Communication Links; Rs232 Ports - Motorola V186 - Cell Phone - GSM System Planner Manual

Communication Links

The system may support a network comprised of a nearly unlimited number of links. The
RTU supports a variety of communication media, protocols and data speeds, as detailed
below:
• Serial RS232 ports, up to 115.2 kbps, supports:
– Local PC using MDLC (MDLC or User Protocol)
– RTU to RTU (MDLC)
– External Data (MAS) radio (MDLC, ModBus RTU, DF1 or user protocol)
– External Wire-line modem (MDLC, ModBus RTU, DF1 or user protocol)
– External Dial up modem PSTN or Cellular (MDLC)
– External Cellular packet data modem (MDLC/PPP)
– Astro Digital Trunk Radio (IV&D) XTL5000/XTS2500 (MDLC/PPP)
– TETRA MTM700/MTM 800 Radio (MDLC/PPP)
– Third party PLC/Device (ModBus RTU, DF1 or user protocol)
– GPS receiver interface
The ACE3600 supports RS232 links to standard modem over PPP on the built-in serial
ports and on the plug-in ports. These ports may be connected to an external modem
supporting AT commands.
• RS-485 ports, multi-drop 2-Wire up to 460.8 kb/s, supports:
– RTU to RTU on multi-drop connection (MDLC).
– Third party PLC/Device on multi-drop connection (ModBus RTU or User
protocol).
• Ethernet port, up to 100 Mbps, supports:
– Local PC using MDLC (MDLC over IP or User Protocol on TCP/IP)
– RTU to RTU (MDLC over IP)
– Third party Device (User Protocol on TCP/IP)
• Radio modem port, supports:
– Conventional radio – DPSK 1.2 kbps, FSK 2.4 kbps, DFM 2.4/3.6/4.8
kbps, Duobinary 9.6 kbps (MDLC)
– Analog Trunked radio - DPSK 1.2 kbps (MDLC) - See the list below.

RS232 Ports

On ACE3600 CPU modules, Serial Port 1 and Serial Port 2 (SI1 and SI2) are RS232
ports. Additionally up to two RS232 Plug-in ports can be installed on the CPU module
(on PI1 and PI2 plug-in ports). The RS232 ports can be configured to Async or Sync
operation mode and they enable local connection of a PC with the ACE36000 STS to the
RTU, direct connection of another RTU, connection of modems, digital radios, data
radios, third party PLCs and other devices. In addition, the ACE3600 supports RS232
links to standard modem over PPP on the built-in serial ports and on the plug-in ports.
These ports may be connected to an external modem supporting AT commands (refer to
