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.

Model VSA-31-IP

1. Introduction

1.1 General

The model VSA-31-IP is a member of Hall Research powerful RS232 product line. The
unit allows the user a flexible interface to perform the following functions:

• Monitor the RS232 communication between 2 serial devices from a remote
LAN connection

• Independently send and receive RS232 signals to separate serial devices from
a remote LAN connection at any speed

• Timeout feature - Default back to a standard communication path after 3
minutes to ensure that the 2 serial devices are always connected

• Detect connection to RS232-A port from a remote LAN connection without
disturbing the communication between RS232-A and RS232-B

When the VSA-31-IP is used to add IP capability to a classroom equipped with Hall
Research Switch-Cat® system, it is inserted in the RS-232 path between the VSA-31
Receiver and the Projector. It draws power from the VSA-31 Receiver and includes the
cable for connection to the VSA-31 Receiver.

2. Installation

2.1 Connecting the Unit

Refer to Figure 1 and 2 below for connector identification.

Connect the “RS232-A” and the “RS232-B” ports to the serial devices using
appropriate cables (for example, since the VSA-31 Receiver has a DB9 Male
connector, a Female/Female RS-232 NULL Modem cable should be used).

Connect the “LAN” port to a network Ethernet connection using standard CATx
cables (not supplied with unit)

Connect the “PWR” jack to the power supply (optional) or connect the unit to a Hall
Research compatible device capable of powering the unit via the RS232-B port
using the supplied RS232 Null Modem cable.

2.2 Connector Pin Out

RS-232-A Connector: This 9-pin D-sub connector is normally used to connect to the

“Controlled” device, such as a Projector (though any serial device is acceptable).

7 RTS Pulled High

RS-232-B Connector: This 9-pin D-sub connector is normally used to connect to the
“Controller” device, such as a VSA-31 Receiver (though any serial device is acceptable).
This connector can also be used to power the VSA-31-IP unit. The power source must
be capable of 12-15 vDC @ 250 mADC minimum.

PWR connector: This is a standard 2.5mm plug connection. The unit’s power supply is
12-15 volts DC with a minimum rating of 250 mADC. Upon application of power from
the 2.5mm PWR connector or by the RS-232-B Pin 6, the 10/100 and Status LED’s will
either blink or become illuminated solid. Refer to Section 2.2 for a description of the LED
functions.

LAN connector: This is a standard RJ-45 Ethernet connection capable of be connected
to any 10/100 BaseT network.
