Page 14: Gateway Operation
Gateway Operation Refer to the diagram below when following the procedures outlined in this section. IMPORTANT: When no remotes have been added to the system, the Form-C relay output will be in an alarm condition and the heartbeat LED will flash slowly. -
Page 15: Gateway Power Up - No Remotes Added Yet
Set the network address by sending a unique value to MODBUS address 40051. Enter this unique value on the „M2 Wireless Setup Sheet‟ included with this manual. Verify that the value was programmed via the MODBUS map. IMPORTANT! Network address must be programmed before Learn Mode can be enabled. -
Page 16: Gateway Power Up - Power Input Is Less Than 6.1 Volts, Greater Than 5.0 Volts
As soon as all Remotes report in subsequent to Gateway power up, the „Form C” output will be connected between „COM‟ & „NC‟. In the event all Remotes do not report in within 90 seconds, the „Output‟ LED(s) corresponding to the Remote(s) that have not reported in will be illuminated and the „Form C‟... -

5. Press and hold the PROGRAM button on the Gateway until the COP (MISC) LED flashes three times, then release. 6. The COP (MISC) LED should begin flashing rapidly indicating that the Gateway has entered „learn mode‟ and is waiting for a remote to initiate the learn operation. 7. -
Page 18: Installing Remote Units
Installing Remote Units Read MODBUS address 40016. This will contain the remote ID of the next remote you will be adding to the network. Label the next remote to be added with the value contained in address 40016. This is done to create a reference between the remote and the MODBUS map. NOTE: The first 8 remote units correspond to Gateway LEDs 1 through 8. - Page 19 7. Trim wires and strip ends approximately 9/32 inch minimum. 8. Place wire ends in slot and screw down until snug. NOTE: Make sure wire connects directly to the J301 terminal without looping the wire inside casing. 9. Rotate the remote unit clockwise to 90° vertical position.

Page 20: Learn Operation
Learn Operation NOTE: After performing the Learn Operation, you will want to reset the heartbeat counters so that accurate statistics can be recorded. Use the PC to send a command to the Gateway to Reset Heartbeat Counters (see page 13). This will clear any LED fault lights on the Gateway as well. NOTE: The remote and Gateway must be a minimum of 2 feet apart at all times. -

3. Initiate Learn Operation at the Remote by pressing and holding the Activation Button (S301) on the Remote until DS302 flashes two times, then release. 4. Learn Operation Visual Indication o Learn Operation Succeeded: Remote: DS301 will flash rapidly followed by DS302 flashing two times to confirm success. -

5. Confirm that the MODBUS registers associated with the Remote have been reset to zero. See the insert for a listing of these registers. 6. Reset Heartbeat Counters (see page 13). How to Install a Battery in the Remote IMPORTANT: USE ONLY AUTHORIZED 3.6 VOLT LITHIUM BATTERIES. -
Page 23: Modbus Register Access
MODBUS Register Access Gateway: MODBUS Registers 1-199 See the MODBUS map overview for more information (see below). Remote: Each Remote is provided with a dedicated range of 50 (fifty) MODBUS registers as outlined in the table below. Access to a remote is made by adding the MODBUS register you wish to access to the base address of the remote in question. -
Page 24: How To Program The Remote Configuration Registers
How to Program the Remote Configuration Registers The configuration registers contain information that tells the Remote how to operate. They generally contain information related to sensor operation and behavior. For instance, it will tell the remote whether a discrete input is configured as normally open or normally closed, whether a thermocouple is type J or type K, etc. -
Page 25: General Operation: Discrete Remote - One Channel
General Operation: Discrete Remote – ONE CHANNEL The sensor polarity for a single channel discrete remote can be configured for a Normally Open (NO) or Normally Closed (NC) sensor contact. A Discrete Remote is a very low power device that utilizes sleep functionality to extend battery life. -
Page 26: How To Configure A Discrete Remote - One Channel
How to Configure a Discrete Remote – ONE CHANNEL Configuring a Remote for NO/NC operation is done by programming Configuration Register 0 (CONFIG_0) which is located at MODBUS register 38 in each Remote‟s register space. NOTE: The Remote will initially be programmed for Normally Open (NO) operation. -
Page 27: General Operation: Thermocouple Remote - One Channel
General Operation: Thermocouple Remote – ONE CHANNEL A Thermocouple Remote (TC Remote) can read either Type K or Type J thermocouples and it reports temperature in Fahrenheit. The TC Remote reports two temperatures to the Gateway every time it sends a heartbeat. These temperatures are located at: Register 17 into the Remotes register space (217, 267, …) Ambient Temp... - Page 28 The TC fell below the last heartbeat reading by more than the allowed amount. o Default is 10F The TC rose above the last heartbeat reading by more than the allowed amount. o Default is 5F The TC returned within the absolute temperature range after being outside, but has not passed beyond a hysteresis threshold.

Page 29: How To Configure A Thermocouple Remote - One Channel
How to Configure a Thermocouple Remote – ONE CHANNEL Configuring a Thermocouple Remote is done by programming Configuration Registers 0 -> 6 (CONFIG_0 -> CONFIG_6) which are located at MODBUS register 38 -> 44 in each Remote‟s register space. NOTE: See How to Program Remote Configuration Registers for additional information on programming the Configuration Registers. -

Page 31: Deep Sleep
Deep Sleep The M2Wireless system can be placed into deep sleep when the operator knows that the Gateway will be powered off for more than a few days. This will significantly conserve Remote battery life. IMPORTANT: It may take up to ten minutes to wake up from deep sleep. Because of this delay, be sure to power up the gateway at least ten minutes before needing the system to be operational. - Page 32 Remotes Automatically Enter Deep Sleep In the event the Gateway is powered off for more than 1 week, the Remotes will automatically enter Deep Sleep. IMPORTANT: It is important to recognize that the Gateway does not know that the Remotes entered Deep Sleep. Because of this, the Gateway will likely indicate a fault condition at power up because the Remotes will not be reporting in as expected.
- Page 33 Wakeup After the Operator Manually Tells the Gateway to Enter Deep Sleep Because the Gateway is aware that they system was placed in Deep Sleep mode prior to power-down, the Gateway will expect the Remotes to take additional time to report in. 1.
