Chapter 1 – Developer’s Kit and Developer’s Board
Overview
Welcome
Thank you for using the MultiConnect open communications gateway embedded (MultiConnect™ OCG-E)
developer’s kit. This guide describes how to use the kit to design, develop and test custom applications for your
business. This chapter describes the gateway product, the developer board, and other kit contents. It also includes
safety notices that you can include in your product’s documentation, if desired.
Product Overview
The MultiConnect™ OCG-E helps you quickly create custom applications. The gateway is made up of an open Linux
development environment and fully certified hardware. The gateway includes multiple interfaces (serial, USB,
Ethernet and SD card) and internal peripherals (including a cellular modem and a GPS receiver) in one, applicationready end user solution. This gateway is ideal for companies with hardware and software competencies and
provides maximum design flexibility.
Applications that require device networking capability can now reside directly on select Multi-Tech gateways. This
product brings together a cellular hardware development kit, Multi-Tech’s CoreCDP Linux distribution and a
complete Linux build environment, allowing you to quickly create custom applications. The MultiConnect OCG-E
gateway provides a flexible, quick and cost-effective way to bring your solution to market.
For detailed information about the CoreCDP Development Platform, please visit the Multi-Tech website at:
http://www.multitech.net/
The developer’s board is available without a cellular modem. You can also develop your solution by choosing an
MT100EOCG model that uses the standard you desire:
GPRS, by selecting the MT100EOCG-G2 model
HSPA or HSDPA, by selecting the MT100EOCG-H5 model
EV-DO Rev A, by selecting the MT100EOCG-EV3 model
For complete ordering details, see the section “Product Ordering Options” in this manual. An illustration of an
MT100EOCG gateway follows. Your gateway may look slightly different, depending on the type of model you select
(-G2, -H5, -EV3 or gateway without cellular modem).

Developer’s Kit Contents
Use the MultiConnect OCG-E Developer’s Kit MT100EOCG-DK and the models described in this guide to develop
and evaluate your products and applications. This kit contains:
Four screws for mounting gateway to developer’s board
One Multi-Tech screwdriver
Developer’s Board Components
The developer board is an auxiliary board that helps you develop and debug products that use an embedded
MT100EOCG gateway. Using the developer board, you can connect the embedded MT100EOCG gateway to your
device.
The developer board provides multiple interfaces, such as USB, serial, Ethernet and SD card. The test points of key
signals are led out on the developer board. In addition, the board is designed with switches or pins of commonly
used signals such as the reset signal and the enable signal for converting the working state of the gateway. You can
use the board to test the performance of the gateway.
You can implement both the wired connection test and the wireless connection test (connect the gateway model
to the antennas). You can also test the signal points when you maintain and repair the gateway.
The board provides two, universal socket connectors that give you the option to develop and test your solutions
that might include Wi-Fi or other types of technologies.
9ADC0IAnalog-to-Digital converter Input. (0 to 3v).
10ADC2IAnalog-to-Digital converter Input. (0 to 3v).
11GPI7IGeneral-Purpose Input.
12GPI9IGeneral-Purpose Input.
13TDOOJTAG Data Output.
14NTRSTI/OJTAG Reset (Active Low).
15GPS-PPSOGPS PPS - Pulse Per Second.
16GPS-TXOGPS - Transmit Data.
17-DTR_1IData Terminal ready. The DTE uses the -DTR_1 line to signal to the
module that it is ready to accept communication. The signal is also
used to signal to the module to terminate communication (hangup).
18-RXD_1OReceived Data. The gateway uses the RXD1 line to send data to
the DTE and to send gateway responses to the DTE. In command
mode, -RXD1 data presents the gateway responses to the DTE.
19-TXD_1ITransmitted Data. The DTE uses the -TXD1 line to send data to the
gateway for transmission or to transmit commands to the
gateway. The DTE holds this circuit in mark state when no data is
being transmitted or during intervals between characters.
20-RTS_1I"Request to Sent (Active Low). -RTS1 signal is used for hardware
flow control. -RTS1 input ON (low) indicates that the DTE is ready
to send data to the device. In the command state, the device
ignores -RTS1.
21-DCD_1OData Carrier Detect (Active Low). DCD is controlled by processor.
You can program how DCD is set.
22-CTS_1OClear to Send (Active Low). -CTS_1 is controlled by the gateway to
indicate whether or not the gateway is ready to receive data from
the DTE on the -TXD_1 input signal.
23GPO4OGeneral-Purpose Output.
24GPO3OGeneral-Purpose Output.
25GPO2OGeneral-Purpose Output.
26GPO1OGeneral-Purpose Output.
2727 GND Logic Ground.
28-RESETIDevice Reset (with pull-up). The active low -RESET input resets the
device logic. -RESET is tied to VCC through a time-constant circuit
for proper reset of the device if -RESET is not being externally
driven.
29BATT-INIBattery Backup Input 3V.
30USBH_DPI/OUSB Host Data Positive. Positive pin of USB data pair.
