9.0 Testing the 7170 IP-Link Transceiver:
There are several functions of the IP-Link Transceiver that can be tested to confirm
that it is operating properly. Testing is broken up into parts with focus on
increasingly advanced functionality with each part.
A. Test Basic Board Functionality:
The tests in this part are intended to check that there is power to the boards and that
they have at least basic functionality.
Testing RF Board Local operation.
1. After performing a power up or Radio Reset the RX, WA, and AL LEDs will
come on for about one second during the self-test process.
2. Once self-test is complete, the AL LED will come on steady.
Testing Interface Board Local operation.
The board has two LEDs that indicate the status of the Ethernet link. The LNK LED
indicates the status of the Ethernet. When illuminated, the Ethernet Port is receiving
the Ethernet ‘heartbeat’ and is connected to a live network. If this LED is not
illuminated, there is a problem with the Ethernet wiring or the network. The ACT
LED indicates activity on the network. The LED will flash when a data packet is
received or transmitted.
1. If the Ethernet port your IP-Link Transceiver is correctly attached to another
functioning Ethernet port there should be activity on the LNK and/or ACT
LEDs as indicated above.
B. Test Local Board Functionality with terminal:
The tests in this part check the interaction between each board and the attached
terminal.
A terminal connected to the “Serial Input” Port is required to perform testing of the
IP-Link Transceiver at the local installed location. Instructions for connecting and
configuring a terminal to the IP-Link transceiver can be found in Section 8
“Programming and Setup of the 7170 IP-Link”.
Receiving the output on your terminal’s display as shown in “Example 1: Startup
Messages” confirms most of the basic functionality of the IP-Link Transceiver.
Being able to successfully setup the IP-Link Transceiver as discussed in Section 8
confirms functionality and interaction with all the boards.
C. Test RF Signal:
Tests in this part are intended to check the transmission line and components for
proper operation and problems. This is a very important test and should be
performed as soon after power up as feasible. Operating the unit with a faulty
transmission line or component could cause damage to electronics in the unit. As a
precaution, you could disconnect the dB9 connector from the transceiver inside the
IP-Link until this test can be performed.
