The Gateway board is an RS485 to RS485 converter.<br />

One side of the Gateway is always connected to the Retail<br />

Solutions I/O Network. The other side of the Gateway is<br />

the receiver bus (RS485). The receiver bus is connected to<br />

one or more RS485 devices depending on which type of<br />

Gateway is being used. The Gateway interfaces devices to<br />

the Einstein/<strong>E2</strong> and legacy Retail Solutions controller<br />

(REFLECS) by simulating 16AI and 8RO boards using<br />

Retail Solutions standard I/O board protocol. The Gateway<br />

can also convert third-party controller protocols to<br />

Retail Solutions protocol for custom cells created in the<br />

Einstein/<strong>E2</strong> to interface with third-party controllers (Danfoss,<br />

Woodley, etc.).<br />

The Gateway performs one of two basic functions:<br />

1. It allows control of and/or status of a device using<br />

I/O board simulation<br />

2. Converts a third-party protocol to Retail Solutions<br />

I/O Net protocol and interfaces to a custom<br />

cell in Einstein/<strong>E2</strong><br />

2.2.2 MultiFlex Boards<br />

The MultiFlex line of control system boards provides a<br />

wide variety of input, output, and smart control solutions,<br />

all of which are based on a single universal hardware platform.<br />

The board design uses flash-uploadable firmware<br />

and plug-in expansion boards to configure the base platform<br />

board and apply it for use as an input board, relay<br />

output board, analog output board, or a combination I/O<br />

board.<br />

2.2.2.1 MultiFlex 16 Input Board<br />

Figure 2-7 - MultiFlex 16 Input Board<br />

The MultiFlex 16 input board offers sixteen combination<br />

analog/digital input points for use by Retail Solutions<br />

<strong>E2</strong>, Einstein, and REFLECS control systems. The Multi-<br />

Flex 16 may be used in retrofits with no additional hardware<br />

or software setup or upgrades.<br />

The MultiFlex 16 is designed to be 100% compatible<br />

with the previous generation of Retail Solutions input<br />

boards (the 16AI), communicates with the site controller<br />

via an RS485 connection to a REFLECS COM A&D Network<br />

or an <strong>E2</strong> I/O Network. Dip switches on the board set<br />

the network ID (board number) and baud rate.<br />

The board also provides both +5VDC and +12VDC<br />

output voltage points for use in powering transducers or<br />

other input devices that require power.<br />

The MultiFlex 16 has a Hand-held Terminal interface<br />

Section 2.2.4, Hand-held Terminal (P/N 814-3110) that<br />

may be used by technicians to view the input voltage and<br />

engineering unit values for each input point without need<br />

of a voltmeter or front panel controller display.<br />

Table 2-6 shows the part number of the MultiFlex 16.<br />
