Rear Panel Connections
All IPSat GW1000 external connections are located on the rear panel.
IPSat GW1000 Rear Panel
External Input Power Supply Port
The DC Power In port supplies up to 48 VDC at 6 amps to the IFL cable for external (UPA).
Connector: Mini-UHF connector
Transmit Out Port
The TX Out port provides the transmit IF output, reference, and DC power to the ODU transmitter. The IPSat
GW1000 modulator has electronically adjustable output power. For normal IPSat GW1000 operations, the output
power of the L-band modulator is set between –35 and 8 dBm, in 0.1 dB steps. The output frequency is
programmable in the range of 950 to 1750 MHz.
The output impedance is 50 ohms, with a return loss of 8 dB or better.
Connector: Mini-UHF connector
Optional Power Detector Port
The Tx/Rx port uses a Y-cable to interface with optional power detector and/or user data equipment. This port
provides DC and receives a 4 to 400 KHz signal for the optional BUC power detector for closed loop power control.
Connector: DB26 HD
Receive Input Port
The Rx In port receives the L-Band IF signal for the ODU and provides DC power to the ODU LNB. The power of
the input signal must be in the range of –30 to –65 dBm. The IF frequency must be in the range of 950 to 1750 MHz.
The input impedance is 75 ohms, with a return loss of 8dB or better.
Connector: F connector
Audio Output Ports Left and Right
The Audio Left and Audio Right Output ports supply the analog audio outputs for audio channels 1 and 2. The peak
output level is approximately –3 dBu and the output are matched for 600-ohm impedance.
Connectors: stereo pair on RCA jacks, +18 dBU maximum, 0 dB throughput gain nominal.
Video Output Port
The Video Output port supplies the composite analog (NTSC or PAL) video output signal to the user monitor. The
output impedance is 75 ohms. Connector: RCA jack.
Console Port
The Console port provides an RS-232 interface between the IPSat GW1000 and a console.
Connector: DB 9 connector
Ethernet Port 10/100 BaseT Port
The Ethernet 10/100 BaseT port supports auto-negotiation by default. Optionally, speed and duplex can be manually
set.
Connector: 10/100BaseTX per IEEE 802.3u on an RJ-45 connector.
Power Supply
The rear panel AC power supply interface includes an On/Off (I/0) power switch, a cooling fan vent, and an IEC
320 power cord receptacle.
The IPSat GW1000 is powered by an auto-sensing, auto-ranging AC switching power supply. The power supply
accepts 85 to 240VAC nominal input voltage levels cycling at 47 to 63 Hz.
