16.3. RF service (R)X

Information from the RF receiver channel (mainly for production and debugging purposes)

type R Enter

Service RX:
RSSI constants: (a)djust de(f)ault
modem (s)tatus     RX e(y)e
fr(e)q. step  modem (R)eset

(a)djust de(f)ault — calibration setting for measuring the RSS level, for production purposes


modem (s)tatus — informations about RF channel state

RF modem status C0h
FX919 status    00h
idle errors 0  period 0 s
noise syncs 679  period 128 s
noise level -125 dBm

Rf modem status C0h — status byte


FX919 status 00h — contents of the status register in the FX919 modem IC


idle errors 0 — The main processor administers supervision over the processor in the modem IC. If the modem do not carry out the instructions, a reset is performed and this counter is incremented


period 0s — how often idle errors occur


noise sync 679 — a counter of modem false synchronisation events (to noise or interference on the RF channel)


period 128s — how often noise sync occurs


noise level -125 dBm — the average noise level on the RF channel. The first 3 ms of each received packet and the alien packets weaker then RSS treshold are included in the noise. The value is integrated in the time, the influence of disturbing signal expires after about 10 sec.


RX e(y)e — This function is used for diagnostic purposes in the modem part (in production only).


fr(e)q. step — Function used to switch channels in the set grid (25kHz). Both receiver and transmitter frequencies are changed using the (u)p or (d)own command.

Freq. (s)tep: 25 (u)p (d)own

modem (R)eset — RF modem reset performed. Any service function on the RF channel is completed by performing a reset of the RF modem.

16.4. RFservice (T)X

Services of the RF transmitter channel for production purposes.

type T Enter

Service TX:
(c)arrier (r)andom (s)ync
(dNNNNNNNN) hex data (p):5000ms
fr(e)q. step modem (R)eset

(c)arrier — Radio part transmits unmodulated carrier.


(r)andom — Continuous transmission of random data. Used in production to judge the signal with the RX eye at the receiving station.


(s)ync — Transmits the RF data frame synchronisation sequence.


(dNNNNNNNN) — Repeated transmission of four bytes. From these, each is assigned another pair of NN. This enables measurements with an arbitrary setting.

(p): 5

hex data (p): 5000ms — transmission duration, max. selectable time is 65 535 ms


fr(e)q. step — see RF service (R)X above


modem (R)eset — see RF service (R)X above

16.5. (e)cho

Toggles the keyboard echo off/on.

type e Enter


ECHO OFF now — the keyboard characters are not displayed now

To switch ECHO ON again, type e Enter here or from anywhere press Esc Enter se Enter or restart Setr.exe

local time: 2005-09-01 15:12:45 LOC — value according to menu (s)ervice (t)ime (d)ay time with suffix LOC for local time (winter) or LTS for local summer time


uptime: 537 sec — time elapsed from hw reset, see sts menu


day time:2005-09-01 13:12:45 GMT — GMT time maintained in Communication Unit, see (U)nit (e)dit


log write at 86400s — time counted from hw reset in which the next log write will occur, see (U)nit (e)dit (l)og period

The unit status would also display warnings when the CU is in some exceptional state, e.g.:


All transmitting disabled! — non standard states messages


Test active on Node 1 — message about running some of tests on the node 1

Binmon: SCC2

Binmon: SCC2 — monitoring of serial channel


remaining free space for auxiliary buffers. The table displayed shows the number of packets (buffers) waiting in different queues throughout the CU.

16.7. (t)ime

There are three sort of time used:

  • The GMT is used in the CU and is kept with a lithium battery. Effective life of the battery is minimally 15 years under normal operation. The life at disconnected supply is however 3 years only.

  • The local time valid on the CU station. This time is set by (s)ervice (t)ime. It is corrected by (U)nit (e)dit DI(F)F parameter to get the GMT, which is kept in the CU.

  • The distant operator time jis used by the operator, which can be situated in different time zone. It is obtained from GMT by subtracting of parameter -t, kwhich is found in the file Morse.par in the operator’s PC.

The local time us used in (s)ervice (t)ime menu and in transmitted old monitoring, which creates the monitoring message completely in the source node. The GMT is used in all other functions inside the CU, like saving time of logs, Events or time synchronization by (U)nit (e)dit Time sync.

The distant operator time is used for display of logs, Events and (new) Monitoring messages.

16.9. (c)lock info

The system clock frequency is measured in the course of four seconds with resolution in kHz. Caution! The CU is “dead” for these four seconds. In real operation, this action will cause an CU failure for four seconds. The signal from the on-board RTC (Real Time Clock) is used for measurement, so the accuracy of the clock value obtained cannot be better than the RTC accuracy.
