The 720i can be loaded with either PCE software or 720i batching software. Refer to Section 9.0 on page 69 or Section 10.0 on
page 83 for further information on each of these software choices.
1.2.1 Onboard Features
Features of the basic 720i include:
• Support for a single A/D or serial scale input
• Eight digital I/O channels on main board, each configurable as an input or an output
• Two serial ports on main board support duplex RS-232 up to 115200 bps. Port 2 supports RS-232 with hardware
handshaking; Port 4 supports RS-232 and 20mA communications
• Available in 115 VAC and 230 VAC North American and European versions
• Configurable print formats can be defined for up to 1000 characters each using serial commands or Revolution III. These
formats are used to print gross or net weights, truck in/out weights, accumulator weights, alert messages and header
information. Additional print formats can be created using 20 auxiliary print formats.
• Seven truck modes to store and recall weights for gross, tare and net printing. The truck register contains fields for ID
number, weight and the transaction time and date. Weights can be stored permanently or erased at the end of the
transaction.
1.2.2 Option Cards
The CPU board provides one slot for installing other option cards. Available option cards include:
• Analog output card for 0–10 VDC or 0–20 mA tracking of gross or net weight values

4. If using a 6-wire load cell cable (with sense wires), remove jumpers JP1 and JP2 before reinstalling connector J1. For
4-wire installation, leave jumpers JP1 and JP2 on.
5. When connections are complete, reinstall the load cell connector on the CPU board header and use two cable ties to
secure the load cell cable to the inside of the enclosure.
3.3.2 Serial Communications
Communications ports on the 720i CPU board support PS/2-type remote keyboard, full duplex RS-232 and 20 mA output
communications at up to 115200 bps. Optional communications cards support USB, Ethernet and fiber-optic connections to the
720i.
1. To attach serial communications cables, route the cable through the cord grip and ground the shield wire as described
in Section 3.6 on page 11.
2. Remove the serial connector from the CPU board and wire to the connector.
3. Once cables are attached, plug the connector into the header on the board.
4. Use cable ties to secure serial cables to the inside of the enclosure.
Port 1 supports remote keyboard attachment of PS/2-type personal computer keyboards (see Section 12.9 on page 112 for
information about the PS/2 keyboard interface). Port 3 uses connector J4 to provide a dedicated display port for both universal
and panel mount versions.
Serial ports are configured using the Serial menu. See Section 4.2.2 on page 36 for configuration information.

An optional dual-channel serial communications expansion card, PN 67604, is also available. The serial expansion card
provides two additional serial ports, assigned as port numbers 7 and 8. One port on the serial expansion card supports four-
wire RS-485 communications. Both ports on the expansion card can support RS-232 or 20mA connections.
Installation of option cards in connector J11 requires removal of the PORT2/OPTI port selection jumper (see Figure 3-
2 on page 10). Install the jumper to enable RS-232 communications through connector J2; remove the jumper to
enable a USB, fiber-optic or Ethernet option card installed in connector J11.
See the communications interface card installation instructions for more information.
3.3.3 Digital I/O
Digital inputs can be set to provide many indicator functions, including all keypad functions. Digital inputs are active low (0
VDC), inactive high (5 VDC).
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 24 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.
Table 3-3 shows the pin assignments for connector J6.
Digital inputs and outputs are configured using the DIG I/O menu. See Section 4.2.5 on page 46 for configuration information.
An optional 24-channel digital I/O expansion card, PN 67601, is available for applications requiring more digital I/O channels.
A digital I/O point can be configured to count active pulse inputs by setting the bit to Input (DIG I/O menu) and using
PCEE to monitor the bit. However, the fastest pulse rate that can be counted using a digital input is 10Hz (10 pulses
per second).
3.3.4 Detached Display Module (DDM)
Table 3-4 shows the connections between connector J4 on the 720i CPU board and connector J3 (Com 1) on the detached
display module (DDM) board. See board diagrams in Figures 3-2 and 3-3 on page 11.

