PV1 SLOT
485TDCSDI only
0 to 16
0=No Connection
LOOP 1 PROCESS VARIABLE (PV) POINT ADDRESS
— Select the RS485 slot that corresponds to the TDC SDI
IOP point that will be used to access UDC Loop 1 Process
Variable (PV) data.
Recommended 485TDCSDI slots:
FTA1 = SDI/IOP POINT 1 TO 8
FTA2 = SDI/IOP POINT 9 TO 16
This will map the UDC 485 slots directly to the IOP point
numbers.
Do not mix higher slots (9 to 16) with lower slots (1 to 8) on
UDCs that will be connected to a single FTA.
OP1 SLOT
485TDCSDI only
0 to 16
0=No Connection
LOOP 1 OUTPUT (OP) POINT ADDRESS — Select the
RS485 slot that corresponds to the TDC SDI IOP point that
will be used to access UDC Loop 1 Output (OP) data.
Recommended 485TDCSDI slots:
FTA1 = SDI/IOP POINT 1 TO 8
FTA2 = SDI/IOP POINT 9 TO 16
This will map the UDC 485 slots directly to the IOP point
numbers.
Do not mix higher slots (9 to 16) with lower slots (1 to 8) on
UDCs that will be connected to a single FTA.
PV2 SLOT
485TDCSDI only
0 to16
0=No Connection
LOOP 2 PROCESS VARIABLE (PV) POINT ADDRESS
— Select the 485TDCSDI address that corresponds to the
TDC SDI IOP point that will be used to access UDC Loop
2 Process Variable (PV) data.
See “PV1 SLOT”.
OP2 SLOT
485TDCSDI only
0 to 16
0=No Connection
LOOP 1 OUTPUT (OP) POINT ADDRESS — Select the
485TDCSDI address that corresponds to the TDC SDI IOP
point that will be used to access UDC Loop 2 Output (OP)
data.
See “OP1 SLOT”.
PARITY
485ASCII only
ODD
EVEN
PARITY pertains to the use of a self-checking code
employing binary digits in which the total number of ONE's
(or ZERO's) in each permissible code expression is either
ODD or EVEN.
ODD PARITY

BAUD RATE is the transmission speed in bits per second.
300 BAUD
600 BAUD
1200 BAUD
2400 BAUD
4800 BAUD
9600 BAUD

NOTE: If you make a change in Baud Rate, cycle the power
supply after you make the change.
