Test
Test commands can be sent from a standard terminal with an RS-232 connection. The
terminal is connected to the master MA-43 (address 00), which is the only MA-43 that
can act on the test commands. To be able to give test commands the MA-43 has to be
in the test mode. Test mode can only be entered directly after power up or reset of the
master MA-43. To enter the test mode, send an ASCII 0 as the first character to the
master MA-43 after power up or reset. The MA-43 then answers with a character string
(***** MA-43 TEST MODE ******). During the test phase normal data traffic will be
disturbed. The MA-43 will leave testmode with a reset as soon as a start character is
sent to the master MA-43.
The following test is available:TEST1.
Test 1
The test is designed to be used to control an installation. TEST1 first resets all slaves,
then all slave addresses are polled. The slaves which recognises their own address ans-
wer with a configuration message. 10 slaves will be displayed in ascending order, the user
is asked to press a key to continue to see 10 new slaves, only the answering slaves will
be displayed. The units will answer with the information seen below. To test the RS-232
hardware the slaves have to be looped back between TD and RD (position 2 and 3 in
the 25-pole D-sub). The test can run without TD and RD looped on the slaves, but the
RS-232 interface will not be tested.
