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 2017P 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 2017P 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
2017P does 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 SERVICE
All warranty and non-warranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container. This number may be obtained from Patton Electronics
Technical Service at (301) 975-1007.
Packages received without an
RMA number will not be accepted.
Patton Electronics' technical staff is also available to answer any
questions that might arise concerning the installation or use of your
converter. Hours: 8AM to 5PM EST, Monday through Friday.

2.2 DESCRIPTION
The Model 2017P RS-232 to 20mA current loop converter lets
an asynchronous RS-232 device communicate with a 20mA current
loop device (the Model 2017P60 works with 60mA current loop
devices). The Model 2017P requires no AC power or batteries to
operate and supports data rates to 115.2 Kbps.
Operating full duplex, the Model 2017P supports communication
distances up to 4 miles over two unconditioned 24 AWG twisted pair.
To guard against data loss due to ground loops, the Model 2017P is
equipped with 2500V RMS optical isolators on the line side.
The Model 2017P connects directly to the RS-232 interface using a
male or female DB-25 connector. Two-pair cable running to the 20mA
current loop device attaches to the Model 2017P by RJ-11 jack, RJ-45
jack or terminal blocks with built-in strain relief. An external DCE/DTE
switch on the Model 2017P eliminates the need for a cross-over cable
on the RS-232 interface. Like all Patton products, the Model 2017P is
manufactured in the USA.
