RS-485/422 Connection Guidelines
The RS-485/422 protocol provides a solution for wired communications that can tolerate high noise and push signals over long cable lengths. RS-485/422 signals can communicate as far as
4000 feet (1200 m). RS-232 signals are suitable for cable distances up to 100 feet (30.5 m).
RS-485 offers multi-drop capability in which up to 32 nodes can be connected. The RS-422 protocol is used for point-to-point communications.
Suggestions for integrating the XCite RF Modem with the RS-485/422 protocol:
1.
When using Ethernet twisted pair cabling: Select wires so that T+ and T- are connected to each wire in a twisted pair. Likewise, select wires so that R+ and R- are connected to a twisted pair. (For example, tie the green and white/green wires to T+ and T-.)
2.
For straight-through Ethernet cable (not cross-over cable) - The following wiring pattern works well: Pin3 to T+, Pin4 to R+, Pin5 to R-, Pin6 to T-
3.
Note that the connecting cable only requires 4 wires (even though there are 8 wires).
4.
When using phone cabling (RJ-11) - Pin2 in the cable maps to Pin3 on opposite end of cable and Pin1 maps to Pin4 respectively.

3. RF Modem Operation
3.1. Serial Communications
3.1.1. RS-232 and RS-485/422 Data Flow
The XCite RF Modem can enable a host device to communicate wirelessly. To transmit, the host device simply sends serial data to the XCite RF Modem pins. The RF modem then converts the data into FCC-approved RF data. Once transmitted, the RF data can be detected by receiving XCite RF
Modems, checked for integrity and then sent to a receiving device.
Figure 3‐01. Data Flow in RS‐232 and RS‐485/422 environments.
(Low‐asserted signals distinguished with a horizontal line over signal name.)
3.1.2. Serial Data
Data enters the MaxStream RF modem through the DI Pin as an asynchronous serial signal. The signal should idle high when no data is being transmitted.
The UART performs tasks (such as timing and parity checking) needed for communication. Serial communication consists of two UARTs which must be configured with compatible parameters
(Baud rate, parity, start bits, stop bits, data bits) to have successful communication. Each data packet consists of a start bit (low), 8 data bits (least significant bit first) and a stop bit (high). The following figure illustrates the serial bit pattern of data passing through the modem.
Figure 3‐02. Serial (UART) data packet 0x1F (decimal ʺ31ʺ) as transmitted through the XCite Module
Data Format is 8‐N‐1 (8 bits ‐ No Parity ‐ 1 Stop Bit)
In the example above, the MaxStream RF modem transfer 8 bits over-the-air [Selectable using BI
(Number of Bits) Parameter]. Start and stop bits of the UART signal are not transmitted over-theair, but are regenerated by the receiving modem

9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04]
3.2. Modes of Operation
XCite RF Modems operate in five modes.
Figure 3‐03. Modes of Operation
3.2.1. Idle Mode
When not receiving or transmitting data, the RF modem is in Idle Mode. The modem shifts into the other modes of operation under the following conditions:
• Transmit Mode (Serial data is received in the DI Buffer)
• Receive Mode (Valid RF data is received through the antenna)
• Sleep Mode (Sleep Mode condition is met)
• Command Mode (Command Mode Sequence is issued)
3.2.2. Transmit Mode
When the first byte of serial data comes through the DI Pin and arrives in the DI Buffer, the modem transitions into Transmit Mode. Once in Transmit Mode, the modem initializes a communications channel. During channel initialization, incoming serial data accumulates in the DI buffer.
After the channel is initialized, data in the DI buffer is grouped into packets (up to 64 bytes in each packet) and is transmitted. The modem continues to transmit data packets until the DI buffer is empty. Once transmission is finished, the modem returns to Idle Mode. This progression is shown below:
Figure 3‐04. Transmission of data
© 2007 MaxStream, Inc.
13
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04]
3.2.3. Receive Mode
If a modem detects RF transmitted data while operating in Idle Mode, it transitions into Receive
Mode to start receiving packets. Once a packet is received, it goes through the receiving-end of a
CRC (cyclic redundancy check) to ensure that the data was transmitted without error. If the CRC data bits on the incoming packet are invalid, the packet is discarded. If the CRC is valid, the packet is placed the DO Buffer. This process is shown in the figure below:
Figure 3‐05. Receive Mode Data Flow
The modem returns to Idle Mode after valid data is no longer detected or once an error is detected in the received data. If serial data-to-transmit is stored in the DI buffer while the modem is giving precedence to Receive Mode, the data will be transmitted after the modem finishes receiving data and returns to Idle Mode.

