2.2 DESCRIPTION
Figure 1. Model 1110ARC front card jumper locations
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.
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.
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.
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.

3.2 REAR CARD SETTINGS
DTE Shield (Pin 1) & FRGND (JB1)
The Model 1110ARC is compatible with two dual-fiber interface
cards, one with dual ST connectors and one with dual SMA connectors.
Both cards use an HD-26 female for the RS-232 interface. The
jumpers on both interface cards function identically. Figure 2 (below)
shows the location of the jumpers.
In the connected (closed) position, this strap links DB-25 pin 1 and
frame ground. In the open (disconnected) position, pin 1 is “lifted” from
frame ground.

4.0 INSTALLATION
Switching the Power Supply On and Off
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.
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.
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.
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.
Figure 4. Model 1000R16 rack chassis with power supply
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.
4.1.1 THE RACK POWER SUPPLY
4. Push the front card gently into the card-edge receptacle of the
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.
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.
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
[email protected] for more information.
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.
5.0 OPERATION
4.3.1 RS-232 CONNECTION
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.
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.
5.1 LED STATUS MONITORS
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 (301) 975-1000 for price and
delivery information.
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.
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.
•
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.
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.
5.2 POWER-UP
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:

• TD & RD = flashing red and green
