since last reset, transmit errors, network transmit buffer count and status of the network
packet receive queue are shown.
Pressing "4" displays a list of the connections currently hosted by the module by IP
address. For each session, internal module/port connections in the transmit and
receive directions are shown if they exist. Also, an indication is given for whether or
not a connection can send and receive data on the network and on the internal bus. TX
data flow is data in the module's outbound direction, RX data flow is data in its inbound
data direction. In cases where data is not being received at a destination, this screen can
help determine the source of a problem. For example, if a workstation is attempting to
send data to an RS-232 device connected to a V74 which has handshook its port
connection, a user can identify this situation by noting that Bus Data Flo is set to "no" in
the TX direction.
V74/V75/V87 OPERATION
V74/V75/V87 USER-PROGRAMMABLE FEATURES
The V74/V75/V87 can be programmed to operate in one of three reporting modes.
Other programmable features include the serial port configuration and device name
for each individual port, the host module location, the message terminating character,
and time tag. These features are programmed by accessing the menu-driven
configuration mode from the host module or service port. All features can be
programmed from the front panel of units equipped with LCD and control panel.
V74/V75/V87 SERIAL PORT CONFIGURATION
The V74/V75/V87 module translates data for devices using different serial
configurations. You can set the baud rate, word size, stop bits, parity and
XON/XOFF handshaking for each port. Factory default configuration on serial ports
is 9600 baud rate, 8 bit word size, 1 stop bit, no parity and XON/XOFF disabled.
V74/V75/V87 PORT DEVICE NAME
You can assign individual names to each port for reference while the unit is in
configuration mode or port message/data identification. Factory default is Device A
for Port 1, Device B for Port 2, Device C for Port 3, and Device 4 for Port 4.
V74/V75/V87 HOST MODULE LOCATION
An M Series unit can have multiple host modules installed on a single unit or multiple
units. You can program the V74/V75/V87 module to send messages to any individual
host module on a single unit. The host module location consists of the M Series unit
