DAQ ELECTRONICS Callisto IoG

Section 1--General

1.1 Overview

The IoG is a communications Gateway, that is an integral part of DAQ’s Callisto Series
of remote products. As such, IoG is compatible with all current Callisto IoX and Polaris
modules, and can be used stand-alone, or easily integrated into any existing Callisto
system. Combining the power and flexibility of the IoE, with the latest surface mount
technology, the module is a powerful, cost effective protocol gateway/converter. The
device supports, 4 serial ports independently selectable as RS232 or RS485, the entire
Callisto Protocol Library, and the flexibility of Callisto View configuration software.
Master station and IED protocols can be mixed and matched on a per port basis, with
individual point mappings for each communications channel. An input power range of 9­28 VDC allows it to be easily powered, while an Arcnet LAN interface allows for either
expansion of IoGs, or connection to an existing Callisto RTU, with a single cable.

1.2 Packaging

The IoG is mounted in a painted steel box. However, this enclosure has no NEMA
rating, is only meant for basic protection of the electronics. It is not meant for outdoor
installation of any kind, and must be placed in an appropriate auxiliary enclosure if
outdoor use is required.

1.3 Mounting

The IoG module can be mounted in any plane that is convenient for the user. two L­shaped mounting brackets and 6-32 x ¼” screws and lock washers are provided to
facilitate installation of the module to any flat surface. The L-shaped mounting brackets
are secured to the IoG module via the tapped screw holes on either side of the steel case.

Section 2--IoG Front Panel Layout

2.1 Input Power Header

Power is provided to the IoG module through the two-pin header at the right side of the
front panel. The IoG module will operate within an input voltage range of 9-28 VDC.
The included power adapter provides 12 VDC from a 120 VAC power source.
Alternatively, any power supply capable of supplying 9-28 VDC can be utilized.

A two-position plug is provided which inserts directly into the front panel input power
header. The plug has an opening for each position, into which a wire end is inserted.
Above each opening is a captive screw which, when tightened, secures the wire end to
the plug.

If using the DAQ-supplied power adapter, insert the wire with the white stripe on the
insulation into the plug position corresponding to the (+) polarity marking for the input
power header. Tighten the screw above the opening. Insert the wire with the solid black
insulation into the remaining opening, and tighten the screw above the opening.

If using a different power source, please observe the polarity markings for the input
power, and attach the power supply wires to the plug appropriately.

2.2 Reset Switch

The reset switch is located just to the left of the input power header. This switch will
restart the RTU in one of two modes of operation:

a) Functional mode – pressing and releasing the reset switch one time will reboot

the IoG, and place it into its normal operating mode. In this mode, all
configured applications are active, and the IoG carries on communication
with attached devices.

b) Default mode – pressing and releasing the reset button five times in rapid

succession reboots the IoG and places it into the default-operating mode. In
this mode, only the core IoG applications are running, and no communications
occur between the IoG and attached devices. This mode is useful for
diagnostic and troubleshooting purposes.

2.3 Heartbeat LED

The Heartbeat LED (just to the left of the reset switch) indicates proper execution of
software functions in the microprocessor, and is also used to determine the present mode
of operation.

In functional mode, the heartbeat LED will continuously toggle on for one second, then
off for one second. In default mode, the toggle rate will be approximately twice as fast,
i.e., on for one-half second, off for one-half second.

2.4 Arcnet Reconfiguration LED

The Arcnet Reconfiguration LED (just to the left of the heartbeat LED) indicates the
operational state of the Arcnet LAN, particularly in the case where two or more modules
are interfaced to form a distributed system.

An essential requirement in Arcnet LAN communication is that each connected node has
a unique Arcnet node address. If two or more nodes have the same address,
communication between nodes on the LAN will not be possible. The Arcnet
Reconfiguration LED will help determine if there is an Arcnet problem.

The Arcnet LED being on solid, or off completely indicates stability of the network. If
the LED is toggling, it implies a network problem that could be related to cabling, or
addressing. WHEN USING ONLY ONE IoG, THE ARCNET LED WILL

ALWAYS TOGGLE ON AND OFF. THIS IS PROPER OPERATION.

See Section 3.4 for the procedure for setting the node address.
