Solder Bridges
There are several solder-bridges on the backside of the i-PAN7, which modify how some
interfaces of the panel will function.
Solder Bridge
Description
LB5, LB16
Route USB-host port 1 to J30, J32,J33,J34.
LB8
Trizeps IV/V and Trizeps VI/VII use different Ethernet-Phys.
Resistor R242 is in parallel to LB8. R242 or LB8 need to be closed for the
Trizeps VI/VII Ethernet-Phy to function properly.
LB9
Pulls OTG_ID to GND.
Wether the USB-OTG port functions as host or slave depends on
software settings. One software setting is to determine this by the
OTG_ID pin. If it is pulled to GND, than the port functions as host,
otherwise it will work as USB slave.
The onboard USB connector is connected to the USB-OTG port.
LB14, LB15
Use the internal or external connector for the USB-OTG port.

Solder Bridge
Description
LB6
USB-Slave Detect Signal to SODIMM-Pin 55.
Only close for Trizeps IV and V.
LB13
Enable 120R CAN termination.
LB13 is in parallel to resistor R118.
LB11, LB12
Connected to onboard CPLD.
May be used in a custom CPLD-program.
Default CPLD-program does not evaluate these signals.
LB1, LB2
Touch-Interrupt:
LB1: Touch-Interrupt routed to SODIMM-Pin 55
LB2: Touch-Interrupt routed to SODIMM-Pin 45
LB3
Close if HE910 modem is used.
LB7
Connects J10-4 to SODIMM-Pin 43
