1 Use the tab key to move to a Set field. Type an x or X to select the set. The timer
values are defined by the set of values that you choose.
• Set 1: Normal timer mode for release 2.2 (and above) of the MPE/iX FOS.
This is appropriate for most users operating in a normal LAN environment.
• Set 2: Short transmission timer mode for LAN environments where there is
a high number (greater than 1%) of packets lost on the LAN. The values are
adapted to provide shorter retransmission timer values, and higher numbers
of retries.
• Set 3: Long retransmission timer mode for LAN environments where the
LAN is very reliable. The values are adapted to reduce LAN traffic and host
driver overhead.
• Set 4: Variable Retransmission Timer Mode for exceptional cases where
there is a very high percentage of packets lost on the LAN. The values are
adapted to prevent saturation of the LAN.
• Set 5 and Set 6: for other configurations.
2 Press the Done (F4) function key to return to the Rear Panel Configuration
screen.

the Exit Task function key to leave the DTC Manager menu-driven user
interface. You are asked several questions to confirm your configuration. To
activate your changes you can either:
• Type y to the question: Do you want to reset the DTC 16RX now?
or
• Type the following command later at the prompt:
