Pin 21 - Ground for Serial communication
Serial Communication Output Available
Logic level TTL Non-isolated Serial Output. To communicate
with PC’s, use the external Texmate logic to RS232 Isolated
Converter.
SERIAL COMMUNICATION PINOUTS
Choose only one type of serial communication per module.
Component Side
Output options include up to four heavy duty, high isolation 5 and
10 amp relays that can be programmed individually to operate in
any desired manner. An independently programmable analog
output is available that can be user configured for 4-20mA, 0-
20ma or 0 to 10VDC. The isolated serial output is available as
RS-232C or RS-485. All or any combination of these options may
be combined on one module. The above illustration shows a fully
loaded Output Module with RS-232C Serial Communication. If
any one of the output options is not included, the components
are simply not placed.
