APPENDIX C: ACCESSORIES, ADAPTORS, AND
CABLES
General
Note: On all of the Motorola RJ45 connector heads (except for Ethernet cables), the
numbering of the pins is different than the standard, as shown in the figure below. Pin
1-8 are left to right rather than right to left, as shown below. Therefore, only original
Motorola cables should be used.
This appendix provides the information required for connecting an RTU RS232 port to various
units, as detailed below:
• Connection to a Computer or Terminal (MDLC protocol or User port, USB Device port)
• Connection to a Modem (MDLC protocol or User port)
• Connection to GPS Receiver (Motorola Binary protocol)
• Connecting a User Port to a Printer
• Connecting a User Port to an External Unit
• Connection to a Radio (MDLC and PPP protocols)
• RTU-to-RTU Connection Using MDLC Protocol through RS232 (RS-Link)
• ACE3600 RTU-to-ACE3600 RTU Connection Using MDLC Protocol through RS485
(RS-Link)
• ACE3600 RTU-to-MOSCAD RTU Connection Using MDLC Protocol through RS485
(RS-Link)
• ACE3600 RTU-to-PC Ethernet Port Direct Connection without Hub
• ACE3600 RTU Main CPU to Expansion Module Direct Connection (for systems with I/O
expansion only)
• ACE3600 RTU Main CPU to Expansion Module Connection via LAN Switch - CPU to
expansion LAN switch connection or connection of the first LAN switch to the second, if
such exists (for systems with I/O expansion only)
• ACE3600 RTU Main CPU to Expansion Module Connection via LAN Switch - LAN
switch to expansion module connection (for systems with I/O expansion only)
