This Application Note provides information on how to connect multiple
TB8100 base stations to a Service Kit or Alarm Center using an
Asynchronous Port Switch (APS). It covers connection via direct serial link,
and via PSTN lines using modems. Typical physical connections, APS
configurations, base station configurations, Service Kit configurations, and
modem settings are also described.
1 The Purpose of an APS
One of the most powerful features of the TB8100 base station is its ability
to be remotely configured and monitored. This feature includes Service Kit
access, for remote configuration, monitoring, and diagnostics, and
automatic dial-out to an Alarm Center, as a result of an error condition or
Task Manager stimulus. TN-742 describes the use of this feature in detail.
Without using an APS, however, a dedicated PSTN line is required for each
base station installed on a site. The cost of these lines is very high, especially
when the base stations are installed in remote locations. Using an APS
allows a single phone line to service up to 31 base stations.
A typical connection scenario is shown in Figure 1 below. The diagram
shows:
■four base stations connected to various ports on an APS
■the dial-up modem at the remote site
■the PSTN connection
■the modem at the local site
■a PC running either Service Kit or Alarm Center software.

2 Supported APS Units and their Main Features
2.1 Units Supported
The APS support feature in the TB8100 base station is intended to work
with third party products. Tait Electronics Limited does not manufacture its
own unit. The following third party units are supported:
■Western Telematic Inc. (WTI) APS-8, APS-16, CMS-16, and CMS-32.
■Black Box SW543A.
Any other APS that uses simple ASCII connect and disconnect commands
and responses may work satisfactorily.
2.2 Main Features
These features are standard on the supported APS units listed above.
■You can connect up to 7, 15, or 31 base stations per site to a single PSTN
line or PC, depending on the APS chosen.
■The units are configured as DTE (Data Terminal Equipment).
■The units will support all baud rates recognised by the base station, i.e.
1200, 2400, 9600, 19200, 38400, 57600, and 115200.
■Although the APS ports can be individually configured, and may be
password protected, the TB8100 base station does not support this.
(Note that in “Common Configuration for all Ports” on page 14 the
password is left undefined)
■The APS configurations are stored in non-volatile memory.
■Data clashes are prevented using a Busy response, i.e. if one base station
tries to dial out while another is connected, it will receive a Busy
response, and can try again later if configured to do so.
■The Service Kit or base station alarm dial-out software handle all
common errors such as busy, lack of response, or communications failure.
■The APS can be powered from 115/230VAC or –48VDC (depending
on the model). The power consumption is approximately 5W.

3 Physical Connections
In all the following connection types, only two or three base stations are
shown connected to the APS for graphical convenience.
The modem is shown connected to the highest numbered port of the APS.
This is for user convenience only, and allows an easy mapping between the
base station number and port number when configuring the Service Kit.
Any port could be used if desired.
A single null modem cable is supplied with the APS. The user must supply
all other cables.
Note A 9-way straight-through RS-232 cable is available from Tait
Electronics under the part number 219-02636-00. However, the
connector bodies on this cable are too big to allow one connector
to fit directly above or below another on APS units with 16 or
more channels.

Cables 1, 2 & 3 9-way straight through (not null modem) RS-232 cable
Cable 4 APS power cable, either AC mains or –48VDC, depending on the model chosen
Cable 5 modem power cable, usually AC mains
Cable 6 Telco connection, usually RJ12 (also called RJ11 in some countries)
Notes ■RS-232 connections are made via the control panel at the front of the base station.

Cable 6 modem power cable, usually AC mains
Cable 7 Telco connection, usually RJ12 (also called RJ11 in some countries)
Notes ■The TaitNet RS-232 system interface board is essential if you want remote
diagnostics to both channels in dual channel subracks. It is optional for single
channel subracks.
■Connections to the TaitNet RS-232 system interface board are on the rear panel of
the reciter.
■Front or rear panel connections to single channel subracks can be mixed with rear
panel connections to dual channel subracks, in any combination, on a single APS.
■The TaitNet RS-232 system interface board can be installed by the user, with care
(refer to the TB8100 Service Manual). The reciter firmware will automatically
detect the system interface board type, and route the RS-232 signals appropriately.
■If the TaitNet RS-232 system interface board is fitted, the control panel does not
shut down in Power Saving modes, resulting in a small compromise in power
saving effectiveness.

Notes ■The illustration above shows base stations with TaitNet RS-232 system interface

■If possible, the PC should be connected to a spare APS port so that normal dial-in
and dial-out is not disrupted. If there is no spare port available, any port can be
used, but some disruption may then possibly occur.

3. Set up the parameters in the Connection tab as usual (use the online
Help if required).
4. In the Port Switch tab, select the Port switch check box.
5. In the Connect command field, enter ^M/Cx^M.
This means:
Note Use the ^ (carat) symbol to instruct the Service Kit that this is a
control character. Do not use the control key.
6. In the Connect response field, enter 1.
7. In the Disconnect command field, enter ^Mxxx^M/X^M.
This means:
8. In the Disconnect response field, enter 3.
^M instructs the APS to enter command modea
a. This is equivalent to the carriage return character.
/C requests a connection
x the port number of the base station you wish to connect to
^M terminates the sequence
^M instructs the APS to enter command mode
xxx three instances of the logoff charactera
a. This must match the logoff character chosen when setting up the modem (L
was chosen in this case). Refer to “Common Configuration for all Ports” on
page 14.
^M terminates the sequence
/X^M exits command mode
