FIELD CONNECTIONS

The USB22 is available in four models that vary by transceiver type for

connecting to an ARCNET LAN via a particular kind of cable. Each

model's transceiver is identified by the suffix (-4000, -485, -CXB or -

TB5) separated from the main number by a hyphen.

-CXB Coaxial Bus

Generally two types of coaxial cables are used with ARCNET: RG-62/u

and RG-59/u. RG-62/u is recommended because it matches the 93-ohm -

CXB impedance and can thus achieve the maximum 1000-foot segment

distance. Although RG-59/u does not match the -CXB impedance (it is

75-ohm cable), it will still work but the segment length may be limited.

Never attach coax cable directly to the USB22-CXB; always use the

provided BNC "T" connector. The "T" connector allows the coaxial bus

to continue as shown with device A in Figure 3. Apply the provided 93-

ohm BNC terminator to the "T" if the USB22 terminates the coax in an end-

of-line situation as shown with device B in Figure 3.
