modems
would be accomplished with a crossover cable (for the ethernet con­nection). Each modem would require its own antenna; careful con­sideration should be given with respect to antenna placement and IP Series configuration.
4.3 Remote
Endpoint/node within a network to which a local device is attached. Communicates with Master either directly or through one or more Repeaters. See Sections 5.3 and 5.4 for information regarding ‗Slave-to-Slave‘ communications.
© Microhard Systems Inc. CONFIDENTIAL 29
Page 30
5.0 Network Topologies
The RADIO network topology determines the paths available for the movement of data.
Take this important fact into consideration when selecting a network topology.
IP9xx Series
The IP Series may be configured to operate in a number of different operating modes and participate in various network topologies.
Note: This section describes radio network topologies in general and includes examples of corresponding Radio Configuration set­tings. Refer to section 6 for further detailed information regarding configuration options.
5.1 Point-to-Point (PTP)
In a Point-to-Point network, a path is created to transfer data be­tween Point A and Point B, where Point A may be considered the Master modem and Point B a Remote. Such a PTP network may also involve one or more Repeaters (in a store-and-forward capac­ity) should the radio signal path dictate such a requirement. (Note that a Repeater may also concurrently function as a Remote, i.e. it may pass data to and from an attached device(s).)
A PTP configuration may also be used in a more dynamic sense: there may be many Remotes (and Repeaters) within such a net-
work, however the Master may have its ‗Destination Address‘
changed as and when required to communicate with a specific re­mote unit.
An example of a basic PTP network consisting of two IP Series is on the next page.
Notes re Example 5.1.1:
Configuration options are based upon the chosen Op-

erating Mode of the unit: select the Operating Mode first.
ADDRESS of the REMOTE, and vice versa (noting that
the MASTER‘s Unit Address (not visible) is preset, and
must remain as, ‗1‘).
TER is not as critical a setting as it is in a Point-to­Multipoint (PMP) system.

IP9xx Series
5.2 Point-to-Multipoint (PMP)
In a Point-to-Multipoint network, a path is created to transfer data between the Master modem and numerous remote modems. The remote modems may simply be Remotes with which the Master communicates directly, and/or Remotes which communicate via Repeaters. Some or all of the Repeaters may also act as Remotes in this type of Network, i.e. the Repeaters are not only storing and forwarding data, but are also acting as Remotes. Such Repeaters may be referred to as ‗Repeater/Remotes‘.
Example 5.2.1
A 4-node network consisting of a Master, 1 Repeater, and 2 Re­motes. 1 Remote is to communicate with the Master through a Re­peater; the other is to communicate directly with the Master.

the DESTINATION is preset to 65535: the BROAD­CAST address (‗multipoint‘).
RETRANSMISSIONS are set to 0. Refer to Section
6.1.4 for more information.
There is a REPEATER in this example network, there-
fore the MASTER‘s ‗Repeater‘ configuration option is
set to Yes.

When bench testing PMP with a REPEATER in the network, configure the REMOTE to sync h r o n i z e to t h e REPEATER via t he

ADDRESS field. If this is not done, with the REMOTE in close proximity to the MASTER and its ROAMING set as 1 (default), the REMOT E will simply synchronize with (and pass data directly to) the MASTER, bypassing the REPEATER altogether.
Image 5D: PMP Example 5.2.1: Repeater
The ROAMING address for the REPEATER is set to 1:
the UNIT ADDRESS of the MASTER. This means that this REPEATER will synchronize to, and communicate directly with, the MASTER.
There is no DESTINATION UNIT field for remote units
in a PMP network: the destination is predefined as ‗1‘ (the MASTER ‗point‘).
On the following page are the configurations for the REMOTES.
Remote 20‘s ROAMING ADDRESS is set to 2, the
UNIT ADDRESS of the REPEATER. This Remote will synchronize to the Repeater and communicate via the Repeater to the Master.
Remote 30‘s ROAMING ADDRESS is set to 1 (the
UNIT ADDRESS of the MASTER): it will synchronize to, and communicate directly with, the MASTER.

A P2P network requires a Master modem.
The data being transmitted from one Remote to another in P2P mode is transferred via the Master.
IP9xx Series
5.3 Peer-to-Peer (P2P)
P2P mode is used for communications between pairings of remote modems,
e.g. Remote 20 can exchange data with (only) Remote 30, Remote 21 can exchange data with (only) Remote 35, etc.
The Master will resend the data incoming to it from both Remotes to
both/all Remotes; one Remote‘s data has a Destination Unit being
the other Remote and vice versa.
Example 5.3.1
A device located at a pump station must communicate bi­directionally with another device at a water tank. The MASTER IP Series must reside in an office at a separate location.

An E2E network requires a Master modem.
The data being transmitted from remote units in an E2E network travels to the Master and is then re-broadcast to all other remotes.
IP9xx Series
5.4 Everyone-to-Everyone (E2E)
E2E mode is used for communications between all remote mo­dems,
i.e. data from every modem is broadcast to every other modem in the network.
Considering the amount of data re-broadcasting (via the Master), it is a very bandwidth-intensive network topology.
Example 5.4.1
1 Master and 3 remote units must all communicate with each other.

The following factors must be considered when preparing to config­ure the modems:
the application network topology physical distribution of the network data interface requirements
Components involved in the configuration process of the IP Series:
interfacing with the modem, and selecting and inputting the desired operational parame-
ters
Interfacing to the IP Series for the purpose of initially configuring it may be accomplished in one of two ways:
front COM2 connector, Microhard Systems Inc. DE9-
RJ45 Diagnostics Cable (P/N MHS044000, black), and a PC running terminal communications program (e.g. HyperTerminal), or
rear ETHERNET (RJ45) port, ethernet crossover cable,
and PC running Microhard Systems Inc. DiscoverIP util­ity and Web Browser application.
All configuration of the IP Series is accomplished with a PC. There are no DIP switches to set; switches which may subsequently be­come inadvertently misadjusted or intermittent.

gateway‘s IP address will be entered into this field. If there is a
DHCP server on the network, and the IP Address Mode (see previous page) is selected to be DHCP, the DHCP server will populate this field with the appropriate gateway address.
In a very small network (e.g. point-to-point, and STATIC IP Address Mode), the gateway value is not critical. The IP address of the most significant device on the overall network may be entered, or, if
only two IP Series‘s are being used, make the gateway of IP Series
No. 1 = IP address of IP Series No. 2; gateway of IP Series No. 2 = IP address of IP Series No. 1. The idea behind this approach is: If
an IP Series at ‗one end‘ of a wireless link receives a packet it is
unsure where to send, send it to the other end of the wireless link (i.e. the other IP Series) where it was quite likely destined.
A simple way of looking at what the gateway value should be is: If a device has a packet of data is does not know where to send, send it to the gateway. If necessary - and applicable - the gateway can forward the packet onwards to another network.

6.1.4.3 DHCP Server Configuration
There is a difference in how the DHCP Server operates based on whether the IP Series unit (Master) is configured to function as a bridge or a router.
6.1.4.3.1 Bridge
The IP Series Master may be configured to provide dynamic host control protocol (DHCP) service to all attached (either wired or wire­less-connected) devices.
Configuration field descriptions are discussed in the following sec­tion.
6.1.4.3.2 Router
An IP Series Master may be configured to provide dynamic host con­trol protocol (DHCP) service for an entire LAN (or section thereof). Recall that the LAN consists of wirelessly connected IP Series units and those IP addressable devices which are connected to them. If this feature is to be utilized, it would be enabled on the Master IP Series unit, noting that such a DHCP Server service must not be en­abled on any other IP Series units or devices which reside on the same network segment.
With this service enabled on the Master, it can assign IP addresses (as well as subnet mask and gateway) to the LAN radios and IP de­vices attached to them provided they are set for DHCP as opposed to static.
The DHCP Server may also be used to manage up to five MAC ad­dress bindings. MAC address binding is employed when certain de­vices are to be assigned specific IP addresses (effectively issuing
them a ‗static‘ IP address). Such devices are identified by their
unique MAC address: the DHCP Server ensures that a specified IP address is assigned to a specific MAC address (hence, device - ei­ther an IP Series or other IP-based device attached to the LAN).

