Chapter 1 INT ODUCTION
General Description
The FlexCom104-GP has the following restrictions:
•Both Universal ocket modules supplied with 5V. No support for 3.3V socket modules
•Only Multitech Universal ocket wireless modules supported.
The FlexCom104-GPS is a communications platform capable of supporting two of the Multitech
Universal Socket compatible devices. Embedded in the FlexCom104-GPS is a quad UART
(ST16C554DIQ64) to provide communications to the two Universal Sockets, a mounting point for the
FV-4H GPS and an additional serial port. The ST16C554DIQ64 is an enhanced quad UART with 16
byte FIFOs on both transmit and receive.
The PC/104 bus provides access to quad UARTs. One UART port is connected to the auxiliary serial port.
The FlexCom104-GP supports wireless Multitech modules, with mounting holes.
In this document, the term “serial port” refers to a UART based communications port that is available on pin headers.
Features
•Two Multitech compatible Universal Sockets
•One RS-232 serial port on a 2x5 pin 2mm header with a MAX3250 ±50V isolated interface
•One mounting location for an FV-4H GPS
•PC/104 interface to high speed quad UART
•Selectable I/O address & IRQ
•Supports 5V Multitech modules
•GPS 1 Pulse per Second LED
•GPS 1 Pulse Per Second line fed to Carrier Detect line for time synchronization as per the standard PPSKit
configuration

Chapter 2 CONFIGU ATION
2.1 Introduction
Chapter 2 describes the software and hardware configuration required to properly integrate the FlexCom104-GP
into a PC/104 tack
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 (www.tri-m.com) 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-GP can be configured for IRQ5, IRQ7, IRQ10, IRQ11 and IRQ12 by the installation of jumper
shunts on JP1 as per Table 1.

2.5 ower Source
Universal ocket modules are available in 3.3V and 5V models. The FlexCom104-GP supports only 5V modules.
The 5V power for the FlexCom104-GP must be supplied over the PC/104 bus.
2.6 Inserting the Module
There are two Universal ocket module locations (Module1 and Module2) and modules will only fit in the
FlexCom104-GP in one orientation. Attempting to insert the module in any other orientation may damage the
module or the FlexCom104-GP .
Insert a module by placing the largest group of pins in their sockets at once, then align the rest of the pins, and apply
pressure evenly to the module until it settles in the socket.
The antenna cable will need to be routed from the Wireless Modem module to the outside of the enclosure for the
antenna to get a good signal.
2.7 Securing the Module
Wireless modules use two mounting screws to hold them into the socket. Two 4-40 1/8” countersunk
screws can be used with 0.312” female standoffs to secure the module.

2.8 Connecting an FV-4H G S
A GP antenna must be connected to the MA connector on the FlexCom104-GP for the FV-4H GP to operate.
2.9 Connecting an External Serial ort
The serial port has the same pin out (see Table 3.6.1) as a standard IDC serial connector, however it
has 2mm pin spacing.
