Provides character pacing in units of milliseconds for all of the data
specified. The range of the pacing is from 1 to 31 milliseconds. Pacing
greater than 31 milliseconds defaults to the maximum (31 ms).

Supports RS-485. However, a specific protocol for defining the
mechanism as to when a device is permitted to transmit on the RS-485
bus must be followed. To use this feature, use RS-422 communications
settings. Set hardware handshaking to none. The RTS output can now
be used to enable the transmitter. Notice that the receiver is always
active. Therefore, transmissions are also received.
Physical Description
The CEN-COM is housed in a black enclosure with silk-screened labels on the front
and rear panels. On the front of the unit there are 13 LEDs for indicating the unit’s
current status. All connections, except for the Ethernet connection, are made on the
back of the unit. Refer to the physical views shown below. There are four rubber feet
on the base of the unit for stability and to prevent slippage.
