Configuration Menu
Used to set communications and other parameters;
four screens in all. Scroll through the parameters
using the up ↑ and down ↓ arrow keys. To get to the
next set of parameters press PAGE DOWN. To
change the value of a parameter, press RETURN.

*NOTE: Synchronous data only.
Stop Bits
The number of stop bits set to read in async mode.
Data Bits
The number of data bits set to read.
Parity
The parity set to read. Choosing Odd or Even
assumes an extra bit at the end of the data bit.
Mode
SDLC, Isochronous
• Async is for asynchronous transmissions.
• Monosync and BSC are byte-oriented sync
protocols. Monosynchronous uses an 8-bit sync
character; BSC uses two 8-bit sync characters.
• SDLC is a bit-oriented sync protocol that uses an
8-bit flag (hexadecimal 7E) to mark the
beginning and end of message envelopes.
• Isochronous is a clocked async mode that allows
asynchronous data to be sent over synchronous
circuits.

The way you would like to view your data.
Sync Char 1
In monosync mode this byte is used as a pad
character on all transmission—output, loop, and
answerback options. To learn how to enter hex
values, see 1.3, Entering Integers and Hex Values.

Sync Char 2
Refers to the second synchronous characters in BSC
mode or the receive synchronous character in
Monosync mode. To learn how to enter hex values,
see 1.3, Entering Integers and Hex Values.
NOTE:
Sync character one and two are loaded
automatically in SDLC mode.
Data encoding
These are the four data encoding methods.
• NRZ is used in sync and async applications.
• NRZI, FM0 (biphase space) and FM1 (biphase
mark) are all used in various sync applications.
Ig Mul Syn Char
(Ignore multiple synchronous characters)
If you select "Yes", this tells the unit not to capture
synchronous characters. If you select "No", this tells
the unit to capture all synchronous characters.
Drop Sync RTS/CD
Select "Yes" to drop synchronization when the
Monitor detects Ready To Send or Carrier Detect.
Resync Char
Selecting "None" has no effect on synchronization.
Setting a (hex value) means synchronization is
dropped when this character is received.
Resync On Char
Selecting "On" drops synchronization when it
detects Ready To Send or Carrier Detect.
Log Events
No, 1Fill, Cont.
Used to keep a log of certain events. See Time Events
(p. 19, Chapter One) on how to view the log.
• "No" means you do not want to keep a log.
• "1Fill" means to fill the log buffer once (when
log buffer is full, stop collecting logs).
• "Continuous" means you want to continue
capturing logs, and when the buffer is full, to
clear logs to make room for newer logs.
