The CONTROL-L  (LANC)  connector on the VCR will be either
a 5pin mini-DIN connector,  or a three conductor sub-mini 
stereo  jack (3/32" or 2.5mm diameter).  The pinouts for
these connectors are as follows:

5-pin mini-DIN:
   
        ----------
      /            \      1 = POWER (+6-9 VDC @ 100mA)
     /    4   2     \     2 = Option (Unused on consumer VCR)
    |_      __   1   |    3 = POWER SWITCH
     _|    [__]      |    4 = SERIAL BUS
    |                |    5 = GROUND
     \    5   3     /
      \            /       (Front view of connector on VCR)
        ----------

Stereo sub-mini:

        _ ___+-------+    1 = SERIAL BUS
      O|_|___|       |    2 = POWER (+6-9 V.D.C. @ 100ma)
      ^ ^  ^ +-------+    3 = GROUND

For a translation cable, connect as follows:
