Configuration: Passthrough
The TCP/IP network can serve as an intermediary between two VBricks and their serial
ports or between a PC application sending IP packets and a VBrick's serial port. Passthrough
can be configured using addresses on Ethernet. Passthrough on COM2 is only available on
VBricks with a CPLD (programmable logic device) Version greater than 21. (To check the
CPLD , go to
Status > System Information > CPLD Version
.) If the IWS screens do not provide a
COM1 or COM2 selection at the top of the Passthrough screen, the VBrick defaults to COM1. This
feature supports a wide range of serial applications. See "Serial Port Passthrough" in the
VBrick Appliance Getting Started Guide for more about serial port passthrough. Note that RS-
232/422/485 end-to-end control is initiated by enabling or disabling Passthrough. The
Passthrough port for COM1 is 4439; the port for COM2 is 4414.
Configuration: Passthrough > COM1
Conference End
Display Mode Allows the choice of what is displayed when the conference ends.
Display either Picture-in-Picture (with the local encoder view) or a
Blank Screen.
Local Ringer IR If Enabled, the ringer may be enabled or disabled via the IR remote by
the user (operator) of this VBrick. If disabled, the local operator
cannot change the state of the ringer. It will remain as set above in
"local ringer".
Conferencing
Name Used to configure the name of the user (operator) of this VBrick. This
is the name, which will appear on the conference guide screen used to
set up the conference. The default entry is \h or \H, which identifies
the unit by the Host Name of VBrick appliance.
SAP IP Address The SAPs for Conference Call setup are sent to this destination IP
Address.
SAP Port The SAPs for Conference Call setup are sent to this destination IP/
UDP port.
SAP Retransmit
Time Allows setting the SAP retransmit time.
Note COM is dedicated to Passthrough. COM2 is a dual purpose interface. At the factory
default it can be used as a serial connection to the VBrick Command Line Interface
(CLI) tool for configuration purposes. When configured for Passthrough, the CLI
feature is used for camera control.
