The jumpers for enabling the termination resistors are places beside the connector at the board's bracket. By
closing the pins with a jumper, a termination resistor of 120 ohms gets placed across the receive lines of the
port.
Serial IO Hardware Setting (4-PORT / 3)
To install a Moxa Smartio/Industrio 4-port board in a VLC as the third serial board, the IO port and IRQ
settings of the board must be changed to 0x380 / IRQ 11 by means of the DOS based configuration utility
shipped with the board.
The following steps describe how to install the card into a running VLC.
1. Shut down the VLC, switch it off.
2. Open the housing.
3. Install the board in a free slot.
4. Install the jumper at the rounded corner of the board (it's the only jumper on this board).
5. Connect a VGA computer monitor and a keyboard to the VLC.
6. Switch on the unit.
7. Press 'F5' when the VLC asks to do so. The VLC only waits for 3 seconds at this point, so keep an
eye on the messages on the screen.
8. At the DOS prompt, enter MOXA
9. The configuration program first asks to select the card type (choose 'Smartio'), then it asks for the
board address. Enter 'A700'.
10. Set the port addresses and IRQs according to the table shown below:
IO Port 380
388
390
398
IRQ
11
