Parallel Printer Adapter
The Sine Systems model PA-2 Printer Adapter gives the RFC-1/B Remote Facilities Controller the ability to print to a standard parallel printer. 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 and provide access to the 25 pin D connector.
The printer interface is a 25-pin D type connector. The system has front panels LEDs that indicate power, operating mode and data transmission.
Automatic data logging can be accomplished fairly quickly by programming the RFC-1/B to send a set of readings to the printer at scheduled intervals.
The PA-2 printer interface is electrically isolated to minimize the potential for surge damage to the rest of the system. It communicates with the RFC-1 over optically isolated data lines and is powered by an isolated supply.
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.
