CHAPTER 8: REMOTE PROGRAMMING
Overview
Many settings of the CS-540 can be remotely programmed using DTMF tone sequences. You can add and
delete users, as well as modify all individual user settings, such as TX/RX squelch options and courtesy tones.
In addition, many channel settings can be modified remotely as well, such as the broadcast ID interval and
the TX Timeout timer.
Before You Begin
Before you begin using the remote programming features, please go through the following checklist to make
sure that you meet all the requirements for remote programming.
Some basic channel settings, such as the channel ID, remote access PIN, RX/TX frequencies must be
set up by your dealer or by using the PGM-540 programmer.
A four-digit remote access PIN must be entered in order to access the remote program mode. Make
sure that you know the PIN for the channel that you wish to modify before you begin.
You must have a handheld or mobile radio that can generate CTCSS tones / DCS codes and DTMF
tones simultaneously. The handheld or mobile must generate each DTMF tone for at least 40ms and
the duration between DTMF tones must be at least 40 ms.
Every user belongs to a particular “slot”. There are 64 slots, numbered from 0 to 64. Whenever you
modify an individual user’s settings, you must enter their slot number, so make sure that you know
their slot number. Moreover, if you want to add users remotely, you must know which slots are free.
Try to keep an updated list of all the slots and their corresponding users. A blank template is provided
in Appendix D of this manual for this purpose. You can also export a list of users and their settings for
printing using the PGM-540 programmer.
The user is Slot 0 is the designated System Operator. Only the System Operator may remotely
program the CS-540, so make sure that you have a user in Slot 0. The Slot 0 user settings must be
set up by your dealer or by using the PGM-540 programmer.
You’ll want to try to keep remote programming sessions as short as possible. While in remote
programming mode, all other users are locked out of the system, so you’ll want to minimize the
repeater’s downtime. Another consideration to keep in mind is that the repeater will automatically
exit remote programming mode without saving the changes if it doesn’t receive a DTMF tone for 60
seconds. For these reasons, we highly suggest that you right down all the command sequences that
you would like to enter before you begin.
