Serial Card Setup
Chapter 2: Serial Card Setup
The following Serial Card Setup section applies to the following PCI cards:
•3PCIOU1 one port optically isolated PCI serial card
•3PCIOU2 two port optically isolated PCI serial card
•3PCIOU4 four port optically isolated PCI serial card
•3PCIU2 two port non-isolated PCI serial card
•3PCIU4 four port non-isolated PCI serial card
•3PCIU8 eight 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 Precautions
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 will have to 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: Refer to Chapter 4 for information on Setting Driver Options.

Serial Card Setup
Overview of Operational Modes
RS-232 Mode
In RS-232 Mode MIport serial ports function as buffered standard PC serial ports and operate as DTEs (Data Terminal Equipment). RS-232 interfaces are commonly used for communications with modems, serial printers, and computer-controlled devices such as security 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 (GND) including transmit (TD), receive (RD) and six hardware handshake lines (DTR, DSR, RTS, CTS, DCD, RI). The only exception to this is the MIport Model 3PCIOU4 card, which supports TD, RD, RTS, CTS and GND.
RS-422 Mode
In RS-422 mode MIport serial ports provide two sets of differential signal pairs (TD and RD) and signal ground for each port. The RS-422 standard uses balanced differential drivers and receivers for each signal. This facilitates greater communication distances than unbalanced systems such as RS-232. In RS-422 mode the transmitter and receiver are always enabled (TX ON, RX ON).
RS-422 operation is suitable for interconnecting a computer and one device for full duplex (point-to-point) bi-directional communication, or a computer and several devices for unidirectional (point-to-multipoints) communication. RS-422 interfaces are commonly 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 signal levels as RS-422. RS-485 interfaces differ from RS-422 in that they allow multiple devices to share the same communication link using half duplex (2-wire) or full duplex (4-wire) connections. Since it is possible to have more than one transmitter connected to the media, transmitters must be enabled only while sending data, and tri-stated at all other times so other devices can use the wire pair. MIport cards automatically enable the transmitter at the appropriate time using Automatic 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 in the buffer has been sent, the transmitter is disabled and tri-stated to a high impedance state.

Serial Card Setup
In half-duplex operation, the receiver is disabled during transmit (RX 
), and enabled when not transmitting. In full-duplex operation the receiver is always enabled (RX ON). Since RS-485 transmitters are tri-stated when not transmitting, the receive inputs must be biased to ensure the media floats in the Mark state so that the first Space state is detected correctly 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 termination.
Note: For more information on RS-485 Mode refer to Chapter 6
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 screened on the printed circuit board.
Note: Refer to Appendix x for DIP switch locations on various MIport cards.

Figure 5. 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-485 or RS-422 operation. For RS-422 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 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 RS-422/485 Only Ports
The 3PCIOU4 MIport card provides a combination of RS-232/422/485 and RS-422/485 only ports. Ports that do not include 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 RS232/422/485 ports
