1.1 RADIO AND TV INTERFERENCE
The Model 1004 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 tele-
vision reception. The Model 1004 has been tested and found to com-
ply 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 interfer-
ence will not occur in a particular installation. If the Model 1004 does
cause interference to radio or television reception, which can be deter-
mined by disconnecting the RS-232 interface, the user is encouraged
to try to correct the interference by one or more of the following meas-
ures: moving the computing equipment away from the receiver, re-ori-
enting 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.

RMA number will not be accepted.
Patton Electronics' technical staff is also available to answer any

2.2 DESCRIPTION
The Model 1004 High Speed, Multipoint Short Range Modem
provides exceptional versatility in a compact package. Requiring no
AC power or batteries for operation, the Model 1004 supports asyn-
chronous RS-232 data rates to 115.2 Kbps over one or two uncondi-
tioned twisted pair. Distances up to 9.4 miles are attainable at lower
data rates (19.2 Kbps, 19 AWG twisted pair).
The Model 1004 can handle up to 50 terminal drops in a multipoint
polling environment. For RS-485 and serial printer applications requir-
ing hardware handshaking, the Model 1004 passes one control signal
in each direction. The Model 1004 may be configured for high or low
impedance operation, and carrier may be set to “constantly on” or
“controlled by RTS”.
Options for twisted pair connection include terminal blocks with
strain relief, RJ-11, RJ-45 and dual modular connectors for daisy chain-
ing. The surge protected Model 1004S incorporates Silicon Avalanche
Diodes which provide 600 watts per wire of protection against harmful
data line transient surges.
