Installation and Connections
Situate the 12-8 away from direct sunlight, vibration and strong heat sources and avoid close
proximity to radio transmission equipment. The unit is not certified as intrinsically safe.
In good coverage areas fit the aerial directly to the aerial socket. An external aerial may be
needed where reception is poor.
Connect a 12 volt DC power supply to the power terminals (see figure 1). The 12-8 is protected
against reversed supply connection. The power source must be reasonably noise free.
Relays are not to be connected directly to mains voltages. Open collector outputs are best
suited to drive external relays, as indicators or to drive inputs that have moderate to low current
requirements.

Operation
The unit receives and decodes a numeric or alphanumeric pager call. If the received unit
number matches the 12-8 unit number or group number, the outputs are switched according
to the ON/OFF fields of the message.
Correct Operation
Normal operation of the unit is indicated by the green system LED flashing. If the LED does not
light, check the voltage on the supply terminal block.
During the reception of a valid command with the correct RIC code, the system LED will stay on
for approximately one second.
Unit Number
Each unit will respond only to messages containing a matching Unit Number. Up to 99 unique
unit numbers are available. Any number of units can be programmed with the same unit number.
The Unit Number comprising of 2 digits is selected using the configuration software.
Monoshot
Output mono-shot (momentary) operation can be enabled by using the configuration software.
Each output can have its own mono-shot time, ranging from 25mS to 30 minutes in 25mS steps.
Setting the value to 0 disables the mono-shot timer altogether, and the output is latched until
commanded off.

Commands
The outputs of the 12-8 -7000 are controlled by a series of numeric commands sent in the form
of a numeric or alphanumeric pager message. Note: Control strings can be sent as numeric or
alpha-numeric messages. Numeric messages are shorter, and are therefore more efficient to
transmit.
The control string can be embedded anywhere within the message e.g. “TEST MESSAGE 01109”.
Multiple control strings can be present in the message if desired. E.g. “PUMP ON 01209 23209”. By
allowing multiple control strings, a 12-3 output module(s) can be connected for simple control
of any number of relay outputs.
Command Format:
UUx..x0y..y9
UU Unit number:
This must be entered as 2 digits 00 - 99.
x Output to go ON:
This digit can be 1- (represents output). Any combination of digits 1- before the
‘0’ can be entered in any order. If no digits are entered before the ‘0’ then no
outputs are turned on.
0End entry of Output ON values:
This terminates the list of outputs to turn on. This character in mandatory.
y Output to go OFF:
As per “Output to go ON” above, but this designates the output to go OFF instead.
9 End entry of Outputs OFF values:
This terminates the list of outputs to turn OFF. This terminating digit is required to
consider this as a valid control string

Programming
Preparing to Use the Programming Software
To change the field programmable options, the unit must be connected to a PC using Windows
XP or later, running the 12-8 PSD programming software, downloadable from Salcom’s website
http://www.salcom.com/media/software/Salcom-12-8 SE-PSD-v101 .zip
Connection should be from the serial port S2 on
the 12-8 to a com port on the PC.
To make this connection Salcom’s serial
programming cable, part number 12- 5-0000, as
shown below, can be used.
Where the PC only has USB ports a DB9 to USB adaptor can be
used (not supplied by Salcom).
Note: If you do not have a serial cable you can make one with the S2 connections as shown in
the section Connectors and Pin-outs in this document.
Once the cables are correctly connected apply power to the 12-8 .

Using the Programming Software
The 12-8 PSD allows the user to configure the following characteristics:
•Unit IDs
•Receive frequency configurations
•Output Hold Times and Busy Mode
•RIC receiving parameters
Use the mouse to select the configuration fields for each feature, which you want to change and
then select ‘Program’ to update your 12-8 ’s configuration.
Note: After programming the 2-84 you must select “Disconnect” for the changes to take affect
and for the 2-84 to return to its normal operational state.
D: 2-character id which identifies this unit when the 12-8 relay protocol is used. Valid settings
are ”00” to ”99”.
Decode any R C: When “Selected” all messages are to be decoded and sent to serial port.
Messages, if not defined within a range are assumed to be alphanumeric.
When “Not Selected”, default, the receiver will only decode messages within valid ranges (not
beginning with 0000000) or using the POCSAG Rapid Relay control RIC.
Vehicle D: Is a feature that allows the setting of an ID from “0000” to “9999”. The “Vehicle Id”
precedes the Unit id in the received message e.g.
oFormat: VVVVSIIC0X9<CR> where:
VVVV is the -character Vehicle Id
II is the 2-character Unit Id
S is a space
C is a variable number of relays to close (1-8)
0 marks the end of relays to close
X is a variable length list of relays to open (1-8)
9 marks the end of relays to open
oTypical Usage: 0123 011029<CR> where Vehicle Id is 0 23, Unit Id is 0 , relay is
closed and relay 2 is opened.
Default Freq: When using Vehicle Id, up to 3 frequencies can be pre-defined using the
programming tool for use with this feature. Valid settings are ”1”, “2” and ”3”.

