Swap COM Ports
Swap COM Ports allows the user to swap the Primary and Secondary COM ports. For example, if the Primary is
COM1 and the Secondary is COM2, the Primary becomes COM2 and the Secondary becomes COM1 after a Swap
COM Ports is issued. This utility is useful when more than one JSLM
2
is connected to a PC since the programming
screens all use the Primary COM port. By issuing a Swap COM Ports, the JSLM
2
connected to the second COM
port can be programmed without switching cables.
3.2.6 PORT STATISTICS
The Port Statistics utility shows some of the statistics of the PC’s serial COM ports (Primary and Secondary). (A
check in the check box indicates an active state).No entry is allowed in these fields.
