RADIO FREQUENCY INTERFERENCE

STATEMENT

This equipment generates, uses, and can radiate radio frequency energy and if
not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication. It
has been designed to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart B of Part 15 of FCC rules, which
are designed to provide reasonable protection against such interference when
the equipment is operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference, in which case the
user at there own expense will be required to take whatever measures may be
necessary to correct the interference. Changes or modifications not expressly
approved by the party responsible for compliance could void the user’s authority
to operate the equipment. This digital apparatus does not exceed the Class A

limits for radio noise emission from digital apparatus set out in the Radio
Interference Regulation of the Canadian Department of Communications.

1. Introduction

1.1 General

This manual covers both sender (Model SW-VRS232-2S) and remote (Model
SW-VRS232-2R), available either separately, or as a set.

The Hall Research 2 input switch/extender is a powerful, yet simple 2x1 VGA
and RS-232 switch. It allows one or two users to select between 2 PC’s, and
access the selected PC’s Serial RS-232 port and VGA video. A typical
installation would be connecting a touch-screen LCD to the unit and then be
able to switch the touch-screen LCD between 2 PC’s.

The local user can connect to the Sender unit. To add a remote user, an optional
2-gang wall plate would be needed. The optional wall plate connects to the local
unit via 2 Catx cables. No power supply is required for the wall plate. One Catx
cable is used to extend the Video and the other is used to extend bi-directional
RS-232. The Remote unit can be located up to 500ft. away from the Sender
Unit.

The user at the Sender station can switch between the 2 PC’s by simply pushing
a button on the unit’s front panel. LED indicators provide feedback as to which
PC input is selected.

The Remote station controls the same PC as the local (both displays show the
same image). Any RS-232 output from the PC is sent to both Stations, and RS­232 data from each station is automatically multiplexed as a first-come-first­served basis. This means that, for example, if the sender station is sending RS­232 data to the selected PC, the RS-232 data from the Remote station is
ignored until the Sender station stops transmitting data for about a second. In
this way collision of Rx data is prevented.

If control of the input selection is needed at the remote station, an optional push
button switch cord can be utilized (Model PB-SW). This push button plugs into
the receiver wall plate and can sit by the remote LCD. It has a momentary button
with built-in LED. Every time the switch is pressed the input selection is toggled
between PC 1 and PC 2. The LED on the remote push button cord blinks once
when PC 1 is selected, and twice when PC 2 is selected. The push button is
only available in a 6ft. length, but can be easily extended since it uses a
standard 3.5mm mini-stereo type of plug.