9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04]
3.2.4. Sleep Modes
Software Sleep
Sleep Modes enable the modem to enter states of low-power consumption when not in use. Three software Sleep Modes are supported:
• Pin Sleep (Host Controlled)
• Serial Port Sleep (Wake on Serial Port activity)
• Cyclic Sleep (Wake on RF activity)
In order to enter Sleep Mode, one of the following conditions must be met (in addition to the modem having a non-zero SM parameter value):
1.
The modem is idle (no data transmission or reception) for the amount of time defined by the ST (Time before Sleep) parameter.
2.
SLEEP pin is asserted.
Once in Sleep Mode, the radio modem does not transmit or receive data until it first returns to Idle
Mode. The return into Idle Mode is triggered by the de-assertion of the Sleep pin or the arrival of a serial byte through Data In pin.
The SM (Sleep Mode) command is central to setting all Sleep Mode configurations. By default,
Sleep Modes are disabled (SM = 0) and the modem remains in Idle/Receive Mode. When in this state, the modem remains constantly ready to respond to serial or RF activity.
Pin Sleep (SM = 1)
• Pin/Host-controlled
<Lowest Power Configuration> In order to achieve this low-power state, Pin 2 must be asserted
(high). The modem remains in Pin Sleep until the Sleep pin is de-asserted. The modem will complete a transmission or reception before activating Pin Sleep.
After enabling Pin Sleep (SM (Sleep Mode) Parameter = 1), Pin 2 controls whether the XCite Module is active or in Sleep Mode. When Pin 2 is asserted (high), the modem transitions to Sleep Mode and remains in its lowest power-consuming state until the Sleep pin is de-asserted. The XCite
Module requires 40ms to transition from Sleep Mode to Idle Mode. Pin 2 is only active if the modem is setup to operate in this mode; otherwise the pin is ignored. Once in Pin Sleep Mode,
CTS is de-asserted (high), indicating that data should not be sent to the modem. The PWR pin is also de-asserted (low) when the modem is in Pin Sleep Mode
Note: The modem will complete a transmission or reception before activating Pin Sleep.
Serial Port Sleep (SM = 2)
• Wake on serial port activity
Serial Port Sleep is a Sleep Mode setting in which the modem runs in a low power state until data is detected on the DI pin.
When Serial Port Sleep is enabled, the modem goes into Sleep Mode after a user-defined period of inactivity (no transmitting or receiving of data). This period of time is determined by ST (Time before Sleep) Command. The modem returns to Idle Mode once a character is received through the DI pin.
Cyclic Sleep (SM = 3-8)
Cyclic Sleep is the Sleep Mode setting in which the XCite Module enters into a low power state and awakens periodically to determine if any transmissions are being sent.
When Cyclic Sleep settings are enabled, the XCite Module goes into Sleep Mode after a userdefined period of inactivity (no transmission or reception on the RF channel). The user-defined period is determined by ST Parameter. [See ST (Time before Sleep) Parameter]
While the modem is in a low-power state, CTS de-asserted (high) to indicate that data should not be sent to the modem during this time. When the modem awakens to listen for data, CTS is asserted and any data received on the DI Pin is transmitted. The PWR pin is also de-asserted (low) when the modem is in Cyclic Sleep Mode. These pins are asserted each time the modem cycles
© 2007 MaxStream, Inc.
15
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] into Idle Mode to listen for valid data packets and de-asserts when the modem returns to Sleep
Mode.
The modem remains in Sleep Mode for a user-defined period of time ranging from 0.5 seconds to
16 seconds (SM Parameters 3 through 8). After this interval of time, the modem returns to Idle
Mode and listens for a valid data packet for 100 ms. If the modem does not detect valid data (on any frequency), the modem returns to Sleep Mode. If valid data is detected, the modem transitions into Receive Mode and receives the incoming packets. The modem then returns to Sleep
Mode after a Period of inactivity that is determined by ST "Time before Sleep" Parameter.
The modem can also be configured to Wake-up from cyclic sleep when the SLEEP pin is deasserted (low). To configure a modem to operate in this manner, PW (Pin Wake-up) Command must be issued. Once the Sleep pin is de-asserted, the modem is forced into Idle Mode and can begin transmitting or receiving data. It remains active until no data is detected for the period of time specified by the ST parameter, at which point it resumes its low-power cyclic state.
Note: The cyclic interval time defined by SM (Sleep Mode) Command must be shorter than the interval time defined by LH ("Wake-up Initializer Timer") Command. For example: If SM=4 (Cyclic 1.0 second sleep), the LH Parameter should equal 0xB ("1.1" seconds). With these parameters set, there is no risk of the receiving modem being asleep for the duration of the wake-up initializer transmission. The following section "Cyclic Scanning" explains in further detail the relationship between "Cyclic Sleep" and
"Wake-up Initializer Timer"
Cyclic Scanning. Each RF transmission consists of a wake-up initializer and payload data. The wake-up initializer contains initialization information and all receiving modems must Wake-up during the wake-up initializer portion of data transmission in order to synchronize with the transmitter and receive the data.
The cyclic interval time defined by the SM (Sleep Mode) command must be shorter than the interval time defined by LH (Wake-up Initializer Timer) command.
Figure 3‐06. Correct Configuration (LH > SM):
The length of the wake‐up initializer exceeds the time interval of Cyclic Sleep. The receiver is guaranteed to detect the wake‐up initializer and receive the accompanying payload data.

3.2.5. Command Mode
AT Command Mode provides access to AT-Settable parameters. These parameters extend flexibility in configuring modems to fit specific design criteria such as networking modems. Not all of the parameters in the XCite Module can be adjusted using AT Commands.
AT Command Mode
To Enter AT Command Mode:
1.
Send the 3-character command sequence "+++" and observe guard times before and after the command characters. [refer to ‘Default AT Command Mode Sequence’ below.] The ‘Terminal’ tab (or other serial communications software) of the X-CTU Software can be used to enter the sequence.
[OR]
2.
Assert (low) the CONFIG pin and turn the power going to the RF modem off and back on. To achieve this result, simultaneously press the Reset and Config switches [Figure 1-02]; release the Reset Switch; then after 1 second, release the Config Switch. The RF Modem then enters AT Command Mode at the modem's default baud rate
Default AT Command Mode Sequence (for transition to Command Mode):
• No characters sent for one second [refer to the BT (Guard Time Before) Command]
• Input three plus characters (“+++”) within one second
[refer to the CC (Command Sequence Character) Command.]
• No characters sent for one second [refer to the AT (Guard Time After) Command.]
All of the parameter values in the sequence can be modified to reflect user preferences.
To Send AT Commands:
Send AT commands and parameters using the syntax shown below.
Figure 3‐07. Syntax for sending AT Commands
To read a parameter value stored in the modem register, leave the parameter field blank.
The preceding example would change the modem’s Destination Address to "0x1F". To store the new value to non-volatile (long term) memory, the Write (ATWR) command must subsequently be sent before powering off the modem.
System Response. When a command is sent to the modem, the modem will parse and execute the command. Upon successful execution of a command, the modem returns an “OK” message. If execution of a command results in an error, the modem returns an “ERROR” message.
To Exit AT Command Mode:
1.
If no valid AT Commands are received within the time specified by CT (Command Mode
Timeout) Command, the modem automatically returns to Idle Mode.
[OR]
2.
Send ATCN (Exit Command Mode) Command.
For an example of programming the RF modem using AT Commands and descriptions of each configurable parameter, refer to the "RF Modem Configuration" chapter.

