As part of another device (the ICS 1000), this large touch-display VFD came into my lab.
IEE’s PEP 04226-01 „Vacuum Fluorescent Display“, has green chars in 6 lines per 40 chars. It seems to be out of the series „PEP Touch Screen Interface Display“ from IEE. (http://www.ieeinc.com/vacuum-fluorescent-displays)
IEE says themselves: „The UL-recognized IEE Peripheral Entry Panel (PEP) is an interactive terminal assembly integrating a 6-line by 40-character VFD with an infrared switch matrix. Interaction with the host system occurs when the operator reads displayed messages and responds by finger contact with a touch sensitive switch location on the screen. Since the switch matrix uses optical technology, no annoying grids are present to degrade the appearance of the display.
- Bright, Easy to Read 6-line by 40-character VFD
- Infrared Touch Screen Immune to Ambient Light
- Single Piece, Drip-proof, Polycarbonate Bezel
- 32 Kilobytes of Battery-backed RAM for Message Storage
- EIA-232 and EIA-422 Serial Interfaces at 1200 or 9600 Baud
- Single +5 VDC Power Supply
- Extended -40°C to +85°C Operating Temperature Range Available“
- Jumper configuration related model (04283-AX and -BX)
- Spec_1 and Spec_2 for alike VFDs (up to 4×20 chars)
Display attached to a PC and some data was entered via PCs keyboard – the display works…

Display information. MFD is week 22, 1994. Note jumpers at bottom of image
Display: power supply connector
Check of configuration inside ICS100: RS232 parameters are 9800 8N1. Note that the PEP is connected to its serial connector via a Null modem adapter.
Later research lead to the following information
Power supply connector: numbered from 1..6. Pin 6 is at the outside area of the housing.
