1.2.5 Select Units to change the Auto Step x
simulation units.
1.2.6 Select Low pt to enter the beginning test point
value.
1.2.7 Select Upr pt to enter the ending test point
value.
1.2.8 Select Steps to enter the number of test points
in the procedure including the Upr pt. The Low
pt to Upr pt range will be evenly divide
according to the number of steps selected.
1.2.9 Select Dwell Time to choose the duration of
each simulated point or choose Manual for the
manual advance option.
1.2.10 Auto Ramp 1-3 menu options allow pre-
programmed Simulations to be set up and
executed automatically for those applications
requiring an automatic incremental advance from
Low pt to Upr pt and down again. User
selects a start delay time, a ramp cycle time, direction (up scale, up scale/down scale). Up to
three (3) Auto-Ramp settings are remembered and stored for future use.

Connectors and Wiring Configurations
The module has a 6 pin male connector that plugs into a 6 pin female connector of the Measure cable (by
manufacturer).
Pt 100 RTDs are available complete with plug connector, Rs resistor, and 5 foot coiled cable.
RIO4000 Plug Connector
The connector is wired to RTDs for measurement applications using a dedicated RTD probe.
P/N A900442-00026 as shown above is the “connector only” and can be used to create a customized RTD
connection to the RIO4000 module.
Pins 1 and 2 of the 6 pin connector are utilized for identification of RTD Types. A resistor value (Rs) has
been assigned to each of the twenty-two (22) RTD Types supported (see Table 1 below for Rs values).
The connector pin-outs are as follows:
PINS Functions
1, 2
Rs – Probe ID Resistor (see Table below)
3, 4
One side of RTD
5, 6
Other side of RTD
Pins 3 and 6 must be connected. See RTD wiring configuration options later in this document for more
detail.
