SIG-0 Mini-Gateway

Communication Bridge / Network Adapter

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

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.

Example System:

SIG-0 Bridge Between RS-232 and Network

This display utilizes a SIG-0 communication bridge to connect a media device with an RS-232 to a network.

Commands stored on the SIG-0 are used to automate run times for the device.

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.
