Chapter 2 - Connections
Do not make any connections to the 232DRIO until you have
read this chapter. Remember to power down the unit and any
other connected devices before making any kinds of connections.
Also be sure that the wires connected to the terminal blocks will
support the voltage and current requirements of your external
devices.
This chapter will cover the connections for the 232DRIO. There
are four sets of connections: opto-isolated input (optional), relay
outputs, serial port, and power supply.
I/O Connections
Connections to the I/O lines are made through the internal block
terminals. These should clearly be labeled on the board. Refer to
Table 2.1. See Chapter 5 for I/O interfacing examples.
Opto-isolated Input (black terminal blocks)
The non-polarized, opto-isolated input line is CMOS/TTL
compatible and can handle voltages from 0Vdc/Vac to +30Vdc/Vac.
Refer to the Specification for a complete detail.
Relay Outputs (blue terminal blocks)
The relay output lines have a maximum operating voltage of
+250Vac/+125Vdc and are CMOS/TTL compatible. Refer to the
Specification for a complete detail. Both relays are de-energized
at factory default settings.
Ground
Connect the ground correspondingly as marked. Do not
interchange the grounds for input and power. Otherwise, the input
will not be optically isolated. The input is non-polarized so the input
ground could be connected to either one of the black terminal while
the power ground must be connected as marked on the blue
terminal.

Command: !0S
Argument: {…} (shown in bold face)
Response: none
ASCII Example: !0S<ETX>
Dec. Example: !0S<3>
Hex. Example: !0S<03>
Bin. Example: !0S<00000011>
Description: Relay #2 is energized (“1”), and Relay #1 is
energized (“1”).
Command: #0S
Argument: {…}{~…} (shown in bold face)
Response: none
ASCII Example: #0S<ETX><n>
Dec. Example: #0S<3><252>
Hex. Example: #0S<03><FC>
Bin. Example: #0S<00000011><11111100>
Description: Relay #2 is energized (“1”), and Relay #1 is
energized (“1”). Note that the complement is
returned immediately following the data byte.
NOTE: If any of these lines are defined as inputs the bit settings are
ignored. Since Bit 2 is defined as Input #1 the bit setting is ignored.
Two important ideas to keep in mind when sending commands
back to back or in sequence are the following:
1)If the “!0R” is sent, one character delay must follow immediately
before any other commands are sent.
2)If the “#0R” is sent, two character delay must follow immediately
before any other commands are sent.
For example: 1) “!0R_!0S1”
2) “#0R_ _ #0S1”
Otherwise, the microcontroller will miss the second “!” or “#” and not
interpret the second command at all since it is still trying to transmit
the returned data byte(s) to the user.
