Run the independent MHR PWB test from an RTM terminal (diagnostics)

Use this page to run the independent MHR PWB test -- printed in source as "diagnostics" -- a stand-alone test program started from the RTM using a terminal computer, used to check the basic functions of one MHR PWB at a time (MHR-DP, MHR2-FC, or MHR-BP) and identify a defective board. This is a different tool from the console-based hwtest malfunction diagnosis program (see Related) -- hwtest start

Applies to
Activion16 (TSX-031A), Volume 2 (Console), Chapter 4 'CONSOLE', §4.6 'Navibox', §4.6.12 'Malfunction diagnosis program'. This atom is the RTM-terminal-based 'diagnostics' program (§4.6.12.4) that tests one independent MHR PWB (MHR-DP/MHR2-FC/MHR-BP) at a time. The console-based 'hwtest' program (§4.6.12.1-§4.6.12.3, pp.477-479) is a separate sibling atom (Related). No model/revision qualifier beyond Activion16/TSX-031A is stated in source.

Safety

NOTICE

Hazard: Leaving JP2 and JP3 shorted at the 1-2 position after completing a serial-number change

Consequence: the MHR PWB is left outside its normal factory-shorted (2-3) configuration

Avoidance: after entering the new serial number, return both JP2 and JP3 short pins to the 2-3 position

NOTICE

Hazard: Using the serial-number-change procedure to alter a serial number already written to the PWB's flash ROM when it shipped from the factory

Consequence: n/a in source beyond the instruction itself; (derived - not in source) would overwrite the factory-assigned serial identity printed on the PWB's own barcode label

Avoidance: do not change the serial numbers (identical to the number rewritten on the PWB's barcode label) that were rewritten when shipped from the factory

NOTICE

Hazard: Running the independent PWB test without following the printed shutdown sequence afterward

Consequence: the scan system console is left in a failed-startup state and the image display system console is left waiting for it -- the system is not usable normally

Avoidance: from the console/winterm window of the scan system console enter X: / ScanSysEnd / EndFSYS / halt, then start up and independently shut down the image display system console from the "Engineering" menu
