Installation
This step-by-step procedure for installing the E-969 is intended for use by a qualified radio technician.
1. Inspect the E-969 for any physical damage.
2. Look at the rear panel. From left to right are the following:
DTMF output level adjustment.
Microphone input jack.
Microphone level adjustment.
Input/output connector J4.
RS-485 connector.
RS-232 connector.
AC/DC wall adaptor power input plug.
3. Make the transceiver connections at J4, pins 1 through 6. Channel Grant applies to trunking
systems only. Note that there may be more than one wire per Ground input, depending on the use
of the inputs. The pinouts are as follows:
Pin Signal
1 Push To Talk Output
2 Push To Talk Output
3 Audio Output
4 Audio Output
5 Squelch In Input
6 Ground
7 Channel Grant Input
8 Remote Input 1 Input
9 Ground
10 Remote Input 2 Input
4. The Squelch signal and the Channel Grant signal
(Channel Grant is for trunking radio transceiver
only) may be active high or active low. The active
states must be set by two jumpers inside of the
E-969. Remove four Phillips Head screws from
the bottom of the unit to access the circuit board.
Determine the active state of the radio
transceiver Squelch signal, and the Channel
Grant signal (if applicable) and set the jumpers,
as shown to the right. Place the jumper in the “H”
position for active high or “L” for active low.
Factory settings are active high.
