This manual describes diagnostic capabilities and some troubleshooting information for the RediGate industrial data gateway products, including:

The Elecsys gateway products are multi-function communication interface devices, which can be configured for many different types of applications such as protocol conversion, data concentration, and report-by-exception of data.  Diagnostics are available to diagnose communication problems and to verify proper operation of every aspect of the system.

Some features described herein may only be available on more recent software releases of the gateway device. Variations between different product models will be distinguished where needed.

Configuration Requirements

This document refers to the gateway configuration or "ACE configuration," which is created and uploaded to the RediGate using the ACE Configuration Editor. See the article Installing ACE and the page for documentation on using ACE to configure the RediGate.

Serial Diagnostics 

The RediGate typically uses COM0 for a local serial diagnostics port. When the RediGate is powered on, it sends startup messages to its COM0 port.  A terminal program must be set up with communication parameters configured for a baud rate of 115,200, no parity, 8 bits, 1 stop bit.

RediGate 100 series: COM0 is available via the Micro-USB port on the front of the device. See the article Installing USB Driver for installing the required USB serial driver in Windows.

RediGate 400 series: COM0 is a DB-9 RS-232 port. Pinout is: pin 3–TX, pin 2–RX, pin 5–GND (use a null modem serial cable to a configuration computer).

In order to use the serial diagnostics (MMI or Linux console) after startup, the following objects are required in the RediGate configuration:

Network Diagnostics

Diagnostics are available through a network connection via a secure shell (SSH) login, typically using IP port 22.

In order to use network diagnostics, the following things are required in the RediGate configuration: 


(NOTE: Some cellular account activations do not allow SSH connections to be made to cellular device. Check with your account provider for information on this.
