1.1 RADIO AND TV INTERFERENCE

The Model 1070RC 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 1070RC 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
1070RC does cause interference to radio or television reception, which
can be determined by turning the power off or removing the card, 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). 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 take the following steps: use only data cables with
an external outer shield bonded to a metal or metalized connector; and,
configure the rear card as shown in section 3.3 of this manual.

2.2 DESCRIPTION

The Model 1070RC Synchronous Short Range Modem Rack

Card operates full duplex, over two unconditioned twisted pair.

Supporting data rates to 19.2 Kbps, the Model 1070RC has a maximum
range of 10 miles (@ 1200 bps over 19 AWG wire). The Model
1070RC passes one control signal in each direction, and features both
optical isolation and Silicon Avalanche Diode surge protection on the
data lines side. Clocking can be sourced internally or externally.

The Model 1070RC is designed to mount in Patton's 2U high 19"
rack chassis. This 16 card chassis has a switchable 120/240 volt
power supply and mounts cards in a mid-plane architecture: The front
"brains" half-card can be plugged into different rear "interface" cards.
This means that the 1070RC card can have several interface options,
and can be switched with other Patton short haul cards.

The Model 1070RC has two built-in diagnostic tools: local and
remote loopback test. Additionally, bi-level LEDs on the 1070RC's
front panel allow you to visually monitor communication.

3.0 CONFIGURATION

This section describes the location and orientation of the Model
1070RC's configuration switches, provides detailed instructions on
setting each switch, and describes strap settings for each of the rear
connection cards.

The Model 1070RC uses a set of eight DIP switches that allow
configuration to a wide range of synchronous applications. These DIP
switches are accessible when the card is slid out of the rack chassis.
Once configured, the Model 1070RC is designed to operate
transparently, without need for frequent re-configuration.

Transmit Clock

Switch 5 is used to specify the clocking method. The Model
1070RC can provide an internal clock (Pin 15),or receive an external
clock (from Pin 24).

Switch 5

On = Internal
Off = External

RTS/CTS Delay

Switches 6 and 7 are used together to specify RTS/CTS delay.
After request to send (RTS) is raised by the host terminal, the 1070RC
raises CTS after a slight delay in order to give the remote terminal time
to receive an incoming signal. Depending on the type of environment,
either a 0 mS, 8 mS or 53 mS delay can be selected.

Switch 6

Switch 7
On On = 0 mS
On Off = 8 mS
Off Off = 53 mS

Carrier Enable

Switch 8 is used to specify how the carrier signal is raised. In most

point-to-point , full duplex applications, the carrier signal can remain
constantly "high". Important Note: In a multi-point environment, set
the host to "Constant Carrier" and each slave to "Controlled by RTS".

Switch 8

On = Controlled by RTS
Off = Constant Carrier

4.0 INSTALLATION

This section describes the functions of the Model 1000R16 rack
chassis, tells how to install front and rear Model 1070RC cards into the
chassis, and provides diagrams for wiring up the interface connections
correctly.

4.1 THE MODEL 1000R16 RACK CHASSIS

The 1000R16 Rack Chassis (shown in figure 10, below) has
sixteen short range modem card slots, plus its own power supply.
Measuring only 3.5" high, the 1000R16 is designed to occupy only 2U
in a 19" rack. Sturdy front handles allow the 1000R16 to be extracted
and transported conveniently.

Figure 10. Model 1000R16 Rack Chassis with Power Supply

4.1.1 THE RACK POWER SUPPLY

The power supply included in the Model 1000R16 rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by spring loaded thumb screws and the
rear card by conventional metal screws.

WARNING! There are no user-serviceable parts in the

power supply section of the Model 1070RC Series.
Voltage setting changes and fuse replacement should only
be performed by qualified service personnel. Contact
Patton Electronics Technical support at [phone] for
more information.

4.2 INSTALLING THE MODEL 1070RC INTO THE CHASSIS

The Model 1070RC is comprised of a front "brains" half card and a

rear "connections" card. The two cards meet inside the rack chassis
and plug into each other by way of mating 50 pin card edge connectors.
Use the following steps as a guideline for installing each Model 1070RC
into the Model 1000R16 rack chassis:

1. Slide the rear "connections" card into the back of the

chassis along the metal rails provided.

2. Secure the rear card using the metal screws provided.

3. Slide the "brains" card into the front of the chassis. It should

meet the rear card when it's almost all the way into the

chassis.

4. Push the front card

the rear card. It should "click" into place.

5. Secure the front card using the spring loaded thumb screws.

5.3 TEST MODES

The Model 1070RC offers two diagnostic modes: local analog loop

and remote analog loop. These test modes are activated

simultaneously

by depressing the "Test" button on the front panel of the

Model 1070RC.

Local Analog Loop

The Local Analog Loop test mode causes any data sent to the

local 1070RC by the local RS-232 device to be echoed

back

to that RS­232 device. For example, characters typed on the keyboard of a
terminal will appear on the terminal screen. If characters are not
echoed back, check the connection between the local RS-232 device
and the local 1070RC. All 1070RC's in the system should be tested in
this manner

Remote Analog Loop

The Remote Analog Loop test mode causes any characters sent

from the

remote

remote

1070RC to the local 1070RC to be returned back to the

device (see Figure 13). Note: Only the

local

1070RC should

be in "test" mode. The remote 1070RC should be in "normal"

operating mode or this test will not work. If no characters are echoed
back, check the wiring between the two 1070RCs. Be sure to wire the
units according to the instructions in Section 4.0 Installation.

To gain optimum performance from the 1070RC, please keep the
following guidelines in mind:

•

Always

use twisted pair wire--this is not an option.

• Use twisted pair wire with a capacitance of 20pf/ft or less.

• Avoid twisted pair wire thinner than 26 AWG (i.e. avoid higher

AWG numbers than 26)

• Use of twisted pair with a resistance greater than the above

specifications may cause a reduction in maximum distance

obtainable. Functionality should not be affected.

• Environmental factors too numerous to mention can affect the
