1.4 MEMBRANE SWITCH PANEL

Four membrane switches are provided on the left side of the MSP/MPP printers for various

operator controls. The switches are labeled <SLCT>, <FEED>, <SET> and <ADVN>. The

functions performed by these switches are summarized below.

The <SLCT> or <ON> switch is used to turn printer power on.

The green <ON-Line> LED is illuminated, if printer is selected.

<FEED>

The <FEED> switch is used to advance the paper by one line.

The <SET> or <OFF> switch is used to turn the printer OFF. The <Error> LED starts flashing

when set switch is pressed.

The <ADVN> or < > switch is used to advance paper by one line.

1.5 DATA CONNECTOR

The Data Connector of the MSP/MPP printer is located at the front of the printer. Figure 1.0

shows the front panel of the MSP/MPP Printer series. The serial and parallel input/output

signals of the MSP/MPP compact printers are terminated on a 25 pin, DB25S female connector.

Pin assignments and technical specifications for each type of interface are listed in Chapter 3.

1.6 POWER INPUT

The MSP/MPP compact printers receive DC power via Extech rechargeable battery pack or

through a two (2) conductor Power Input Connector located on the right side of the printer.

NOTE: The printer must be operated with the battery installed when the

Power Adapter is used. Failure to do so will invalidate the warranty.

1.6.1 AC POWER ADAPTER

A wall mount UL listed power adapter is provided to operate the printer. The AC Power

Adapter plugs directly into an AC power outlet while it's mating DC plug, on a 6 ft

extension, connects to the printer. The center pin is the positive DC input, while the

body of the connector is logic common or DC negative input.

The AC Power Adapter is internally fused and it's output is rated at 9 VDC/1.0A for

MSP II printer series and 9VDC/2.0A for MSP III. The Power adapter AC input is

available for either 110 VAC or 220 VAC.
