2 Introduction

1 Overview

VScom provides several models of serial port cards for the classic PCI bus. This bus will be replaced by PCIe in the future, but it is still suﬃcient for many cards with low system demand. Serial and parallel ports are examples of such devices. VScom has developed PCI serial and parallel cards since the PCI bus entered the market, and now oﬀers models ranging from one to eight serial ports. The cards are designed to control industrial hardware via asynchronous serial ports, as many software requires today. There are also models with one and two parallel ports.

The VScom UPCI cards are designed universal, they operate in the classic 5V signaling environment, as well as 3.3V PCI slots. Even the slightly newer PCI-X bus slots may be used to install and operate the card and the ports. Some models are restricted to 5V PCI slots for electrical reasons.

The supplied drivers for Windows operating system install the ports into the Windows API, so they appear as the usual Com and LPT ports software requires. A rich set of driver options is conﬁgured via the Device Manager in Windows. The driver allows to conﬁgure the serial ports for a bitrate of up to 3.6 Mbps. Of course RS 232 can not reliably transport very high bitrates, even under best conditions 1 Mbit/s is the limit. As the result of the very high maximum bitrate, there is no bitrate below 1 Mbit/s which the cards can not generate. No matter which conﬁguration the hardware requires, the VScom UPCI H-series cards deliver it.

2 Introduction

This manual describes the hardware of VScom UPCI H-series cards. UPCI is the name used in VScom products for Universal PCI products. Also the Windows driver for these cards is described in detail.

2.1 Features

• Universal PCI 33 MHz

• Serial port interface RS232

• Max 3.6Mbps

• Huge FIFO buﬀers 128 Byte

• Drivers for Windows™ operating system

• Supported by Linux

2 Introduction

2.2 Product Speciﬁcations

The VScom UPCI cards share some common properties, the most important diﬀerence is the number of serial and parallel ports. The maximum speed is 3.6 Mbit/s, but this is theoretical because the electrical interface RS 232 is not capable of such transmission rates.

2.2.3 VScom 800H UPCI

The VScom 800H UPCI card features eight serial ports, available via a universal PCI slot. All eight serial ports share one common connector DB62-female. For signal assignment see 6.1.

An adapter cable to eight times DB9-male is not provided, customers can choose from several connection options. There are Octopus-type cables to DB9 and DB25, male and female. There are also connection boxes for DB9 male, or DB25 male and female. Also converter boxes to RS 422 and RS 485 are possible.

The VScom 400H RJ45 PCI card features four serial ports, available via a classic 5V PCI slot. To place all four serial ports to the bracket only, each port is provided by an RJ45 connector. Optional available are ready made adapter cables to DB9 male, but usually the cables are conﬁgured by the customer himself.

3 Hardware Conﬁguration

2.4 About this Manual

This manual describes the hardware of VScom H-Series Cards, as well as signal assignments. There is at most one conﬁguration option for customers.

The part describing the driver is generic for all VScom PCI cards, the same in all manuals. It will describe options not available on your VScom H-Series Card. Just ignore such sections. Also Windows NT and even older versions of Windows operating system are mentioned.

The screen shots in this manual are made on an English language version of Windows XP. It is not diﬃcult to ﬁnd the appropriate part in any other language version of Windows.

The current version of the driver is 3.1.2.

3 Hardware Conﬁguration

There are not much conﬁguration options on the VScom UPCI cards, since PCI is a Plug and Play system. System parameters like address or IRQ are not deﬁned by hardware, they are assigned by software. Some models of VScom UPCI cards allow to change the clock frequency of the serial ports. This is available as “compatibility speed mode”, conﬁgured by a separate jumper.

The H-series cards are based on a 16C950 type UART, which has many advantages over the more commonly used 16C550A and compatible devices. Given a certain crystal frequency the maximum bitrate is four times as high as on a 16C550A. Since the speed conﬁguration is for software which is not aware of the added options in a 16C950, the maximum bitrate is given in 16C550A mode. This is 921,600 bps, when the top speed option is selected (which is by default).

Some models provide too many ports for placing them all on the bracket attached to the card. There are extra brackets with additional ports, connected via cable.

3.1 VScom 200H UPCI

Right below the crystal is the compatibility speed header JP1. This is used to conﬁgure the maximum bitrate of the serial ports, please see table 11.

Pins max. Bitrate Remark

2–3 921,600 Default conﬁguration 1–2 115,200 Compatibility option

Table 11: JP1 for two Speeds

The mentioned pins have to be connected by a cap to conﬁgure the operation mode. Make sure there is a cap placed in any of the two allowed positions, otherwise the ports will not operate. When the conﬁguration has been changed, the driver for Windows has to learn this. In the Advanced panel click on the “Check” button (4.2.2).
