2.5Shunts

V.35 signal levels are generally more reliable for high speed data and/ or longer cable distances. EIA-232D signal levels are intended for data rates of 19,200 bps or less and cable lengths of 50 feet or less. For higher speeds and/or longer distances, V.35 is generally preferred.

There are two shunt positions on the printed circuit board that configure the data port for either RS232 or V.35 interface. Both DIP sockets for the shunts are shown in Figure 2-4.

In Figure 2-3, the shunt is shown in the RS232 (default) position (i.e., in the right-hand DIP socket - the one closest to the DIP switches. To change the location of the shunt, refer to the V.35 Shunt procedure in Chapter 3.
