STM-2XM Operating Manual
Test Mode . . . . . . . . . . . . . . . . . . . . . Test mode provides simulated sensor
readings.
NOTE: If STM-2XM is reset, test mode is
turned off automatically.
Active Source
(Active Channel) . . . . . . . . . . . . . . . . For single film modes, this selects where the
analog and digital outputs and inputs are
connected (refer to
section 2.2 on page 2-3 ).
Display Mode. . . . . . . . . . . . . . . . . . . Displays thickness in kiloangstoms (kÅ) or
mass in micrograms per square centimeter
(µg/cm
3
).
Plot type. . . . . . . . . . . . . . . . . . . . . . . Available in single film modes.
Displays the graph on the Runtime screen as
None, Rate Deviation, Rate, or Thickness.
Plot time scale. . . . . . . . . . . . . . . . . . Sets the horizontal axis size. Defines the
amount of time covered by the plot before it is
overwritten.
LCD Contrast
LCD Brightness. . . . . . . . . . . . . . . . . Adjusts the appearance of the screen. Set the
brightness to 100%, and then adjust the
contrast until the display is easily read.
Brightness can be programmed to a desired
level.
NOTE: The screen dims when STM-2XM is
idle.
Beep [on/off] . . . . . . . . . . . . . . . . . . . Turns the button/control knob beeper on or off.
Comm Protocol . . . . . . . . . . . . . . . . . Serial communications mode to STM-2XM,
Sycon 9600 (9.6 Kbps), SMDP L (9.6 Kbps),
SMDP M (38.4 Kbps), and SMDP H (115.2
Kbps).
If the protocol selected is Sycon 9600,
STM-2XM performs serial communication with
Sycon protocol at 9600 baud, using RS-232
electrical levels.
If the protocol selected is SMDP, STM-2XM
performs serial communication using SMDP
protocol at 9600, 38400, or 115200 baud.
