INCA Master Station Kit Board Connectors

This chapter gives details about connections and indications for:

• IP Flush Master - 1008031000
• IP OR Master Station - 1008015000
• IP Master Station Kit - 1008093000

P1 LAN port & P2 AUX port

P1:

LAN connector for 10/100 Mbit Ethernet connection. The station can be powered from this connection if the line supports Power over Ethernet (PoE).

The connector has two LEDs in front where the right (R) LED indicates Ethernet speed and the left (L) LED verifies Ethernet link and traffic. (L and R as seen from the connector side)

P2:

RJ45 connector for auxiliary equipment like IP camera, PC or a second IP station. This port does not have an individual IP address. It does not carry power for AUX equipment.

P1/P2

P3 - External Loudspeaker, Relay Output and External Power Input

6-pin plug-on screw terminal for external connections.

P3

• Pin 1/2 Connect to 1.5 W loudspeaker.
  • Typical impedance: 8 Ω
  • Recommended impedance: 6-25 Ω.
• Pin 3/4 Internal NO relay contact for door lock control etc.
• Pin 5/6 Connect 24 VDC for station power if PoE is not used. Pin 6 is positive.

P4 - Inputs and Station LED

6-pin plug-on screw terminal for external connections.

P4

• Pin 1/4 Input 1
• Pin 2/4 Input 2
• Pin 3/4 Input 3
• Pin 5/6 Station LED for call message info.

When "Station Type" is set as Master station in AlphaPro, the inputs are mapped as DAK 11, 12 and 13. When the "Station Type" is set as CRM in AlphaPro, the inputs are mapped as 251, 252 and 253.

J4, J40 & J41 - Keyboard and DAK LED

Keyboard matrix is available on connector J4 and on connector J40. Pin 1-9 is used.

In software you can choose between four different matrix types, see Keyboard Settings.

"Standard matrix" pinout on J4 and J40

J4 - Keyboard matrix

18-pin ZIF-connector for keyboard. The keyboard may have up to 10 dialling keys, M and C keys, 10 DAK keys, 10 soft keys, volume up/down and light dim up/down keys connected in a matrix according to the drawing.

J4

J40 - Keyboard matrix

J40 provides an optional keyboard connection on a pinheader.

J4 and J41 - DAK LED connection

Optional DAK LED connection. Connection to J40/J41 can either be to a pin header or soldered directly to holes in the PCB.

• J4/10 - J41/1 DAK1 Green LED
• J4/11 - J41/2 DAK1 Red LED
• J4/12 - J41/3 DAK2 Green LED
• J4/13 - J41/4 DAK2 Red LED
• J4/14 - J41/5 DAK3 Green LED
• J4/15 - J41/6 DAK3 Red LED
• J4/16 - J41/7 DAK4 Green LED
• J4/17 - J41/8 DAK4 Red LED
• J4/18 - J41/9 Common +3.3 V

The DAK keys and the DAK LEDs are programmed using IND commands in the Event Handler. DAKs 1 to 4 and Soft keys 1 to 4 are used in current master stations.

Privacy on/off is accomplished by pressing the C key for 2 seconds. A circled P is shown in the display during Privacy mode.
