OPERATION

Port 2 (Host Port)
Port 2 is shipped with Host protocol mode set as default. A 9-pin connector labeled “RS232/422 Port 2”,
located above the sync input reference mains, follows an ASCII protocol control. Port 2 in Terminal mode
has these main functions:
 Serves as protocol for PC computer connection (TyLinx Pro)
 Serves as protocol for third-party device
These functions are stored in non-volatile memory on the master processor so that a terminal is not
required unless it is necessary to change a setup. Connections to the 9-pin are shown in the table below.
“Transmit” and “Receive” refer to what is inside the SVS system. Connect to the opposite function at your
end.
9 Pin Serial Connections
Serial Adapter Connections for Older Systems
To configure a routing switcher, a standard computer terminal, or more likely, a PC running a terminal
emulator program such as HyperTerminal, HyperAccess, or Procomm, must be connected to a router
serial port that is running Terminal Protocol. SVS sells interface cables, or you can make your own. If you
choose to make your own, take note of these points:
 The pin out of the 9-pin D connector on the frame is not the same as the pin out of the 9-pin
connector or a typical PC
 Both Terminal & Host Protocols use software flow control, so you do not connect signals like
DTR, RTS, SDR, CTS, or RI. Only three wires are needed: transmit data, receive data, and
signal ground.
Factory default settings: 9600 Baud, 8 Data Bits, No Parity, 1 Stop Bit.
