FUNCTIONAL OVERVIEW

The BIM-4xx-RS232 contains all the hardware and firmware required to convert the BIM-4xx-F transceiver

into a user friendly serial interfaced device with an ESD protected RS232 interface. The internal EEPROM

based PIC microcontroller provides all the basic functions required for many applications obviating the need

for further hardware or firmware development. In many applications nothing more than a simple software

driver is required to put your DTE's serial port in control and ready to receive or transmit data.

For the more ambitious users, the BIM-4xx-RS232 is fully user programmable with the optional in-circuit

programming adaptor. This permits reconfiguration of the interfaces internal EEPROM source code.

FUNCTIONAL DESCRIPTION

In standby, the BIM-4xx-RS232 continuously searches the

ether for transmissions. On detection of a preamble or data the

interface signals the host that the channel is busy using the CD

line and opens the RX(data) output to the PC. The host can

then look at the incoming data and respond as and if required.

Data transmission is initiated simply by sending a user

formated data packet from the DTE to the interface. [ Simply

use Windows file send and select the packet you wish to send.

The Windows status bar at the bottom of the screen will give

the progress of the transfer. ]

Upon detection of the start of a data packet (normally the start

of the preamble) the interface automatically switches from

receive to transmit mode and thereafter data is modulated onto

the carrier.

The CD input to the host can be used within the host driver to

prevent collisions with other users.
