Quick Reference/Quick Setup
Exclude
Off, Control Data, Text Data
Off—has no effect on capture.
Control Data—the control data will be excluded
from the capture (in other words, only the data
between the start text character (STX) and the end
text character (ETX) will be captured.)
Text Data—text data will be excluded from the
capture; in other words, the data between the start
text character (STX) and the end text character
(ETX) will not be captured.
Start Txt Char
(value)
See “Exclude” above. Specify the STX character.
End Txt Char
(value)
See “Exclude” above. Specify the ETX character.
Remote
Off, On
Insert this unit into an RS-232 circuit, then turn on
remote with this menu function to take remote
control of this unit. Useful for loopback tests when
you don’t have an assistant in the remote location.
Remote Baud
57600, 19200, 9600, 4800, 2400,
1200
Communication rate with the remote Monitor Plus.
Invert Rec. Bits
Yes, No
Yes—inverts the sense of all incoming bits.
SDLC Status
Yes, No
Yes—displays status of SDLC.
CRC Preset
Zeros, Ones
Presets the value of CRCs to “ones” and “Zeros”.
SDLC Search Node
Search Node All, Node number
(hex value)
Choosing “All” (0) captures all nodes. Setting a
specific Node number allows you to specify one
SDLC node in a loop or polled circuit.
SDLC Search
Disable, Enable
Choose enable to go ahead and search for the node
specified above in SDLC Search Node.
Status Messages
Normal, Long, None, Short
Notifies you of events when “Normal” is selected;
e.g., END OF BUFFER. Turn them off (None), view
briefly (Short), or linger on the screen (Long).
Idle Display
On, Off
“On” displays “Waiting for data” on power up.
Error Messages
Fatal, Warn, None
NOTE:
When the 232 Monitor Plus is turned on, it
will always pass data through itself, even if
it cannot recognize speed or other
configuration parameters.
Fatal— the Monitor stops receiving at certain
hardware errors (a change in line speed, etc.); press
any key to begin receiving again. You can enter
Configure Menu and change a parameter.
Warn—a message will appear at certain hardware
errors, but receiving will continue.
None—suppresses error messages.
Suppress Capture
Off, RD, TD, Both
Choose whether you want data captured as follows:
Off
Capture data from both lines
RD
Don’t capture RD data.
TD
Don’t capture TD data.
Both
Disables capture on both lines. Useful
when collecting modem control trans-
itions and hardware handshake changes.
Auto Off (min)
(value)
Setting a value means the unit will turn itself off after
it has been idle for (
value
) number of minutes.
Display Mode
Compressed, Expanded
Compressed—data line characters displayed
sequentially to conserve display space.
Expanded— data line characters followed by a blank
to facilitate reading at high speeds.
Buffer
One fill, Continuous
One Fill—stop collecting data when buffer is full.
Continuous—continue to fill the buffer and discard
the oldest data on a first-in/first-out basis.
