DMD15/DMD15L IBS/IDR Satellite Modem User Interfaces
TM051 - Rev. 5.8 5-3
5.2 TX (J1)
If the customer orders the 70/140 MHz IF, the Transmit IF Output Port will be a 75-Ohm Female
BNC Connector. The power level is programmable from -20 to +5 dBm in 0.1 dBm steps. The IF
Frequency can be programmed to 50 – 90 MHz or 100 – 180 MHz, in 1 Hz steps. If an L-Band IF
is ordered, the IF Port will be a 50 Ohm SMA Female Connector. The power level is
programmable from -30 to -5 dBm, in 0.1 dBm steps. The IF Frequency can be programmed to
950 – 1750 MHz, in 1 Hz steps.
Note: A receive only option of the DMD15/DMD15L is available. When this option is
ordered, there will be no TX Port on the Back Panel.
5.3 RX (J2)
If the customer orders the 70/140 MHz IF, the Transmit IF Output Port will be a 75-Ohm Female
BNC Connector. The power level is programmable from -20 to +5 dBm in 0.1 dBm steps. The IF
Frequency can be programmed to 50 – 90 MHz or 100 – 180 MHz, in 1 Hz steps. If an L-Band IF
is ordered, the IF Port will be a 50 Ohm SMA Female Connector. The power level is
programmable from -30 to -5 dBm, in 0.1 dBm steps. The IF Frequency can be programmed to
950 – 1750 MHz, in 1 Hz steps.
5.4 SD (J3)
The Send Data Port (Unbalanced) is a 75-Ohm Female BNC Connector.
5.5 DDO (J4)
The Drop Data Out Port (Unbalanced) is a 75-Ohm Female BNC Connector.
5.6 IDI EXC (J5)
The Insert Data In Port (Unbalanced) is a 75-Ohm Female BNC Connector.
5.7 EXT CLK (J5) – Synchronous Interface Only
The External Clock In Port is a 75-Ohm Female BNC Connector that is located on the
Synchronous Interface Module only.
5.8 RD (J6)
The Receive Data Port (Unbalanced) is a 75-Ohm Female BNC Connector.
5.9 G.703 (J7)
The G.703 Interface Port (Balanced) is a 15-Pin Female “D” Connector. Refer to Table 5-1 for
pinouts.
