Port Settings
The serial and Ethernet communications bits are mutually exclusive.
Table 5.47 shows the debounce settings of the communications bits for serial
communications (E87CH = 2SS, 2SD, 3SM, or 3SS) and Table 5.48 shows
the debounce settings of the communications bits for Ethernet
communications (E87CH = 2E, 3E, or 4E).
e
This setting is hidden if E87CH = 2E, 3E, 4E or if E87CH = (2SS, 3SS) and 87PCH = 2.
f
This setting is hidden if E87CH = 2E, 3E, 4E or if E87CH = (2SS, 3SS) and 87PCH = 1.
g
This setting is available if Channel 1 contains a EIA-422 serial card; and E87CH = 3SM, 2E, 3E, 4E.
h
This setting is available if Channel 1 does not support the C37.94 protocol, or E87CH = 2E, 3E or 4E (forced to E).
i
This setting is available if Channel 2 does not support the C37.94 protocol, or E87CH = 2E, 3E or 4E (forced to E).
j
This setting is available only if E87CH= 2SD.
k
This setting is hidden if E87CH is not 2E, 3E, or 4E. Be sure the setting is a multicast address (high-byte must be 01).
l
Be sure to set 87LTMAC, 87LMAC1, 87LMAC2 and 87LMAC3 to unique values.
m
This setting is hidden if E87CH is not 3E or 4E. Be sure the setting is a multicast address (high-byte must be 01).
n
This setting is hidden if E87CH  4E.
o
This setting is hidden if E87CH is not 2E, 3E, or 4E.
p
This setting is hidden and forced to default if E87CH = 2E, 3E, or 4E.
