LL The Local Loopback (LL) parameter can be set to “Enable” or “Disable.”
Selecting “Enable” allows the unit to go into Local Loop when the LL pin on
the Serial port goes high. The unit exits the loop when the LL pin goes low. If
you select “Disable,” the unit ignores the LL pin on the Serial port.
Values: Disable, Enable
Default: Disable
NOTICE:
For more information on pin assignments, refer to Network 1 Interface
Pin Assignments on page A-9 and Network 2 Interface Pin Assignments
on page A-9.
V54 Selecting “Enable” allows the unit to respond to in-band V.54 loop codes. If
you select “Disable,” the unit ignores these codes.
Values: Disable, Enable
Default: Disable
DTR Alarm Control Lets you set DTR Alarm Control parameters. Selecting “Enable” allows the
unit to go into alarm on loss of DTR, which occurs when the Serial port
detects that the DTR signal is low.
Values: Enable, Disable
Default: Disable
DTR Alarm Status Lets you view the current DTR Alarm status.
Format Selects the port’s operating mode.
Values: Sync, Async
Default: Sync
Flow Control Selects the type of flow control to be used if the port is asynchronous.
Values: None, Xon/Xoff, RTS/CTS
Default: None
Character Size Selects the number of bits required to make up one asynchronous character.
Values: Five, Six, Seven, Eight
Default: Eight
Parity Sets the parity bit if the port is asynchronous.
Values: None, Odd, Even
Default: None
Stop Bit Selects the number of bits required to end the character.
Values: 1, 2
CTS The Clear To Send parameter can be set to “Forced True,” “Forced False,” or
“Internal.” If this parameter is set to “Internal,” the CTS control lead follows
the RTS control lead from the DTE after a delay of a duration established by
the RTS/CTS Delay parameter. (See RTS/CTS Delay shown on page 4-16)
Values: Forced True, Forced False, Internal
Default: Forced True
