SIG-0 Mini-Gateway
Communication Bridge / Network Adapter

1
Introduction
The SIG-0 Mini-Gateway is a communication bridge that connects a powered RS-232 hub and a TCP
socket to facilitate communication between the RS-232 and network devices. The SIG-0 must receive power
through the RJ45 serial connection cable from a compatible device such as Model 1798. Congure and store
data directly on the device via the integrated microSD port or serial commands. The device can be mounted
directly to a at surface using the mounted anges.
Features
• Serves as a communication bridge between an RS-232 device and a network device.
• Powered via RS-232 connection (requires compatible power injector such as 1798).
• Able to load, congure, and store information via serial commands or a conguration le on a microSD card.
• Packages incoming RS-232 data for export to the controlled device.
• SIG-0 device is able to be congured via RS-232 port after entering conguration mode.
• LED indicator to conrm network connection.
• Update rmware via microSD.
Conguration Methods
MicroSD Conguration
The SIG-0 accepts conguration commands from a microSD card on boot.
• Create an empty text le in the root directory of a microSD Card titled ‘AacCong.txt.
• In the AacCong le, add any conguration commands you would normally send via RS-232 in
Conguration mode as a new line (see below).
• Insert the microSD card into the unpowered device, then apply power. The conguration will then be
loaded into ash memory on boot until the microSD is removed.
NOTE: You will not be able to use the device until the microSD is removed.

Conguration Mode
Conguration mode allows the device to be congured over an RS-232 port. The following list of commands
are accepted: See page 2
Commands:
Name Description Format Response
Enter Conguration Enables Cong Mode +++ n/a
Exit Conguration Returns to command
mode
[DEV=254;EXIT] n/a
Query Link Status Ethernet link up/down [DEV=254;NET;LINK?] [DEV=254;NET;LINK=UP]
Query IP Address Returns the SIG-0’s

IP=10.0.0.2]

Server Port
[DEV=254;NET;SERVER;PORT=23] n/a
Reset Defaults Resets the SIG-0
to factory defaults
[DEV=254;RESET;DEFAULT] n/a
Reboot Device Reboots the SIG-0 to
implement change
[DEV=254;REBOOT] n/a
NOTE: All commands except “Enter Conguration” should be terminated by a carriage return. Some set
commands require a device reboot to take effect. Not all commands will have an associated response.
Full command set is available upon request. It is recommended to reboot the SIG-0 after any conguration
changes. This can be done serially, and after reboot, the device will be in Conguration Mode by default.
Communication
Serial Port (RS-232)
The SIG-0 communication bridge has the default device ID 254. It can send and receive serial commands
via RS-232 at 115200 Baud, 8-N-1, and full-duplex. The port may be set for null or straight using the switch
located on the side of the device opposite the microSD port. The port is a modular RJ-45 jack with the
following pinout:
RJ-45 Pinout:
Pin # Function Pin # Function
P1 Orange White - Ground P5 +12V DC Power
P2 Orange - Ground P6 Green - RX or TX
P3 Green White - TX or RX P7 Brown White - Ground
P4 +12V DC Power P8 Brown - Ground
Quick Start Instructions
• Connect the SIG-0 RS-232 port to another RS-232 device with a power injector (e.g. Model 1798).
• Ensure that settings have been congured correctly for both devices. (This can be done serially or via an
SD Conguration update.)
• Connect the SIG-0’s Ethernet port to the device to be controlled and power on both devices.
• Ensure that the Ethernet LEDs are both illuminated, and the power LED is blinking steadily. (The connected
network device will be assigned an IP address of 192.168.0.2 by DHCP, unless congured otherwise.)
• Communicate directly with the end device.

Troubleshooting
No RS-232 communication:
• Ensure connections are fully seated.
• Ensure devices are using the correct protocol settings.
• Ensure the Null/Straight selector is set correctly.
No Ethernet Connectivity Lights
• Ensure connections are fully seated.
• Ensure the End Device is powered on with Ethernet enabled.
• Power cycle all devices to clear out previous TCP connections.
LED periodically blinks fast (no TCP Socket connection)
• Ensure connections are fully seated.
• Ensure both the SIG-0 and end devices have been congured correctly.
• Power cycle all devices to clear out previous TCP connections.*
*Some devices have a limitation on the number of connected TCP clients, and may require a delay period or reboot to clear.

SUPPORT
Firmware Update Process
The SIG-0 communication bridge is updatable via the microSD port on the side of the module:
• Copy new rmware “.FWU” le onto a blank microSD Card (FAT).
• Insert Firmware Update SD into the device with device power disconnected.
• Apply power to device, monitoring the power LED Indicator.
• When power LED indicator returns to a slow blink, update is complete.
• To verify the rmware update, send the rmware version query listed in the Commands List (see above) and
ensure response matches the rmware version expected.
