2.2.8 Handheld Remote Front Panel

The optional Handheld Remote Front Panel (HHRFP) implements the traditional 16 button keypad and
4x40 character LCD user interface, but allows a much longer distance than what could be achieved by
directly connecting to the LCD and keypad connectors on the computing card.
The HHRFP allows the keypad and display information to be communicated to/from the RC4000 via serial
port (RS-422) or Ethernet port. There is an interface card within the HHRFP that handles the
serial/Ethernet protocol, as well as driving the LCD and monitoring user key inputs.
NOTE: the HHRFP is pictured above in a weatherproof enclosure supplied by RCI. The HHRFP
components (LCD, keypad and interface card) may also be purchased without an enclosure for
incorporation into a user defined panel. The LCD may optionally be replaced with a VFD (vacuum
fluorescent display) for a wider temperature range (as shown above.)
