Epson MFJ-1278B manual MAXSum nn Mode Pactor Default, MAXUp nnn Mode Pactor Default

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

MAXSum nn Mode: Pactor Default: 30

Parameters:

nnn: 5<=nnn<=120

MAXSum specifies the number of cycles of error-laden information packets received that are accumulated in the Digital Memory ARQ sum buffer for reconstruction. When MAXSUM consecutive information receive errors occur, on the next receive cycle the sum buffers are re-initialized to inhibit the corruption of real-time reception by historical receive errors.

MAXUp nnn Mode: Pactor Default: 10

Parameters:

nnn: 2<=nnn<=48

MAXUp specifies how many consecutive good receptions of 100 baud information packets are required prior to the MFJ-1278B requests a SPEEDUP to 200 baud. Note that if NO200 is set to ON then a SPEEDUP will not occur because the MFJ-1278B will never request a SPEEDUP regardless of the MAXUP value. The MAXUP value should be small enough to enable timely SPEEDUP in relatively good conditions, while being large enough to avoid pointless speedups during bad conditions.

MBEGIN cccc Mode: AMTOR Default: <<>>

The MBEGIN parameter, which can be up to 15 characters long, is effective when MATCH is ON and a mode B signal is being received. When MATCH is ON, the MFJ-1278B will not print a mode B transmission until the string in MBEGIN is matched.
