1.1 RADIO AND TV INTERFERENCE

The Model 1110RC 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 1110RC 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
1110RC 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.

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 1110RC fiber optic rack card modem is the

rack mountable counterpart to Patton’s Model 1110 self-powered, fiber
optic modem. Communicating full or half duplex over dual optical
fibers, the Model 1110RC supports data rates to 19.2 Kbps and
distances to 2 miles.

Like all fiber optic modems, the Model 1110RC 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 1110RC 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 1110RC 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.

3.0 CONFIGURATION

This setting describes the location and orientation of the Model
1110RC’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 1110RC “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 1110RC “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 1110RC will have a carrier.

On Enabled
Off Disabled
