•

Frame size

- ASCII communication: max. 128 bytes

- Hex communication: max. 256 bytes

•

Flag (_RCV [n]: n is a frame list no.)

It is a flag to indicate whether a user-defined frame is received in the order set by the user.

It is a BOOL type and ARRAY type in the size of 16.

If the received frame is matched with the declared frame in frame list number 3, _RCV [3] starts blinking.

→

Channel 0 : _RCV[n] (n: frame list number)

Channel 1 : _RCV1_422[n] (n: frame list number)

•

When frame receiving is done, GM7U main unit check if there’s any match between the received frame and the

declared frame in frame list. If there is, let the Link relay L(n) flag blink and save the received data in the assigned

area.

Example) When frame is set as below, the result of calculation is as follow.
