Product Overview
The 12-34 is a low cost scalable relay output solution. Each 12-34 can allow 4 relays to be
controlled using the Salcom relay control protocol. The 12-34 can be daisy chained to allow
any number of relays to be controlled.
A green and red LED display operational status, a chart displaying status codes can be found
in section 4 - Connections. A 12-terminal connector is used to bring all connections from the 4
relays out. The relays are not mains rated.
Programming software is not required for this product. On startup, the firmware version number,
monoshot timer settings and unit ID are displayed, and can be changed.
The relay unit connects directly to a 12-84 receiver or PC serial port without any special
configuration requirements. The 12-84 can be configured to send all relay control packets
down the serial port to all other units.

Configuration
Figure 3. Connecting a 12-34 to a PC for configuration
The 12-34 does not require the use of configuration software, it can be set from a terminal
(9600,N,8,1). Configurable items are:
•Monoshot time for each relay
•Unit ID
On startup the 12-34 will respond with
“SALCOM 12-34-0000 Unit ID:XX”
“Relay 1 Monoshot time: 0 (Latched)”
“Relay 2 Monoshot time: 0 (Latched)”
“Relay 3 Monoshot time: 0 (Latched)”
“Relay 4 Monoshot time: 0 (Latched)”
“Enter ### to configure”
When in configuration Mode the 12-34 will respond with:
“SALCOM 12-34-0000 Configuration”
“(1) To set Relay 1 monoshot time”

“(2) To set Relay 2 monoshot time”
“(3) To set Relay 3 monoshot time”
“(4) To set Relay 4 monoshot time”
“(5) To set unit ID”
When setting relay times the 12-34 will respond with:
“Relay 1: Enter time in mS (0 = Latched, Max 1800000)”
When setting unit ID the 12-34 will respond with:
“Unit ID: Enter unit ID (0-99)”

Operation
After startup the unit parameters are displayed, and unit is able to be configured.
Configuration mode can only be entered within 20 seconds of startup, or within 20 seconds of
the last configuration item change. This is to prevent accidental configuration changes.
Reception of a relay control packet within the startup period will result in the 12-34 immediately
exiting config mode.
The green LED shows unit operational status –flashes when ready and idle. The red LED flashes
upon error, or is held steady on for at least one second upon reception of any command valid
for that unit.
The green LED is also held steady on for at least one second when there is a valid command for
ANY unit, allowing a daisy-chained arrangement to be easily inspected.

Relay Operation
Relays are controlled using Salcom relay control protocol –see (Relay Control Protocol below).
The 12-34 will tolerate 12-84 protocol, looking for the relay control protocol payload embedded
in the string. The 12-34 will tolerate the relay control protocol being embedded anywhere within
a string, so will cope with messages like “Main Door Open 01109” or “02112378987 01109”.
In the case of complex numeric messages the 12-34 will act on the first instance where a valid
relay control protocol is matched for that unit ID. Commands are not buffered within the 12-34,
simply inspecting the contents of the serial string, and passing the message immediately on
again to be processed again by the next 12-34 in the system.
Relay Control Protocol
Relay commands take the form IIC0X9 where:
II is the 2 character unit ID, C is a variable number of relays to close (up to 4). 0 marks the end of
relays to open, X is a variable length list of relays to close (up to 4). Commands are always
terminated by a 9. A red LED will display on the PCB showing which relay is closed.

e.g.
23109 Will only address a unit with matching ID 23.
Relay 1 will be closed. No other action taken.
231209 Will close relay 1 and 2 on a unit with the ID of 23.
230129 Will open relay 1 and 2 on a unit with the ID of 23.
23012349 Will open relay 1,2,3 & 4 on a unit with the ID of 23
