of Figure 6 must be applied. The threshold of
the V.35 receiver is ±200mV. The V.35 receiv-
ers can operate up to 5Mbps. All of the differen-
tial receivers can receive data up to 5Mbps.
Decoder
The SP503 has the ability to change the inter-
face mode of the drivers or receivers via an 8–
bit switch. The decoder for the drivers and
receivers is not latched; it is merely a combina-
tional logic switch. The codes shown in Tables
1 and 2 are the only specified, valid modes for
the SP503. Undefined codes may represent other
interface modes not specified or random out-
puts (consult the factory for more information).
The drivers are controlled with the data bits
labeled TDEC
3–TDEC0. The drivers can be put
into tri-state mode by writing 0000 to the driver
decode switch. The receivers are controlled
with data bits RDEC
3–RDEC0; the code 0000
written to the receivers will place the outputs in
an undetermined state. All receivers, with the
exception of SCT, do not have tri-state capabil-
ity; the outputs will either be HIGH or
LOWdepending upon the state of the receiver
input.
