INTRODUCTION
The Digital Network Adapter (DNA100) interfaces an external RS232 or RS422 device to Ring Communications' Crisis Alert System. By setting DIP switches, the DNA100 can be selected to drive these devices:
Termina:l
The external device may be a VT100 Terminal or a PC with VT100 emulation software. The DNA100 is used to configure the following devices:
DXC901 Exchange controller for CB901 DXC910 Exchange controller for CB910/RM5K DNA200 Video switcher DNA300 Input Output Module
DNA400 Pocket page interface
A menu of options on the terminal also allow the user to set the Time/Date, List devices connected to the Crises Alert Network ,View Errors on network, and Monitor network data traffic. The terminal may also be used as an annunciator display. (see M ENU SYSTEM OPERATION).
Printer:
Provides an event activity log of all annunciation and event handling with time/date stamp (see ACTIVITY LOG PRINTER).
The DNA100 operates on +24 VDC (+12, -12 VDC). It can be powered from a spare fuse in the CB901 central exchange or can be powered locally by a separate 24 VDC regulated power supply.
The recommended cord is the BF640A to connect the DNA100 to the RJ45 network jack, KB171. Cords and jacks must be ordered separately.

INSTALLATION
Each DNA100 in a system can be individually powered from a fuse in the CB901 or a local power supply operating off 24V regulated DC.
Figure C1 - Rear Panel Connectors
J1 - 8 pin (RJ45) Network connections :
Two modular jacks are provided at the rear of the DNA100. See Figure C1 . 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.
PIN# - DESIGNATION 1 - No connection. 2 - +12 VDC power input 3 - Data + (positive) 4 - No connection. 5 - No connection. 6 - Data - (negative) 7 - -12 VDC power input 8 - External Alarm.
The maximum total network length is 7000 feet. A unshielded twisted pair cable should be used for the data pair (24 or 22 AWG).

Connect the DATA pair from the network to pins 3 and 6 of the RJ45 wall jack maintaining 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.
J2 - 9 pin (DB9) RS232 signals :
The DNA100 has a RS232 serial port interface, J2, that can connect to a terminal or printer. 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 DNA100 and other equipment is 50 feet.
A null-modem (LapLink) cable can be used to connect a DNA100 and a laptop or 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 DNA100.
J2 SIGNAL
PIN# NAME
1 DCD 2 RXD 3 TXD 4 DTR 5 GND Signal Ground. 6 DSR Not used. 7 RTS Request to Send, output. 8 CTS Clear to Send, input. 9 RI Not used.
DIRECTION/ DESIGNATION
Data Carrier Detect, input. Receive Data, input. Transmit Data, output. Data Terminal Ready, output.

J3 - 6 pin (RJ11) RS422 signals :
A two twisted pair installation utilizing RS422 signals can be used to connect two bridges up to 7000 feet apart.
Use a six wire RJ11 cord with straight through wiring from J3 to another RJ11 jack on both sides of the installation, and then use two twisted pairs between the two RJ11 jacks as shown in Figure C2.
A strap MUST be installed 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. Figure C2 illustrates the strapping of J2.

Setting Baud Rate / Selecting Device Type (For switch locations see Figure C3.)
DIP switches SW3-1 through SW3-6 are used to set the desired baud rate for the RS232 device. SW3-7 and SW3-8 are used to select the RS232 device the DNA100 is driving (see chart below).
BAUD
RATE
1 2 3 4 5 6 7 8
19200 1 0 0 0 0 1 Terminal 0 0
9600 1 0 0 0 1 0 0 = off Printer 0 1 4800 0 1 0 0 0 1 1 = on Not used 1 0 2400 0 1 0 0 1 0 Not used 1 1 1200 1 0 0 0 1 1
Note! The Video switcher software is moved to DNA200 The I/O Module software is moved to DNA300

Communication Protocols
Aside from the baud rate, the terminal emulation should be set for VT100. The DNA100 has No Parity, 8 Data Bits, and 1 Stop Bit.
Hardware flow control is used (RTS/CTS). The DNA100 will send data only if CTS is high from the other device.
Compatible emulation software:
Procomm Plus Terminal for Windows 3.11 Hyper Terminal for Windows 95/98
Set software flow control to OFF and hardware flow control to ON. Set Pace character to >
