1. Either create new field unit or find existing field unit.
2. Write down the Field Unit Address of the Irrinet that you wish to set up in the field.

1. From Central Definitions write down System Address and Radio Communications.

• This radio communication could be Trunked Radio, SmartNet Trunked Radio, Radio B + Line or Radio C + Line.
• Field Unit Address, System Address and Radio Communications are important things to document before going into the field.

  ---

Next it is important to know and understand the location of the IRRInet CPU radio ports and the location of the radios on the IRRInet.

IRRInet Radio locations        IRRInet CPU Radio Ports

Now it is time to plug in the keyboard. Communication Definition Setup in the IRRInet can be found in General Information.

1. To find General Information, plug in the keyboard terminal.
2. Press escape (ESC) and press F5 till you find General Operation (F3-GENERAL OPER.).

1. Press F3, this takes you to the first General Operation screen. We are looking for Communication Definition (COMM. DEF). Press F5 to advance to the next General Operation screen then press F1 (F1-COMM. DEF) and you will see the first step in setting up communications.

1. Enter in your System Address and press Enter (ENT), right arrow key over to Unit.
2. Enter in Unit Address and press Enter.
3. Press the Right arrow key and you will enter into the Radio Ports.

• Typically there are two Radio Ports: Rad 1 and Rad 2.
• By default Rad 1 is set up to talk to the Remote and Line is set up to talk to the Center.

1. Press the Right Arrow till you see the Wireline setup.
2. Change the direction that the Line Port is pointed to from CENTER to DISABLE by pressing F1.

1. Now you can press the Left Arrow key twice till you see the RAD1 Port.
2. Press F1 once and the direction Radio 1 is pointed will change to CENTER+REMOTE.

• Center + Remote is used when your Radio at the Central Computer is on the same frequency as the Scorpios.
• This direction is not used if you are using Trunked Radios, Repeaters or 800/900 Conventional.

1. Press F1 and the direction will change to DISABLE.
2. Press F1 again and the direction will change to CENTER.

If Radio 1 is the desired radio to talk back to the Central leave the direction of RAD1 set to CENTER.

By default F2-COMM. is set to Radio.A.

1. Radio A
2. Radio B
3. Radio C

Radio A, B and C typically are used with Conventional radios and Repeaters. Radio B is typically used and occasionally Radio C is used when you are going through a Repeater.

• TRUNK A
• TRUNK B
• TRUNK C

Trunk B is typically the preferred communication if you are using Trunk Radio.

The Communication should match the Communication in Central Definitions:

• If the Communication at the Central is Trunked B then Communications RAD 1 should be set to Trunked B.

• TR. SMARTNET A
• TR. SMARTNET B
• TR. SMARTNET C

Again TR. SMARTNET B is the preferred communication.

Channel Monitor is used by the IRRInet to monitor traffic on the radio's frequency. Channel Monitor tells the Irrinet CPU it is ok to transmit or wait to transmit. You are a channel monitor when you use two portable radios, if you hear someone talking you do not try to talk over them.

Press F3 and C.M. will change from HIGH to LOW,

Press F3 again and it will change to DISABLE.

• Disable tells the IRRInet to transmit even if there is traffic on the frequency. This will lead to communication failures.

Typically the Channel Monitor should be left at its default HIGH.

1. Press the Right Arrow key and you will be at the set up screen for RAD2.

• The default direction for Radio 2 is DISABLE.
  • Press F1 and the direction that Radio 2 is pointed to will change to REMOTE.
  • Press F2 and Communication will change from RADIO.A to RADIO.B.
  • Leave Channel Monitor at its default HIGH.

• Click on your Radio setup to see actual RAD1 and RAD2 keyboard Screens.

• Conventional Radio and Remote
• Conventional Repeater and Remote
• Trunked Radio and Remote
• Trunked Smartnet Radio and Remote
