Appendix E, Enhanced serial port communication protocol
MECHANICAL CONNECTIONS
To fasten a laptop or other computer running a standard serial program to the serial port of the
ENHANCED REMOTE PANEL you must use following hardware connections.
RS-232 MECHANICAL CONNECTIONS
The connections to the ENHANCED REMOTE PANEL are at the rear of the unit on a standard
9-pin "D" connector labeled J16. Only a 3-wire protocol is supported.
J16 - pin - 3 = Transmit
J16 - pin - 2 = Receive
J16 - pin - 5 = Ground
A null modem cable is required to connect between the Computer’s RS232 serial port and the
Monitor’s Enhanced Remote Panel. The following diagram shows how to construct the RS232
cable used to connect with the Enhanced Remote Panel’s J16. J16 is a DB9 female connection
on the back of the Enhanced Remote Panel.
RS-422 MECHANICAL CONNECTIONS
The connections to the ENHANCED REMOTE PANEL are at the rear of the unit on a standard
15-pin "D" connector labeled J17. Only a 4-wire protocol is supported.
J17 - pin - 3 = Receive-A
J17 - pin - 15 = Receive-B
J17 - pin - 2 = Transmit-A
J17 - pin - 14 = Transmit-B
J17 - pin - 1 = Shield Ground
Note that RS-422 communication is also at 9600 baud and it requires using 2 stop bits.
