What is the Equipment Touch?
You wire the Equipment Touch to the controller’s Rnet port. The Equipment Touch must be powered by an external power source. The Rnet can have one Equipment Touch, plus ZS sensors and/or a Wireless Adapter that communicates with wireless sensors. NOTE The Equipment Touch cannot share the Rnet with SPT Sensors or a TruVuTM ET Display. You can install and run the Equipment Touch with only its built-in system screens, or you can create a customized touchscreen file in ViewBuilder. This requires that you: 1 Create customs screens in ViewBuilder, and then save the touchscreen (.touch) file. See “Working with
touchscreens” in ViewBuilder Help. 2 In the i-Vu® interface, right-click the controller and select Driver Properties to attach the touchscreen file. 3 Download All Content to the controller. See “Downloading to controllers” in i-Vu® Help.

Screen name Communication

Description

Lets you edit the information below for the controller. Touch a field to tap in new information.
BACnet Device Instance number Auto Generate Device ID­Enter No or Yes
You can edit the following fields that pertain to the controller’s MS/TP network:
Max Masters – Set this to the highest MAC address (up to 127) on the MS/TP network. If you later add a device with a higher address, you must change this field to that new address.
Max Info Frames – Specifies the maximum number of information messages a controller may transmit before it must pass the token to the next controller. CAUTION Increasing this number allows the controller to transmit more messages while it has the token, but it also increases the overall time it takes for the token to pass through the network.
· For a router, set this value to a high number such as 200.
· In non-router controllers, use the following formula to calculate this value:
[2 – (devices (.002 + (80/baud))] / [(600/baud) devices] = Max Info Frames For example, if the network has 15 devices at 19200 baud, Max Info Frames would be 4.
NOTE You may need to increase the result of the formula for controllers that need to communicate many values to other devices.

What is the Equipment Touch?

Screen name Time Master

Description

If the system does not have a front-end, you should designate a controller to be the BACnet Time Master. If a controller will be the BACnet Time Master, this screen lets you configure how it sends time synchronization broadcasts.
Time Sync Mode – Tap in the number below that represents your selection:
· 0 = No Broadcast – The controller does not act as Time Master.
· 1 = Local Broadcast – If it does not already exist, a BACnet address with network number and MAC address length both set to zero is added to the controller’s Time Synchronization Recipients list found on the driver’s Device page in the i-Vu® interface. The controller then sends time broadcasts only to controllers on its ARCnet or MS/TP network.
· 2 = Global Broadcast – If it does not already exist, a global address with network number set to 65535 and MAC address length set to zero is added to the controller’s Time Synchronization Recipients list found on the driver’s Device page in the i-Vu® interface. The controller then sends time broadcasts to all its connected networks.
Time Sync Interval – Enter how often local or global time broadcast should be sent (1-9999 minutes). If Time Sync Interval is set to zero, no time sync messages are sent.

Touchscreen Setup

NOTE If the controller looks through its Time Synchronization Recipient List and finds an entry with MAC address length set to zero and network number set to 65535, the controller’s BACnet Time Master mode is set for Global Broadcast. If there is no global broadcast entry in the recipient list, the controller then looks for a local broadcast address (MAC address length set to zero and network number set to zero or to the same network number as the module’s). If such an entry is found, the BACnet Time Master mode is set for Local Broadcast. Otherwise, the mode defaults to Disabled/None.
Lets you edit the touchscreen settings (page 20).

Wiring and mounting the Equipment Touch · Wire the Equipment Touch in a daisy- chain configuration with other Rnet devices as shown below.

NOTE You do not need to set an address for the Equipment Touch.

Wiring specifications

Power wiring
2-conductor wire 18 AWG for distances up to 100 feet. All transformer secondaries must be grounded. Wiring connections must be in accordance with NEC and local codes.

Rnet wiring
NOTE If you wire the Equipment Touch directly to the controller’s Rnet port, you can use a 2-conductor cable instead of the standard 4-conductor Rnet cable.

Wiring and mounting the Equipment Touch
To wire and mount the Equipment Touch
1 Remove the backplate from the Equipment Touch. While firmly pressing the 2 tabs on top of the Equipment Touch, pull on the backplate with your index finger until the backplate releases from the Equipment Touch.
2 Pull the power and communication wiring through the hole in the center of the backplate. See figure in step 5.
3 If wiring 1 cable to the Equipment Touch, cut the shield wire off at the outer jacket, then wrap the cable with tape at the outer jacket to cover the end of the shield wire. If wiring 2 cables in a daisy-chain configuration, twist together the shield wires, then wrap the shield wires with tape.
4 Strip about 0.25 inch (0.6 cm) insulation from the end of each wire. 5 Connect wiring to the Equipment Touch as shown below:

CAUTION Allow no more than 0.06 inch (1.5 mm) bare communication wire to protrude. If bare communication wire contacts the cable’s foil shield, shield wire, or a metal surface other than the terminal block, the device may not communicate correctly.
