     Support for the LeCroy 4222 delay module was recently added.  You are
both interested in the SSDN:


		+-----------------------+
		|	    0		|
		+-----------------------+
		|     0     |  22 (hex) |
		+-----------------------+
		|  crate    |   slot    |
		+-----------------------+
		| 22 (hex)  |	channel	|
		+-----------------------+

     You get only a setting property.
     
     Channel is 0-3 (delay channel)

     The data length must be exactly 4 bytes (2 words).

     Note that Dec-T fakes in the constant 170 ns delay.  Thus if you
try to set a delay of less than 170 ns (a camac setting of 0) Dec-T
will clamp it at 170 ns.  Thus, for instance:

	User types in 200 ns on a parameter page
	Parameter page sends 200 to Dec-T
	Dec-T subtracts the 170 ns offset and writes 30 to the card
	Card runs with a delay of 30+170 = 200 ns
	Dec-T reads 30 from the card, adds 170, and reports back 200 ns
