Product Manual
Sea Air and Land Communications Ltd, 10 Vanadium Place, Addington, Christchurch 8024, New Zealand
February 2019
Commands
The outputs of the 12-84-7000 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 12-34 output module(s) can be connected for simple control
of any number of relay outputs.
