4.5.3 Program Configure Audio

Audio configuration programming consists of AUX MUTING and SIDETONE MUTING. When AUX AUDIO is muted, external audio devices connected to the data port will not work. When SIDETONE AUDIO is muted, voice will not be heard in the handset earpiece while transmitting.

Refer to Table 4-4 and see Figure 4-6. Perform the following procedure to view the audio programming tree:

a. Choose PGM>CONFIG>AUDIO menu choices.

b. Use the keys to scroll through the AUX AUDIO options (UNMUTE, MUTE) and press [ENT].

c. Use the keys to scroll through the SIDETONE AUDIO options (UNMUTE, MUTE) and press [ENT].

4.5.4 Program Configure TOD

The AN/PRC-150(C) Time-of-Day ([TOD], meaning standard calendar day) is used for operation in HOP and Third Generation (3G) radio modes as well as for scheduled LQA and ALE Linking Protection.

AUX AUDIO UNMUTE

MUTE

UNMUTE: Enables audio from J3 DATA port, which is necessary when using auxiliary audio equipment interface.

MUTE: Disables audio from J3 DATA connector.

SIDETONE AUDIO UNMUTE MUTE

UNMUTE: Voice or modem audio is heard in earpiece.

MUTE: Voice or modem audio will not be heard in handset earpiece while transmitting.

NOTE: Set to MUTE when using external audio equipment to prevent feedback.

4.5.4.2 Set TOD Manually

HOP operation requires the TOD to be set to within +/- 90 seconds of actual HOP net time in order to transmit or receive TOD syncs with other radios. 3G operation requires the TOD be set to within +/- 7 minutes of the actual 3G net time, to allow the radio to receive 3G sync by means of a sync broadcast or sync request. ALE operation with Linking Protection requires the TOD to be set to within +/- 15 seconds of the actual ALE net time to allow reliable linking operation.

NOTE

It is strongly suggested that all radios maintain and use Coordinated Universal Time (UTC, GMT or Zulu) for all operations to ensure consistency between radios.

Refer to Table 4-5 and see Figure 4-7. Perform the following procedure to set AN/PRC-150(C) TOD:

a. Choose PGM>CONFIG>TOD menu choices.

b. Use the keys to select “+” or “-” offset and press [ENT].

c. Press the numeric keys to enter the correct UTC OFFSET value (if necessary) and press [ENT].

d. Press the numeric keys to enter the correct LEAP SECONDS value and press [ENT].

e. Use the keys to scroll through the DATE FORMAT options (MM-DD-YY, DD-MM-YY, YYYY-MM-DD, ZULU) and press [ENT].

f. Press the numeric keys to enter NEW DATE and press [ENT].

g. Use the keys to scroll through the TIME FORMAT (12-HR or 24-HR), and press [ENT].

h. Press the numeric keys to enter NEW TOD and press [ENT].

Menu Item Options Remarks

UTC OFFSET +00:00 Offsets the radio’s time from GMT/ZULU time.

LEAP SECONDS 00 - 99 seconds Adjusts the radio’s time for leap seconds (difference between GPS time and UTC time).

DATE FORMAT MM-DD-YY

DD-MM-YY YYYY-MM-DD ZULU

Set the preferred date format.

NEW DATE MM-DD-YY Set the date. The display and date entry varies based on the DATE FORMAT selected.

TIME FORMAT 12-HR 24-HR

Configure the format that the radio uses to display time of day. Not available in Zulu.

NEW TOD XX:XX:XX Set the Time-of-Day. TOD is not available in Zulu.

NOTE

If a PLGR is attached and is operational, it may automatically acquire the proper time as the user is entering the date or time.

If the GPS acquires the satellites while the time is being manually entered, then after the users presses the [ENT] key, the display will show ERROR: TIME SETTING

CONTROLLED BY GPS for several seconds. If it acquires while the date is being entered, the display will show

ERROR: DATE SETTING CONTROLLED BY GPS for several seconds.

4.5.5 Program Configure Message (Routing Incoming Data)

This procedure is used to specify the destination to which incoming data is to be routed. Refer to Table 4-6 and see Figure 4-8. Perform the following procedure to specify the incoming data routing location:

a. Choose PGM>CONFIG>MESSAGE menu choices.

b. Use the keys to scroll through the ROUTE MODEM DATA TO options (DTE PORT, RDP, FILE) and press [ENT].

c. Use the keys to scroll through the ROUTE ARQ DATA TO options, (DTE PORT, RDP, FILE) and press [ENT].

d. Enter source address of message and press [ENT]. The DESTINATION ADDRESS entry screen appears.

e. Enter the destination address of the message and press [ENT].

f. Use the keys to scroll through the AUTO TX TYPE options (ARQ, NON-ARQ) and press Figure 4-7. PGM>Config>TOD Menu

DTE PORT - located on the AN/PRC-150(C)’s front panel J3 DATA connector. This port is used to pass data between the AN/PRC-150(C) and a data terminal using an RS-232 serial data connection.

RDP - located on the AN/PRC-150(C)’s front panel J3 DATA connector. This port is used to pass data between the AN/PRC-150(C) and a Harris data terminal, such as the Harris WMT or TacChat. Uses asynchronous PPP connection at 19.2 kbps to 115.2 kbps. PPP port speed should be set to the same speed for all radios on the net to avoid interface problems.

FILE - a file in the AN/PRC-150(C)’s internal file system. An external device must be used to access the files. The data stored in the AN/PRC-150(C) is lost when the radio is powered OFF.
