6 IQ plus 710 Installation Manual
2.3.2 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 and
20 mA current loop receive 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.
T h e E D P p o r t s u p p o r t s R S - 2 3 2 o r R S - 4 8 5
communications; the printer port provides active 20
mA output and RS-232 transmission. Both ports are
configured using the SERIAL menu. See Section 3.0
on page 13 for configuration information.
2.3.3 Digital I/O
Digital inputs can be set to provide several indicator
functions, including all keypad functions. The inputs
are active (on) with low voltage (0 VDC) and can be
driven by TTL or 5V logic without additional
hardware. Use the DIG IN menu to configure the
digital inputs.
Digital outputs are typically used to drive relays that
control other equipment. 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 SETPNTS menu to configure
digital outputs.
Table 2-3 shows the pin assignments for connectors J7
and J8.
2.3.4 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.
2.4 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 2-1 on page 5 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 69 for analog output
calibration procedures.
