Serial Communications

To attach serial communications cables, remove
connector J4 or J12 from the board. Connector J4
provides connections for the EDP (Electronic Data
Processing) port, printer port, and 20 mA current loop
transmit signals; connector J12 provides RS-485
signals. Table 2-2 shows the pin assignments for
connectors J12 and J4.
Once cables are attached, reconnect J12 or J4 to the
header on the board. Use cable ties to secure serial
cables to the inside of the enclosure.

communications; the printer port provides active 20
mA output and full-duplex RS-232 communications.
Both ports are configured using the SERIAL menu.
See Section 3.0 on page 14 for configuration
information.

Digital I/O

Digital inputs can be set to provide many indicator
functions, including all keypad functions. Digital
inputs are active (on) with low voltage (0 VDC),
inactive (off) at 5 VDC. Use the DIG IN menu to
configure the digital inputs.
Digital outputs are typically used to control relays that
drive other equipment. Outputs are designed to sink,
rather than source, switching current. Each output is a
normally open collector circuit, capable of sinking
250 mA when active. Digital outputs are wired to
switch relays when the digital output is active (low, 0
VDC) with reference to a 5 VDC supply.

Up to eight relays can be mounted inside the flat front
enclosure; up to four relays can be mounted inside the
sloped front enclosure. Use the SETPTS menu to
configure digital outputs.

Analog Output

If the optional analog output module is installed,
attach the output cable to connector J1 on the analog
output board. Table 2-4 lists the analog output pin
assignments.
Use the ALGOUT menu to configure and calibrate the
analog output module when cabling is complete. See
Section 2.4 for information about installing the analog
output module.

Analog Output Module Installation

To install or replace the analog output module, follow
the steps listed in Section 2.2 on page 4 for opening
the IQ plus 710 enclosure.
Mount the analog output module on its standoffs in
the location shown in Figure 2-4 on page 6 and plug
the module input into connector J5 on the IQ plus 710
board. Connect the output cable to the analog output
module as shown in Table 2-4, then reassemble the
enclosure (Section 2.5).
See Section 10.7 on page 71 for analog output
calibration procedures.
