EZTEXT -GSM REMOTE CONTROL
1. Insert Simcard
Please note:
•Insert SIM Card before applying power (standard 3 Volt SIM only).
•The message memory of the SIM card should be clear before it is fitted.
•Ensure that the SIM card has not been PIN Code Protected!
•Beware of Pay-as-you-go SIM which require regular top-up to remain active.
•It is recommended to bar Incoming voice calls to the SIM card to avoid error messages being sent back to the
user. This can be achieved by calling the service provider.
The SIM card should be inserted into EZTEXT before applying power
RF Solutions recommends O2 and Vodaphone SIM card and has carried out extensive testing using the
SIM cards we have for these two networks.
Problems have been identified with Orange SIM cards with this product.
No guarantee can be given for the operation of this product with any network except those that have been
tested by RF Solutions.
2. Connect Inputs / Outputs and Power Connections
The EZTEXT unit can be powered from 9 to 24Vdc.

5. Optional Battery Backup (880mAH Lithium rechargeable)
The battery provides an automatic backup supply to continue normal operation when power fails. EZTEXT
can also send an SMS when power is switched to battery and when main power is restored.
The battery is recharged and maintained when power is present
In the event of a complete power loss, EZTEXT will retain user configured data, however the status of the
relays will be lost.
6. Optional External Antenna
Using an external antenna can provide a much better signal reception than the internal antenna
Unplug the Antenna Connection. Use Cable adaptor CBA-UFLSMA-1 to provide an SMA Bulkhead
connector into which many alternative GSM antennas may connect. Using an external antenna can provide
a much better signal reception than the internal antenna

letters or numbers.
If for any reason the unit password is lost, remove all power for 1 minute, and then
start again.
UPW#1234
(sets password to 1234)
Response:
UPW OK
Unit Identity UID
UNITPW#UID#UNITID
This sets the ‘identity’ of the EZTEXT unit, and will be included in any response text
