interface. This port is jumper selectable as a RS-
232C port or a RS-485 port depending on the needs
of the feed. The data bits, stop bits, and baud rate
are all configurable (see section 3 for details).
2.3 Coe CPEC/BG1 Interface
The connection to a Coe CPEC or BG1
Electronic Feed is as follows:

Notes:
‚ The communication should be set for 9600
baud, 7 data bits, odd parity, 2 stop bits.
‚ The feed length and speed thumb wheels must
be set at zero or the settings from the serial port
will be ignored.
‚ Due to the operation of the feed controller, the
present feed length and speed are held in the
OmniLink 5000 OIT. These settings are
displayed in the feed screen without requesting
any data from the feed controller. This is
necessary because the feed controller must be
halted (any feed in progress stops) in order to
request present settings. When a new feed
length or speed is entered, the feed controller is
halted, the setting is transmitted to the
controller, the new setting is requested for
verification with the desired value, the feed
controller program is re-initiated, and the
present setting is updated in the OmniLink 5000
OIT. Failure of the feed to return the same
setting as transmitted will cause the display to
show zeros for that parameter if the old
communications board is installed, or to give a
communications error status in the feed screen
for the new communications board. When this
interface is first installed, the present settings
will not be initialized and may indicate any
setting.
