expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model IM1/I4 generates and uses 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 and televi­sion reception. The Model IM1/I4 has been tested and complies with
the limits for a Class A computing device in accordance with the specifi­cation in Subpart J of Part 15 of FCC rules, that are designed to provide
reasonable protection from such interference in a commercial installa­tion. However, this is no guarantee that interference will not occur in a
particular installation. If the Model IM1/I4 does cause interference to
radio or television reception, which can be determined by disconnecting
the unit, the user is encouraged to try to correct the interference by one
or more of the following measures: moving the computing equipment
away from the receiver, reorienting the receiving antenna and/or plug­ging the receiving equipment into a different AC outlet (such that the
computing equipment and receiver are on different branches). In the
event the user detects intermittent or continuous product malfunction
due to nearby high power transmitting radio frequency equipment, the
user is strongly advised to use only a shielded twisted pair data cable
that is bonded to metalized external outer shield plugs at both ends.
The use of a shielded cable satisfies compliance with the
Electromagnetic Compatibility (EMC) directive.

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Patton
Technical Support.

NOTE: Packages received without an RMA number will not
be accepted.

2.3 TYPICAL APPLICATION

The Model IM1/I4 QuickConnect™ is designed to plug directly
into the rear of a Patton Electronics baseband modem (e.g. Model
1092A or 1095). The Model IM1/I4 is designed to be used as one of a
pair of units. Figure 1 (below) illustrates a typical Model IM1/I4 instal­lation.

2.2 DESCRIPTION

The Patton Model IM1/I4

QuikConnect™

is an Ethernet Bridge
with built-in four (4) port hub. The IM1/I4 interface module provides
LAN extension when used in conjunction with either the IM1/I,
IM2RC/IA, or IM1/I4 modules. The module performs transparent
Ethernet bridging and functions at the MAC level. As such, the mod­ule, and its communications infrastructure, is transparent to higher
level protocols such as TCP/IP, DECnet, NETBIOS and IPX network
protocols. Only broadcasts, multicasts, or frames destined for peered
LAN are forwarded. The Model IM1/I4 is 802.3 compliant and supports
PPP (RFC 1661) with Bridging Control Protocol (RFC 1638).

Once installed in the local Patton base unit, the Patton IM1/I4
works in a “plug and play” manner to forward LAN broadcasts, multi­casts and frames destined for the peered Ethernet LAN at the remote
end (the Patton base unit at the remote end must be equipped with an
IM/I, IM1/I4 or IM2RC/I module). Using the Patton IM1/I4, Ethernet
LANs can be linked over leased 2-wire/4-wire, DDS, PCM and campus
fiber circuits.
