3 Hardware Conﬁguration

2.3 Packing List

All models are shipped with a driver CD-ROM, which includes the documentation and the driver

software. The models VScom 200I, 200I-SI, VScom 400I and 800I UPCI also come with jumper caps

placed on the pin headers. They are placed in the “Open” position. Further with models VScom

400I and 800I UPCI a required adapter cable for DB9 male connectors is part of the package.

2.4 About this Manual

This manual describes the hardware conﬁguration of VScom Industrial Cards, as well as signal

assignments. Also general information about RS 422 and RS 485 operation is given.

The part describing the driver is generic for all VScom PCI cards, the same in all manuals. It will

describe options not available on the VScom Industrial Cards, mainly parallel ports. Just ignore

such sections.

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

This section describes in detail how to conﬁgure the serial ports of the VScom Industrial Card

to perform the required functions. On all cards is a small block of DIP switches to conﬁgure the

basic operation mode and also the electrical interface as RS 232, RS 422 or the selected mode of

RS 485.

There is another Jumper block or DIP switches, which will conﬁgure the Termination and BIAS of

the serial ports. These options must be deactivated for RS 232 operation, otherwise there will be

transmission errors. BIAS is mostly used in RS 485 modes, but may be required for the Rx± lines

in RS 422 mode also. Please read section 7 with more details on Termination and BIAS.

Finally the UPCI bus cards oﬀer a compatibility speed mode, conﬁgured by a separate jumper.

3.1 VScom 200Ei PCIex

Connector CN1 is the ﬁrst serial port, CN2 is the second port. The operation mode is conﬁgured

via the small DIP switches SW1 and SW2 according to table 7. When the serial port is conﬁgured

for any of the RS 485 modes, the transmitter has to be activated to transmit data, and disabled

when no data is sent. In Half-Duplex mode the latter function is necessary to receive data. The

RS 485 transmitter is controlled by the signal DTR.

Customers software may control the signal DTR, but this may be slow. Especially in modern

operating systems the application may not have the priority to perform this function in a timely

manner. Further, on Windows there is no option to deﬁnitely tell all data has really sent out of

the port.
