4.2. INSTALLATION ON THE ISA BUS
When the RTE-V821-PC is installed in the ISA bus slot of the PC, power (+5V) is supplied from
the ISA bus to the board. In addition, the ISA bus can be used for communication with the
debugger, so programs are down-loaded at high speed.
The RTE-V821-PC can be installed in the ISA bus slot according to the following procedure.
•
Set the I/O address of the PC using a DIP switch on the board. Be careful not to specify
the same I/O address as used for any other I/O unit. See Section 4.1 for switch setting.
‚
Turn off the power to the PC, open its housing, and confirm the ISA bus slot to be used.
If the slot is equipped with a rear panel, remove the rear panel.
ƒ
Insert the board into the ISA bus slot. Make sure that the board does not touch any
adjacent board. Fasten the rear panel of the board to the housing of the PC with screws.
„
Turn on the power to the PC, and check that the POWER-LED on the board lights. If the
LED does not light, turn off the PC power immediately, and check the connection.
If the system does not start normally (for example, if an error occurs during installation of a
device driver), it is likely that the set I/O address is the same as one already in use.
Reconfirm the I/O address of the board by referring to the applicable manual of the PC or
the board.
…
When the system turns out to be normal, turn off the PC power again, and put back its
housing.
4.3. STANDALONE USE OF THE BOARD
When the RTE-V821-PC is used as a standalone rather than being installed in the PC, it
requires an external power supply. In addition, communication with the debugger is supported
only by the RS-232C interface. This configuration is useful when the host debugger used with
the board is not one in the PC/AT or compatible as well as when the board is used for hardware
confirmation and expansion.
The RTE-V821-PC can be used as a standalone according to the following procedure.
•
Get an RS-232C cable for connection with the host and an external power supply (+5 V, A)
on hand. Especially for the power supply, watch for its voltage and connector polarity.
In addition, attach spacers to the four corners of the board, so it will not pose any problem
wherever it is installed. See Sections 3.8 and 3.2 for RS-232C cable connection and the
power supply connector, respectively.
‚
Set the RS-232C baud rate using a DIP switch on the board. See Section 4.1 for switch
setting.
ƒ
Connect the board to the host via an RS-232C cable. Also connect an external power
supply to the JPOWER connector, then check that the POWER-LED on the board lights.
If the LED does not light, turn off the power immediately, and check the connection.