• 900 MHz, 9600 Baud (RF data rate), Hopping Channel Mode
• 900 MHz, 9600 Baud, Single Channel mode
• 900 MHz, 38400 Baud, Hopping Channel mode
• 900 MHz, 38400 Baud, Single Channel mode
XCite Modems can operate in both Single Channel and Hopping modes. Mode is selectable using the "Function Set" dropdown list of the "XCite Configuration" tab of the MaxStream-provided X-
CTU Software.
The XCite Module is shipped with a unique parameter set in its memory. Parameters within the set are organized under the following categories: AT Commands & Non-AT Settable Parameters.
4.1. Command and Parameter Types
4.1.1. AT Commands
AT Commands can be changed at any time by entering AT Command Mode and sending commands to the modem.
AT Commands can be modified using the any of the following means:
• X-CTU Software "Modem Configuration" tab
• X-CTU Software "Terminal" tab
• Terminal software program (such as "HyperTerminal")
• Microcontroller
4.1.2. Non-AT Settable Parameters (X-CTU Software configurable only)
Non-AT Settable Parameters can only be adjusted using the MaxStream-provided X-CTU Software.
To modify Non-AT Settable Parameter, connect the module to the serial com port of a PC (interface board is necessary for RS-232 connection) and modify parameter values through the X-CTU Software interface. These parameters enable features that need to be set before the module is used in the field.
Non-AT Settable Parameters can only be modified using the following means:
• X-CTU Software "Modem Configuration" tab

4.2. Configuration Software
X-CTU is a MaxStream-provided software program used to interface with and configure Max-
Stream RF Modems. The software application is organized into the following four tabs:
• PC Settings tab - Setup PC serial ports for interfacing with an RF modem
• Range Test tab - Test the RF modem's range and monitor packets sent and received
• Terminal tab - Set and read RF modem parameters using AT Commands
• Modem Configuration tab - Set and read RF modem parameters
Figure B‐1. X‐CTU User Interface (PC Settings, Range Test, Terminal and Modem Configuration tabs)
NOTE: PC Setting values are visible at the bottom of the Range Test, Terminal and Modem Configuration tabs. A shortcut for editing PC Setting values is available by clicking on any of the values.
Installation
Double-click the "setup_X-CTU.exe" file and follow prompts of the installation screens. This file is located in the 'software' folder of the MaxStream CD and also under the 'Downloads' section of the following web page: www.maxstream.net/support/downloads.php
Setup
To use the X-CTU software, a module assembly (An RF modem mounted to an interface Board) must be connected to a serial port of a PC.
NOTE: Failure to enter AT Command Mode is most commonly due to baud rate mismatch. The interface data rate and parity settings of the serial port ("PC Settings" tab) must match those of the module (BD (Baud Rate) and NB (Parity) parameters respectively).
Serial Communications Software
A terminal program is built into the X-CTU Software. Other terminal programs such as "HyperTerminal" can also be used to configure modems and monitor communications. When issuing AT
Commands through a terminal program interface, use the following syntax:
Figure B‐2. Syntax for sending AT Commands
NOTE: To read a parameter value stored in a register, leave the parameter field blank.
The example above issues the DT (Destination Address) command to change destination address of the modem to "0x1F". To save the new value to the modem’s non-volatile memory, issue WR
(Write) command after modifying parameters.

