9 Gateway 8/16 Rear Panel Connections
Supplementary Ground Terminal
Supplementary ground terminal for connecting the unit to a ground connection. See Warnings and
Safety Information for more details.
Dual Redundant AC Power Inputs
The codec is powered by dual 90-240 volt, 2A/50-60Hz redundant AC power supplies, which use
standard IEC connectors.
Shared Analog and AES3 Inputs and Outputs
Balanced ANALOG/AES3 IN RJ-45 connectors provide shared stereo analog line inputs 1-4 (analog
inputs 1-8), or stereo AES3 digital inputs 1-4 (AES3 inputs 1-8). Plus, connectors 5-8 provide stereo
AES3 digital inputs 5-8 (AES3 inputs 9-16). Balanced ANALOG/AES3 OUT RJ-45 connectors
provide shared stereo analog line outputs 1-4, or stereo AES3 digital outputs 1-4, plus stereo AES3
digital outputs 5-8.
Module Slot
A module slot supports the optional Gateway Euro ISDN module, as well as future hardware and
technology upgrades.
Configurable BNC Sync I/O Connectors
Two BNC type SYNC I/O connectors for Word Clock and other synchronization with external
sources.
Dual DB-25 Control Port Connectors
Dual female DB-25 CONTROL PORT I/O connectors support 16 CMOS control inputs and 16 opto-
isolated solid-state relay outputs. DB-25 pinouts are available in Appendix A.
Dual Gigabit AoIP Ports
Two Gigabit (10/100/1000) RJ-45 AoIP ports for AES67 or optional WheatNet-IP streaming (16
bidirectional mono or 8 bidirectional stereo). Note: Port 2 not operational in early firmware releases.
Dual Gigabit Ethernet Ports
Two Gigabit (10/100/1000) RJ-45 Ethernet LAN ports for IP connections. By default, the codec
assumes LAN1 is the primary LAN connection and LAN2 is the backup LAN connection when in
