Serial Communication

Two serial communication ports are provided by the IQ-400

controller.

•

RS-485: Four wire (twisted pair) interface which is optically

isolated from the controller.

•

Provision for installing a termination resistor is provided.

•

RS-232: At P7 (RS232 DB9 – Real Time Printer Port). At

P2 (RS232 Direct Connect) – standard RS232 interface.

Jumper W6 adds/removes an onboard 120Ω End-of-Line

Termination Resistor.

Power Supply

The IQ-400 controller requires +5VDC for all logic. Relays,

output drivers, etc. require a +12VDC supply. An on-board dc-

dc converter accepts an external voltage source of 10-26VDC,

and converts this unregulated source to the required +5VDC.

For an input voltage range of 10-15 volts, the “+12VDC”

converts this voltage source to the required +12VDC. For more

information, please refer to the ESD power supply installation

manual.

Battery Back-up Requirements

A 12 AH battery is recommended as a back-up to the power

supply, because it is the largest battery that will fit in the

enclosure. The battery should be connected to the power

supply charger in accordance with the manufacturer’s

instructions. Refer to ESD SPS-3.6M2E, or SPS-6.5M4 Power

Supply installation instructions (P/N: SPS36instructions Rev:

04/15/02) for determining battery backup size.

Factory Settings

At the factory the IQ-400 is set as IQ-400 #1, communications

as direct connect (RS232/RS485) @ 9600 baud, with 120 Ohm

resistor termination disabled (W6 jumper set at 1-2).