4.4. Automatic DIP Switch Configurations
Each time the RF Modem is powered-on, intelligence on the Max-
Stream Interface Board (located inside the RF Modem) sends AT
Commands that program the modem based on positions of the DIP
Switch. Automatic configurations that take place during the power-on sequence affect RF Modem parameter values as shown below.
To avoid overwriting previously stored custom configurations (due to the automatic configurations that take place each time the RF Modem is powered-on), it is necessary to disable a processor located on the XIB-R interface board. To disable the processor, populate J7 of the XIB-R Interface
Board. (By default, J7 jumper is not populated.)

DT (Destination Address) Command
<AT Command: Networking> DT Command is used to set the address of the XCite Radio Modem.
XCite Radio Modems use three network layers - the Vendor Identification Number (ATID), Channels (ATHP) and Destination Addresses (ATDT).
DT Command assigns an address to a radio modem that enables it to communicate only with radio modems that have matching addresses. This is similar to interconnecting several PCs under a common hub. All radio modems that share the same destination address can communicate freely with each other. Radio Modems in the same network with a different destination address (than that of the transmitter) will listen to all transmissions to stay synchronized, but will not send any of the data out their serial ports.

HP (Channel) Command
<AT Command: Networking> HP Command is used to set the radio modem channel number. A channel is one of three layers of addressing available to the XCite Radio Modem. In order for radio modems to communicate with each other, the modems must have the same channel number since each channel uses a different hopping sequence or single frequency. Different channels can be used to prevent modems in one network from listening to transmissions of another.
The XCite Radio Modem can operate both in Hopping and Single Frequency Channel Modes.
Switching between Single Channel and Hopping
Modes can only be done only using the "Function
Set" dropdown list on the "Modem Configuration" tab of the X-CTU Software
A "Hopping Channel" is a channel comprised of a group of frequencies. When in Hopping Channel
Mode, the radio modem hops between the frequencies them when transmitting data. This option utilizes FHSS (Frequency Hopping Spread
Spectrum) technology. This option helps bolster security in wireless data communications and also makes the system less prone to interference.
The 25 center frequencies available in Single Frequency Channel Mode are spaced 300 KHz apart.
Since each channel occupies a 500 KHz bandwidth, adjacent channels therefore overlap. If modems are used in the same vicinity but on different channels, the channels used should occupy every other channel at a minimum separation. If channels used on different radio modems can be separated more they should be. This will provide for more isolation and less interference.

HT (Time before Wake-up Initializer) Parameter
<Non-AT Settable Parameter: Sleep (Low Power)> If any modems within range are running in a
"Cyclic Sleep Setting", a wake-up initializer must be sent by the transmitter for the other radio modems to synchronize to the transmitter [see LH ("Wake-up Initializer Timer") Command]. When a receiving radio modem in Cyclic Sleep wakes, it must detect the wake-up initializer portion of the
RF packet in order to synchronize to the transmitter and receive data. HT Parameter sets time period of inactivity (no serial or RF data is sent or received) before a Wake-up Initializer is sent.
Base station tracks awake-status of remote radios. HT of base radio should be set shorter than ST
(Time before Sleep) of remote radios.
From the receiver perspective, after "HT" time elapses and the ST (Time before Sleep) Parameter is met, the receiver goes into cyclic sleep. Once in cyclic sleep, the radio modem must first detect the wake-up initializer and synchronize to the transmitter before it can receive data. Thus, when time "HT" time elapses, the transmitter then knows it needs to send a long wake-up initializer for all receivers to be able to synchronize to its next transmission. Matching "HT" to the "ST" time on the receiver(s) guarantees that all receivers will detect the next transmission.
Parameter Range: 0 - 0xFFFF [x 100 ms]
# of bytes returned: 2
Default Parameter Value: 0xFFFF (long wake-up initializer will not be sent)
Related Parameters: LH (Wake-up Initializer Timer), SM (Sleep Mode), ST (Time before Sleep)

ID (Modem VID) Parameter
<Non-AT Settable Parameter: Networking> ID Parameter reads and edits the modem's VID. VID is a MaxStream-specific acronym that stands for "Vendor Identification Number". RF modems can only communicate with other modems having the same VID.

