(1) Change SYNC speed:

This selection determines the data rate in Kbps of data entering and leaving the WINC 2400C over
the synchronous port. The data rate ranges from 9600 bps to 128 Kbps. Please note that once the
selection is made, it takes effect instantly. In addition, this selection is only valid when the WINC
2400C provides the clock, i.e., items 3 and 4 setting are at internal.

(2) Change interface type:

Three types of physical interfaces, RS-232, V.35 or RS-422, are available for synchronous operation.
This selection allows the user to choose from the list.

(3) Change Tx (Transmit) clock source:

This selection determines whether the WINC 2400C (considered the DCE) provides the transmit
clock (internal) to the DTE or receives the transmit clock (external) from the DTE . The choice of
internal is recommended.

(4) Change Rx (Receive) clock source:

This selection determines whether the WINC 2400C (considered the DCE) provides the receive clock
(internal) to the DTE or receives the receive clock (external) from the DTE. Again, the choice of
internal is recommended

(5) Change Peer Address:

This 7-digit number represents the address of the modem in remote to which a link is established.
The address is on the sticker attached to the side of the remote unit.

(6) Change Channel Number:

Operating in the synchronous mode, twenty (20) 4-MHz channels are available for communications.
After you make your selection, you must coordinate that choice with the distant end and use this menu
to select the idential channel.

(7) Change operation protocol:

This selection determines whether the synchronous interface between the DTE and the WINC 2400C
(DCE) is transparent (i.e. no meaning is associated with any bit or bit sequence) or HDLC (i.e. a
“bit-oriented” protocol in which data bits are “framed” by standardized bit sequences). For proper
operation the DTE and the DCE should be configured identically. Note that the system must be reset
for this change to take effect. We recommend transparent.

(8) Change power level:

Using this selection you can choose any one of four transmission power levels, if available.
Otherwise, the selection is not operative.

(9) Change FEC Check Operation:

When operating synchronously, forward error correction (FEC) is used to improve the link
performance. This selection determines whether only error-free packets are passed to the DTE (FEC
ON) or whether all packets are passed (FEC OFF), i.e. even those packets with known errors are
passed to the DTE.

(A) Change Master - Slave mode:

For proper operation of the system, one unit must be designated as the master unit and the other as
the slave. This selection is used to make such a designation. Note that the system must be reset
before this instruction takes effect.

(B) Change air Time-Out value:
