1.1 RADIO AND TV INTERFERENCE

The Model 2026P 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. They have been tested and found to comply with
the limits for Class Acomputing devices 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 they do cause interference to radio
or television reception, which can be determined by disconnecting the
RS-232 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). ACertificate of Compliance is available by contacting Technical

the case, insert a small screwdriver into one of the slots on the side of
the plastic case. Then twist from side to side until the case opens.

The configuration switches allow you to select data rates, parity,
word length and flow control selection. The following section describes
all switch locations, positions and functions.

To configure your unit, use a small screwdriver and gently push
each switch to its proper setting. The ON and OFF positions are
shown in Figure 2. Default settings for the DIP switches are shown in
