Connections
The 400 DDS rear panel has three interface connectors: an RJ-48C DDS network
connector, a V.35 high speed port connector, and an RS-232 connector. Each unit
comes equipped with a power cord for 115 VAC operation (±10%).
DDS Network Connection
The network DDS facility interface is a standard RJ-48C (8-pin) modular jack with
the following pinout:
V.35 and RS-232 Port Connection
The V.35 or the RS-232 port is automatically selected when you physically connect
the cable to the port. Connection to only one of these two connectors is allowed at
any one time because the internal circuitry selects the proper interface depending on
which connector has TXD applied. These ports meet all the general physical and
electrical requirements. The V.35 connector is a standard 34-pin female. The RS-
232 connector is a standard DB-25 female.
The V.35 and RS-232 pin assignments are shown in the previous table. Only cir-
cuits serviced by the unit are listed. When two pins are listed, the first is the A differ-
ential pin and the second is the B differential pin. All balanced bipolar inputs and
outputs meet the physical and electrical specifications at ITU V.35. All unbalanced
bipolar inputs and outputs meet the physical and electrical specifications of ITU
V.28.
