BV101-4	USB to TTL 5V logic Converter	Datasheet	£12.32
	This is a USB to serial converter that is primarily designed for the BV system but could be used for any USB – serial application. The output is TTL 5V logic levels.		Qty:
	Quantity discounts price each 2 £11.32

Up to 100mA can be taken from the USB via an on board low drop out voltage regulator. This regulator also provided short circuit protection to the USB host system.

The board utilises the FT232BM chip and free drivers are available from www.ftdichip.com The Virtual COM port (VCP) driver should be used.

There are three output connectors on the board, two are duplicated for connecting multiple IASI devices and the third provides the control signals, DTR, RST, etc. This third connector is supplied with the 5 way pinhead connector but without it soldered in place giving the user maximum flexibility.

Connection diagram, the socketed output is dual-ganged together so that two IASI devices can conveniently share the same bus. The control signals are on a separate connector that has a loose pinhead supplied, this can optionally be soldered in place by the user.

Specification

BV201	RS232 to TTL 5V logic Converter	Datasheet	£9.50
	This is a converter to enable a PC Com port to be connected to 5V equipment, it will convert the 12V RS232 signals to 5V and 0V so that an interface can be made to microcontroller or similar equipment.		Qty:
	Quantity discounts price each 3 £7.83, 10 £6.60, 100 £5.47

This is a converter to enable a PC Com port to be connected to 5V equipment, it will convert the 12V RS232 signals to 5V and 0V so that an interface can be made to microcontroller or similar equipment.

It has a D connecter at one end designed to take a standard RS232 serial cable. At the other end is an 8 way pin connector.

This board requires a 5V power source that under normal circumstances can be obtained from the host device. The plus and minus 12V signals are converted to TLL and vice versa.

Specification

• RS232 Input to 9 pin D connector
• TX, RX, CTX, RTS and DTR signals available
• 5V
• Size: 35mm x 33mm x 12mm high
