CONNECTION WITH THE HOST PC
6.1.
INSTALLATION ON THE ISA BUS
When the RTE-V831-PC is installed in the ISA bus slot of the PC, power (+5 V) 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-V831-PC can be installed in the ISA bus slot according to the following procedure.
<1>
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 5.4. for switch setting.
<2>
Turn off the power to the PC, open its housing, and check the ISA bus slot to be used. If the slot
is equipped with a rear panel, remove the rear panel.
<3>
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.
<4>
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. Check the I/O address of the
board by referring to the applicable manual of the PC or the board.
<5>
When the system turns out to be normal, turn off the PC power again, and put back its housing.
6.2.
STANDALONE USE OF THE BOARD
When the RTE-V831-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 by the RS-232C
interface.
The RTE-V831-PC can be used as a standalone according to the following procedure.
<1>
Get an RS-232C cable for connection with the host and an external power supply (+5 V, 2 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 5.14. and 5.2. for RS-232C cable connection and the power supply
connector, respectively.
<2>
Set the RS-232C baud rate using a DIP switch on the board. See Section 13.2.1. and 14.1.1. for
the switch settings for the Multi and PARTNER monitors, respectively.
<3>
Connect the board to the host via an RS-232C cable. Also connect an external power supply to
the JPOWER jack, 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.
