Chapter 2 CONFIGURATION
2.1 Introduction
Chapter 2 describes the software and hardware configuration required to properly integrate the FlexCom104-GPS
into a PC/104 Stack
The FlexCom104-GPS has configuration jumpers for I/O address, IRQ, mode of operation, and module
voltage.
2.2 Software Configuration
A utility is available from the Tri-M website (
) to configure the FlexCom104-GPS under
Windows. Under Linux, setserial can be used to configure the FlexCom104-GPS.
The following command would configure the Linux kernel to use Module 1 as /dev/ttyS2 correctly with
the default settings.
setserial /dev/ttyS2 port 0x100 irq 7 uart 16850 baud_base 921600 spd_vhi
2.3 IRQ Interrupt Configuration
The FlexCom104-GPS can be configured for IRQ5, IRQ7, IRQ10, IRQ11 and IRQ12 by the installation of jumper
shunts on JP1 as per Table 1.
