product should it fail within one year from the first date of shipment. This
warranty is limited to defects in workmanship or materials, and does not
cover customer damage, abuse or unauthorized modification. If this
product fails or does not perform as warranted, your sole recourse shall
be repair or replacement as described above. Under no condition shall
Patton Electronics be liable for any damages incurred by the use of
this product. These damages include, but are not limited to, the
following: lost profits, lost savings and incidental or consequential
damages arising from the use of or inability to use this product. Patton
Electronics specifically disclaims all other warranties, expressed or
implied, and the installation or use of this product shall be deemed an
acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model 505M-CHC does not generate or use radio frequency
energy. However, when used together with other devices that generate
or use radio frequencies, improper installation may interfere with radio
and television reception. They have 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 these products do cause interference
to radio or television reception, which can be determined by turning off
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.

2.1 PRODUCT DESCRIPTION

The Patton Model 505M-CHC Surge Protected DB-25 to RJ-45
Modular Adapter allows you to simplify cabling connections and

protect your RS-232 DB-25 equipment at the same time. Using 39 Volt
clamping Silicon Avalanche Diodes (SADs), the 505M-CHC provides up
to 1500 Watts of surge protection per pin. The 505 protects pins 2
(TD), 3 (RD) and 7 (SG) using a modular RJ-45 jack. Surges are
shunted safely to chassis ground through the D-shell connector.

WARNING!!: These products will not provide complete protection

should your equipment be subject to a direct lightning hit.

2.2 SURGE PROTECTION BENEFITS

The method of surge protection used in the Model 505M-CHC
adds four benefits to your system:

1)

High Surge Capacity

. The Model 505M-CHC dissipates up to

1500 Watts per wire in 1.0 millisecond.

2)

Quick Response.

The Model 505M-CHC has a fast response
time (1 pS at the component level; 0.5 μS installed). Transient
surges are clamped at 39V.

3)

Low Impedance.

The Model 505M-CHC adds minimal load to

your system--about the same as a gender changer.

4)

Shorting Failure.

The Model 505M-CHC fails into a short
circuit if your system experiences a severe transient or power fault
above the rated voltage of the protector. Data and surge energy is
shunted directly to chassis ground through the shorted SAD, and
will not disrupt the system.

3.0 MODEL 505M-CHC INSTALLATION

The Patton Model 505M-CHC is simple to install and requires no

user configuration. Follow these installation steps:

1) Be sure the metal D-sub connector on the device you are
protecting is connected to frame ground. If not, see step 4,
below.

2) Plug the DB-25 connector of the Model 505M-CHC

directly

into the DB-25 serial port of the device you are protecting.
Avoid using additional cables between the device and the
Model 505M-CHC because a serial cable reduces the
effectiveness of the protection you would otherwise receive.

3) Plug your modular cable into the jack on the Model 505M­CHC. The cable must be terminated with an RJ-45 plug.

4) To provide an alternate ground connection, use the short strap
supplied with the unit. Connect one loop to the device chassis
(or other chassis ground) and the other loop to the Model
505M-CHC as shown below.
