     I misplaced your description, but I believe this is what you wanted.

     The 166 SSDN looks the same for all properties:

		+-----------------------+
		|	    0		|
		+-----------------------+
		|      0    |  32 (hex) |
		+-----------------------+
		|  crate    |  slot     |
		+-----------------------+
		|  32 (hex) |     0	|
		+-----------------------+


     The various data base properties map onto the module camac
functions as follows:


	Function   Property		Meaning
	--------   --------		-------

	F(2)A(0)   READING		EXTERNAL TRANSMIT DATA REGISTER
	F(16)A(0)  SETTING		CAMAC TRANSMIT DATA REGISTER
	F(0)A(0)   READ-THE-SETTING	  "      "      "      "
	F(1)A(0)   BASIC STATUS


     For the basic control property you send one word containing
a code as follows:

      Code Function	Meaning
      ---- --------	-------

	1  F(24)A(0)	ENABLE CAMAC TRANSMISSION / DISABLE EXTERNAL
	2  F(26)A(0)	DISABLE CAMAC TRANSMISSION / ENABLE EXTERNAL
	3  F(9)A(0)	RESET
	4  F(28)A(0)	EXTERNAL TRANSMISSION OFF
	5  F(30)A(0)    EXTERNAL TRANSMISSION TRIGGER ON


     This is all implemeted, but exists only in Dec-P at the moment.
It should go into Dec-T and Dec-S sometime Thursday or Friday.

     If I got anything wrong, it is trivial to change it.