SNMP: Simple Network Management Protoc ol provides a method of managing network devices from a single PC running network manag ement software.
Managed networked devices are referred to as SNMP agents.
IP9xx Series
6.1.4.4 SNMP Agent Configuration
The IP Series may be configured to operate as a Simple Network Management Protocol (SNMP) agent.
Network management is most important in larger networks, so as to be able to manage resources and measure performance.
SNMP may be used in several ways:
configure remote devices monitor network performance detect faults audit network usage detect authentication failures
A SNMP management system (a PC running SNMP management software) is required for this service to operate. This system must have full access to the IP Series network. Communications is in the form of queries (information requested by the management system) or traps (information initiated at, and provided by, the SNMP agent in response to predefined events).
Objects specific to the IP Series are hosted under private enterprise number 21703.
An object is a variable in the device and is defined by a Management Information Database (MIB). Both the management system and the device have a copy of the MIB. The MIB in the management system provides for identification and processing of the information sent by a device (either responses to queries or device-sourced traps). The MIB in the device relates subroutine addresses to objects in order to read data from, or write data to, variables in the device.
An SNMPv1 agent accepts commands to retrieve an object, retrieve the next object, set and object to a specified value, send a value in response to a received command, and send a value in response to an event (trap).
SNMPv2c adds to the above the ability to retrieve a large number of objects in response to a single request.
SNMPv3 adds strong security features including encryption; a shared password key is utilized. Secure device monitoring over the Internet is possible. In addition to the commands noted as supported above, there is a command to synchronize with a remote management sta­tion.

6.1.4.7 VLAN
The IP Series implementation of VLAN (Virtual LAN) is currently only supported when the unit is configured in Bridge Mode. Once configured VLAN functionality can be provided as a VLAN filter, a VLAN tagger or a VLAN blocker. VLAN compatible devices can be config­ured to provide a VLAN TAG in the ethernet frame. Using this tag, data can be virtually filtered or blocked, and data from unsupported devices (serial data, etc) can be tagged, then filtered or blocked as required. This can be done at the wired and/or wireless ports
VLAN: A virtual LAN is a group of hosts that communicate as if they were attached to the same broadcast domain, not dependant upon their actual physical location.
eliminating unwanted or unneeded data, providing additional security and conserving valu­able bandwidth.
IP9xx Series
Management VLAN is used for purposes such as telnet, SNMP, and syslog. By default, VLAN 1 is the management VLAN.
Primary VLAN (VLAN 1) is a logic VLAN tag which can not be created or altered by the users. All Ethernet frames without a VLAN tag ( i.e. Untagged frames) will be treated in this logic VLAN.
User VLANs (VLAN 2 4094) are actual VLANs which can be created or deleted by the users. All Ethernet frames in this VLAN will contain the specified VLAN tag.
Once VLAN is enabled, but before any VLANs are created other than the primary VLAN (VLAN1), the unit will actually pass any untagged frames and drop any VLAN tagged
frames. VLAN ID‘s can then be created, lets say 2, 3. Once VLAN 2 and 3 are created a
user can define on the Wired Port and Wireless port what happens to the data. There are
3 options in the list: filter, tag and exclude. When you specify ―Filter‖ option on both ports
(by default), the unit will then pass all untagged frames as well as frames tagged with VLAN ID 2 and 3. By this mean we can eliminate unwanted wireless traffic and save our
valuable bandwidth. When you specify ―Tag‖ option on the Wired Port and ―Filter‖ option on the Wireless port, the unit will then ―tag‖ those untagged frames entering wired port with VLAN id 2 (or 3) and pass them on the wireless port. You may also specify ―Exclude‖ op-
tion on either Wired port or Wireless port, which means frames with VLAN id 2 ( or 3) will be blocked at the Wired or Wireless port specifically.
By default the management VLAN is set to Primary VLAN (VLAN 1). You may change it to any user VLAN, let's say VLAN 3, all frames generated from this unit, for example the serial data, will be tagged as VLAN ID 3. It can be passed or dropped by itself, depending on the VLAN setting on the bridge. You can only telnet or web access the unit by VLAN 3 in this case.

