1Introduction
The AT Series Communications option allows the user to remotely monitor and control the
AT Series Battery Charger over a serial connection. Everything that the user can do at the
charger’s front panel display is accessible remotely. The communications option supports
DNP3 Level 2 and Modbus protocols over RS-232 or RS-485 serial communications.
Configuration is done by DIP switches and a setup program for additional parameters. The
communications board supports baud rates of 9600 bps and 19200 bps.
2Protocols
2.1 Modbus
The communications option can be setup to communicate on standard Modbus networks
using either of two transmission modes: ASCII (American Standard Code for Information
Interchange) or RTU (Remote Terminal Unit). The advantage of ASCII allows less strict
serial timing requirements without causing communication errors. The advantage of RTU
allows more data to be transmitted than ASCII mode for higher throughput.
Modbus ASCII mode supports the following serial settings:
• No parity, 7 data bits, 2 stop bits
• Even parity, 7 data bits, 1 stop bit
• Odd parity, 7 data bits, 1 stop bit
Modbus RTU mode supports the following serial settings:
• No parity, 8 data bits, 2 stop bits
• Even parity, 8 data bits, 1 stop bit
• Odd parity, 8 data bits, 1 stop bit
Refer to the Modbus section on page 28 for information on its implementation.
2.2 DNP3
The communications option supports DNP3 Level 2. This implementation of DNP3 meets
Level 2 conformance and supports change events with unsolicited messaging.
The DNP protocol supports the following serial settings:
• No parity, 8 data bits, 1 stop bit
• No parity, 8 data bits, 2 stop bits
• Even parity, 8 data bits, 1 stop bit
• Odd parity, 8 data bits, 1 stop bit
Refer to the DNP V3.00 section on page 17 for information on its implementation.

3.1 Installation
WARNING
Disconnect and lock out all power to the battery charger before starting any maintenance
procedures. Turn the AC power off at the distribution panel upstream from the battery
charger. Disconnect the battery from the charger output terminals. This includes remote
sense wires if they were installed.
CAUTION
This part is susceptible to damage from static discharge. Please use the following
precautions:
• If you have a ground wrist strap, please use it to ground yourself to the charger
enclosure using the ground stud on the back of the door.
• Touch the ground stud on the back of the door before handling circuit boards or other
static sensitive parts.
• Handle circuit boards only by their edges.
• Ground yourself again before you replace any connectors or terminals on the new
part.
• If you are replacing a static sensitive circuit board parts, be sure you are grounded
before removing the new part from its anti-static carrier.
Installation Steps
Step 1 Turn off the AC and DC circuit breakers on the charger. Using a voltmeter, verify
that all potential voltages on the I/O panel are zero. This includes the DC Output
terminals TB1(+) and TB1(-), and the Remote Sense terminals (+) and (-).
Step 2 Locate the stand-offs that hold the main control card. Use a needle nose pliers to
pinch the retaining ear on the stand-offs, and gently pull the main control card back
off the stand-offs, roughly 0.25 inches. It is best to unlatch all stand-offs first with
the main control card still resting on them. Finally, remove the main control card in
one motion.
Step 3 The EN5004-xx communications module pc board (A12) mounts to the left of the
EN5002-xx main control pc board (A1), with connector (P13) plugged into J13.
Make sure that the pins on the connector line up. See Figure 1.
Step 4 Position the boards over the stand-offs. Firmly push both boards onto the stand-offs
until they are fully seated under the plastic clips. Minimize pc board flexing by
pushing directly on the areas surrounding stand-offs holes. Check the front panel
for proper alignment of indicating lights and push button switches.

2 on J20 is +vdc and pin 4 is common. See Figure 2.
Step 6 Connect the serial connection to TB10 for RS-232 (see section 3.2.1 on page 5) or
TB11 for RS-485 (see section 3.2.2 on page 8).
Step 7 Check your work, read all the steps again and make sure that all the instructions
were performed.
Checks:
¨All stand-offs are fully latched.
¨All wire harness connectors are properly mated.
¨Indicator lights properly align with the front panel.
¨Push button switches work properly.

3.2 Serial Connections
The communications option supports RS-232 and RS-485. RS-232 is a standard serial
communications used on personal computers. It has a limited cable distance and is
acceptable to electrical noise. RS-485 serial communications allow longer distances and
allow multiple devices to be connected to the same serial network. TB10 terminal block is
for the RS-485 connections and TB11 terminal block is for the RS-232 connections.
3.2.1 RS-232
Set configuration switch S1-5 to OFF to select RS-
232. Configuration switch S1-6 Enables or Disables

TB11 is for the RS-232 user connections. In each section for RS-232 3-wire and 5-wire
installation, a typical connection diagram is shown. Each diagram shows the pinout used for
a standard personal computer (PC) for either a 25-pin or 9-pin serial connection.

