3.15 Pulse
• If any of the units I/O is configured as an output, you can pulse that output one
or more times based on a specific input condition. The Pulse Width and Delay
between Pulses is selectable in milliseconds. The delay is only required when
more than one pulse is being sent.
• Select the Pulse from the Action drop-down menu and pick a desired output
channel, the Number of Pulses and the Pulse Width.
• When done, the user clicks the Add button to append the command to the
existing user string as shown in Figure 12.

3.16 I/O Control
• The I/O Control tab as shown in figure 13 allows the user to configure any or
all four discrete I/O as inputs or outputs.
• An input can be as Input-Contact, which is for normal ‘dry-contact’ type
devices or Input-Voltage which can be a DC voltage from 9-28 vDC.
• Any I/O configured as inputs may have the current status
read by clicking the I/O Status button.
• Any I/O configured as outputs may have the output state set by selecting the
appropriate control button.
• RTS is an OUTPUT, CTS is an INPUT. Action based configuration strings can
be created for the CTS Input only.
• The HR-4P unit can be assigned a unique address value from 01 to 99. This is
used as part of the “Long Command Format” mode when serially
communicating with the unit. Only the HR-4P unit with that unique address will
respond to RS232 commands. All HR-4P unit addresses receiving the serial
information must be unique otherwise incorrect operation will occur!
• All HR-4P units will respond to address 00. If multiple devices are connected
together serially, all devices will respond resulting in garbled RS232
transmissions.

o Short serial command format: ADR?
• After using the Connect button and establishing communication with a HR-4P
unit, this tab will show the units Firmware Version Number as well as its
programmed Address.
