PROGRAMMING SUPPORT

The HPC167064 EPROM array can be programmed using a
DATA I/O Unisite model with a pinsite module. No adaptor
board is required with the DATA I/O programmer. Program-
ming of the configuration bytes and security bits is de-
scribed in the HPC Family User’s Manual.

User’s Manual

DIAL-A-HELPER

Dial-A-Helper is a service provided by the Microcontroller
Applications group. Dial-A-Helper is an Electronic Bulletin
Board Information system and, additionally, provides the ca-
pability of remotely accessing the development system at a
customer site.

INFORMATION SYSTEM

The Dial-A-Helper system provides access to an automated
information storage and retrieval system that may be ac-
cessed over standard dial-up telephone lines 24 hours a
day. The system capabilities include a MESSAGE SECTION
(electronic mail) for communications to and from the Micro-
controller Applications Group and a FILE SECTION which
consists of several file areas where valuable application
software and utilities can be found. The minimum require-
ment for accessing Dial-A-Helper is a Hayes compatible mo-
dem.

If the user has a PC with a communications package then
files from the FILE SECTION can be downloaded to disk for
later use.

Order P/N: MDS-DIAL-A-HLP

Information System Package Contains:

Dial-A-Helper Users Manual
Public Domain Communications Software

FACTORY APPLICATIONS SUPPORT

Dial-A-Helper also provides immediate factory applications
support. If a user is having difficulty in operating a MDS,
messages can be left on our electronic bulletin board, which
we will respond to.
