RAA-E UNIT UPGRADE

ELECTRA MARK11

ETI NUMBER: MK-016 DATE: APRIL, 1990

1.DESCRIPTION

:

This Engineering Technical information (ETI) bulletin provides the steps necessary to upgrade an existing RAA-E Unit to revision 2A which involves changing one IC. This upgrade is required in order to use the RAA-E Unit with the RAA Unit Disk (COMLINK: V2.0 or higher) and the System Data Up/Down Load (DATASAVE) (Stock No. 700539 for 5.25’ diskette or No. 700540 for 3.5’ diskette) software. RAA-E Units revision 3 or higher do not require this upgrade.

2.PARTS REQUIRED

2.1The RAA-E Unit Upgrade Kit (Stock No700537) consists of:.

2.1.1One revision A label.

2.1.2One revision 2A label.

2.1.3One V3.1 EPROM IC.

2.1.4RAA-E Unit Disk (COMLINK) V2.0.

2.2Anti-static wrist band and grounding strap (3M Model 2213 or similar, locally provided).

2.3Anti-static mat (3M Model 8501 or similar, locally provided).

2.4IC Chip insertion/extraction tool capable of handling a 28 pin IC (locally provided).

CAUTION: Microprocessors and some other chips used on the RAA-E Unit are static sensitive devices. Proper care in handling is necessary to assure that neither the microprocessor nor the printed circuit board (PCB) is damaged. This procedure minimizes the possibility of damage due to static electricity discharge.

3.SET UP PROCEDURE

3.1Attach the anti-static mat to earth ground.

3.2Put on the anti-static wrist band and attach the band to the anti-static mat.

3.3Unpack the new EPROM IC and labels provided.
