Note.
For the Repeater Enable functions, if the switch is ON and the channel is programmed
as a repeater channel (using MxTools) the SB2025 will act as a repeater. If the switch
is OFF the SB2025 will remain in full duplex mode even if the channel is programmed
as a repeater. The Simplex Enable operates in a similar way.

Select Operating Channel
The SB2025 has a channel capacity of 255. The RF and Continuous Tone Coded Sub-audible
Squelch (CTCSS) frequencies for each channel are programmed using the MxTools Channel
Information screen. There are two ways of selecting the operating channel.

DIP Switch 8-way. DIP switch SW1 provides a binary channel selection facility. When a
switch is ON it is read as a logical 1. When all switches are off the software channel select
mode is enabled.

3.2.2.4
Configure Alarms/M Lead
The SB2025 has three open collector outputs. Two of these are assigned as alarm outputs and
one (Output 1) may be configured as either an alarm output or an M Lead output. However,
Output 1 should be configured as an M Lead, this line is active when mute is open and
CTCSS/DCS (Digital Coded Squelch) is decoded. These outputs are assigned on the
Configuration screen of MxTools.

Configure Digital I/O
The SB2025 has 16 digital Input/Output (I/Os). These are configured using the ET.