LH (Wake-up Initializer Timer) Parameter
<Non-AT Settable Parameter: Sleep (Low Power)> LH Parameter adjusts the duration of time in which the wake-up initializer is sent. When receiving modems are put into the Cyclic Sleep Mode, they power-down after a period of inactivity (specified by ST (Time before Sleep) Parameter) and will periodically awaken and listen for transmitted data. In order for the receiving modems to initialize with the transmitter, they must detect ~35ms of the wake-up initializer. LH Parameter must be used whenever a receiver is operating in Cyclic Sleep Mode. This lengthens the wake-up initializer to a specific amount of time (in x 100 ms). The long wake-up initializer must be longer than the cyclic sleep time that is determined by SM (Sleep Mode) Command. If the wake-up initializer time were less than the Cyclic Sleep interval, the connection would be at risk of missing the wakeup initializer transmission. The following data and figures illustrate this behavior:
Parameter Range: 0 - 0xFF [x 100 ms]
# of bytes returned: 1
Default Parameter Value: 0x01 (0.1 second)
Related Parameters: HT (Time before Wake-up Initializer), SM (Sleep Mode), ST (Time before
Sleep)
Figure 4‐01. Correct Configuration (LH > SM)
The length of the wake-up initializer exceeds the time interval of Cyclic Sleep. The receiver is guaranteed to detect the wake-up initializer and receive the accompanying payload data.
Figure 4‐02. Incorrect Configuration (LH < SM)
The length of the wake-up initializer is shorter than the time interval of Cyclic Sleep. This configuration is vulnerable to the receiver waking and missing the wake-up initializer (and therefore also the accompanying payload data).

<AT Command: Networking> MK Command is used to set the radio modem address mask. All RF packets contain the Destination Address of the transmitting radio modem. When an RF packet is received, the transmitter's Destination Address is logically "ANDed" (bitwise) with the Address
Mask of the receiver. The resulting value must match the Destination Address or the Address Mask of the receiver for the packet to be received and sent out the receiving modem serial port. If the
"ANDed" value does not match either the Destination Address or the Address Mask of the receiver, the packet is discarded. (All "0" values are treated as "irrelevant" values and ignored.)
AT Command: MK
Parameter Range: 0 - 0xFFFF
# of bytes returned: 2
Default Parameter Value: 0xFFFF (When set to this value, the Destination Address of the transmitter must exactly match the Destination Address of the receiver.)
Related Commands: DT (Destination Address), HP (Channel)
NB (Parity) Parameter
<Non-AT Settable Parameter: Serial Interfacing>
NB Parameter allows parity for the modem to be changed. Parity is an error detection method in which a bit (0 or 1) is added to each group of bits so that it will have either an odd number of 1's or an even number of 1's. For example, if parity is odd, then any group of bits that arrives with an even number of 1's must contain an error.

Mode (if no data is ready to be transmitted). PW Command is only valid if Cyclic Sleep has been enabled using SM Command.
RE (Restore Defaults) Command
<AT Command: AT Command Options> RE Command restores all AT-settable parameters to factory default settings. However, RE Command will not write the default values to non-volatile memory. Unless the WR (Write) Command is issued after the RE Command, the default settings will not be saved in the event of radio modem reset or power-down.

