6.27 Testing The Communications Line
Once a chassis is activated by a terminal, the user may test the quality of the communications
line transmission by sending a message (test data) or random character string to the selected
chassis. The test data string must include an echo command flag before sending the LF
termination character. All character strings entered containing a “$” sign character and
terminated with a LF, are returned to the issuing terminal. Because the selected PS chassis does
not act upon data received until a GO command is recognized, no error is indicated. If a GO
command is executed and the data previously sent to the chassis is invalid, the CM responds
with an error message.
If the test data contains a “#” character, an error message is immediately returned to the
originating remote control device.
