Paired Mode 
Paired Mode (also called Serial Tunneling or Serial Bridge mode) allows 
serial devices connected to two PES1A/PESV1A converters to communicate 
across  a  network.  The  two  PES1A/PESV1A  converters  automatically 
connect to each other. 
In Paired Mode the heartbeat feature ensures reliable communications by 
restoring the connection if communications are temporarily lost at either end 
due to loss of power or Ethernet connection. 
Other Communications Modes 
PES1A/PESV1A  Converters  also  feature  the  following  communications 
profiles: 
Terminal Mode allows you to connect a PC running terminal software to the 
PES1A/PESV1A serial port and communicate with the PES1A/PESV1A via 
a command line interface.  
Modem Emulation Mode allows you to configure the serial port to operate 
as if it is a modem. For legacy applications where a serial device is set up to 
communicate through a modem, the serial device can now be connected to 
the  PES1A/PESV1A  and  communication  occurs  over  the  network.  The 
PES1A/PESV1A emulates modem responses to and from the serial device. 
In Console Management Mode the PES1A/PESV1A can be configured for 
connection to the management port typically found on network devices such 
as routers, switches and servers. This allows  remote management of  the 
network  device.  Communication  can  be  accomplished  using  telnet  to  a 
specific port in the converter. 
Custom Mode  allows you to custom configure the PES1A/PESV1A serial 
port  and  is used  if your  application  does not  fit into  any other  predefined 
modes.
