2. SERIAL CAR D SETUP

The following Serial Card Setup section applies to these PCI cards:

• 3PCIOU1 - one-port, optically isolated PCI serial card

• 3PCIOU2 - two-port, optically isolated PCI serial card

• 3PCIU2 - two-port, non-isolated PCI serial card

• 3PCIU4 - four-port, non-isolated PCI serial card

Any deviations from the procedure for specific models are noted.

PRE-SETUP STEPS

Your serial card has been tested for proper operation before packaging and
shipping. It should be in perfect mechanical and electrical condition upon receipt.

ESD PRECAUT IONS

To ensure a successful installation and setup it is important that you follow the
standard ESD precautions outlined below:

CAUTION:

This is an Electrostatic Sensitive Device.

Use ESD precautions for safe handling.

Before removing the card from the anti-static protective packaging:

• Discharge any static electricity buildup on your body by touching a
large grounded metal surface or the metal chassis on equipment
connected to earth ground by a 3-wire power cord. Use of a
grounding wrist strap is recommended.

• Avoid touching the gold connectors or other parts on the card except

when necessary to set the configuration DIP switches.

• Remove AC power from the computer before inserting the card.

INITIAL CONFIGURATION

The ports in your MIport card are normally pre-configured for RS-232 operation. To
ensure the card is configured correctly for your desired operating mode, you must
check and/or set the three operating mode DIP switches on the card. If you are
configuring for RS-485 Mode you also may have to set up the RTS Control
parameter in the device driver.

NOTE: For information on Setting Driver Options, refer to Chapter 4.

OVERVI EW OF O PERATIONAL MODES

RS-232 MODE

In RS-232 Mode, MIport seri al ports function as buffered standard PC serial ports and
operate as DTEs (Data Terminal Equipment). RS-232 interfaces are commonly us ed for
communications with modems , serial printers, and computer controlled devi ces such as
securit y equipment, bar code scanners and point-of-sale devices.

For most MIport models, RS-232 Mode supports eight single-ended signal lines and
Signal Ground (GN D ) including Tr ansmit (TD), Receive (RD) and s ix hardware
handshake lines (DTR, DSR, RTS, CTS, DCD, RI).

RS-422 MODE

In RS-422 Mode, MI port serial ports provide two s ets of differential signal pair s (TD and
RD) and Signal Gr ound for each port . The RS-422 standard uses balanced di fferential
drivers and receivers for each signal. This facilitates greater communication distances
than unbalanc ed systems suc h as R S -232. In RS-422 mode, the transmit ter and receiver
are always enabl ed (TX ON, RX ON).

RS-422 operation i s suitable f or interconnecting a computer and one device for f ull duplex
(point-to-point) bi-directional communication, or a computer and several devic es for
unidirectional (point-to-multi-points) communication. RS-422 interfaces are commonl y
used for video editing/control, camera control, electronic signage, television
studio/satellite dish control, performance lighting and audio equipment control.

RS-485 MODE

In RS-485 Mode, MIport cards provide RS-485 interfaces which operate with the same
signals and s ignal levels as RS -422. R S-485 interfaces differ from RS-422 in that they
allow multiple devices to share the same communi cation link using half duple x (2-wire) or
full duplex (4-wire) connections. Since it is possible to have mor e than one transmitter
connected to the media, transmitters must be enabled only while sending data, and tri­stated at all other times so other devices can use the wire pair . MIport cards aut om atically
enable the tr ansmitter at the appropriate t ime using Automat ic Send Data Control, based
on the contents of the output buffer. When the buffer has data to send, the transmitter is
enabled (TX SD). When all data i n the buffer has been s ent, the trans m itter is disabled
and tri-st ated to a high impedance state.

In half-duple x operation, the receiver is di sabled during transmit (RX ), and enabled
when not transmitting. In f ull-duplex operati on the receiver i s always enabled (RX O N ).
Since RS-485 transmitters are tri-stated when not transmitting, the receive inputs must be
biased to ensur e the media float s in the Mark stat e so that the first Space state is
detected cor rectly at the start of the next transmission.

