PIN Function Description
1 UART1_TXD / USB 1.1 – Default Host
RS232 or UART2 – Alternative Setting
NOTICE: When Expansion Head is connected –
the connection is USB1.1. UART2 is configured
on DB9 interface on the expansion Head. The ra-
dio monitors DB9 interface to detect cable con-
nection/disconnection based on PIN voltage level
of RX and DTR lines. When Expansion Head is
not connected – the connection can be config-
ured to UART2 in the CPS codeplug (default set-
ting is USB1.1).
NOTICE: If it is not a radio with BSI SW, then us-
ing codeplug setting it can be changed to UART2,
else it is USB1.1.
