NI-2100, NI-3100, NI-4100 Hardware Reference Guide
NI-3100 Specifications (Cont.)
Power Requirement: 900 mA @ 12 VDC
Memory: NI-3100 & NI-3100/ICS:
• 64 MB SDRAM
• 1 MB Non-volatile (NV) SRAM
NI-3100/256 & NI-3100/256/ICS:
• 256 MB SDRAM
• 1 MB Non-volatile (NV) SRAM
Compact Flash: 2GB or greater (upgradeable to 4GB - see Other AMX Equipment).
Note: AMX may increase Flash size at any time in response to market availability.
Weight: 4.55 lbs (2.06 kg)
Enclosure: Metal with black matte finish
Certifications: FCC Part 15 Class B, CE, and IEC 60950
Front Panel LEDs:
LINK/ACT (green): Blinks when the Ethernet cables are connected and terminated correctly. Also blinks
when receiving Ethernet data packets.
Status (green): Blinks to indicate that the system is programmed and communicating properly.
Output (red): Blinks when the Controller transmits data, sets channels On and Off, sends data strings,
etc.
Input (yellow): Blinks when the Controller receives data from button pushes, strings, commands,
channel levels, etc.
RS-232/422/485
(red / yellow):
Light to indicate that DB9 Ports 1 - 7 are transmitting or receiving RS-232, 422, or 485
data (red = TX, yellow = RX).
Relay (red): Light to indicate the relay channels 1 - 8 are active (closed). These LEDs reflect the
state of the relay on Port 8.
IR/Serial (red): Light to indicate the IR/Serial channels 1 - 8 are transmitting control data on Ports 9 -
16. LED indictor for each IR port remains lit for the length of time that IR/Serial data is
being generated.
I/O (yellow): Lights when the rear I/O channels 1 - 8 are active. The LED for each I/O port reflects the
state of that particular port.
Rear Panel Components:
RS-232/422/485
(Ports 1 - 7):
7 RS-232/422/485 control ports using DB9 (male) connectors with XON/XOFF (transmit
on/transmit off), CTS/RTS (clear to send/ready to send), and 300-115,200 baud.
ICSNet: 2 RJ-45 connectors for ICSNet interface (provided by optional
ICSNet daughter card).
ICSHub Out: RJ-45 connector provides data to a Hub connected to the Controller (provided by
optional ICSNet daughter card).
Relay (Port 8): • 8-channel single-pole single-throw relay ports
• Each relay is independently controlled.
• Supports up to 8 independent external relay devices
• Channel range = 1-8
• Each relay can switch up to 24 VDC or 28 VAC @ 1 A
• Two 8-pin 3.5 mm mini-Phoenix (female) connectors provide relay termination
Digital I/O
(Port 17):
8-channel binary I/O port for contact closure with each input being capable of voltage
sensing. Input format is software selectable with interactive power sensing for IR ports.
IR/Serial
(Ports 9 - 16):
8 IR/Serial control ports support high-frequency carriers of up to 1.142 MHz with each
output being capable of two electrical formats: IR or Serial.
• 8 IR/Serial data signals can be generated simultaneously.
• IR ports support data mode (at limited baud rates and wiring distances).
