NFORMATION
• The DSU III AR has an 8-position modular jack labeled T
ELCO
. This is used
for connecting to the network when the unit is configured for either dedicated
or switched operation.
• The primary DTE rate is configured from the front panel. The primary DTE
can operate in asynchronous or synchronous modes and should be
connected to either the primary EIA-232 DTE connector or the CCITT V.35
DTE connector. Configuration settings are in Chapter 5 of the User Manual.
• The maximum cable length recommended is 50 feet for the EIA-232. The
EIA-232 connector works up to 56 Kbps with a low capacitance cable or with
the external transmit clock option selected.
• For the CCITT V.35, the maximum cable length recommended is 100 feet.
The V.35 connector is recommended for data rates above 19.2 Kbps.
• If used, the secondary DTE should be connected to the auxiliary EIA-232
connector.
• For pinouts to all connectors, see Appendix A, Pinouts in the DSU III AR User
Manual.
• Additional specific information can be found on the product CD which
contains the DSU III AR User Manual, FAQs, Data Sheets, Applications, and
White Papers.