5. Advanced Networking
5.1. Addressing
The XCite Radio Modems utilize three layers of addressing to communicate between radio modems. The network layers are depicted below. Only radio modems with the matching addresses are able to communicate. The main layers of XCite Networking and Addressing are:
• Vendor Identification Number (ATID)
• Channel (ATHP)
• Destination Address (ATDT)
Figure 5‐01. Addressing layers contained in the RF packet header
Each network layer provides a separate layer of filtration. The Vendor Identification Number (VID) provides the first layer of filtration through the ID (Modem ID) Parameter. If the incoming RF data carries a matching VID number, the data continues through to the subsequent Channel and Destination Address layers. The Destination Address is the last network layer and provides the most granular form of filtration. If at any point during the incoming RF data flow the numbers in question do not match, the data is discarded.
XCite Modules and RF Modems are built around a peer-to-peer protocol that inherently supports a multidrop type network (similar to RS-485). In their default state, any XCite radio modem will communicate with any other XCite radio modem in its default state.
5.1.1. Vendor Identification Number (ATID)
The bottom half of the ID (Vendor Identification Number) Parameter range is user-settable. The upper half of the range is factory-set and read-only. The value of the ID Command is called the
Vendor Identification Number (VID). A unique VID is available upon special request. The VID is programmed to the XCite Module at the factory and is stored in the modem's permanent memory.
Only modems with matching VIDs can communicate with each other.
VID addressing ensures that radio modems ignore transmissions and receptions of XCite Radio
Modems having a different VID in the same vicinity. To request a unique VID, contact MaxStream to obtain the VID Request Form.

9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04]
5.1.2. Channel (ATHP)
Channels provide a network layer from which channels can be used for isolation. HP (Channel)
Parameter is used to define channel values.
Hopping Channel Mode: HP Parameter value range is 0 through 6
Single Frequency Channel Mode: HP range is 0 through 0x18 (decimal range: 0 - 24)
In "Hopping Channel Mode", each channel utilizes a different pseudo-random hopping sequence to navigate through shared hopping channels. In the event that two modems from different networks collide on a channel, the two modems will jump to separate channels on the next hop. Multiple modem pairs can operate in the same vicinity with minimal interference from each other.
5.1.3. Destination Address (ATDT) and Address Mask (ATMK)
XCite Destination Addresses and Masks provide the means to set up global or local addresses for establishing modem groups, subnets, etc. The Destination Address network layer provides for more granular isolation of radio modems. The XCite Destination Addresses and Masks can be used to:
• Set up point-to-point and point-to-multipoint network configurations
• Provide greater flexibility in establishing modem groups, subnets, etc.
Each radio modem in a network can be configured with a 16-bit Destination Address to establish selective communications within a network. This address is set to one of 65535 values using DT
(Destination Address) Command. The default Destination Address is 0.
All radio modems with the same Destination Address can transmit and receive data among themselves. Radio modems having different Destination Addresses still detect and listen to the data (in order to maintain network synchronization); however, the data is discarded data rather than passing on through the DO pin.
Packet-based Radio Modems
XCite Radio Modems are packet based. This means all data shifted into one modem is packetized and sent out the antenna port. Because XCite modems use a peer-to-peer architecture, all modems on the same channel (ATHP) will receive the packet and decide whether to pass it to the host or to throw it away. Each transmitted packet contains information about the transmitting modem.
Any modem that receives a packet will check the address values and decide what to do with the packet. The options are as follows:
• Receive the packet as a global packet
• Receive the packet as a local packet
• Discard the packet
Address Mask
The mask parameter can be used to allow a base modem to receive data from a range of addresses. It may also be used to configure "subnets" of modems that communicate in a group together.
Refer to the “Bit-wise AND Truth” table for the Pseudo 'C' Code that qualifies the Destination
Addresses and address masks.
The Pseudo Code uses the bit-wise "AND" operation, "&". This operation is performed bit by bit on each of the 16 bits in the TXDT, RXDT and RXMK parameters.

The Address Mask can be used as an additional method of facilitating communications between modems. The Address Mask can be set to one of 65535 possible values using MK (Address Mask)
Command. The default value of the MK Parameter is 0xFFFF.
All transmitted data packets contain the Destination Address of the transmitting modem. When a transmitted packet is received by a modem, the Destination Address of the transmitter (contained in the packet) is logically "ANDed" (bitwise) with the Address Mask of the Receiver. If the resulting value matches the Destination Address of the Receiver, or if it matches the Receiver Address Mask, the packet is accepted. Otherwise, the packet is discarded.
Note:When performing this comparison, any "0" values in the Receiver Address Mask are treated as irrelevant and are ignored.
