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).

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.
