Analog outputs automatically set the output voltages to 0 V if too much time elapses
after the last Poll Command message received by the device. At this timeout
condition, the output of the generator shuts off and goes safe.
DEVICENET ROTARY SWITCHES: BAUD RATE AND ADDRESSING
The DeviceNet interface features three rotary switches, located on the rear, which are
read each time the DeviceNet interface powers up. Use the Data Rate switch to select
a baud rate: 125, 250, or 500 kbaud (0 = 125;1 = 250; 2 = 500 kbaud). The default is
500 kbaud. A switch setting in the PGM region lets you configure the baud rate
through DeviceNet.
The signals available at the RS-232, AE Bus Host port conform to the RS-232
interface standards. Each generator is factory preset for a baud rate of 19.2 kb and
Address 1. Table 4-4 describes the RS-232, AE Bus Host pin signals.

Use the MSD and LSD switches to select the unit’s address (MAC ID). MAC IDs 0
through 63 are valid. Use the MSD switch to select the MAC ID’s most significant
digit; use the LSD switch to select the MAC ID’s least significant digit. Switch
settings greater than 63 (or in the “PGM” region of the MSD switch) let you configure
the MAC ID through DeviceNet.
DEVICENET CONTROL PANEL LEDS
The rear panel of the Apex generator features two, bi-color LEDs (see Figure 4-20).
One is labeled MOD and indicates module status. The other is labeled NET and
indicates network status.
Devicenet Module Status LED
The MOD bi-color (amber/green) LED provides device status. It indicates whether the
device has power and is operating properly. Table 4-14 shows the LED’s various
states and meanings
