Boardview archive referring to conga-TS170 and TS175 modules with a TSSL tag, judging by the name, which appears to relate to congatec COM Express embedded computer modules. No revision is stated. The 3.12 MB RAR should contain a layout file viewable in a boardview program, letting a technician find components, nets and test points on these compact industrial boards. Because two module names share one file, confirm the exact module marking and revision before relying on component placement during repair.
