Remote to Host % shows the percentage of data packets the Remote device successfully sent to the Host.
Overall %
Overall % shows the percentage of Host received packets versus Host transmitted packets.
# of Packets to Send
# of Packets to Send is a programmable number to tell the Host how many data packets to send to the Remote. After the
programmed number of data packets are sent, the transmission will automatically stop.
Bytes of Data/Packet
Bytes of Data/Packet is a programmable number to tell the Host the number of data bytes to send in each packet. The
Remote will respond with the same number of data bytes received.
COM Port/ Network Radio
Com Port/Network Radio is the ratio of COM Port baud rate to network (over-the-air) baud rate of the 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 COM Port baud rate and the Network Baud Rate are the same, set the Ratio to 1.
Packet Delay (s)
Packet Delay (s) tells the Host the number of seconds to delay between sending each data packet (range is from 0.00 to
10.00 seconds in 0.25 second intervals).
Host/Remote
Host/Remote allows the user to choose the COM Port configuration.
Host (Primary Port) - Configure the Primary COM Port as the Host device (the device initiating packets to the Remote
device).
Remote (Primary Port) - Configure the Primary COM Port as the Remote device (the device responding to the packets from
the Host device.
Host/Remote (1 computer / 2 ports) - Configure the Primary COM Port as the Host device and the Secondary COM Port as
the Remote device. A computer with 2 COM Ports is required for this option.
Host/Remote (1 Port using a Y-cable) - A computer with 1 COM Port is typical for this option (See Table 9). Configure the
Primary COM Port as the Host and Remote device. A Y-cable is required for this option (where Tx connections are split out
to the transmitting device and the Rx connections are split out to the receiving device).
