Patton Electronics

be liable for any damages incurred

Patton Electronics

specifically disclaims all other warranties,

expressed or implied, and the installation or use of this product shall be

1.1  RADIO AND TV INTERFERENCE

The Model 1008 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 1008 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 1008
does cause interference to radio or television reception, which can be
determined by disconnecting the EIA/TIA-574 interface, 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.

straight through

cable of the shortest possible length—we

recommend 6 ft or less.  The DB-9 connector on the Model 1008 is
wired according to the EIA/TIA-574 Standard, as shown below:

Note:

The Model 1008 is configured as a DCE (Data

Communications Equipment), and is therefore designed to connect to a
DTE (Data Termination Equipment).  If you need to connect the Model
1008 to another DCE device, please call Patton Technical Support at
(301) 975-1007 for details on constructing the proper crossover cable.

4.4   OPERATING THE MODEL 1008 

Once the Model 1008 is properly installed, it should operate

transparently—as if it were a standard cable connection.  Operating
power is derived from the RS-232 data and control signals; there is no
“ON/OFF” switch.  All data signals from the RS-232 and RS-485
interfaces are passed straight through.  Additionally, one hardware flow
control signal is passed 

in each direction
