Jumper settings This section tells how to set the jumpers to configure your card. It gives the card default configuration and your options for each jumper. How to set jumpers You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.
Card installation Warning! Turn off your PC’s power supply whenever you install or remove the PCI communication card or its cables. Static electricity can easily damage computer equipment. Ground yourself by touching the chassis of the computer (metal) before you touch any boards. See the static warning on page 6 1. Turn off the computer. Turn the power off to any peripheral devices (such as printers and monitors). 2. Disconnect the power cord and any other cables from the back of the computer.

All Ports Stop stop test on all ports Clear Message clear messages on Message Logo area and the Rx length information on the Performance Listing area Each Com Port tab represents a specific port you have selected for test and configuration. On the tab, you can see the Transfer Mode, Port Status, and Message Logo area. Transfer Mode You can specify the transfer mode to be Normal, loopback (active) and loopback (passive) Normal—allows data to be transmitted and received simultaneously.
DSR (data-set-ready) RTS (request-to-send) CTS (clear-to-send) CD (carrier-detect) For RS-232 specifications, DTR and RTS are for output signals and can be toggled on and off simply by double-clicking legends (such as DTR, DSR, RTS, CTS, CD) under the red/green marks. But if your are using RTS/CTS for flow control to run the test, you will see the RTS mark appear as black. This indicates that the RTS can no longer be toggled on/off since it is now controlled by driver itself.
On the performance listing area, you can see the relevant information, such as Rx Length (received packet byte length), Bytes/Sec (transmission rate) and Last Abnormal Status of each port running a test. The Status Bar is where you can glimpse the current information of the port you have selected.

Wiring RS-232 signal wiring Since the RS-232 interface is not strictly defined, many devices have their own connection methods which may ignore some signal lines or define reserved lines for other functions. It is best to refer to the user’s manual for your device for installation instructions. You may find the following helpful. In general, DTE (Data Terminal Equipment) refers to the device that is leading the communication. Examples include PC’s, terminals and some printers.
Modem connections DB-25 Male Modem (DCE) Pin 2 Signal TxD Pin 2 Signal RxD 3 RxD 3 TxD 4 RTS 4 CTS 5 CTS 5 RTS 6 DSR 6 DTR 7 GND 7 GND 20 DTR 20 DSR 8 DCD 8 DCD For DTE to DCE connections, use straight through cable (i.e., you don't have to reverse lines 2 and 3, lines 4 and 5, and lines 6 and 20 since, in general, the DCE RS-232 interfaces are reversed themselves).
RS-422 signal wiring The RS-422 interface wiring is based on one-to-one principles. The transmit lines on one side connect to the receive lines on the other side, and vice versa. With RS-422, you can transmit and receive data simultaneously (full duplex).
RS-485 signal wiring The RS-485 standard supports half-duplex communication. This means that just two wires are needed to both transmit and receive data. Handshaking signals (such as RTS, Request To Send) are normally used to control the direction of the data flow and to switch the transmission accordingly. In RS-485 mode, the PCI-1601/1602/ 1612 automatically senses the direction of the data flow and switches the transmission direction — no handshaking is necessary.
Termination resistor setup You can install termination resistors if necessary for impedance matching. The card has mounting spaces for termination resistors, but no resistors are installed at the factory. Depending on your application you may need to solder in a single resistor to handle the DATA+/ DATA- pair (and a corresponding resistor on the other end of the connection). The value of the resistor should equal the characteristic impedance of the signal wires (approximately 120 Ohms or 300 Ohms).
