USN52 L Operating Manual Page 121
16.10 Remote Control of the USN52 L
The USN52 L is capable of receiving coded instructions from a
personal computer or terminal connected to the RS-232 I/O port.
Instructions must be transmitted to the USN52 L as escape se-
quences, that is, a series of keystrokes, the first of which is always
the Escape key (ASCII 27). The Escape key will be identified in
this manual as [Esc].
Every key press and menu function of the USN52 L can be oper-
ated by remote control. In addition, the current value (setting) of a
particular function may be requested.
This section provides general instructions on command sequence
format. Function codes, along with the values for the options as-
sociated with the functions, are provided in tables in this section.
To execute a keypad operation or adjust the setting of a menu
function, transmit the required escape sequence using the format
below. Refer to the tables later in this section for the 2 digit code,
acceptable value range, and resolution.
«[Esc]»«Code»«Space»«Value»«[Return]»
[Esc] = Escape Key - CHR$(27)
Code = 2 digit code from the tables
Space = Space bar
Value = Desired value from the tables*
[Return] = Enter Key - CHR$(13)
Values must be entered as a multiple of the resolution shown in
the table for each function. As an example, the following sequence
would adjust the RANGE of the USN52 L to 5.000 inches:
«[Esc]»«DW»«Space»«5.000»«[Return]»
