 “Reset Watt-Hour Counters” (9) resets the incremental Watt-hour values including the

corresponding accumulated Watt-hour minutes.

 “COM1 Baud” (10) provides selection of the baud rate for COM1 which is connected to the WiFi

and/or Ethernet module. The baud rate is selected then the “Go” button must be clicked.

“19200” baud is required for firmware upgrades otherwise “115200” baud is recommended

 “Packet Chunk Size” (11) is the maximum number of bytes buffered before a chunk of data is

sent during packet send or web interface communication. It is recommended to keep this value

set to “2047”. Never use a value greater than 2047.

 “Packet Chunk Interval Time” (12) is the amount of pause time between chunks of data. This

provides time for some communication modules to process a chunk of data before sending it

another chunk. The recommended value is between 200 and 800 unless specified differently for

a given module. Each unit represents several microseconds

 “Calendar Time and Date” (13) sets the system time. Clicking “Get Local Date” reads the

computer time and “Get UTC Date” reads the “Coordinated Universal Time” (UTC) which is the

primary time standard by which the world regulates clocks and time. Once one of the two time

option is selected, it can be saved to the GEM by clicking the “Save Date to GEM”

 “Keep Alive String” (14) is a one to eight character string which is sent when real-time packet

send is turned “off”. See Real-Time ON-OFF on page 22

 “Keep Alive Pulse” (15) provides a means of disabling the keep-alive function. If disabled, there

will be no data communicated if Real-Time Packet send is set to “Off”. Care must be taken not to

disable this if the GEM is setup as a TCP/IP client since the connection to the server may be lost

permanently.

 “Reset Wh on Post” (16) works in conjunction with posting HTTP data to some sites such as

“Smart Energy Groups”. When this is enabled, the accumulated watt-hour value is reset to zero

after every packet send. This causes the watt-hour value to represent the number of watt-hours

used since last packet send. If disabled, the packet will contain an incremental value or watt-

seconds since the last time it was manually reset or the counter has wrapped around.

 “Watt-Hour Decimal/Integer” (17) If decimal is selected, the watt-hour value sent during a post

will have a value up to two decimal places. “Decimal” option is recommended. Example:

o Decimal: 23.35 watt-hour

o Integer: 23 watt-hour

ADVANCED COMMANDS BLOCK 2

Figure 34Figure 35 shows the second block of advanced commands. Each is described below.

 “Disable Chan 33-48 Post” (20) is no longer used

 “COP Test” (21). It is recommended not to use this test. This command puts the GEM in an

endless firmware loop for test purposes.

 “COM1 Flow” (22) enables/disables hardware flow control for the COM1 serial port. This should

be enabled for the following communication options: “WiFi Only” and “WiFi/Ethernet Combo”

1 2 ... 27 28 29 30 31 32 33 34 35 36 37 ... 42 43