3.4 Installing Option Cards
Each option card is shipped with installation instructions specific to that card. Use the following general procedure for all option
cards.
Disconnect power to the 720i before installing option cards. Option cards are not hot-swappable.
1. Disconnect power to the indicator. Remove backplate as described in Section 3.2 on page 7.
2. Carefully align the option card connector with connector J12 or J11 on the CPU board (see Figure 3-2 on page 10).
3. Press down to seat the option card in the CPU board connector.
4. Use the screws provided in the option kit to secure the other end of the option card to the threaded standoffs on the
CPU board (see Figure 3-2).
5. Make connections to the option card as required.
6. Use cable ties to secure loose cables inside the enclosure.
7. When installation is complete, reassemble the enclosure as described in Section 3.7 on page 12.
The 720i automatically recognizes all installed option cards when the unit is powered on. No hardware-specific configuration is
required to identify the newly installed card to the system.

Stripping Cables
Foil Insulated Cable
Figure 3-4. Foil Insulated Cable
1. Strip the insulation and foil from the cable 1/2'' (15 mm) past the grounding clamp.
2. Fold the foil shield back on the cable where the cable passes through the clamp.
3. Ensure the silver (conductive) side of the foil is turned outward for contact with the grounding clamp.
Braided Shielding
Figure 3-5. Braided Insulated Cable
1. Strip the insulation and braided shield from a point just past the grounding clamp.
2. Strip another 1/2'' (15 mm) of the insulation to expose the braid where the cable passes through the clamp.
Load Cell Cable
Cut the shield wire just past the grounding clamp. Shield wire function is provided by contact between the cable shield and the
grounding clamp.
3.7 Enclosure Reassembly
Once cabling is complete, position the backplate over the enclosure and reinstall the backplate screws. Use the torque pattern
shown in Figure 3-6 to prevent distorting the backplate gasket. Torque screws to 15 in-lb (1.7 N-m).
Figure 3-6. 720i Enclosure Backplate
Torqued screws may become less tight as the gasket is compressed during torque pattern, therefore a second
torque is required using the same pattern and torque value.

3.8 CPU Board Removal
If the 720i CPU board must be removed, use the following procedure:
1. Disconnect power to the indicator.
2. Remove the backplate as described in Section 3.2 on page 7.
3. Unplug connectors for power to the board, serial communications, digital I/O and any installed option cards.
4. Remove any installed option cards.
5. Remove the five Phillips head screws and the kep nut from the CPU board.
6. Remove CPU board from the enclosure. If necessary, cut cable ties to shift cables out of the way.
To replace the CPU board, reverse the above procedure. Be sure to reinstall cable ties to secure all cables inside the indicator
enclosure.
3.9 Battery Replacement
The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM when the
indicator is not connected to AC power.
Data protected by the CPU board battery includes time and date, truck and tare memory, and onboard database information.
Use Revolution™ to store a copy of the indicator configuration on a PC before attempting battery replacement. If any data is
lost, the indicator configuration can be restored from the PC.
Watch for the low battery warning on the LCD display and periodically check the battery voltage on both the CPU board and on
any installed memory option cards. Batteries should be replaced when the indicator low battery warning comes on, or when
battery voltage falls to 2.2 VDC. Life expectancy of the battery is ten years.
3.9.1 Replacement Procedure
For best results, replace the battery while in weigh mode and with AC power applied. Use care not to bend the battery retaining
spring.
If the battery must be replaced with power removed, do the following immediately after restoring power:
1. Enter setup mode.
2. Navigate to the Version menu and press the RSConfig softkey. If connected using Revolution, configuration can be
reset by using monitor mode to enter the RESETCONFIGURATION command followed by the RS command.
See Figure 3-2 on page 10 for CPU board battery location and orientation (positive side up).
There is a risk of explosion if battery is replaced with the incorrect type. Dispose of batteries per manufacturer
instruction.
