AES 7788 Series RF Subscriber Unit ─ Installation and Operation Manual

AES Corporation 37 40-7788, Rev 6, August 30, 2016

Monitor Function output

The output from the monitor modes is somewhat cryptic. A brief over is provided

here with the suggestion that the Support Knowledgebase be visited for additional

information. First example is as viewed on an HHP which can only display two at at

time.

<ORIG #PN-> DEST FROM

-> TO <Pack ID>

ORIG is the ID that initiated or originated the Packet. PN is a sequential Packet

number between 00 and FF. DEST is the destination with 0000 indicating the Central

Receiver. FROM is the ID that has transmitted the Packet. TO is the ID that the

packet was transmitted to by the FROM. The -> represents an arrow showing the

flow or direction of the transmission. The next example as viewed on a PC Terminal.

<1234 #1A-> 0000 1234 -> FF01 <D_CHKIN>

The example above is a unit with ID of 1234 is transmitting a Check-In packet

through an ID of FF01 which is a common ID used for an IP-Link. The next line is

the Unit FF01 assumed to be an IP-Link responding with a Packet Acknowledgement.

<1234 #00-> 1234 1234 -> 1234 <P_RR>

The example above is a broadcast. All ID’s are the unit sending the broadcast

message. This particular broadcast is a Receiver Ready. These are periodically

broadcast by all units to update other units with that hear it of the latest status. This

keeps routing Tables up to date.

4.10 KEY TRANSMITTER

HandHeld Programmer: <SHIFT> + <F5> PC Terminal: <e>

This function activates the transmitter for about 5-6 seconds. This allows the installer

to use external test equipment (SWR, power meter, etc.) to test the radio power,

cables connections, antenna tuning and other radio parameters. It is assumed that the

programmer is connected to the subscriber, the transceiver is connected to the

subscriber circuit board, power is on and the antenna is connected.

To use: Push programmer keys <SHIFT>+ <F5> PC Terminal: <e>

KEYING TX..

Hold down the Shift key and then press the F5 key to activate the transmitter for 5

seconds. After the 5 seconds a TIMEOUT message will display. Press <ENTER>

before the 5 second timeout to abort in which case OK will be displayed.

Activating this function causes the transmitter to go on the air for 5 seconds, and then

shut off automatically. Press the ENTER key to cancel an active transmit test.
