Normal Mode. Use this setting when the board is used with an eCNA-10.
Emulation Mode. In this mode, the board emulates the 39331 Booth
termination board in order to be compatible with older CNA automations.
4) Status LED - This indicates the status of the on-board computer. If the computer is operating
properly, it will indicate one of three conditions.
1: A fast (.2 second) blink rate indicates the computer is working and communicating properly
with the eCNA-10 main control board.
2: A slow (1 blink ON, 2 seconds OFF) rate indicates since power up, the board has not
received data from the eCNA-10 main control board. The I/O is disabled.
3: A slow (2 blinks ON, 2 seconds OFF) rate indicates a communication timeout.
Communications were once established and subsequently lost. The I/O is disabled.
5) 12 Volt Power - TB4 (1-4) are the +12 volt power connections. This is normally used for
‘contact sense’ input wiring, but can be used to power any 12 volt device such as an external
relay. The supply is fused at 1/4 amp.
6) Inputs - TB4 (5-20) are the low voltage isolated input connections. Inputs can be wired for
either ‘contact’ or ‘voltage’ sense. All inputs are de-bounced and require a minimum pulse
width of 0.5 seconds.
Input Range: 5VDC - 34VDC, 3.6VRMS - 24VRMS @ 20mA Max.
7) Low Power Relay Outputs - TB5 are the Aux Out and Sound low power output connections. All
relay contacts are ‘dry’ and require an external power source.
Contact Maximum Ratings: 30VRMS @ 2 Amps / 60VDC @ 1 Amp
8) Aux Out Override Connections - P4 header is for the optional low power override cable.
9) Lights/Curtains Override Connections - P3 header is for the optional low power override cable.
10) High Power Relay Outputs - TB3 are the high power output connections. The relay contacts are
‘dry’ and require and external power source.
Contact Maximum Ratings: 250VRMS @ 10 Amps / 30VDC @ 10 Amps
11) Low Power Relay Outputs - TB2 are the Masking, Curtain and Lights low power output
connections. All relay contacts are ‘dry’ and require an external power source.
Contact Maximum Ratings: 30VRMS @ 2 Amps / 60VDC @ 1 Amp
12) Masking Override Connections - P2 header is for the optional low power override cable.
13) LSN - TB1 (6-8) and P6 are the Local Sync Network connections. This is a tie point only.
Note: The LSN is not used on the eCNA-10.
14) LIN - TB1 (1-5), P1 and P5 are the LIN connections. This is the serial data and power
connections from the main control board.
