Connections and Components Gateway-In-A-Stick Connections The Gateway-In-A-Stick is supplied with a 6’ conductor cable. The connections are as follows: Wire Color Connection Positive Power (6 to 36 VDC) BLACK Ground GREEN RS-485 “A”, 9600 Baud BROWN RS-485 “B”, 9600 Baud ORANGE RS-232 Debug/Programming TX, 9600 Baud YELLOW... -
Page 6: Operation
Operation The Gateway-In-A-Stick supports all remote SignalFire nodes making all remote sensor data available in Modbus format. The register data from remote sensor nodes is available by requesting the remote node’s Modbus ID and register address from that node’s register map. The gateway will respond with the most recent copy of the data from the remote node. -
Page 7: Setup
Setup The Gateway-in-a-Stick requires an initial configuration over RS-232 using the SignalFire Toolkit. Connect a USB-Serial cable (can be purchased from SignalFire) between a computer and the Gateway’s DB9 port. The following items must be configured to set up a SignalFire network: Radio Network Radio Network Group Corporate ID/Encryption Key... - Page 8 Using the SignalFire Toolkit The SignalFire Toolkit application can be downloaded at www.signal-fire.com/customer. After installation, launch the software and the main toolkit window will open: Select the COM port associated with the Gateway Stick and click “Auto-Detect Device on COM Port.” This will open the device configuration window, where all device settings can be configured.
-
Page 9: Encryption
Network Setting The network is set using the SignalFire Toolkit. There can only be one Gateway per network/group/encryption combination, otherwise they will conflict. In a system with multiple Gateways, each Gateway must be on a separate network/group/encryption combination. The network, network group, and corporate ID/encryption key settings must match those of its nodes for them to communicate. -
Page 10: Checking Remote Nodes
Checking Remote Nodes If one or more remote nodes are configured with the correct network settings, they will send their data to the gateway. Clicking Refresh List will populate the list with all connected remote nodes. The gateway displays the node type, node name (if it has been set), RSSI signal strength, check-in interval, the Time-To-Live (TTL), and the node’s radio and main firmware versions. -
Page 11: Remote Node Configuration
Remote Node Configuration The SignalFire Gateway allows configuration changes to be made to any of the connected SignalFire remote nodes wirelessly. To use this feature, access to the Gateway debug port is required. This may be accessed over a TCP/IP network using a SignalFire Ethernet Gateway module, or by a direct connection to the Gateway RS232 port. - Page 12 Settings Make any necessary changes and click the Apply All button to save the changes. When finished with the configuration, close the configuration window and then click the button in the Gateway window to end the session. The session will also automatically time-out after 15 minutes of inactivity and the Node will resume normal operation.

Page 13: Firmware Upgrades
Firmware Upgrades Firmware updates for both the gateway (ARM) and the built-in radio are possible over the RS-232 debug interface using the SignalFire Toolkit, or over a remote TCP connection if an Ethernet Gateway module is used. Gateway (ARM) Firmware update steps Open the SignalFire Toolkit application. -
Page 14: Remote Shutdown (Rsd) Control
Remote Shutdown (RSD) Control Internal Logic Control The SignalFire Gateway supports capability which enables the Gate- way to control output relays on SignalFire RSD sticks. The SignalFire Gateway Stick receives data from multiple remote nodes. It can use the data from those remote nodes to set the relay output on one or more remote RSD sticks. -
Page 15: Rsd Configuration
RSD Configuration Settings From the Gateway configuration window within the SignalFire Toolkit, go to the Remote Shutdown Settings menu and select . This will open the RSD configuration window. Source Value Section The ‘Source Value’ section is used to select the source register for the logic rule. Modbus ID –... -
Page 16: Relay Control Logic Section
Relay Control Logic Section The ‘Relay Control Logic’ section is used to set the trigger thresholds for the selected source data register. Run System (Energize Relay) – Select the logic operand to use for the “energize” logic evaluation. Value – The value that the relay will be energized. Note that the energized state is the normal “operating” state of the relay. -
Page 17: Destination Rsd Stick Section
Destination RSD Stick Section Modbus ID – The Modbus ID of the destination Counter Stick. Relay Channel – Select the relay channel to switch Current Relay State – Shows the last value of the relay as reported to the gateway (except for IO1 module). Clicking the Update button will refresh this value. -
Page 18: Example
Example Line 1 has been configured with a source data node as a Sentinel-Analog with the loop current (in μA) as the selected register. The relay will energize when the loop current is above 1400μA (14mA) and de-energize when the loop current is below 1300μA (13mA). Note that this configuration has a 1000μA (1mA) hysteresis factor. -
Page 19: Additional Options
Additional Options There are two check boxes for additional logic options. Failsafe Enabled – If this option is selected rules must have valid data for the relay to be energized. If one or more of the nodes times-out or does not exist the relay will be de-energized. If this option is not selected, then a node that is not installed or fails to check in will be ignored and the relay will be energized using logic only from the units that are active. -
Page 20: Modbus Register Remapping
Modbus Register Remapping The gateway allows any of the remote register data to be remapped to a single block of registers available at the Gateway’s Modbus ID (default is 247). This is useful for collecting a subset of register data from multiple nodes and making it readable in a single block of registers. Up to 1500 registers can be remapped to the gateway’s Modbus ID starting at register 5000. -
Page 21: Use Data Type Floats
Use Data Type Floats The Gateway s Modbus Register Remapping provides an option to remap all registers to 32-bit floats. This allows the user to enter a register and its data type knowing that it will be read from the gateway via Modbus as two 16-bit registers. To use the floating-point remapping, select the ‘Use Data Type Float’... -
Page 22: Fail Mode
Fail Mode If the gateway does not have data for a remapped value it will respond with 0xFFFF, or 0x0000 for the register request, configurable globally with the Fail Mode settings. Modbus ID 21 isn't reporting in, fail mode set to "high" Load/Save Files The displayed remap information can be saved to a proprietary file by clicking the ‘Save to File’... -
Page 23: Rs485 Details
RS485 Details The Gateway keeps a log of any Modbus requests made to either itself or any Modbus nodes connected to it. The Modbus Transmission Log can be viewed under the Tools menu by selecting “RS485 Details”. When the Gateway is open in the ToolKit, this log will be automatically written to the Log folder. The RS485 Modbus Details window also has a ‘Send Log to Tech Support’... -
Page 24: Gateway Event Log
Gateway Event Log Starting with Gateway Firmware version 7.81 the Gateway keeps an internal log of events. The event log can be viewed from the gateway window of the ToolKit by clicking ‘View Gateway Log’ at the bottom of the window. The gateway log events such as reboots, remote nodes joining/timing out, local RSD control events, remote configuration sessions, firmware updates, and more. -
Page 25: Modbus Gateway Register Map
Modbus Gateway Register Map Only the The SignalFire Modbus Gateway by default is assigned Modbus ID number 247. Gateway status/configuration and remapped registers are read at this address. remote node registers are read from the Modbus ID and register address of the remote node unless Modbus register remapping is used. -