These serial cards incorporate the necessary biasing to accommodate up to 32 standard

nodes. (Typical input resistance (Rin) for each load is 12kΩ). Provisions are made for

custom biasing and/or term ination.

NOTE: For more information on RS-485 Mode, refer to Chapter 7.

OPERATING MODE SELECTION

The hardware address and IRQ for the serial card is set by the Windows Operating
System using driver information files and the Plug and Play OS.

The Operating Mode is set using DIP switches, Device Manager Driver Settings and
by your cable connections and software. Each port on a MIport card has an
associated DIP switch to set its operating mode. The port number associated with
the DIP switch is clearly silk-sc reened on the print ed circ uit b oar d.

NOTE: For DIP Switch locations on card models, refer to Appendix A.

Figure 4: RS-232/422/485 DIP Switch Settings

DIP Switch 1 (RS-232/422/485 Ports)

The top DIP switch (1) configures the port for RS-232 or RS-422/485 operation. This
switch is the only one that is required to be set for RS-232 operation. The positions of
switches 2 and 3 do not matter when switch 1 is set for RS-232 operation.

DIP Switch 2 (RS-232/422/485 Ports)

The middle DIP switch (2) configures the port for RS-4 85 or RS -422 operat ion. For
RS-422 operation (which uses two wire pairs and sends point-to-point or point-to­multi-points) the transmitter can be enabled all the time. Placing the middle DIP
switch in the TX ON position accomplishes this.

Multi-Interface PCI Serial Cards

7

For RS-485 operation, the middle DIP switch is placed in the TX SD position. In this
position the transmitter is only enabled when data is being sent. The transmitter is
tri-stated when not sending data, allowing other transmitters on the communications
line to transmit without interference.

DIP Switch 3 (RS-232/422/485 Ports)

The bottom DIP switch (3) configures the port for half-duplex (two-wire) RS-485
operation or full-duplex (four-wire) RS-422/RS-485 operation. Placing the bottom
DIP switch in the RX ON position configures the port for four-wire operation. In this
mode the receiver is continuously enabled, allowing it to receive all data on the
communications line. Since the transmitter sends data on the other wire pair, the
port does not receive its own transmissions.

Placing the bottom DIP switch in the RX position configures the port for two wire
operation. In this mode the transmitter and receiver are connected to the same wire
pair. The receiver is disabled when its transmitter is sending, preventing the port
from receiving its own data.

SETTING THE DIP SWITCHES ON R S-422/485 ONLY PORTS

Ports that do not inc lude RS-232 operation use double DIP switches rather than
triple DIP switches. These DIP switches operate the same as the two bottom DIP
switches in the RS-232/422/485 ports.

DIP Switch 1 (RS-422/485 Only)

The top DIP switch (1) configures the port for RS-485 or RS-422 operation. For RS­422 operation (which uses two wire pairs and sends point-to-point or point-to-multi­points), the transmitter can be enabled all the time. Placing the middle DIP switch in
the TX ON position accomplishes this.

For RS-485 operation the middle DIP switch is placed in the TX SD position. In this
position, the transmitter is only enabled when data is being sent. The transmitter is
tri-stated when not sending data, allowing other transmitters on the communications
line to transmit without interference.

DIP Switch 2 (RS-422/485 Only)

The bottom DIP switch (2) configures the port for half-duplex (two-wire) RS-485
operation or full-duplex (four-wire) RS-422/RS-485 operation. Placing the bottom
DIP switch in the RX ON position configures the port for four-wire operation. In this
mode the port’s receiver is continuously enabled, allowing it to receive all data on
the communications line. Since the port’s transmitter sends data on the other wire
pair the port does not receive its own transmissions.

Placing the bottom DIP switch in the RX position configures the port for two-wire
operation. In this mode, the port’s transmitter and receiver are connected to the
same wire pair. The receiver is disabled when its transmitter is sending, preventing
the port from receiving its own data.
