Device Addressing
Every SymNet hardware device must be uniquely identified within its ring. A device address of 1 through 16 is available.
Address 1 is considered the master unit, all others are slaves. If a device is assigned an address of 1, its DIP switch #2 “SLAVE
/ MASTER” must be in the “MASTER” position. If a device is assigned an address other than 1 (2-16), its DIP switch #2 must be
in the “SLAVE” position. The device addresses of the physical hardware in your system must match the devices as configured in
your SymNet Designer Site File. You may use the pictorial diagrams below to quickly set up and understand the device address
DIP switches on the DigIO.
Note:
Any time the DIP switches are changed, the unit(s) must be power cycled for the changes to take effect.
Host Communications
The host PC (running SymNet Designer) can communicate directly with the DigIO as a stand alone or ring master unit (Ring
#1, Address #1) in one of two ways: RS-232 or Ethernet. Otherwise, the host PC communicates with the DigIO indirectly via the
SymLink bus like any other slave hardware device.
RS-232:
The DigIO has only one RS-232 port on the rear of the unit, a slight departure from the rest of the SymNet line. As a result, this
rear panel RS-232 port sees double duty as both a host PC interface or a 3rd party RS-232 accessory controller interface, but
not both simultaneously. The port’s purpose is set by DIP switch #9 labeled “RS-232: ACC / HOST”. When this switch is set
to the “HOST” position, DIP switch #1 determines the baud rate of the RS-232 port (57.6 or 115.2 kilobaud) and this baud rate
must match the baud rate chosen in SymNet Designer’s Preferences dialog. When DIP switch #9 is set to the “ACC” position,
the RS-232 port’s baud rate defaults to 38.4k unless changed by the RS-232 Control Protocol or SymNet Designer’s Upgrade
Firmware dialog.
Ethernet:
The DigIO’s 10/100 Base T Ethernet port is available for use regardless of DIP switch #9’s position provided that the DigIO is
the master unit in a single ring system (device address of Ring #1, Address #1). If for some reason, the DigIO can not be made
the master unit in a single ring system, the host PC must connect via RS-232 to the master unit. In a multi-ring system, Ethernet
interfacing is done through the CobraLink which also has an Ethernet interface (CobraNet) and must be the ring master.
Note:
Ethernet communications settings (IP addresses and access codes) must first be set up from SymNet Designer via the
RS-232 port interface. Please see the SymNet Designer online help for further information.
DigIO DIP Switch Settings
NOTE:
For the sake of space, a small variety of configurations are shown.
A total of 16 devices per ring are possible. Or, in a multi-ring system,
one CobraLink and 15 other devices per ring.
