The control inputs and outputs of the Linker IIa repeater controller are very simple to use. There are 3 COS inputs,
2 CTCSS inputs and 4 open collector type outputs. The inputs include a Control receiver COS input, the repeater
input (port 1) with COS and CTCSS inputs, and the remote base / link receiver (port 2) also has a COS and a
CTCSS input. All of these COS and CTCSS inputs can be set to switch between 1 and 9 volts and the polarities are
programmable. Both ports 1 and 2 have COS and CTCSS inputs. You may select between the COS and CTCSS or
select both for ‘AND’ or ‘OR’ control. This allows for the switching back and forth between carrier squelch and
CTCSS (need an external CTCSS board (TS-64)) for the ‘receiver active’ signal.
The auxiliary outputs of the Linker IIa are multi featured and easy to use. The 3 auxiliary outputs can be used for
several different functions. All of the 3 auxiliary outputs can send a short pulse or either be locked on or off. The
Auxiliary 1 output has a programmable timer that can be enabled or disabled. It can also control a timed transmitter
fan. The Auxiliary 2 output optionally provides the PTT for the link / remote base transmitter (port 2). The
Auxiliary 3 output can provide control of the remote base memory selection. The 4
th
open collector output is for the
repeater / port 1 push to talk. All of the inputs are buffered and the outputs are protected to greatly reduce any
chance of damage.
