Product Overview
The 12-8 -7000 Relay Output Receiver is available in two versions, a VHF 12-8 -7150 and a UHF
12-8 - 7 50 both of which provide four outputs (2 relay and 2 open collector) which can be
controlled remotely via SALCOM transmitters or wide area paging networks.
The unit can also be used as a programmable general purpose channel busy output module.
When used as a channel busy output module, it can also be used on any non-paging channel.
Suitable for site monitoring as network activity is delivered by the serial port of the 12-8 .

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 .
