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. Configure and store
data directly on the device via the integrated microSD port or serial commands. The device can be mounted
directly to a flat surface using the mounted flanges.
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, configure, and store information via serial commands or a configuration file on a microSD card.
• Packages incoming RS-232 data for export to the controlled device.
• SIG-0 device is able to be configured via RS-232 port after entering configuration mode.
• LED indicator to confirm network connection.
• Update firmware via microSD.
Configuration Methods
MicroSD Configuration
The SIG-0 accepts configuration commands from a microSD card on boot.
• Create an empty text file in the root directory of a microSD Card titled ‘AacConfig.txt.
• In the AacConfig file, add any configuration commands you would normally send via RS-232 in
Configuration mode as a new line (see below).
• Insert the microSD card into the unpowered device, then apply power. The configuration will then be
loaded into flash memory on boot until the microSD is removed.
NOTE:
You will not be able to use the device until the microSD is removed.
