* 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.

1-2-1. Specifications and functions of control port
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.
REMOTE 1 BNC 75 Z Z Z Z Z 47 k Z Z Z Z Z terminated
Protocol S-BUS control
Data Transfer Method BI-PHASE SPACE
Data Transfer Speed 312.5 kbps/1250 kbps *1
Max Cable Length 500 m/125 m *1 (BELDEN 8281 cable or equivalent)
FCS Data HDLC CRC-CCIT x 16 + x 12 + x 5 + 1 Initial all high
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.
REMOTE 2 D-sub 9-pin
Protocol RS-422A Flow control, 38.4 kbps, 100 Z /10 kZ
This port accepts three kinds of protocols.

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.
