SSI Memory Module Tester
Park Signalling's Memory Module Tester is a standalone unit for use with SSI MkII memory modules.
Memory Module being tested
The tester provides the following functions:
- Go/Nogo test of the memory module
- EPROM checksum identification
- RAM test
- Address mapping test
The Memory Module Tester consists of test control software running on a PC, a memory module test interface and interconnection leads.
MkII MPMs and PPMs use various configurations of memory modules. Each module contains EPROMs and RAM; the EPROMs contain the main program software and railway scheme specific data. Some memory modules also use paged memory to access data in the EPROM.
The tester is capable of diagnosing the status of the Memory Module and provides a clear indication of any failure found. A record of the test and the results is automatically generated and may be saved for reference purposes.