12-8 -7000 RELAY OUTPUT RECEIVER Product Manual
Sea Air and Land Communications Ltd, 10 Vanadium Place, Addington, Christchurch 802 , New Zealand February 2019
Frequency Configuration: Under normal operation a single frequency is defined for use with your
12-8 . When a Vehicle ID value other than “0” is set up to 3 pre-defined frequencies can be set.
The frequency setting consists of 3 parameters:
Rx Frequency: The frequency to set receiver to.
Frequency Minimum Maximum
VHF 1 8.0000 161.0000
UHF 50.0000 70.0000
Note: The selected frequency must be evenly divisible by the channel spacing.
Note: With the VHF version of the 2-84 there is only moderate adjustment (within
approximately +/-3MHz) that can be made from the factory preset receiver frequency,
before your unit may become unstable and unable to receive a useable signal.
Ref Frequency: This defines the channel spacing that the 12-8 is using. Available settings
are ”5kHz” default or ”6.25kHz” baud.
Rx Baud: Changing this setting will allow messages to be received at the selected baud
rate. Available settings are ”512” default or ”1200” baud.
Pocsag Rapid: When “Selected”, if a message with a RIC that matches the POCSAG Rapid >
Relay Control RIC is received, then the message is decoded and the relay control action is
undertaken.
Note: Decoded messages matched to the Relay control RIC are not sent out the serial port.
R C: The POCSAG Rapid control RIC to be matched. This RIC also includes the 7 RIC codes
following the one specified. Valid RIC values are between 8 and 2000000.
Decode: The expected format for the message to be decoded from. Available options are
‘Alpha Numeric” or “Numeric”.

Sea Air and Land Communications Ltd, 10 Vanadium Place, Addington, Christchurch 802 , New Zealand February 2019
Output Hold Times: For each of the 4 outputs (1, 2, 3 and 4) it sets the time for that output to stay
on after it has been turned on.
If an output hold time is set, an output when turned on will turn off again after the Hold Time (in
ms) has elapsed.
Setting Description Hold Time
0 Output will stay on until instructed to turn off (default) Indefinite
1 Minimum Hold Time 1ms
1,800,000 Maximum Hold Time 30mins
1 Step size = 1ms
Note: If POCSAG Rapid is used, then for reliable operation, this Hold Time should not be less than
50ms (otherwise the relays may chatter).
Busy Mode: Defines the behaviour when “Busy” and consists of parameters:
Busy Output: The output to close when the receiver channel is busy.
Setting Description
0 Disable the “Busy Output” feature (default)
1, 2, 3 & Busy output to operate in preference over any other
output control operations.
Level: This is the received signal strength that must be exceeded in order to close the
configured busy output. The level is configured in dBm.
Setting Description
- 0dBm Minimum busy level to be exceeded
-125dBm Maximum busy level to be exceeded
-80dBm Default busy level to be exceeded

Sea Air and Land Communications Ltd, 10 Vanadium Place, Addington, Christchurch 802 , New Zealand February 2019
Debounce: How long the channel must exceed the configured “Level” before operating
the configured output.
Setting Description
0 No debounce (default)
1 Minimum debounce time (25ms)
0 1 second debounce time
255 Maximum debounce time (6s)
1 Step Size = 25ms
Busy on Decode: If this option is “Selected” and a busy output has been set, then the busy
output will operate when decoding any POCSAG message regardless of the received
signal strength. When “Selected”, the busy output will continue to operate when the busy
level has been exceeded.
Receive Ranges: Describes ranges of RICs that should be managed in a similar fashion. To disable
a range, set the first RIC in the range to 0000000.
Min R C: The RIC code between 8 and 2000000 that identifies the beginning of the range.
Max RIC: The RIC code between 8 and 2000000 that identifies the end of the range. Max
RIC may be the same as the min RIC, but may not be less than the min RIC.
Decode: Decode Describes how the messages matched in this range will be decoded.
Available values “Alpha Numeric” or “Numeric”.
Monitor Action: If a RIC is matched in this Range this action will be performed, either “None
(no action)”, ”Close Relay 1” or ”Close Relay 2”.
Note: this type of relay control is more vulnerable to false triggering than using the relay
control protocol. This should not be used for general relay control, using the relay control
protocol is the preferred method.
