SOLIDYNE 562

dsp EVOLUTION

 

2.8.1  Installing and settings 

Before  see  the  detailed  explanation,  an  overview 
on the settings procedure. 

 

a) 

Connect  the  562dsp  to  the  LAN  (Hub,  Switch  or 
Router) using a standard UTP cable. 

b) 

Check  the  IP  address  of  the  unit  using  “DS 
Manager”  software  (this  tool  is  available  into  the 
folder “IP-Access” in the original CD). 

c) 

A PC will be used to run the software and to access 
to  the  562dsp  hardware.  We  call  to  this  PC  “local 
terminal”.  Install in  the  “local  terminal”  the  Solidyne 
VirtualRack software, provided with the unit. If there 
is  a  Firewall  (by  software  or  hardware)  you  must 
enable  port  1101  for  the  communication  with  the 
562dsp. 

d) 

Install in the “local terminal” the ‘Virtual Serial Port’. 
For  make  this,  install  the  IP-ACCESS  pack  from 
Virtual Rack 562 CD-ROM. 

e) 

Run  the  VRack5  software,  it  will  explore  the  first  5 
ports  to  detect  the  audio  processor,  if  not  detected 
you must set the port number in the file 

serial.ini

 

f) 

To access from outside to the LAN, please refers to 
“2.8.3 –Accessing from Internet”  

 

2.8.2.1  Set up 

Connect the 562dsp/IP to the LAN and turn on. Next 
to  the  connector  RJ45  a  green  LED  will  light.  If 
amber  LED  lights  then  the  network  detected  is  of 
100Mbps.  
 
From  setup  CD-ROM  install  the  IP-ACCESS  pack, 
running \IP-ACCESS\Setup.exe. Once installed, run 

‘DS Manager’

 tool, which provides in 562dsp/IP CD-

ROM  (folder  IP-ACCESS).  This  tool  will  show  all 
active units connected to your LAN. Each unit has a 
MAC  address  that  is  unique  and  fixed;  and  an  IP 
address that you can change freely.  

 

 

Select  the  unit  from  the  list  and  press  the  button 
[Settings].  Here  you  can  define  a  new  IP.  In  this 
example the local area network uses  address like 
192.168.0.x,  to  accede  from  any  terminal  of  that 
network to 562dsp/IP you need that IP address is 
compatible.  Assign  a  fixed  IP  that  it  does  not 
generate  conflicts  with  another  terminal  (in  the 
example 192.168.0.11).  

If  you  have  a  DHCP  server  you  can  obtain  a 
dynamic  IP  address,  although  if  IP  changes 
frequently will require changes in the configuration 
of  the  clients  (or  in  the  LAN  like  for  the  access 
from Internet).

  

 

 

Assign 

the 

Gateway 

address 

(usually 

192.168.0.1),  and  the  subnet  mask.  This  is 
needed  if  you  wish  to  accede  to  the  562dsp/IP 
from  outside  of  the  LAN.  If  you  don’t  know  these 
values, contacts to your network administrator.  
 
The  port  used  is 

1101

.  You  can  change  it  if 

conflicts  with  another  application  appear  in  the 
terminal  client  who  uses  the  same  port,  but  this 
rarely occurs. 

 

 

¡NEVER PRESS THE BUTTON “INITIALIZE”! 

THIS 

OPTION

 

WILL CHANGE CRITICAL VALUES FROM 

FACTORY DEFAULTS.

 

 
Critical default values:  

 

 

In  the  section  'Connection', 

Transport Protocol 

= TCP 

(default value). 

 

In  the  section  'Connection', 

Inband  commands 

= 0 (dissabled) 

(default value).  

 

In  the  section  'Serial  Port', 

On  the  fly 

commands  =  1  (ennabled) 

(default  value).  If 

disable it applications can not set the baud rate.  

 

In  the  section  'Serial  Port', 

'DRT  Mode  =  1 

Indicate connection status'

 (default  value).  It’s 

a critical  value.  If is changed communication will 
fail.
