Serial Port Configuration
The serial communication port "uart2:", "uart3:", or "uart4:" are confi g-
ured for RS-232 as standard but can be reconfi gured for two other types
of serial communication by fi tting certain driver circuits and straps. The
circuits can be ordered separately from Intermec:
• RS-422 isolated, full duplex
• RS-485 isolated, half duplex ("uart2:" only!)
RS-232 Non-isolated (standard)
Strap fi tted on J2 A
