Recommended maximum distance limitations

The maximum recommended length of each type of cable connection you may use
with PortServer II are shown below.
Note: Although PortServer II may operate adequately if you exceed a given limita-
tion, performance may be degraded.

Ethernet

10BaseT: Maximum distance of 330 ft (100 M) at a transmission rate of 10
megabits/second (10 Mbps).
10Base2: Maximum distance of 610 ft (185 M) at a transmission rate of 10
megabits/second (10 Mbps).

EIA RS-232 serial ports

Maximum distance depends on the data rate and the type of cable:

V.24 cable
If you are connecting to a Frame Relay service, you require a fully V.24-compatible
cable. Distance limitations are the same as for serial cables.
