Note
If the command is sent without an appended relay number, then all
the relays are assigned the set logic of normally open/closed.

Send:
set relay open 1

set relay open 1 ok
The erec, lrec, and srec layouts contain the following:
●
A format specifier for parsing ASCII responses
●
A format specifier for parsing binary responses,
In addition to these the erec layout contains
●
A format specifier for producing the front-panel displays.
In operation, values are read in using either the ASCII or binary format
specifiers and converted to uniform internal representations (32-bit floats
or 32-bit integers). These values are converted into text for display on the
screen using the format specifier for the front-panel display. Normally, the
specifier used to parse a particular datum from the input stream will be
strongly related to the specifier used to display it (e.g., all of the floating
point inputs will be displayed with an 'f' output specifier, and all of the
integer inputs will be displayed with a 'd' specifier).
The first line of the Layout response is the scanf-like parameter list for
parsing the fields from an ASCII ERec response. Parameters are separated
by spaces and the line is terminated by a \n (the normal line separator
character). Valid fields are:
%s - parse a string
%d - parse a decimal number
%ld - parse a long (32-bit) decimal number
%f - parse a floating point number
%x - parse a hexadecimal number
%lx - parse a long (32-bit) hex number
%* - ignore the field
Note
Signed versus unsigned for the integer values does not matter; it is
handled automatically.

The second line of the Layout response is the binary parameter list for
parsing the fields from a binary response. Parameters MUST be separated
by spaces, and the line is terminated by a '\n'. Valid fields are:
t - parse a time specifier (2 bytes)
D - parse a date specifier (3 bytes)
