Section 17. Relay and Control Port Operation
All T
ieline
codecs have two CMOS solid state relays for the control of equipment.
They consist of two relay closures and two opto-isolators and can toggle or pulse.
Relays behave in the same manner for all connection modes.
These two relays have been designated
Control Port 1
and
Port 2
.
They can be
activated by User Function buttons which can be set via the
Functions
menu within
T
ieline Tool Box
software. User Functions are
activated by a sequence of the
F1
or
F2
button
being pressed, followed by a number on the
keypad. To read more about setting up the relay
functions see the
Tool Box
Control
and
Functions
menu sections within this manual.
Figure 34: Control Ports on a Codec
As mentioned,
Control Port 1
and
Control Port 2
relays can be used in two different
modes:
Pulse: When activated the relay will close one second.
Toggle: When activated the relay will toggle, i.e. if the relay is open, it will close.
If closed it will open.
The
Control Port 1
and
2
relay controls are assignable to any combination of
FUNCTIONS
buttons or to one of the four
SOFTKEY
buttons (or
HOTKEY
buttons
on the
COMMANDER
G
3
rack unit codec front panel and TLG3 GUI, or the
i
-
Mix
G 3
) - for faster one button operation. Please see the
Tool Box
Functions
menu
section within this manual about assigning the
SOFTKEY
or
HOTKEY
buttons.
17.1. External Relay Box
Each codec user profile includes a 50 byte per second Remote Control
Channel
14
for remote control of external
T
ieline
devices such as an external relay
box. Up to four
15
external relay boxes, each with eight CMOS relays and eight
input controls can be added to a system via the
CAN
port - this allows up to 32
external relays to be utilized.
CAN is a Multi-Node serial buss to which several
T
ieline
products can be
connected simultaneously each with their own unique ID address. Each opto-
isolated input can be used to trigger a range of user programmable functions and
can be connected to a relay closure or an open collector driver.
A master device can provide power or an external plug pack can be utilised
where there are long cable runs. In addition, depending on the codec in use,
current consumption will limit some products being powered from the buss. In
14
50 bps is the minimum data capability. ISDN, X.21 and IP connections may provide
greater data bandwidth.

Please check with us at support@tieline.com for updates on the implementation of this
feature. Currently only one relay box can be connected.
