INTRODUCTION
The On The Air Light (OTAL) system allows Carrier Operated Relay (COR) signals from remote receivers to
drive On The Air Lamps at consoles. It provides a jumper-selectable option to add Push To Talk (PTT)
qualifier(s) to the COR signals so that the console light displays only when the console is keyed and a carrier is
received at the receiver.
The OTAL system uses standard modules from the MCN (Monitoring and Control Network) to transport the
remote signals. It also uses an OTAL Driver Assembly. This manual covers the OTAL Driver Assembly and
overall OTAL system overview.
The OTAL Driver Assembly is available in two different versions according to the following table:
Part Number Description
S1-61030
S1-61121
Figure 1 shows a typical OTAL system. It includes the optional Remote PTT circuitry. The Remote PTT and
Remote COR signals connect to remote CIB modules. The data from the remote CIB modules is sent via EXB
Network Extenders to the IIB modules in the OTAL Driver Assembly.

Figure 1 - Typical OTAL System
Remote requirements to transport the COR and PTT signals vary by system. EXB modules are shown that
utilize 2W/4W leased lines. Other EXB modules are available that use copper or fiber Ethernet, or RS232
channels.

• Accepts (8) local PTT inputs
• Accepts (8) remote PTT inputs via MCN network
(optional – S1-61030 only)
• Powered by 100-140 VAC input
• Optional 12 VDC input
• Generates (8) On The Air Light (OTAL) Outputs
• Jumper selectable OTAL Logic:
- COR only OTAL
- COR + PTT OTAL
• Keyup Failure Alarm (when PTT is used)
• Link Status (for both IIB modules)
• Power supply status (for both power inputs)
• OTAL and alarm status outputs (via MCN Network) for display on PCs

OTAL DRIVER LOGIC
The OTAL Driver Assembly features two types of OTAL logic, depending on jumper settings selected:
• COR + PTT OTAL Logic
(Enabled with E4 & E10 jumpers OUT)
• COR Only OTAL Logic
(Enabled with E4 & E10 jumpers IN)
COR AND PTT OTAL DRIVER LOGIC
Output Logic
OTAL Out = (Local PTT OR Remote PTT) AND COR
Keyup Fail Output Logic
The Keyup Fail signal is derived from the PTT signals and the COR signals. If a PTT is active and there is no
COR within a fixed time (typically 1 second), the Keyup Fail will become active. The time delay allows for
tone keying, keyup delay, and COR delay. The Keyup Fail feeds the Status CIB and can be indicated on the
MCN PC.
Keyup Fail Alarm = (Local PTT OR Remote PTT) AND NOT COR
COR ONLY OTAL DRIVER LOGIC
The COR Only logic is as follows:
OTAL Output = COR
Keyup Alarm = not applicable (PTT signals are not used in the OTAL logi c)
OTAL Logic 8

FIELD CONNECTIONS
LOCAL PTT CONNECTIONS
Local PTT signals are connected to J1 of the OTAL Driver PCB. (PTT inputs are not required if COR Only
OTAL Logic is used.)
Local PTT signals shall be either:
Isolated Form A Relay Contacts (or opto-isolated relay outputs)
closed when PTT signal is present.
Logic Outputs - Negative Ground, Active Low when PTT is active.
They must be capable of:
Up to +20 VDC Open Circuit
Sinking a minimum of 30 mA when active
Maximum of 0.2 V when active
Signals must not drive other equipment.
The Local PTT signals appear on the first 8 pairs of J1 as follows:

(The “A” suffix on the PTT signals indicates the Local PTT.)
The ground signals are tied together on the OTAL Driver board. It is preferred that the PTT signals be wired to
J1 as pairs, with separate grounds.

MODULE ADDRESSING
The MCN Modules in the OTAL system must be addressed properly: Some requirements for addressing are:
All MCN modules must be uniquely addressed; no two modules may be set to the same
Group & Module address.
There may be restrictions on what MCN Group numbers may be used in a particular part of a
large network. If you have a Custom Engineered System, follow the addressing set for each
module as specified in your system documentation.
IIB modules must have two addresses set: first, the address of the CIB module it talks to and
second, its own address. The PTT IIB (if used) will talk to the PTT CIB. The COR IIB will
talk to the COR CIB.
IIB DUAL ADDRESSING
Use the following steps to set up the addressing of the IIB:
1. Set Option Switch 4 Up.
2. Set the Group & Module hex rotary switches to the address of the CIB that the IIB will talk to.
3. Press the Reset button. The Reset LED will blink and then come on solid.
4. Set Option Switch 4 Down.
5. Set the Group & Module hex rotary switches to the IIB’s own address
6. Press the Reset button. The reset LED will go out.

• The channel names can be customized in the MCN Config program.
• The status of the power, along with the status of the CIB Links are shown above each group of 8 channels.
• Channel 2 shows a channel that is normally keyed using the Main PTT. The COR signal is active and the
OTAL Driver Assembly is generating an OTAL signal.
• Channel 4 shows a channel with normal keying using the Remote PTT.
• Channels 6-8 show receive traffic. Since there are no PTT signals (and the system is using COR + PTT OTAL
Logic), the OTAL lights are off.
• Channel 10 shows an abnormal situation. The Main PTT signal is active, but there is no received signal and
therefore, no OTAL light. This could be caused by any number of problems, inclu ding a bad transmitter, bad
phone line, or a bad receiver.
• Channel 12 shows a similar abnormal situation, but with an attempted transmission using the Remote PTT.
