Base Station to Component Wiring
Good Wiring Practices
To reduce interference and improve signal quality, use the following practices
for all communication wiring:
• Keep shielding on the cable as close to the terminal as possible.
• Do not untwist pairs more than necessary.
• Do not allow cable strands to fray.
• Do not tin cable leads with solder.
• Fold un-insulated wire over onto itself before inserting into a terminal.
• Make sure screw terminals are tight.
A minimal, typical arrangement of the components is shown in Figure 8:
2_SPKR_OUT+ Positive phase order point speaker for Lane2
2_SPKR_OUT- Negative phase order point speaker for Lane2
2_GRT_CNL
(GPIO16) Active low talk. Must use one of the GND0 or GND1 from GPIO
terminal block
2_GRILL+ Positive phase grill monitor speaker for Lane2
2_GRILL- Negative phase grill monitor speaker for Lane2
2_NO Connect to relay 2 if normally open relay
2_COM Relay 2 common
EXT_AUDIO: 4 auxiliary, ‘line level’, audio ports. All of the wires on this terminal block go to the external audio
1_LOUT
Connects to IN on external device. Allows amplification/recording of all Lane 1
audio channels (Inbound, Outbound, PAGE)
2_LOUT
Connects to IN on external device. Allows amplification/recording of all Lane 2
audio channels (Inbound, Outbound, PAGE)
GND Ground
1_LIN
Connects to OUT on external device. Audio can be used to record Greeter
Message for Lane 1 and to provide audio to Lane#2 Headsets/Grill Speaker.
2_LIN
Connects to OUT on external device. Audio can be used to record Greeter
Message for Lane 2 and to provide audio to Lane#2 Headsets/Grill Speaker.
GND Ground
AUXILLIARY AUDIO:
