Table 4 below lists the U4600 front-panel connectors, their types and pinout information.
2.4 Serial Port Configuration
Device
assignments
The U4600 has one external serial port. A “device” must be assigned once to the serial
port, but no “device” may be assigned more than once. In addition, more than one device
may be assigned at one time but only one device which accepts input may be assigned. (If
multiple devices are assigned to the serial port, the port’s settings are controlled by the
device with higher priority according to the list below.) Device port assignment and device
configuration (see below) may be controlled only from the unit front panel and the network
may disable this capability. The possible devices are:
1. Terminal
2. Modem (“modem” being remote terminal via modem)
3. Local COMPEL
4. Auxiliary Data
5. Printer (including COMPEL
e-mail and reports)
Device
configurations
When a serial port configuration command is received, the specified configuration is
immediately stored for the specified device (e.g. for the “Terminal” device). If a serial port
is currently assigned another device, then its output buffer is immediately flushed and the
port re-configured. Communication is fixed at 1 start, 1 stop, and 8 data bits, with no hard-
ware handshaking. No provision for software handshaking is made in this Release. The
serial port’s behavior for each of its device types is described in the following table.
