The Serial Adapter Box - Murata Hn-210 Manual

The Serial Adapter Box

The HN-210 and HN-210X remotes interface with the user's hardware through a
serial adapter box. The interface adapter supplies power and signal to the remote
unit. The interface to the remote unit is a standard RS-232 DB-9 serial interface. To
have all functions of the HN-210 available, including configuration and hardware
flow control, the eight signal lines must be connected. The HN-210 serial connector is
set up as a DCE device. This allows communication with a PC using the straight
through serial cable provided with the HN-210. To connect the HN-210 to another
DCE device, a cross-over cable must be used. The connector pin-out is detailed in the
figure and table below.