3.2.2 RS-485
The communications board supports half-duplex RS-485 communications. Set configuration
switch S1-5 to ON to select RS-485. TB10 terminal block is for the RS-485 connections.
The next two sections describe a single connection and multi-drop connection.
Some RS-485 networks may require terminating resistors at both ends of the serial network.
The decision of whether or not to use termination resistors should be based on the BAUD
rate, the cable distance, and the type of cable being used to build the network. In most cases
for BAUD rates under 19.2K, terminating resistors are not required. If termination resistors
are used, the network must be designed with the appropriate biasing resistors to ensure
reliable communications.
The biasing resistors are responsible for ensuring that the network remains in the idle state
when all drivers are tri-stated. In order to guarantee that the receivers remain in a known
state, +/-200mV must always be maintained across the (+) and (-) or (A) and (B) RS-485
inputs. The use of termination resistors requires a significantly lower value of biasing
resistors which results in greater dc loading of the network.
Network design and biasing resistor calculations depend on the number of nodes on the
network, the type of drivers and receivers on the network, and any biasing already designed
into other devices sharing the network. As a result, whether or not use termination resistors
and biasing resistor calculation is beyond the scope of this manual. For more information on
biasing and termination details see the following references:

http://www.bb-elec.com/tech_articles/rs422_485_app_note/table_of_contents.asp
The communications board has a termination resistor built in. Jumper J22 enables or
disables the terminating resistor. If the host computer is on one of the ends and does not
have a built in terminating resistor, add the resistor at the connection across the plus (+) and
minus (-). Each device needs to have a unique address number. Refer to Section 4for
configuration information for either Modbus or DNP protocols.

3.2.2 RS-485 Single Connection
When a single device is connected using RS-485, the terminating resistor is required. Move
the jumper on J22 to pins 1 and 2 to enable the terminating resistor. The device
communicating with the charger needs its own terminating resistor installed.

RS-485 Single Connection

HARDWARE

3.2.2 RS-485 Multi-Drop
When multiple chargers are connected using RS-485, the devices on the ends of the network
needs a terminating resistor installed or enabled. On the communications board, moving the
jumper on J22 between pins 1 and 2 enables the terminating resistor. The devices in the
middle of the network do not require the terminating resistor. Move jumper on J22 between
pins 2 and 3 to disable the terminating resistor. Figure 6 and Figure 7 show examples of
multiple chargers on a RS-485 serial network.

3.3 Using a Modem
These instructions are for a U.S. Robotics modem product # USR5686D or equivalent with
auto answer feature.
If using Modbus protocol, use ASCII mode. RTU mode has tighter timing requirements that
might prevent communications while using the modem. ASCII mode is enabled by
configuration switch S1-4 in the ON position. Enable the RS-232 handshaking lines by
setting the configuration switch S1-6 to the ON position. Connect the modem to TB11 as
detailed in Figure 8. Set the baud rate to 9600 bps by setting the configuration switch S1-7 to
the OFF position. Set the modem up for the settings listed below. The telephone cable plugs
into a standard analog phone line. This modem will not work with office digital phone
systems. The telephone line needs to be a dedicated analog phone line similar to most fax
machines. Plug in the AC power supply. The host software needs to have the same protocol
and serial parameters as the communications option.

4Configuration
All user configurable items are controlled by two groups of switches and a setup program to
modify additional configuration parameters. After changes have been made, the charger
must have both the AC and DC circuit breakers turned OFF then back ON again for any
changes to take affect.
S1 is used to configure the communications interface. S2 is used to set the device address for
Modbus. Setting S1-1 to enable the Setup Program, allows modification to additional
configuration parameters.

4.4 Status LED (D1)
The EN5004-xx communications module pc board (A12) features a Status LED (D1) built
into the board, located to the left of the Configuration Switches (S1). See Figure 2 on page 5
for location. During normal operations the LED will flash very quickly to indicate
communications with the host computer. Use the following guide for LED troubleshooting:
4.4.1 Blinking LED
On power up the D1 will blink on and off at a steady rate of 1 sec. on and 1 sec. off to indicate that the
Modbus Address selected by the DIP switches S2 is invalid. The acceptable Modbus address range is 1-
247. For example, if all the switches for S2 are set to off for an address of 0, the LED will blink for an
invalid address.
4.4.2 LED Always Off
The LED will flash when the communications board receives and processes data from a host computer.
When the LED does not flash, then the communications board is not processing the data being sent to it by
the computer. Check the following items to al items can be the cause of no communications.
•Verify that the connection P13 is aligned properly with J13 on the main control card.
•Make sure the power supply connection J20 is plugged in.
•Measure the voltage of J20 pins 2(+) and 4(-) with J20 plugged in. It should be between 7-10vdc.
•Check the communications wiring from the host computer to the communications board.
•If the communications board is wired for RS-232 make sure RS-232 is selected in the DIP switches.
•If the communications board is wired for RS-485 make sure RS-485 is selected in the DIP switches.
•Check all the communication configuration settings.
•Verify the host computer's communications settings match the charger communications board settings
(protocol, address, baud rate, stop bits, data bits, etc.).
4.4.2 LED Always On
If the LED is always on then this indicates the communications board is not working. Check the
following:
•Verify that the connection P13 is aligned properly with J13 on the main control card.
•Make sure the power supply connection J20 is plugged in.
•Measure the voltage of J20 pins 2(+) and 4(-) with J20 plugged in. It should be between 7-10vdc.
