Passthrough Mode
In this mode, data received by a device ‘input’ is transmitted using TCP/IP over the network and then
converted back to serial data by a device ‘output’. Data flow is fully bi-directional and totally
independent of whether a VN-MATRIX is configured as an encoder or decoder.
One device within a passthrough group is designated as a server. One or more devices are then
‘connected’ as clients (in passthrough mode):
Serial ports on each VN-MATRIX need not share a common baud rate. However, where a large
amount of data is sent from a high speed to a low speed data link, some form of handshaking/flow
control may be required to prevent buffer overflow on the output device. Standard flow control
methods are fully supported.
Any number of serial passthrough groups may exist on the same network.
To set up a serial passthrough group, see page 91.
