3-12 PROGRAMMING AND DIAGNOSTICS MDS 05-2415A01, Rev. A
Table 3-2. Programming and Test Commands—Part 2 of 3
DIAGNOSTIC AND TEST MODES
TEST MODES
KEY ......... Keys the transmitter
(Transmit modulation enabled)
DKEY....... Dekeys the transmitter
TEST_1 ... Keys the transmitter and enables a constant
DTMF Loopback test tone. Useful for checking
the radio’s
diagnostic
deviation level
TEST_2 ... Disables DTMF Loopback test tone and
unkeys the transmitter.
TEST_5 .... Disables VCO
TEST_6 .... Enables VCO
TEST_7 .... Turns on modem test tones and keys the
transmitter for 12 seconds.
• With 4800/9600 bps modem: Sinewave at
1/2 data rate.
• With 1200 bps modem: 1200/2200 Hz tone.
DIAGNOSTIC MODES
MODE_1 .......... Enable-Standard Diagnostics
MODE_2 .......... Enable-Advanced Diagnostics
MODE_3_xxxx . Enable Remote Maintenance
Functions (xxxx is the data rate in bps)
NOTES– Remote Maintenance Module (03-1958A01)
must be installed to invoke these functions.
4-wire radios in Mode 3 must use 1200 as the
modem data rate.
DIAGNOSTIC CALIBRATION
These commands are used with calibrated test equipment attached to radio.
CPWR . Calibrate forward power to 5 Watts for diagnostics
RSSL... Calibrate RSSI at –110 dBm
RSSH... Calibrate RSSI at –70 dBm
SET/PROGRAM COMMANDS
OPERATING PARAMETERS
PASS_xxxx ...... Password Entry
PTX_xxx.xxxx... Program transmit frequency†
PRX_xxx.xxxx .. Program receive frequency†
PLBC_xxxx....... Program loopback code (0000–9999)
ESTE................ Enable Squelch Tail Eliminator
PCTS_xxx ....... Program CTS Delay in ms; 2-255 ms, no
leading zeros (1–3 digits)
PSCD_xxx ....... Program soft carrier dekey; 2–255 ms,
no leading zeros (1–3 digits)
ETOT .............. Enable Time-out Timer
DTOT .............. Disable Time-out Timer
PTOT_xxx........ Program Time-out timer (sec)
(1–3 digits)
PPTT_xx .......... Program Push-to-talk delay (0-31 ms)
† A move of more than 6 MHz requires re-alignment of the transceiver’s tuned circuits. Consult factory for details.
POWER, FREQUENCY AND DEVIATION
A Remote Maintenance Module (P/N 03-1958A01) must be installed in the transceiver and the transceiver must be set to
Mode 3 Diagnostic for these commands to have any effect. Electronic controls (EEPOTs) for these parameters are
incremented or decremented as a percentage of their maximum value—zero to 100 percent. Changes in these settings
are not permanent until the RMST command is sent.
GENERAL:
RMRD .............. Read present EEPOT settings
RMIST .............. Store present EEPOT settings
RMIS ................ Reset all EEPOTs to 50% and store
settings
RMOV .............. Restore all EEPOT to the previously
stored settings to 50%.
<SPACE> ........ Repeat last adjustment command
FREQUENCY:
IF ...................... Increment Frequency by 1
DF .................... Decrement Frequency by 1
INCF_xx ........... Increment Frequency by xx value
DECF_xx .......... Decrement Frequency by xx value
PRIMARY MODULATION:
ID ..................... Increment Deviation by 1
DD .................... Decrement Deviation by 1
INCD_xx........... Increment Deviation by xx value
DECD_xx ......... Decrement Deviation by xx value
POWER:
IP ..................... Increment Power by 1
DP .................... Decrement Power by 1
INCP_xx ........... Increment Power by xx value
DECP_xx ......... Decrement Power by xx value
OWNER’S INFORMATION
POWN_xxxxx ....... Program owner’s name
(20 characters maximum)
POWM_xxxxx....... Program owner’s message
(27 characters maximum)
