ROUTING SWITCHER SYSTEM (E)

*

1: The specifications of BKPF-R70.  When BKPF-R70 is used, termination resistors are necessary at both ends of the cable.  The cable

cannot be checked for open circuit.

*

2: Known before as switcher protocol.

The DVS-V3232B/V6464B and HDS-V3232 digital video routing switcher is equipped with four kinds of
remote ports REMOTE 1 (S-BUS), REMOTE 2 (9-pin), REMOTE 3 (25-pin), and REMOTE 4 (monitor

S-BUS). Other switchers are equipped with three kinds of remote ports excluding REMOTE 4.

The specifications and functions of the control ports are as follows.

Function

With this port the communication between the primary and secondary stations is performed.

Remote control units, routing switchers and display units are connected to this S-BUS data
link in order to perform system functions.

REMOTE 1 is sometimes simply called “remote” for units having this remote port only.
To distinguish the S-BUS using REMOTE 1 from the monitor S-BUS (REMOTE 4), which

will be described later, it is called standard S-BUS or simply S-BUS.

Function

With this port communication between two units is performed. A switcher, DME, etc. are
connected to this port. The functions of the router system using this RS-422A port depend

on a superior controller so that the system may not have so many functions as S-BUS
system’s.