In a PMP system, set Retransmissions to the minimum value required as, effec tivel y, the data throughput from Master to Remotes is divided by 1 plus the Retransmissions value.
IP9xx Series
Retransmissions
This register determines the maximum amount of times that a packet will be retransmitted (in addition to the initial transmission), noting the following specific behaviours in various network topologies:
PMP: Master will retransmit each data packet the exact number of times specified in the Retransmissions field; Remote will retransmit only if necessary, and then only until a given packet is
acknowledged or the value of the Remote‘s Retransmissions field is
reached (after which it will discard the packet if retransmission not
successful). *See also ‗PMP with ACK‖ described in the Network
Type (below). PTP: IP Series will retransmit to its counterpart only if necessary,
and to a maximum number of the value specified in its Retransmissions field. Packet is discarded if retransmissions are not successful.
ALL modems in a network must have the SAME value for Network Type.
Values
0-255

Network Type
Defines the type of RADIO network (see Section 5.0 for a detailed description of network topologies).
In a point-to-multipoint (PMP) network, the Master broadcasts data to all units, and all remote units send their data (ultimately) to the Master.
A point-to-point (PTP) network involves a Master and a Slave (with 0 or more Repeaters between them).
Peer-to-Peer (P2P) supports communication (through the Master) between 2 (typically remote) units.
In an Everyone-to-Everyone (E2E) network, all units communicate with all other units, through the Master. Note that this mode is very bandwidth-intensive. continued...

6.0 Configuration
Keep in mind that the Network Type determines the path that data will take.
i.e. In a PMP system, the data flows from the Master to Remotes, and from Remotes to the Master. If a ping to Remote B was sent to Remote A, it will not arrive as the data cannot travel from Remote to Remote. Similarly, a ping to a Repeater from a Remote will not arrive either: the destination for a Remote in a PMP system is the Master - not a Repeater, even though it appears in the data ‗path‘ to the Master.
IP9xx Series
Network Type (continued)
Point-to-Multipoint with ACK is a configuration whereby the Network functions as a Point-to-Multipoint, but the Retransmissions behave as a combination of PTP and PMP in that: If retransmissions are set to 5 (for example) on the Master, and the packets it sends to the Remotes result in an ACK being received by each of the Remotes in the network, the Master will not send the data again (refer to the PMP behavior described in the preceding Retransmissions section). If, however, the Master does NOT receive an ACK from all Remotes in the network, it will then revert to sending the data again, to the maximum number of Retransmissions specified, for a period of one minute, after which time it will revert to behaving as it did originally.
This mode of operation is particularly well-suited to fixed PMP networks when multipoint operation is required as is maximum throughput.
The selected Network Type will effect the Radio Configuration menu somewhat, i.e. If Point-to-Multipoint is selected for a Remote, there is no menu item for a Destination Address as the destination is - must be - the Master (Unit Address 1).

Destination Unit
As the name implies, this register specifies the ultimate destination
for an IP Series‘s data. Different network topologies dictate the
configuration of the Destination Unit (address): For a Remote in a Point-to-Multipoint network, this menu option will
not appear: by definition, the destination is the Master (UA = 1). For the Master in PMP, its Destination Unit (Address) is 65535the broadcast address as it sends its data to all points.
In a Point-to-Point configuration, the destination is to be specified
(for a Remote: the Master); in the Master‘s Radio Configuration,
specify the Unit Address of the Remote Unit to which it is to send its data.
In Peer-to-Peer, the Remotes are configured with the target peer‘s UA as the Destination Address, the Master with 65535; in Everyone
-to-Everyone, the Destination Address for ALL units is 65535 - the broadcast address - as every unit sends its data to every other unit (through the Master). E2E is a very bandwidth intensive network topology.
Values

Tx Control
This configuration option does not apply to a Master IP Series. On (the default) permits the IP Series to transmit, i.e. RF emissions

Off configures the IP Series for RECEIVE ONLY. If ‗Off‘ is selected, ‗On‘ may only be selected LOCALLY or via a special UDP
packet sent from the DiscoverIP Utility.

