· PCI(*2)
· IDE connector shape signal input and output connector
· Connector for logic analyzer (*3)
· Serial port
· Rotary switch
· DIP switch
· Push switch
· LED

*1 A maximum of 698 signals can be connected to the functional modules.
A maximum of 698 signals can also be connected between adjacent functional modules.
*2 By mounting a commercial PCI bridge card, the PCI bus on a personal computer can be extended onto the B-1,
and it is possible to control the functional module from the personal computer.
*3 Probes for a total of 32ch of multi-purpose logic analyzers can be connected to the B-1.
Also, P6860 low capacitance active probes manufactured by Tektronix Inc. can be connected.

Regarding clock wiring:
The B-1 clock wiring includes the following two systems.

1. Pear-to-Pear clock wiring between adjacent functional modules
Clock wiring between adjacent functional modules mounted on B-1.
The clock on one functional module is transmitted, and the clock is received by the other functional module.
With these clocks, 200MHz data transmission clocks can be achieved.

2. Common clock wiring between functional module block units
Wiring to provide clock from B-1 to functional module block units.
A common clock can be transmitted from B-1 to a maximum of 4 functional modules.
If a PCI bridge is mounted on the B-1, the PCI clock provided from the personal computer can be transmitted to functional modules.

Regarding the PCI bridge function:
By mounting a PCI bridge card on the B-1, the PCI bus on a personal computer can be extended onto the B-1.
A commercial PCI bridge card is included with B-1 as standard configuration.

Regarding FPGA configuration:
The following 2 methods can be used for configuring FPGAs on B-1.

1. Method of configuring each functional module on B-1
A JTAG port is mounted on the B-1, and furthermore the JTAG chain connection is provided, so that each functional module can be configured at once.
Also, the JTAG chain can be switched ON/OFF in functional module units.

2. Method of configuring on functional modules
An FPGA dedicated configuration ports and JTAG port are provided so that configuration can be carried out on each functional module.
Also, the commercial FlashLink (ROM for configuration) product is included as standard.
* Writing data from FlashLink to an FPGA is completed in a few seconds, so this results in shorter debugging time.

Regarding power supply:
The necessary power supply is provided to each functional module from B-1 via a dedicated power supply harness.
In providing power, boot timing is controlled by the power supply ON/OFF control circuit of the reset circuit.

Regarding the reset circuit:
On the B-1, a PLD onto which the reset control circuit is written is mounted as a reset module.
Using the reset module, each power supply module is controlled ON/OFF, and individual functional modules
or all mounted functional modules can be reset.

Types of chassis and external power supply devices:
There are 2 types of chassis for supporting the B-1 that can be selected when placing an order.
1. Acrylic chassis
Chassis made of transparent acrylic resin.
2. Metal chassis
Chassis made of metal.

It is necessary for customers using an acrylic chassis to provide an external power supply (DC +5V output) (*4).
Customers using a metal chassis do not need to provide an external power supply.
An AC 100V power supply can be connected to the metal chassis.

*4 We can provide it for you as your request.
