The Patton 1008F is a multipoint modem for short-distance transmission, housed in a compact DB-9 housing. It is designed for data transmission over twisted-pair lines in industrial or operational environments where reliable, cable-based communication without external power supply is required. The device is intended for use in point-to-point or multipoint topologies and supports up to 50 terminal connections in a multidrop network. Modem functions include data transmission as well as a control signal in each direction, making it suitable for applications requiring bidirectional control.

Applications
The Patton 1008F is used in industrial control systems, building automation, remote control systems, or other environments where serial data communication over copper lines is required. Compatibility with the 1004A model expands its application possibilities in existing infrastructures. Due to its small dimensions and integrated protection functions, the modem is also suitable for installations in limited space or environments with increased overvoltage risk.

Functions and Equipment in Detail
The modem supports asynchronous data rates up to 115.2 kbps and enables a range of up to 9 miles (14.5 km) at a data rate of 1200 bps over 19 AWG twisted pair. Transmission occurs over one or two twisted-pair lines, with the configuration adjustable to 2 or 4 lines depending on requirements. The device features five separate configuration parameters that allow individual adaptation to specific applications. These include selection of RTS/CTS delay, operation with or without Echo", two different impedance settings, and choice between "Carrier ON" or "RTS Controlled.

Technology Explained Simply
The modem operates without external power supply — neither AC mains voltage nor batteries are required. Power is supplied through the data line itself, simplifying installation and eliminating dependence on additional power sources. The integrated overvoltage protection function is based on silicon avalanche diodes and protects the device from transient voltage spikes caused by lightning or electrical disturbances. This protection function is standard and increases reliability in critical applications.

Compatibility and Accessories
The modem is compatible with the Patton 1004A model, facilitating integration into existing systems. It is designed for operation in point-to-point or multipoint networks and supports data transmission as well as a control signal in both directions. Configuration options allow flexible adaptation to different network topologies and requirements.

Mounting and Installation
Installation is performed via a DB-9 connector, which connects to existing serial devices or control systems. Due to its compact design and integrated protection functions, the modem is easy to install and requires no additional components. Configuration is done via the five available parameters, which can be adjusted according to the application scenario.

Advantages in Operation
The Patton 1008F provides reliable data transmission without external power supply, simplifying installation and maintenance. The integrated overvoltage protection function increases the device's lifespan and safety. Support for up to 50 terminal connections in a multidrop network makes it a scalable solution for industrial applications. Compatibility with the 1004A model and flexible configuration enable easy integration into existing systems.

FCC Approval and Manufacturing
The device complies with FCC Part 15, Class A, which regulates emission characteristics for industrial and commercial environments. The modem is manufactured in the USA in Gaithersburg, Maryland, with design and production carried out by Patton technicians. Manufacturing follows American quality standards, ensuring high reliability of the devices.
