SIG-1 Communication Bridge
Serial to Internet Gateway

1
Introduction
The SIG-1 Communication Bridge connects an RS-232 to an RS-858 port
to facilitate communication between the RS-485 and your network devices.
This device can be controlled and monitored remotely via Telnet. The SIG-1
mounts directly to a at surface using the mounted anges.
Features
• Serves as a communication bridge between serial devices and network portal devices.
• Enables control of a system from a remote location via Telnet
• Records time-stamped activity logs of all serial trafc for a session
• Measures and reports current draw for the connected system
• Controls switch power on and off to a +12V DC system up to 7A remotely
• Logs any known RS-485 or RS-232 commands for remote log analysis
• Congures information into memory via serial commands or a conguration le on a microSD card.

Conguration Methods
Conguration Mode
The SIG-1 features a conguration mode, which allows the device to be congured over an RS-232 port.
In Conguration Mode, 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
current IP Address
[DEV=254;NET;LINK;IP?] [DEV=254;NET;LINK;
IP=10.0.0.2]
Query Server TCP
Port
Returns currently set
Server TCP Port
[DEV=254;NET;SERVER;PORT?] [DEV=254;NET;SERVER;
PORT=23]
Set Server TCP
Port
Changes the target
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 both the SIG-0 after any conguration
changes. This can be done serially, and after reboot, the device will be in Command Mode by default.
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 above).
• 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: Some congurations will not be retained if the MicroSD card contains contradicting conguration
information, or prerelease rmware F00-V1.0-PRE-5 and older. You will not be able to use the device until
the MicroSD is removed. This is due to the MicroSD conguration having higher priority than the Serial
Conguration.
Firmware Update Process
MicroSD
• 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.

Communication
The SIG-1 Communication Bridge has the default device ID 254. It can send and receive serial commands
via RS-485 at 57600 Baud, 8-N-1, and Half-Duplex; and via RS-232 at 115200 Baud, 8-N-1, and Full-Duplex.
Either port may be set for Null or Straight using the switch located between the RS-232 port and the RS-485 bus.
Both conguration ports utilize a modular RJ-45 jack with the following pinouts:

Quick Start Instructions
• Connect the SIG-1 device to RS-232 and/or RS-485 devices. Connect +12V power out to any devices
that are not connected to, or able to be powered by, the RS-485 bus.
• Connect the SIG-1 device to a known-working network port, then power on the device. The SIG-1 will power
up other devices after a few seconds.
• Communicate with the SIG-1 Device, as well as interact with other devices.
• From the Telnet connection, send a log query command to the SIG-1 to have it respond with the next available
log entry. Repeat until the log is empty.
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-1 Bridge Between RS-232 and Network with Audio
This Display uses audio to attract and communicate. It leverages the MH6 MediaHub’s multiple audio output options
to demonstrate a variety of products. Each of the four audio output jacks can play either digital or analog audio, depending
on the requirements of the device. The ethernet port interfaces with the network to receive commands and output analytics;
with the added capability to control and monitor the system remotely. The sound bar connects directly to an RS-485 port
and is visually highlighted by a lit platform.
