Not happy :>((
It's easy to be a little confused...
The NASA Navtex Pro is a stand alone unit which stores and displays Navtex messages. I think it is only single channel. (518)
The NASA Navtex Pro Plus is a stand alone unit which stores and displays Navtex messages. It is dual channel.
The NASA Navtex engine is just that; a navtex receiver for feeding navtex data to a device. If the device isn't ready to receive data, tough.
The NASA MARINE PC Navtex Pro is a navtex engine with internal storage but it needs to hand shake with a PC to dump the messages to the PC program. It is dual channel. I may be wrong but wouldn't imagine your plotter would be able to handshake with it. It is supplied with a PC program for doing this.
