SmartPAC 2 with WPC 2000 Integration User Manual 1128600
Initialization Mode 4-63
In the “combined” view, Transmit and Receive data are shown together (see the left panel in
Figure 4-42), Transmit data being displayed as blue on a white background, Receive data
displayed as white on blue. This view shows the data as it is transmitted and received in real
time. Press
F3 (Reset Buffer) to view the data starting at the beginning of the buffer.
In the “split” view, Transmit data is shown in the upper half of the screen, Receive data in the
lower half (see right panel in Figure 4-42). In this view, the data is always shown starting at
the beginning of the buffer.
Normal communications between SmartPAC 2 and the selected module (e.g., SFI) is
indicated by both Transmit and Receive data being displayed on the screen. If you want to
examine transmitted or received data, press
F2 (Stop/Start Buffer). If no data or only partial
data is displayed, SmartPAC 2 and the other module are not communicating properly.
If the Transmit and Receive Data screen indicates a communications problem, you can
perform a “loopback test.” To do so, you connect (or jumper) the TXD (transmit) and RXD
(receive) lines, and then press
F1 (Send Loopback Message) to check communications. In
effect, you are “receiving” the communications data that you are transmitting. This test is
useful when verifying the accuracy of Transmit and Receive hardware and wiring.
To perform a loopback test, follow these steps:
1.
Wire loopback jumpers for the port or ports you want to check, following the wiring
diagram in Figure 12 at the end of the manual. Figure 12 shows loopback test wiring for
both RS232 and RS485 communications. Be sure to follow the correct diagram for your
system.
2.
Select the port/module you want to test, such as “PORT 1 (SFI).” The Transmit and
Receive Data screen for that port displays.
3.
Press F1 (Send Loopback Message) to start the test. The message “LOOP BACK
MESSAGE PORT X” displays, where “x” is the number of the port you selected.
If you need help performing the loopback test, contact Wintriss Tech. Support. Be prepared to
provide the following information:
product name (e.g., SmartPAC 2 standard); installed
options (e.g., DiProPAC, ProCamPAC, etc.); and firmware version number (e.g., Vs. 2.00).
You can determine the last two items by accessing the Installed Options screen (see
Figure 4-4, page 4-9).
