RS-232 Ports Connections

Three RS-232 ports are provided on the rear panel of the

AD2150 for control connections (Figure 1-1, page 1-3). RS-

232 keyboards, AD2096 Alarm Interface Units, external

computers, and other RS-232 compatible devices are

connected to any of these ports. Four keyboards can be

connected to any control port using AD1981 Port Expanders.

The use of each port must be defined via the PORT menu, page

4-15, for the type of device connected.

Three modular cables (JJ0007) and three 8-pin Terminal Boxes

(HP0047, Figure 1-2) are supplied for RS-232 connections. If

the connection distance between the AD2150 and the RS-232

device is 7 feet or less, connect the RS-232 port directly to the

RS-232 device using the supplied modular cable (JJ0007).

If the connection distance exceeds 7 feet, use the Terminal Box

(HP0047) for RS-232 connections. Connect the Terminal Box

to the RS-232 port of the AD2150 using the modular cable

(JJ0007). The pin definitions of the HP0047 Terminal Box are

shown in Table 3 below.

Note: All American Dynamics keyboards are supplied with a

separate power supply and Terminal Box for RS-232

connections. See the appropriate keyboard manual for these

connections.

For proper RS-232 communication, both the pin definitions

and the EIA Standard DTE or DCE designation of each

equipment must be observed. The AD2150, as with all

American Dynamics equipment, is configured as a DTE

device. For DTE-to-DTE communications between an RS-232

device and the AD2150 HP0047 Terminal Box:

- Connect the XMIT pin of the RS-232 device to RCD (pin

4) of the AD2150 Terminal Box.

- Connect the RCD pin of the RS-232 device to XMIT (pin

5) of the AD2150 Terminal Box.

- Connect the Ground pin of the RS-232 device to GND

(pin 7) of the AD2150 Terminal Box.

RS-232 cable shield connections are made at the connectors of

the RS-232 port or modem only.

The maximum cable length between an RS-232 device and the

HP0047 Terminal Box is 1000 feet, using 18-AWG shielded

cable (Belden 8770 or equivalent). For distances of over 1000

feet, a link using either asynchronous line drivers over

dedicated cables, short-haul modems over dedicated phone

lines, or dial-up modems is required.

Refer to the Appendix for typical RS-232 system connections.

Alarm Connections

A 16-pin connector labeled “ALARMS RELAY” is provided

on the AD2150 rear panel (see Figure 1-1, page 1-3). This

connector provides eight alarm contact inputs and an external

sync input, and access to an internal relay activated by alarms.

A mating 16-pin screw-terminal connector is provided.

ALARMS - Inputs to the ALARMS connections 1 thru 8,

from user-supplied alarm contacts/devices, activate the

AD2150 alarm functions. Closures must have a resistance

of 500 ohms or less. Connect the alarm contacts to Alarm

Inputs 1 thru 8; connect alarm contact returns to Ground

(pin 1 or 10) of the ALARMS connector.

Note: Model AD2096A Alarm Interface Unit inputs

provide an additional 120 alarm contacts (9 - 128), see page

4-10.

EXT SYNC - Input is provided for external frequency

synchronization of the AD2150. The external sync input

signal must be 1 - 5 Volts RMS, 50/60 Hz.

RELAY - Form-C alarm RELAY connections are provided on

the rear panel: Normally Open and Normally Closed. This

relay activates during alarms for control of a VCR or other

alarm response device. The contact ratings are: 0.6 Amps

@ 24 VAC or 2.0 Amps @ 30 VDC.
