Mini Gateway USB (MGU)
DATASHEET
GATEWAY OVERVIEW
The MGU provides a direct interface to the on-board ModFLEX module through the USB interface.
Command and control of the module is achieved through the standard host protocol commands. See
the module specific Host Protocol Document for more details. These commands can also be exercised
though the ModFLEX Test Tool Suite.
USB Controller
The Mini Gateway USB uses a FTDI FT232 USB-to-Serial bridge. The FT232 is a highly-integrated
USB-to-UART bridge controller. The FT232 includes a USB 2.0 full-speed function controller, USB
transceiver, oscillator, EEPROM, and UART with full modem control signals. Please refer the FTDI web
site for the latest drivers for the FT232 ( www.ftdichip.com ).
ModFLEX Module
The ModFLEX module can be any one of LSR’s radi o transceiver modules that are a member of the
ModFLEX family of products. This includes the SiFLEX02 and ProFLEX01 modules. All ModFLEX
modules are pin compatible and drop into the same PCB footprint to allow maximum flexibility.
There are three LEDs that are used to provide status to the user:
?
?
?
Green – Indicates that the ModFLEX module is operational (heartbeat).
Yellow – Indicates that there is activity on the host interface.
Red – Indicates RF activity.
Antenna
The MGU is equipped with a high performance external antenna that can be arranged in different
orientations to accommodate various mounting configurations. The environment the module is placed
in will dictate the range performance. The non-ideal characteristics of the environment will result in the
transmitted signal being reflected, diffracted, and scattered. All of these factors randomly combine to
create extremely complex scenarios that will affect the link range in various ways.
It is also best to keep some clearance between the antenna and nearby objects. This includes how the
module is mounted in the product enclosure. Unless the items on the following list of recommendations
are met, the radiation pattern can be heavily distorted.
?
?
Keep metal objects as far away from the antenna as possible.
Do not embed the antenna in a metallic or metalized plastic enclosure.
