1.1 RADIO AND TV INTERFERENCE

The Model 1110ARC 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 1110ARC 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
1110ARC 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 3.2 of this manual.

2.2 DESCRIPTION

The Patton Model 1110ARC fiber optic rack card modem is the

rack mountable counterpart to Patton’s Model 1110A self-powered, fiber
optic modem. Communicating full or half duplex over dual optical
fibers, the Model 1110ARC supports data rates to 19.2 Kbps and
distances to 4 miles.

Like all fiber optic modems, the Model 1110ARC is inherently
immune to RFI/EMI noise, ground loops and transient surges. The
carrier may be switch selected as either “Continuously On” or
“Controlled by RTS”. Four pairs of bi-level LED indicators monitor TD,
RD, RTS and CD. A single LED monitors power.

The Model 1110ARC 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.
The Model 1110ARC is available with a choice of two interface cards:
one with SMA connectors, and one with ST connectors. Both cards are
equipped with an HD-26 female connector for the RS-232 interface.

This setting describes the location and orientation of the Model
1110ARC’s configuration jumpers. There are two sets of jumpers to
set: those on the front “brains” card and those on the rear “interface”
card.

3.1 FRONT CARD SETTINGS

The jumpers on the Model 1110ARC “brains” card set RTS/CTS
delay and carrier control. Figure 1 (below) shows their location on the
PC board.

JP1 and JP2: RTS/CTS Delay

The combined settings for jumpers JP1 and JP2 determine the
amount of delay between the time the Model 1110ARC “sees” RTS and
when it sends CTS.

JP1 JP2 Setting

Off Off No delay
On Off No delay
On On 9.0 mS
Off On 79.5 mS

JP3: Carrier Detect

The settings for jumper JP3 determines whether carrier detect is
enabled or disabled. Carrier detect feature responds to RTS; if RTS is
on, the Model 1110ARC will have a carrier.

JP3 Setting

On Enabled
Off Disabled

4.0 INSTALLATION

WARNING! There are no user-serviceable parts in the power

supply section of the Model 1110ARC. Voltage setting changes
and fuse replacement should only be performed by qualified
service personnel. Contact Patton Electronics Technical
support at [phone], http://www.patton.com, or
[e-mail] for more information.

This section describes the functions of the Model 1000R16 rack
chassis, tells how to install front and rear Model 1110ARC cards into the
chassis, and provides instructions for connecting the interface cables.

4.1 THE MODEL 1000R16 RACK CHASSIS

The 1000R16 Rack Chassis (Figure 4, 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 4. 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 thumb screws and the rear card by
conventional metal screws.

Switching the Power Supply On and Off

The power supply on/off switch is located on the front panel.
When plugged in and switched on, a red front panel LED will glow.
Since the Model 1000R16 is a “hot swappable” rack, it is not necessary
for any cards to be installed before switching on the power supply. The
power supply may be switched off at any time without harming the
installed cards.

NOTE: Please refer to the Model 1000RP Series User Manual AC

and DC Rack Mount Power Supplies for fuse and power card

replacement information.

4.2 INSTALLING THE MODEL 1110ARC INTO THE CHASSIS

The Model 1110ARC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other
via mating 50 pin card edge connectors. Use the following steps as a
guideline for installing each Model 1110ARC into the Model 1000R16
rack chassis:

1. Slide the rear card into the back of the chassis along the metal

rails.

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

3. Slide the front 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 gently into the card-edge receptacle of the

rear card. It should “click” into place.

5. Secure the front card using the thumb screws.
Note: Since the Model 1000R16 chassis allows “hot swapping” of

cards, it is not necessary to power down the rack when you install or
remove a Model 1110ARC.

4.3 WIRING UP THE MODEL 1110ARC

Both of the rear interface cards compatible with the Model
1110ARC have one RS-232 port and one dual-connector fiber port.
Depending upon the card you have, the fiber port will be either an ST
or SMA connector. The RS-232 port is always a female HD-26
connector.

4.3.1 RS-232 CONNECTION

Figure 5. Close up of ST and SMA connections

The RS-232 port on the rear card of the Model 1110ARC is wired
as a DCE, and uses a female HD-26 connector. The HD-26 is an
alternate connector according to the EIA RS-232E specification, and
the pin-out is the same as a standard DB-25. Pin 26 is not used.

You will need an interface cable to connect the Model 1110ARC to
your RS-232 device. Assuming your RS-232 device is a DTE (PC,
host, terminal, workstation, etc.), the cable should be wired straight
through . You may either provide your own cable, or you may purchase
an HD-26 to DB-25 cable from Patton Electronics Company. Please
call the Patton Sales Department at [phone] for price and
delivery information.

Notice! Any terminal cable connected to the Model 1110ARC

must be shielded cable, and the outer shield must be 360
degree bonded–at both ends–to a metal or metalized backshell.

4.3.2 FIBER CONNECTIONS

The Model 1110ARC is designed to work with the self-powered
Model 1110A, or with another Model 1110ARC. In either case, you will
need one unit at each end of a dual fiber cable. This cable connects to
the Model 1110ARC using either ST or SMA connectors. Figure 5
(following page) shows a close-up of each of these connector types.

5.0 OPERATION

Once you have configured each Model 1110ARC and connected the
cables, you are ready to operate the units. This section describes the
LED status monitors and power-up procedure.

5.1 LED STATUS MONITORS

The Model 1110ARC features nine front panel status LEDs that
indicate the condition of the modem and communication link:

• The green “PWR” LED glows when power is applied to the modem

card through its mid-plane chassis connection.

• The green “TD” and “RD” indicators blink to show positive state

data activity. The Red “TD” and “RD” indicators blink to show
negative state data activity. Solid red indicates an idle state.

• The green “RTS” and “CD” indicators glow solid to show the

control signal is on. The red “RTS” and “CD” indicators glow solid
to show the control signal is off. When the 1110ARC is connected
to a DTE, RTS will glow green for an incoming signal on RS-232
pin 4. CD will glow green for an incoming signal from the line, and
an outgoing signal on RS-232 pin 8.

5.2 POWER-UP

alignment pin
faces down

There is no power switch on the Model 1110ARC: Power is
automatically applied to the 1110ARC when its card-edge connector
makes contact with the chassis’ mid-plane socket, or when the chassis’
power supply is turned on. Note: The 1110ARC is a “hot swappable”

card—it will not be damaged by plugging it in or removing it while the
rack is powered up.

When the local and remote units are both powered up, and are
passing data normally, the following LED conditions will exist:

• PWR = green

• TD & RD = flashing red and green

• RTS & DCD = green
