Setting the SELF ADDRESS Dipswitches
The SELF ADDRESS determines the position of a
VS-88HCB unit in the
sequence, specifying which
VS-88HCB unit is being controlled when several
VS-88HCB units are controlled by a PC or serial controller. Set the SELF
ADDRESS on a
VS-88HCB unit via DIPS 1, 2, and 3, according to Table 4.
When using a stand-alone
VS-88HCB unit, set the SELF ADDRESS to 1
When connecting more than one
VS-88HCB unit, set the first machine
(the Master) connected via RS-232, as SELF ADDRESS # 1. The Master
connects to the PC via the RS-232 port. The other
VS-88HCB slave units
(each set to a SELF ADDRESS # between 2 and 8) interconnect via their
RS-485 ports to the RS-485 port on the Master

Setting the Reply Dipswitch
Dipswitch #5
(the Reply dipswitch) enables or disables a reply from the
VS-88HCB to the PC.
This is desirable, so that the controlling device “ knows” that the controlled
device has carried out its instructions. When an RS-485 connection is used for
communication between the Matrix Switcher and the PC, dipswitch #8 should
be set to OFF. In some applications, it may be desirable for some machines
not to reply to instructions received on the RS-232 and RS-485 ports. In this
case, the
Reply, or acknowledgement commands should be disabled.
6.5.3
Setting the RS-232/RS-485 Dipswitch
The RS-232/RS-485 dipswitch allows you to enable RS-232 communication
between the Matrix Switcher and the PC.
