22. Channel send

This diagnostic function resembles the Send packet test. Nevertheless it is not a test and it does not deal with packets. It works with the physical layer of communication through the SCC I/O interface. Arbitrarily created data frames can be sent out from that interface, or forced to be received. Forced data transmissions from inner SCP port can be initiated, too.

From MORSE main menu type i n Enter

Channel data send.
(d)estination: SCC0-TX
d(a)ta :abcdef
(r)epeat period :2000ms
(s)tart sto(p)

type d Enter

Meaning of items:

(d)estination: SCC0-TX

— interface and direction of the data frame SCC0-TX sending

(1) SCC0-TX
(2) SCC1-TX
(3) SCC2-TX
(4) SCC3-TX
(a) SCC0-RX
(b) SCC1-RX
(c) SCC2-RX
(d) SCC3-RX
(0) SCP port
d(a)ta: abcdef

— assigning of sent data (abcdef), see Section 21.1, “STATISTIC TEST”

type a Enter

    /0 /1 /2 /3 /4 /5 /6 /7 /8 /9 /A /B /C /D /E /F  ASCII:
    61 62 63 64 65 66                                abcdef

   Data: (a) ASCII (h)ex (r)andom (c)lear

Data frame definition is done in standard data editor, see Section 21.1, “STATISTIC TEST” description for details on page.

(r)epeat period: 2000ms

— repeat period of data frame transmissions. When zero value is configured, a single transmission occurs immediately after the (s)tart command is issued


— starts sending


— stops sending

22.1. Enable RF(T)X

This function is used to disable or enable transmitting of the RF part of the CU. It influences the actual (RAM) value of the RFTX disable switch in RF modem parameters.

From MORSE main menu type i T Enter

RF packet transmitting:
(d)isable  (e)nable

type d Enter

TX disable
Are you sure? (Y/N)

press Enter

(T)X off

— state of CU

The current state of RFTX disable parameter can be found by query (s)ervice unit (s)tatus, where the message All transmitting disabled! appears in case of disabled transmitting. If this message is missing then the transmitting is allowed.
