NOTE: Turning OFF the Transfer Menu Select Item using the Hand-Held Terminal,
disables the Ribbon Out Sensor.
When the ribbon runs out, the sensor sends a signal to the applicator board. The applicator
board will:
• light the red light on the Warning Tower.
• Causing the yellow Ribbon LED and the red Error LED to flash.
The display will read “Ribbon Out.”
MEMORY MODULE
Although the cable and mounting hardware for the MEMORY MODULE, are standard, the
MODULES themselves are OPTIONAL. The Prodigy Plus contains two module banks (A and
B) that can hold two of four different types of modules (Font, 256K Flash, 256K RAM, and 512K
Ram). The use of these modules will depend on the software used with the PA/4000.
256K FLASH EPROM MODULE
This module contains 256K flash EPROMS, which are similar to standard EPROMS except these
have the capability to be erased electronically. Although this module may be used in either
bank A or B and contain any combination of graphic images, charters fonts, or label formats, it
must be placed in the upper bank A for programming. This module also has a write protect
switch to prevent users from over writing important data. The module can be programmed
when the write protection is off, this means the switch on the module should be moved
towards the center of the module. With the flash module you can save data while the PA/4000
is off. It will take more time to program that the ram module. The flash module is rated to be
programmed 10,000 times with no failure.
512K RAM MODULE
The 512K ram module contains ram memory which may be written to in either bank A or B.
The 512K ram is used in the upper bank (A). 256K will be used for the PA/4000's dot memory
buffer and 256K will be used for graphic images, font data, and label formats. When the 512K
ram module is used in lower bank B all 512K will be used for graphic images, font data, and
label formats.
FONT MODULES
The font modules contain programmed prom memory which may be used in either bank A or
B. The modules may not be programmed to or erased, they are programmed one time only. To
test a font module to check for corrupt data put the font module into the lower bank B. Then
turn the PA/4000 off, now hold in on the FEED button on the front panel and turn the PA/4000
on, the test label should print out the font module checksum and state if the module is good or
bad.
