Gateway Board Connections
To Make a USB Connection
On the Gateway Side
1. Connect the USB-C side of the cable to the USB port of the gateway.
The USB port is labeled as 8 in the figure
“Gateway Connections” on page 14
.
On the Panel Side
1. Connect the USB-A side of the cable to the USB port of the panel.
To know more about the panel-side connection steps, refer to the installation document of the respective
panel.
Power Connection
After connecting the gateway to the panel through USB, connect the gateway with an external power
source for its 24V DC power.
To Make a NUP/RS232 Connection
On the Gateway Side
1. Connect the NUP cable to the NUP port of the gateway board.
The NUP port is labeled as 6 in the figure
“Gateway Connections” on page 14
.
2. Find the SW7 switch next to the NUP port, and switch it to towards NUP_IN.
Figure 3.4: DIP Switch
On the Panel Side
Connect the NUP cable to the NUP port of the panel.
Power Connection
The panel supplies the 24V DC power to the gateway board through the NUP connection.
To Make a UART/TTL Connection
A UART/TTL interface can connect the gateway board with the UART/TTL port of the panel.
On the Gateway Side
1. Connect the male UART/TTL cable to the Rx (Red), 0V (Silver), and Tx (White) terminals of the gateway.
The UART/TTL port is labeled as 5 in the
“Gateway Connections” on page 14
.
On the Panel Side
1. Within the panel, find the backplane PCB board.
2. Connect the 1.5mm phono socket to the P11 connector on the panel’s PCB.
NOTE: This external power connection should be power limited, UL864-listed, and approved for fire alarm
signaling.
