The Packet Test window is used to simulate a Host/Remote polling environment. The Master unit will send out a packet

to the Remote and the Remote will reply to the Master with the same packet information. This is a useful utility for

testing modem communication.

Host Packets Tx’ed

Shows the number of data packets the Master has sent to the Remote.

Remote Packets Rx’ed

Shows the number of data packets the Remote device has received from the Master.

Host to Remote %

Shows the percentage of packets the Host device has successfully sent to the Remote.

Remote Packets Tx’ed

Shows the number of data packets that the Remote device has returned to the Host.

Host Packets Rx’ed

Shows the number of data packets the Host device has received from the Remote.

Remote to Host %

Shows the number of packets the Remote device successfully sent to the Host.

Overall %

Shows the percentage of Host received packets versus Host transmitted packets.

# of Packets to Send

Programs the number of packets the Host should send to the Remote before stopping.

Bytes of Data / Packet

The programmable number of data bytes in each packet the Host sends. The Remote will respond with the same

number of packets.

COM Port/Network Ratio

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)

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

This 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.
