NBEK Controller As 1200 Baud Modem

The Narrow band Evaluation Kit (NBEK) IC can be used as 1200baud half-duplex serial modem

suitable for narrow band receivers, transmitters and transceivers (or any RF modules with >5kbps data

rate). It takes care of preamble, synchronisation, bit

balancing and error checking and enables a

transparent radio data link to be established

between radio devices

This is a half duplex unit, so collisions between

transmitted and received packets must be dealt

with by the user.

Provided no two devices attempt to transmit

simultaneously no further restrictions on data

Figure 1: NBEK-000-DIL

transmission need be made, as all transmit timing,

valid data identification and data stream buffering is conducted by the unit. Synchronisation and

framing words in the packet prevent the receiver outputting garbage in the absence of wanted RF

signal or presence of interference.

Supports 1200 baud asynchronous data: 1 start bit, 8 data bits, 1 stop bit.

With typical microcontrollers and UARTs, direct connection is usable as shown on figures 2 & 3.

To connect to a true RS232 device, inverting level shifters must be used (MAX232 type are ideal, but

simple NPN/PNP transistor switches often suffice as used in the application circuits figures 4 & 5).

Features

ꢀ

Operating voltage (temperature): 5V for standard version (-40°C to +85°C)

Maximum usage of the range capability of an RF module

Adequate preamble to settle data slicer in the receiver

Extra wake up preamble to allow for transmitter power up time requirements

Differential Manchester encoding of address, data and checksum

Synchronisation codes and checksum to reduce false triggering on noise

Suitable to be used with Narrow Band FM radio modules

Serial modem baud rate at 1200bps (half-duplex)

Addressable point-to-point

Applications

ꢀ

PDAs, organisers & laptops

Handheld / portable terminals

EPOS equipment, barcode scanners

In-building environmental monitoring and control

Remote data acquisition system, data logging

Fleet management, vehicle data acquisition
