Product Overview
Introduction
The Gridstream SCADA Series 4 Single Board Radio (Gridstream S4SBR) is for use by OEM
vendors wanting to incorporate Gridstream capability into their SCADA/DA and similar products.
The design of the board allows integration with an OEM enclosure and communication with the
customer's equipment via a 14-pin connector. Table 1 - 4, "I/O Connector Pin Functions and
Acceptable Voltage Levels," provides details for the interface. The Gridstream S4SBR is available
in four unique versions, listed/numbered below and in the following illustration:
1. External Antenna (MCX connector), without Super Cap, Part number 40-1681
2. External Antenna (MCX connector), with Super Cap, Part number 40-1682
3. Internal Antenna, without Super Cap, Part number 40-1683
4. Internal Antenna, with Super Cap, Part number 40-1684
The Gridstream S4SBR is a self-contained 600 mW Integrated WanGate Radio (IWR) which
includes voltage regulation, micro-processor, and radio. Output power can be set to 100, 450, or 600
mW.

Chapter 1 - Product Overview
Landis+Gyr
This Gridstream S4SBR is based upon existing Gridstream architecture and will operate as a node
within a Gridstream network. It is similar in construction to a Gridstream metering endpoint, but
with an optional onboard antenna and I/O ports. It has received Modular FCC approval when used
with the approved cable and antenna.
The Gridstream S4SBR provides two digital I/O ports and two analog input ports, which can also be
configured as two general purpose I/O ports. One of the digital ports can also be configured as a
counter by sensing either the rising end of the pulse, trailing edge of the pulse, or both. These
interfaces are accessible via the Device Control Word (DCW) programming language.

NOTE: All Gridstream S4SBR models have identical base electrical architecture with minor physical
variations based on antenna/connector type and whether or not the super cap circuitry is included.
The on-board antenna version is designed for customers seeking the lowest-cost solution. The
onboard F-antenna exhibits nominal performance. The external antenna version is designed for
customers who require enhanced performance (greater range).
The Gridstream S4SBR shares similarities with other Gridstream IWR devices, but also has
differences.

Chapter 1 - Product Overview
Pin 1 (VIN)
This pin must be supplied with DC voltage between 4.0 and 7.0 VDC with 5.0 VDC considered
nominal.
The input voltage is linearly regulated on the board. While the linear regulation can remove some
noise, Power Supply Rejection Ratio (PSRR) varies with frequency. If the power source is
particularly noisy, filtering may be required. Landis+Gyr engineering can assist in defining radio
tests to determine if power supply noise is affecting radio performance.
The input voltage must be maintained between 4.0 VDC and 7.0 VDC during operation. The onboard electronics include fast-acting reset circuitry. If the voltage drops below 4.0 VDC, even
transiently, the system will reboot once the voltage returns to normal range. If the voltage rises above
7.0 VDC, even transiently, the voltage-sensitive components could be damaged.
Upon power up, the on-board processor and voltage regulator requires the supply voltage to have a
minimum of 0.05 V/msec slew rate - which implies rising from a logic 0 to a logic 1 in no less than
66 msec. Power consumption during normal receive mode is typically 41 mA. Current consumption
during 100 mW transmit mode is 250 mA, 440 mA during 450 mW transmit mode, and 520 mA
during 600 mW transmit mode.
During the first 30 minutes after initial power-on or after an extended outage, the on-board supercapacitor will be charging. During this time, the total input current to the device will increase by 80
mA. SeeTable 1 - 1, "Series 4 Gridstream S4SBR General Electrical Specifications," for additional
details.
The Gridstream S4SBR uses a frequency-hopping sequence transmission and, while typically rare,
transmissions can be as long as 400 mS in duration, and can theoretically sustain at a 45% duty cycle
on a single channel.

Pin 2 (LPP TX) and Pin 3 (LPP RX)
These pins are used to interface with the device's LAN Packet Port. These pins are driven at TTL
level supply, 2.5 VDC.
Baud rates on this port default to 9,600 bps but, using RadioShop, are configurable from 1,200 bps to
115,200 bps.
To reduce chances of electrical damage, a 10Kohm series resistor is placed in-series with the pin
which limits the drive current capability of this pin.
Stray physical capacitance on this circuit should be kept below 250[pF].

NOTE: These pins should NOT be directly connected to an RS-232 interface on a computer. Where
such a connection is necessary, the developer must connect to the unit through an externallypowered TTL to RS-232 VDC converter, NOT via the pins or the RS-232 connection on the
computer.
Pin 4 (DIGITAL_IO1) and Pin 11 (DIGITAL_IO2)
These pins are general purpose digital I/O lines and are driven at TTL supply levels.
If not used, they should not be left unconnected and should be held low by connecting the pin to a
common ground.
If used, these pins must be driven to a valid logic high or low and not left at intermediate voltages as
this will result in indeterminate logic values and may damage the device.

