Specifying flow control
settings
Determine whether the device you will connect the E1/Datacom Tester to uses
flow control. If so, you can configure the E1/Datacom Tester for out-of-band
flow control. If you are testing in asynchronous mode, you can also use in-band
flow control. When you enable out-of-band flow control, you can specify
whether data is transmitted based on specific signal lead conditions.
To specify flow control settings
1 If you haven’t already done so, launch the Data Communication applica-
tion (see
“Launching the datacom application” on page 52 ).
2 On the Configuration menu, select Flow Ctrl Settings , and then specify
values for the following settings:
Setting Parameter
Parity – None
– Even
– Odd
Note: Selecting Odd or Even adds one bit to each charac-
ter to accommodate the parity bit. For example, 7 data bits
with even parity encoding generates 8 bit characters.
Data Bits – Data 5 for baudot encoding
– Data 6 for BCDIC encoding
– Data 7 for ASCII encoding
– Data 8 for EBCDIC encoding
Stop Bits – 1
– 1.5
– 2
Setting Parameter
Oob Flow Control Select On to set out-of-band flow control; Off uses
