INSTALLATION

INTRODUCTION

The Digital Network Adapter (DNA200) interfaces an external RS232 or RS422 device to Ring Communications’ Crisis Alert System.

The DNA200 operates on +24 VDC. It can be powered from a fuse in the CB901 or RM5000 central exchange. The recommended cord is the BF640A to connect the DNA200 to the RJ45 network jack, KB171. Cords and

jacks must be ordered separately .

Rear Panel Connectors

J1 - 8 pin (RJ45) Network connections:

Two modular jacks are provided at the rear of the DNA200. Use modular cables with straight through pin configuration only! An 8-pin (RJ45) modular jack (KB171) and cord (BF640A) are required for connection to the

network.

The maximum total network length is 7000 feet. A unshielded twisted pair cable should be used for the dat a pair (24 or 22 A WG). Connect the DA T A pair from the network to pins 3 and 6 of the RJ45 wall jack maint aining polarity of the pair . If a remote power source is being used, the negative side of the supply must be referenced to Earth Ground, as well as, the CB901 power supply .

DNA200 OPERATIONS MANUAL

J2 - 9 pin (DB9) RS232 signals :

The DNA200 has a RS232 serial port interface, J2, that can connect to a terminal, printer, or video switcher . Check your terminal, printer or video switcher manual for the correct RS232 connector type, input, output and handshaking signal connections.

The maximum length for a RS232 cable connecting the DNA200 and other equipment is 50 feet. A null-modem (LapLink) cable can be used to connect a DNA200 and a PC computer together if they are close

enough to each other. If you are going to make your own cable the following is a description of the pinout of the DB9 connector on the

DNA200.

J3 - 6 pin (RJ11) RS422 signals :

2008/05/01

A two twisted pair installation utilizing RS422 signals can be used to connect two devices up to 7000 feet apart. A strap MUST be inst alled between RTS and CTS of J2 (DB9), in order to disable flow control for the RS422. To

do this, simply place a strap between pin 7 and pin 8 of J2. You could also solder this strap to a female DB9 connector with solder lugs on the rear, then insert it into the J2 connector.

Flow Control

Hardware flow control is used (RTS/CTS). The DNA200 will send data only if CTS is high (LED on) from the connected device. Parity , Data Bits and S top Bits are programmable (see configuration section).

Resetting Battery Ram

When the system is first installed the Battery Ram must be reset . Procedure:

1. Set all 8 dip switches in SW2 to OFF.

2. Push and release the Reset Switch (SW1).

3. Wait for the Master LED to start blinking (indicates reset complete)

4. Set Network Address.

5. Push and release the Reset Switch (SW1).

Setting Network Addr ess

DIP switch SW2 is used to set the address of the DNA200. See SETTING NETWORK ADDRESS in the NETWORK manual for a full description for setting the addresses.

CALL NUMBERS

All intercom stations are assigned call numbers in the Ring intercom central exchange.

The DNA200 Camera Switcher interface assigns Monitor Address and Camera Address to the intercom call numbers. This assignment is stored in the DNA200 and may bel listed with the command LCN from the PC connected to the DNA100. The call number may be 2,3 or 4 digit decimal. The camera and monitor address may be 1,2 3 or 4 digit HEX. The camera or monitor may be removed from a call number by entering 0 as the address.
