Model SCS-101 Network Interface Card
Description
The SCS-101 Network Interface Card provides for a connection from a digital data network to a port on the
SCS-1R Receiver. Each card includes one 10-position, 6-inch flat cable for processor card connection, and one
eight-pin modular connector for digital data network connection. This allows the SCS-1R Receiver to accept alarm
and system messages over a network from DMP Command Processor panels. For optimum performance, install the
SCS-101 card in the SCS-1R Receiver line card slot 5. Refer to the SCS-101 Installation Guide (LT-0320).

Installing the SCS-101
Slide the SCS-101 into the modem rack line card slot 5 with the card puller in the up position, as shown in the
figures above. Connect the 10-position flat cable between the SCS-101 Network Interface Card and the SCS-1062
Processor Card. Connect the IP network cable. Maximum line impedence is 100 Ohms. The network connection is
power limited and supervised for fire communicating accounts.
Communication
The SCS-101 automatically communicates UDP or TCP with DMP XR500 Series and XR2500F Command Processor™
panels, iCOM-E™ Encrypted Network Alarm Routers, iCOM™ Network Alarm Routers, and iCOM
SL
Network Alarm
Communicators.
Important Compatibility Information
The SCS-101 line card Level E Version 200 or higher can ONLY be used with SCS-1R Receivers with firmware
Version 903 or higher and is NOT compatible with the SCS-1 Receiver.
The SCS-101 line card Level D Version 103 or lower can ONLY be used with the SCS-1R Version 902 or lower
or SCS-1 Receivers.
LED Indicators
The seven bi-color LEDs indicate the network interface card condition during various stages of communication.
A description of each LED is listed below:

* If the clock signal is present, both red and green segments of the LEDs light.
SCS-101 Data Jumper Settings
The SCS-101 data jumpers are pre-configured for NET at the factory.
RXD and TXD
The factory setting is Transmit Data (TXD) on pin #3 and Receive Data (RXD) on pin #2.
FORCE CTS
The jumpers are set vertically as the factory default. This allows the SCS-101 to tie the CTS and RTS data lines
together.
