Overall percentage shows the percentage of Host received packets versus Host transmitted packets.
# of Packets to Send
Number of Packets to Send programs the number of packets the Host should send to the Remote before
stopping.
Bytes of Data / Packet
Bytes of Data / Packet is the programmable number of data bytes in each packet the Host sends. The
Remote will respond with the same number of packets.
COMPort/Network Ratio
COMPort/Network Ratio is the ratio of the COM port baud rate to network (over the air) baud rate of a
modem. This is used if the network baud rate is slower than the COM port baud rate. If the COM port
baud
rate is 9600 and the network baud rate is 4800, set the ratio to 2. If the two are the same, set this field to 1.

Packet Delay (s)
Packet Delay (s) is the number of seconds for the Host to delay between sending each packet. This field
ranges from 0.00 to 10.00 seconds (in 0.25 second intervals).
Host/Remote
Host/Remote is used to configure COM port options.
Host (Primary Port) - Configures the primary COM port as the Host device (the device initiating
packets
to the Remote device.
Remote (Primary Port) - Configures the primary COM port as the Remote device (the device
responding
to the packets from the Host device).
Host/Remote (1 computer / 2 ports) - Configures the primary COM port as the Host device and the
secondary COM port as the Remote device. This option requires a computer with 2 COM ports.
Host/Remote (1 Port using a Y-cable) - Configures the primary COM port as the Host and Remote
device.
A Y-cable is required for this option (with transmit connections split to the transmitting device and
receive
connections split to the receiving device). A computer with 1 COM port is utilized for this option

The Array Test screen is used to send programmable length test packets. Packets Tx‟ed - total number of
packets transmitted.
# of Packets to Send
# of Packets to Send allows the user to set the total number of packets to send before stopping (field range
is
0 to unlimited)