When bench testing 3 IP Series for a Master-Repeater­Remote link, be sure to set
the Re m ote‘s Roaming
Address to the Unit Address (UA) of the Repeater, and the
Repeater‘s Roaming Address
to the UA (1) of the Master. This will ensure that data is
routed from the Remote through the Repeater to the Master; otherwise, if the
Remote‘s Roaming Address
is left at the default value of 1, the Remote will communicate directly with the Master, bypassing the Repeater altogether.
IP9xx Series
Roaming Address
This feature allows a Remote unit to synchronize with a specified
‗upstream‘ unit (either Master or Repeater). The options are as
follows: 65535: With this value as its Roaming Address, a Remote will
synchronize with an upstream unit which has the same Network Name as the Remote. Should that upstream unit fail, this Remote
will attempt to synchronize with another ‘upstream‘ unit within the
same network (i.e. same Network Name). This ability is particularly well-suited to mobile applications.
1-254: In most static (fixed) networks, where there are no Repeaters, the default value of 1 is maintained: All Slaves synchronize to the Master (whose unit address is 1).
In networks where Repeaters are present, the value of a Remote‘s Roaming Address typically corresponds to the particular upstream modem with which a particular Remote is intended to communicate, e.g. Slave with Unit Address 3 may have a Roaming Address of 2, where the modem with Unit Address 2 is a Repeater between the Slave and the Master; the Repeater will have a Roaming Address of 1 as it is to synchronize to the Master.
The Roaming Address dictates to which IP Series (by Unit Address
(UA)) a Remote (or Repeater) will ‘look‘ or ‘attach to‘ for its
upstream signal path. See the description of Network Profile earlier in this section for
more information about roaming-type options. The Network Profile allows for roaming between networks whereas the Roaming Address provides for roaming within a network.

With one or more Repeaters
in the system, a network‘s
throughput is divided in half. Exercising the option of back­to-back ‗Repeaters‘ - which requires 2 IP Series at a ‗Repeater‘ site - eliminates the division of bandwidth.
If there is more than one Repeater in a network, the Repeaters should be
‗registered‘. See ‗Repeater Registration‘ further along in
this section re how to accomplish this.

Zone Restriction
Zone restriction dictates within which band (zone) of frequencies that a particular unit will operate.
Using zones simplifies network deployment by providing a convenient reference (e.g. Zone 1) within which a given network can operate, thereby minimizing the potential for internetwork interference. This is particularly useful when used in conjunction with Network Search Mode to facilitate minimal interference among adjacently deployed networks.
The tables on the following page illustrate the various zones and their associated frequency restrictions. Note that there is a
difference between zone ‗values‘ depending on the Wireless Link
Rate selected.

Frequency Restriction
By default, the IP Series will hop on frequencies across the entire 902-928MHz ISM band. For some applications or within certain operating environments it may be desired to prohibit the modem from operating on specific frequencies or range(s) of frequencies.
(See Section 6.1.8.4 for a description of the Radio Channel Noise Levels tool.)
The modem will not allow ‗too many‘ frequencies to be restricted; it
requires a certain amount of bandwidth within which to operate to comply with regulations.

Use the Radio Channels Noise Level tool (see Section 6.1.8.4) to help identify the frequency/ range of possible interfering signals within the 902-928MHz ISM band, and then use the Frequency Restriction feature to configure the IP Series to avoid them.

The input format is: UA: channel number, or
UA: channel number-channel number z, or UA: channel number,<no space>chnl number-chnl number
where UA is the Unit Address, and channel number is the channel number (not frequency) of the channel to be restricted.
The input formats above describe single channel, range of channels, or a combination thereof. A number of input fields may be used, or a combination of restrictions input in one field.

The Frequency Restriction ‗value‘ must be input into EVERY
MODEM in a network. Oftentimes the applicable Unit Address (as input in the format detailed previously) will be ‗1‘ - indicating that that the Master modem - to which other units synchronize - will not be transmitting on the specified channel(s). All units in the system will use this information - as input into each one of them - to generate the appropriate hopping pattern for the network.

The menus ‘COM1 Configuration‘ and ‘COM2 Configuration‘ are
used to configure the serial device server for the serial communications ports:
COM1, the rear DE9 connector on the IP Series, and COM2, the front RJ45 connector, respectively.
Serial device data may be brought into a LAN network through TCP, UDP, or multicast; it may also exit the IP Series network on another IP Series‘s serial port.
COM1 is a full-featured RS232 interface dedicated to serial data traffic. It supports hardware handshaking. By default, this port is enabled.
COM2 is, by default, disabled. In this state, it may be used as the console port for the text user interface. Enabled, it becomes another serial port for data traffic. It is a 3-wire (TxD, RxD, and SG) interface and does not support hardware handshaking.
For brevity, only COM1 is fully detailed in this section; the relative limitations of COM2 are noted where applicable.
