TX Invert Clock Data is received from the customer’s equipment on the other clock edge.
Values: Disable, Enable
Default: Disable
NOTICE: You will need to change this parameter if the propagation delay on the
serial cable causes data errors. This acts as a manual data aligner.
RX Invert Clock
(Applies to Serial 2
Screen Only)
The Rx Invert Clock parameter is only available for use in DTE Mode on the
Serial 2 port. Consequently, this configuration option should remain disabled
when configuring services for the Serial 1 port. Data is sent to the customer’s
equipment on the other clock edge.
Values: Disable, Enable
Default: Disable
Tx Clock Selects the clock the unit uses to sample the data transmitted from the DTE.
When set to “Internal,” the data is sampled directly with the transmit data
clock that is also supplied to the DTE as Transmit Clock. The “External”
option uses the external clock from the DTE.
Values: Internal, External
Default: Internal
NOTICE: The “External” option is valid only in Packet Mode.
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
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
CTS The Clear to Send (CTS) parameter can be set to “Forced True,” “Forced
False,” or “Internal.” If this parameter is set to “Internal,” the CTS control
lead follows the Request to Send (RTS) control lead from the DTE after a
delay of a duration established by the RTS/CTS Delay parameter (see RTS/
CTS Delay on page 4-18).
Values: Forced True, Forced False, Internal
Default: Forced True