Pin 5 (ANALOG_IN1) and Pin 10 (ANALOG_IN2)
These pins are analog inputs to the device. Voltages must be scaled to the 0 to 2.5 VDC range. The
Gridstream S4SBR returns the DC voltage as HEX values in the memory locations as described in
“Analog Input Functionality” on page 31.
To obtain the HEX values, a DCW must be developed to read and send the HEX values to the host
computer. Once the host has the HEX values, the corresponding voltage can be derived using the
following formula:
•
Voltage = (Decimal value/1023) * 2.5
The DCW that reads the memory location returns a HEX value, within range of 0x0 - 0x03FF. The
user can convert to decimal using the formula obtaining the value in VDC. The table below shows
examples of various voltages and the equivalent HEX values.

Pins 6 and 7 (GND)
These pins are the ground connection for both power and communications. These two pins are tied
together on the device.
Pin 8 (LOW_RF_POWER)
The purpose for this pin is to reduce the RF output power level to assure operation during
development and OEM manufacturing process. A logic high on this pin leaves the device in its
normal mode of operation, functioning with full rated RF transmitter power. This pin may also be
left unconnected and would therefore result in normal mode operation due to onboard pull-up.

A logic low (pin connected to ground) reduces the RF output power level to approximately 100 mW
for use in environments where high RF output power is not required or only low input power is
available to the device. When the USB cable is used to power the board, the pin is automatically
brought low. This pin is a digital input, driven internally at TTL supply level.
This pin must be left not connected or pulled low to ground as intermediate voltages will result in
indeterminate conditions and may damage the device.
Pin 9 (PWR_DN)
This pin is used to enable or disable the Gridstream S4SBR. It is a digital input and must be driven to
a valid logic high (5.0 VDC) or low (GND), since intermediate voltages will result in indeterminate
logic values and may damage the device.

NOTE: When the Pin 9 power-off command is asserted on super-capacitor units, the unit will remain
operational for a few minutes as the super-capacitor voltage bleeds off. Once Pin 9 power-off
command is asserted on units without the super-capacitor, the units will turn off immediately.
•
A logic high (5VDC) provides power to the device.
•
A logic low (GND) turns off the device.
Prior to turning off the device, all interface signals must be driven low and logic voltage removed.
This includes all TTL logic lines, digital and analog I/O lines.
When the device is turned off with this pin, total current consumption will be less than 100µA.

NOTE: When the board is not in use, voltage should not be applied to any interface. Applied voltage
may damage the device as destructive latch-up may occur.
Pin 12 (TPP RX) and Pin 13 (TPP TX)
These pins are used to interface with the device's Transparent Port. These pins are driven at TTL
supply level.
Baud rates on this port default to 9,600 bps but, using RadioShop, are configurable from 300 bps to
115,200 bps.

Pin 14 (3.3V_Logic_supply)
This pin is used as an output to provide 3.3V for the purpose of logic interfacing. To reduce chances
of electrical damage, this pin is current limited to 300uA and caution should be taken when
connecting to external circuit to ensure it doesn’t exceed the 300µA limit.

CAUTION: Pin 14 should NOT be used whenever Pin 9 (PWR_DN) is held in logic low level.
USB Programming Cable
A USB Serial Interface programming cable (P/N 19-2325, shown in Figure 1 - 6) is available for
developers to access the device via the LPP Port using RadioShop or their own application.
The cable provides power (5.0 VDC) from the USB port and a single emulated COM Port
connection. The USB cable allows the OEM vendor to configure, load DCWs, and program the
Gridstream S4SBR via the LPP port.
Figure 1 - 6. USB Serial Interface programming cable
The cable converts TTL level signals for connecting to Serial interfaces (COM Ports) via the USB
interface. The cable is designed to allow for a fast, simple way to connect the board via the USB
interface to the virtual RS-232 COM Port on the PC, allowing the developer to access the board
using RadioShop.
The entire USB protocol is handled by the USB Serial Interface cable when connected to the PC,
thus no USB specific firmware programming is required.

WARNING: The 19-2325 USB Cable requires a USB 2.0 port for proper operation. PC damage
may occur if the 19-2325 USB Cable is connected to a USB 1.0 port.
NOTE: Previous model (19-1220) USB cables will not function correctly with this unit.
In order to be compatible with most computer USB ports the USB 19-2325 cable maintains a current
limit of less than 500mA by setting the Gridstream S4SBR to low RF output power mode by
grounding pin 8 of the I/O connector.This mode sets the output power level to approximately 100

Antennas
As with any RF device, antenna-related decisions are critical and must be made early. The RF range
of the final product will depend greatly on the choice of antenna and where it is placed. The S4SBR
is available in four versions, selected at the time of order. The on-board antenna versions are built
and tuned to utilize an on-board F-antenna. The external antenna versions include an on-board
50-ohm MCX connector for RF co-ax connection to an external antenna.
External Antenna
An external antenna is connected to the board via an MCX Female coaxial RF connector.
The external antenna used to qualify the board is an omnidirectional 5 dBi whip (shown in the next
figure), made by Manufacturers Marketing Group (MMG). The MMG part number for this antenna
is 16-1000-0. MMG contact information is on page 35. This antenna can be used, or any other
omnidirectional whip antenna with 5 dBi gain or less.

