Model RS-232

RS-232 Serial Data Adapter

Features

Serial Data Adapter

The RS-232 Serial Data Adapter allows remote data access to the RFC-1/B via using a serial data connection. It consists of a small PC board that connects to the the RFC-1 with a jumper connector. An extended case and new rack panel are included to enclose the assembly.

The data interface is a 9-pin D type connector. The system has front panels LEDs that indicate power, operating mode and data transmission.

Remote data logging can be accomplished fairly quickly by programming the RFC-1/B to place a call and send a set of readings automatically. The data can be collected by just about any computer capable of receiving and storing a simple ASCII data stream.

More involved tasks can be performed using a communications program that features scripting like Procomm Plus or Telix. The RFC-1/B responds to the same commands over the data link that are used in voice mode.

Using the RFC-1/B in data mode does not exclude use in voice mode over a telephone.

System Requirements

RFC-1/B software version 4.00 or later is required to operate the RS-232 Adapter. Most RFC-1 systems are running version 5.x so this is typically not an issue.

Use the command "78" while online with the RFC-1 to read the software version.
