OK, found the data sheet in this thread.

Looks like a regular old "HD44780" compatible. CFAH_WinTest or CrystalControl might work.

With parallel displays, it only takes 3 wires connected correctly to get the display to show that top line of characters (or lines 0 and 2 for 4 line displays) ... Vcc, Vdd, and Vo (power, ground, and contrast pins).

Check your wiring first.

If that doesn't work, check your wiring again.

99.9% of parallel display 'failures' in the hobbyist/PC user market are wiring problems.

Good wiring guides for HD44780 compatible LCD's can be found:
