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

1.1 RADIO AND TV INTERFERENCE

The Model 3010 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 3010 is 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 3010 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 [phone].

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
Model 3010. Technical Service hours: 8AM to 5PM EST, Monday

2.2 DESCRIPTION

The Model 3010 Three Port Modem Sharing Device allows three

POS terminals, ATMs or similar RS-232 devices to share a single
RS-232 modem or multiplexer. The Model 3010 requires no AC power
or batteries, operates asynchronously or synchronously and is small
enough to plug directly into the DB-25 serial port on a modem or
multiplexer.

The Model 3010 operates by allowing the modem to pass data and
control signals to all three DTE devices in parallel. Concurrently, the
Model 3010 monitors each DTE device to see if it has data to send to
the modem. When a terminal has data to send, it raises RTS and all its
data and control signals are routed to the modem. As soon as that
terminal is finished sending data, the Model 3010 resumes monitoring.
If two or three terminals raise RTS simultaneously, the Model 3010
prioritizes the inputs: DTE channel one has priority over channel two,
and channel two has priority over channel three.

The Model 3010 supports synchronous or asynchronous data rates
from 300 to 38,400 bps. When operating synchronously, the Model
3010 derives the clock externally from the connected modem. No pre­configuration is required to use the Model 3010—it's strictly "plug and
play". The Model 3010 is equipped with one male DB-25 for the
modem connection and three female DB-25s for the DTE connections.
