Introduction

Moxa’s UC-8580 is an innovative computing platform designed
specifically for transportation applications.
The UC-8580 is available with one of two different types of antenna
connector. The SMA model supports all SMA type connectors. The
QMA model supports TNC connectors for GPS and QMA connectors
for Wi-Fi/cellular modules, and has four slots for installing wireless
modules*. Three slots support 4G/LTE modules, and one slot supports
a Wi-Fi module. Each 4G/LTE module has two SIM card slots, which
can be used to enable redundant cellular network communications
or geo-fencing SIM card selection by leveraging the built-in Wireless
Manager, a Moxa software utility for cellular and Wi-Fi management.
The UC-8580 uses an open platform based on Debian 8 with Linux
Kernel 4.1, allowing solution providers to manage software packages
via Debian’s APT (Advanced Packaging Tools), or develop software
applications with Moxa’s API Library and GNU C Library.
The UC-8580’s single-sided I/O design is ideal for vehicle applications,
which typically do not have a lot of room for installing communications
devices. The UC-8580 also has an access panel on the front side,
allowing users to install or change wireless modules, SIM cards, or
mSATA cards without removing the entire unit from the wall after being
mounted.
The UC-8580 can be used as a communication-centric computing
platform for the following applications:
• Vehicle-to-ground communication gateway
• TCMS T2G (train-to-ground) gateway
• Mobile condition monitoring unit
• Ethernet Consist Network T2G gateway
• Onboard wireless automated fare collection unit
