Basic Installation Guide (Analog Devices)

For Whozz Calling Basic POS 2, 4, and 8 units (Serial and Ethernet models)

Pre-Installation Checklist

  • [ ] Verify customer has analog phone lines (not digital PBX extensions)
  • [ ] Confirm Caller ID service is active with phone company
  • [ ] Count number of phone lines to be monitored
  • [ ] Determine connection method: Serial, USB-to-Serial, or Ethernet
  • [ ] Locate where lines enter building (demarc/phone closet)

Critical Wiring Rule

Whozz Calling devices MUST connect to Central Office (CO) lines coming into the building - NOT extension lines from a PBX/phone system. PBX systems do not pass analog Caller ID signaling.

Parallel Connection (Recommended)

Connecting Phone Lines - Ethernet Models

Scenario 1: Single-line wall jacks (RJ11)

  1. Unplug telephone cord from wall jack
  2. Insert unmarked modular Duplicator into jack
  3. Connect telephone to one side of Duplicator - verify dial tone
  4. Connect phone cord from other side to Whozz Calling "L1" port
  5. Repeat for additional lines

Scenario 2: Two-line wall jacks (RJ14)

  1. Unplug telephone cord from wall jack
  2. Insert 3-way Splitter marked "L1+L2 L2 L1" into jack
  3. Connect telephone to L1+L2 output - verify dial tone on both lines
  4. Connect cords from L1 and L2 outputs to CallerID unit ports L1 and L2

Important: 3-way Splitters must be specifically marked "L1+L2 L2 L1" - NOT unmarked duplicators from retail stores.

Ethernet Connection

  1. Connect Ethernet port to same network as POS displays
  2. Default static IP: 192.168.0.90 (may need to change to match your network)
  3. Use ELConfig tool to change IP: CallerID.com → Support → Diagnostic Tools → Ethernet Whozz Calling
  4. Set static IP within your IP scheme and outside DHCP range
  5. Ensure popup software is NOT running when using ELConfig

Wireless devices: Set "Duplicate Call Records" to 8 via: Configure → Set Duplicate Call Records

Serial Connection

  1. Connect serial cable from unit to computer COM port
  2. If no COM port, use USB-to-Serial adapter
  3. Verify in Windows Device Manager: Ports (COM & LPT)
  4. Configure POS software for correct COM port at 9600 baud

DIP Switch Settings - Standard US

All DIP switches should be in the DOWN (OFF) position for standard US installations.

Exception: UK, EU, and countries using ETSI FSK signaling: Set DIP #4 UP (ON), all others DOWN.

Testing

  1. Download Serial Loop II from CallerID.com/Downloads/Diagnostic-Tools/
  2. Close any POS software using the COM port
  3. Run Serial Loop and select COM port at 9600 baud
  4. Power cycle the unit - boot-up data should appear
  5. Make a test call - Caller ID should appear
