Ss
= Two ASCII characters that provide status information about the
controller hardware. The two characters represent one byte. Each
character is in the range 0 to 9 and A to F.
Table 2 defines the meaning of each bit in the status byte. Each bit
can be set to 1 or 0, where
1
= an error and
0
= no error. So a
response of:
00
= No diagnostic errors (normal response)
The RX142 running with no errors returns the following string:
<SOH>
SCR4**00
<CR>
