1.1.

INTRODUCTION

Unlike traditional commercial modems, the Peek LPM-14-E is designed to perform its data
transmission functions in virtually all types of environments. From solar-powered roadside equipment
where the temperature could dip well below freezing to the blazing heat of an industrial production line, the
LPM-14-E functions with equal reliability. This is possible because the LPM-14-E is housed in a rugged,
enamal-coated aluminum chassis which protects both the delicate electronics and its signal integrity. A
very efficient standby mode is also implemented in the hardware of the LPM-14-E to take advantage of the
frequent idle periods typical in all remote data retrieval systems. Additionally, only wide temperature range
components are used to build the LPM-14-E which are then conformal coated, allowing it to function in the
harshest environments.
The LPM-14-E comes with a rich set of features that rival that of our competitors. With its power
consumption of less than 100mW in standby mode and only 3.6 Watts while active, the LPM-14-E is
suited for systems that are powered by solar energy. It will reliably communicate with remote modems at
temperatures ranging from -40C to +80C and up to 95% non-condensing humidity. The LPM-14-E is fully
compatible with the CCITT V.32bis, V.32, V.22bis, V.22, Bell 212A and Bell 103, allowing it to
communicate at speeds from 300 to 14,400 baud with all other CCITT compliant modems on the market.
It also features MNP2-4/V.42 Error Correction and MNP5/V.42bis Data Compression protocols, allowing
the LPM-14-E to perform reliable compressed data transmission at a maximum speed of 19200 baud.