Troubleshooting
The Gridstream S4SBR has been designed as a Field Replaceable Unit (FRU). As such, there are no
serviceable parts in the unit.
If you suspect parts within the Gridstream S4SBR have failed:
1. Inspect the module to determine if there is any visual indication of damage to the unit.
2. Verify that power is being supplied to the unit. If the power is within operating parameters,
proceed to Step 3.
3. Try to connect with a locally connected Series-4 IWR configured the same as the Gridstream
S4SBR. If, after five minutes, the locally connected Series-4 IWR does not acquire the
Gridstream S4SBR in its neighbors list, the Gridstream S4SBR should be replaced.

Depending on the desired method used to establish communication, connect a USB cable to either
the Transparent Packet Port (TPP), the LAN Packet Port (LPP) connection, or both.

NOTE: To provide power to the Gridstream S4SBR test Platform, the power input must be supplied
externally (as shown) because the USB cable, when connected to the TPP or LPP connector, does
not provide power for the test board.
Set the USB power input to an appropriate level by toggling the switch (P) controlling the
*PWR_DN signal (pin 9) to OFF position.
Connect the Gridstream S4SBR to the test board through the board-to-board I/O connector (located
under the SRB).
Toggle the switch (P) controlling the signal (pin 9) *PWR_DN to the ON position to turn the
Gridstream S4SBR ON.
The switch (LP) controlling *LOW_RF_POWER may be toggled to set (pin 8) the transmit level of
the Gridstream S4SBR under test. This switch will control whether to transmit with limited or full
power.
Gridstream S4SBR Logic
Developers planning to use the Gridstream SCADA/DA Series 4 Single Board Radio (Gridstream
S4SBR) in their SCADA equipment as a monitoring device should be aware of the logic of the
setting when writing a DCW program. The following describes the logic for reading and writing

Digital I/O Functionality

NOTE: This device provides two general purpose digital I/O lines. These are controllable through
the DCW programming language. It is outside the scope of this document to describe that
language but, in brief, there are mechanisms by which each line can be independently configured
as input or output. 

The state of inputs can be read, and the state of outputs can be set. DCW code execution operates
as a virtual environment and, as such, does not support rapid transitions. Users should understand
the speed limitations associated with the use of these digital I/O pins.
The register below can be used to control either of the two general purpose I/O pins (D1 & D2)
located at memory location 7700 (hex).

NOTE: The actual sampling time is 0.25 μS and the conversion time is 2.75 μS, but the rate at which
signals on these inputs can be sampled in-practice is limited by the DCW execution. It is
recommended that these channels be used only for DC voltage measurement, and that the
sampling rate can not exceed 100 mS.

Ground Plane Specifications

NOTE: Please note this antenna requires a ground plane (MMG P/N 17-1000-A). The ground plane
should be at least six inches in diameter. See Figure A - 2
“
“
Figure A - 2. Ground Plane Specification
If the enclosure for the board is metal and at least 6" across, and the antenna is connected directly to
the enclosure, no ground plane is required, as the enclosure is the ground plane. The radiation pattern
of the recommended antenna is of a traditional dipole (RF pattern as a donut). The orientation of the
antenna should be in the vertical position (straight up or straight down), such that the RF pattern is
omni-directional in the horizontal plane.
RF External Antenna Cable Specifications
An external antenna is connected to the board via an RF coaxial cable of the type as shown in Figure
A - 3. See page 49 for the product data sheet.
Figure A - 3. RF Coaxial Cable
The cable has a Reverse-Polarity N-Type Female/Jack connector on one end and an MCX Male
connector on the other. This cable is available from MMG in lengths of 6", 12", and 18".
The MMG part numbers and typical insertion loss for these cables are shown in Table 1:

conductor in a male threaded coupling nut mechanism.
This prevents mating with a standard non-polarized connector. This type of connector is required by

On-board Antenna
Specifications
The on-board antenna design is an F-antenna. This design was chosen because its performance is
more broad-band relative to a slot antenna, and its pattern is somewhat omni-directional. This
antenna's maximum gain is 0 dB and its efficiency is 45%. This product does not allow an external
antenna in conjunction to the on-board antenna.
Using the on-board antenna, the recommended placement of the Gridstream S4SBR is at the edge of
the OEM board, with the antenna-side edge of the board extending beyond the edge of the board,
hanging out into free space and facing up as shown in Figure B - 1. If the antenna on the board does
not extend out into free space, then the customer's board will load the antenna and affect the
radiation pattern.
Also, an RF-transparent enclosure must be used (plastic or similar). Do not enclose the board within
a metal box. If a metal box is required to house the assembly, then the external antenna version of the
product must be used.
The on-board F-antenna's radiation pattern in free space is nearly Omni-directional, but has nulls in
the direction of the 14-pin I/O connector. The best way to visualize the antenna's radiation pattern is
a semi-sphere about the antenna-side edge of the board.
The main radiating element is the long trace running the length of the board. The length of this trace
sets the resonant frequency of the antenna. The thicker F element, parallel to the feed element, is the
return path to ground. The length of the feed element and size of the gap between the feed and
ground elements dictate the match of the antenna.
