128 IconMaster Installation and Configuration Manual
Chapter 5: Connecting an IconMaster to an EAS Device
Communication Protocols
The IconLogo currently supports three communication protocols employed by
EAS devices: TFT
1
, Sage
2
, and Gorman-Redlich (GR)
3
.
RS-232 Connection
The EAS device is connected to the RS-232-D port on the IconMaster
ICONM-BO-V breakout module. See Table 2-7 on page 50 for pinout details. If
the IconMaster ICONM-BO-V breakout module is not being used, the EAS
device must be wired directly to the Multi-Function I/O connector on the
MKE-3901-BM (see Figure 2-25 on page 38). Pins 57 (RS-232-D-RX) and 58
(RS-232-D-TX) are reserved for this purpose. See Table 2-2 on page 39. (One
ground connection is also required.)
Configuring the EAS Device
For basic configurations and preparations please see the specific EAS device
user manual. No additional special settings are needed to communicate with an
IconMaster. The standard signal will be taken out from the EAS device’s serial
port.
IconMaster can be configured two different ways when using IconMaster's
Audio Over to insert the EAS audio message into the program stream.
An important consideration is that the EAS audio message is not always the
same duration as the EAS logo message.
Method 1 (preferred): IconMaster controls EAS logo insertion and EAS audio insertion
separately.
1. Configure the EAS receiver to output a GPI output for the duration of the
audio message.
