J4 SIGNAL

PIN # NAME DESCRIPTION

1 DCD Data Carrier Detect.

From RSC. A positive

voltage is always pro-

vided on this pin to

resolve the external

device's needs if

necessary.

2 RXDATA Receive Data. From

RSC. Serial data is

sent from the RSC to

the external device

through this pin.

3 TXDATA Transmit Data. To

RSC. Serial data is

sent from the external

device to the RSC

through this pin.

4 NC No connection

5 COM Common. Signal

ground.

6 DSR Data Set Ready. From

RSC. A positive volt-

age is always provided

on this pin to resolve

the external device's

needs if necessary.

7 RTS Request To Send. To

RSC. A negative volt-

age on this pin will

prevent the RSC from

sending data to the

external device.

8 CTS Clear To Send. From

RSC. A negative volt-

age on this pin indi-

cates that the RSC is

not ready to receive

data from the exter-

nal device.

9 NC No connection.

LED

There is an LED on the RSC (DS1) that is

used to indicate the operating status of the RSC.

OPERATIONAL DESCRIPTION

LED STATES

which the LED gives its status is as follows:

RSC OPERATING

LED STATE STATUS

On, steady Power is applied, and

the RSC software is

executing.

On, blinking Power is applied, the

RSC software is

executing, and the

RSC is receiving LAN

messages.

Off Power is not applied, or

power is applied and the

RSC has experienced a

fault and has halted

execution.
