Gridstream SCADA/DA S5SBR
Quick Start Guide Landis+Gyr
3.5 Digital Input
Digital input to Gridstream S5 SBR can be tested by toggling the two switches on the test board that
correspond to D1 for DIGITAL_IO1 and D2 for DIGITAL_IO2. The switch will toggle between 0V and supply VDC.
3.6 Analog Input
Analog input to the Gridstream S5 SBR can be tested by tuning the two potentiometers on the test board that
correspond to A1 for ANALOG_IN1 and A2 for ANALOG_IN2. The input voltage should lay between 0 VDC and
2.5 VDC.
NOTE: With an on-board reference 2.5 VDC, the highest analog input the Gridstream S5 SBR may sense is
limited to 2.5 VDC. Although the processor on the Gridstream S5 SBR may withstand supply VDC analog input,
users are advised not to exceed 2.5 VDC.
3.7 General Usage Instruction
Depending on the desired method used to establish communication, connect a USB cable to the Transparent
Packet Port (TPP), the LAN Packet Port (LPP) connection, or both.
NOTE: To provide power to the Gridstream S5 SBR 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 have 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 S5 SBR 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 S5 SBR
ON.
The switch (LP) controlling *LOW_RF_POWER may be toggled to set (pin 8) the transmit level of the Gridstream
S5 SBR under test. This switch will control whether to transmit with limited or full power.
