Installation
Note: In one system, you can install two of these serial cards. Follow the instructions
below to designate each card as either card number 1 or card number 2. Install the cards
one at a time, starting with the card you want to be designated number 1.
Installing the Card
1. Make sure that your system is unplugged and you are grounded.
2. PCI2S422ISO: If you are installing two cards in the same system, you must
differentiate between the cards by using the dip switch on the card. You use dip
switch 1 and 2 to set the card number
. When both dip switch 1 and 2 are in the ON
position, the card will be designated card number 1. When dip switch 1 is OFF and
dip switch 2 is ON, the card will be designated card number 2.
You use dip switch 3 and 4 to set each port to either RS-422 or RS-485 mode . Dip
switch 3 corresponds with Port A (marked on the card), dip switch 4 corresponds
with Port B. When the dip switch is in the ON position, the port will operate in RS-
422 mode. When the dip switch is in the OFF position, the port will operate in RS-485
mode.
PCI4S422ISO: If you are installing two cards in the same system, you must
differentiate between the two cards by using the JP1 jumper (located near the end
of the card). The card with the jumper ON will be card number 1. The card with the
jumper OFF will be card number 2.
Configure each port (labeled A to D) to be either an RS-422 or an RS-485 port using
the dip switches located on the card.
When the dip switch is in the upper or On
position, that port will operate in RS-422 mode. When in the lower or Off position,
the port will operate in RS-485 mode.
2. Remove the cover of your system (see your computer's user manual for details, if
necessary) and gently turn your computer onto its side.
3. Locate an empty PCI slot (usually white in colour) and remove the metal plate that
covers the rear bracket. You may need a Phillips screwdriver to perform this step.
Hang on to the screw!
You will need it to secure the card later.
4. Gently insert the card into the empty slot, making sure it is firmly seated.
5. Secure the card in place using the screw you removed in Step 3 and put your
computer case back on.
6. PCI4S422ISO only: Plug the 37-pin end of the serial cable into the port on the card.
7. Turn the computer on.
