1.1 RADIO AND TV INTERFERENCE

The Model 1094 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 1094 has been tested and found to com­ply with the limits for a Class A computing device in accordance with
the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interfer­ence will not occur in a particular installation. If the Model 1094 does
cause interference to radio or television reception, which can be deter­mined by removing power from 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, re-orienting
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).

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 Technical
Support.

2.2 DESCRIPTION
The Patton Model 1094 Synchronous Short Range Modem

is designed for point-to-point, high speed communication over 4-wires
(two twisted pair). Supporting switch-selectable data rates of 384 and
768 kbps, the Model 1094 is perfect for connecting two bridge/routers,
or for similar campus applications at distances up to 4.9 miles (7.9 km).
The Model 1094 incorporates built-in V.54 loopback tests, a V.52 BERT
pattern generator and seven front panel LED indicators. Data integr ity
is enhanced by automatic equalization and gain control. The Model
1094 also incorporates transformer isolation and surge protection to
guard data and connected equipment against the hazards of ground
loops and transient surges. Clocking options include internal, external
and receive recover clock.

The Model 1094 features replaceable DCE-DTE QuickConnect™
interface modules.Several different modules are available (call Patton
Sales for details). Line connection is made by RJ-45 jack. Internal AC
power supply options include 120 or 230VAC (switchable), 85-256VAC
(universal) or 48VDC.

3.0 CONFIGURATION

The Model 1094 is equipped with one set of eight DIP switches,
and one set of four DIP switches (all externally accessible). These DIP
switches allow configuration of clock source, carrier control, loopback
tests and data rate.This section describes switch locations and
explains all possible configurations.

3.1 EXTERNAL DIP SWITCH SETTINGS

The Model 1094’s DIP switches are located on the underside of
the unit (see Figure 1, below). Figure 2 shows the orientation of the
switch set. All possible settings for the Model 1094’s DIP switches are
presented in the summary table and descriptions on the following
pages.

3.1.1 Switch Set S1

The configuration switches on S1 set clock source, RTS/CTS
delay, carrier control, loopback tests. The default settings are summa­rized in the table above.

Switches S1-1 and S1-2: Clock Source

Switches S1-1 and S1-2 are set in combination to determine the
source of timing for the Model 1094.

S1-1

S1-2 Setting
On On Internal
On Off Receive recover
Off On External transmit clock
Off Off Not a valid setting

Switch S1-3: RTS/CTS Delay

Switch S1-3 is used in combination to determine the amount of
delay between the time RTS is activated and the 1094 activates the
CTS.

S1-3

Function
On Short delay (1-4 ms)
Off Long delay (8-20 ms)

Switch S1-4: LDL Control

Switch S1-4 determines whether the frontt panel switch can acti-

vate a Local Digital Loopback (LDL) diagnostic test.

S1-4 Function

On LDL Control Enabled
Off LDL Control Disabled

Switch S1-5: Carrier Control

The setting for switch S1-5 determines whether the carrier is “con­stantly on” or “controlled by RTS”. This setting allows for operation in
switched carrier or hardware handshaking applications.

S1-5

Setting
On Controlled by RTS
Off Constantly ON

Switch S1-6: DTE Control of RDL

The setting for switch S1-6 determines whether DTE control of
remote-digital loopback test is enabled or disabled. If DTE control is
disabled, the RDL test can only be initiated by the front panel switch.

S1-6

Setting
On DTE control enabled
Off DTE control disabled

Switch S1-7: DTE Control of LAL

The setting for switch S1-7 determines whether DTE control of
local analog loopback test is enabled or disabled. If DTE control is dis­abled, the LAL test can only be initiated by the front panel switch.

S1-7

Setting
On DTE control enabled
Off DTE control disabled

NOTE: When an X.21 QuickConnect™ module is installed in

one or both base units, one base unit

must

be configured for
receive recover clock source. The par ticular application will
dictate which unit must be configured for receive recover clock
source.
