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 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. Refer to the SCS-101 Installation Guide (LT-0320).

Installing the SCS-101
Slide the SCS-101 into the desired modem rack line card slot with the card puller in the up position, as shown in the figure above. Connect the 10-position flat cable from the SCS-150. The light brown (pin 1) wire of the flat cable connector must face up on the line card. Connect the IP network cable. Maximum line impedance is 100 Ohms.
For ULC Medium to Very High Risk Commercial Burglar Applications
The SCS-101 Network Line Card installed in the SCS-1R Receiver must have the ACK Substitution Message programmed as NO.
Communication
The SCS-101 automatically communicates UDP or TCP with DMP panels, iCOM-E™ Encrypted Network Alarm Routers, iCOM™ Network Alarm Routers, and iCOMSL Network Alarm Communicators.
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:
TXD | Transmit Data | RXD | Receive Data |
RTS | Ready To Send | CTS | Clear To Send |
DTR | Data Terminal Ready | TXC | *Transmit Clock |
RXC | *Receive Clock | | |
* 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 #2 and Receive Data (RXD) on pin #3.
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.
