Model Abstract 3161-110
The IBM 3161 Model 110 ASCII Display Station provides EIA RS-232-C (CCITT V.24/V.28) interface and Green phosphors CRT.
The 3161 displays up to 1,920 characters, 24 rows of 80 characters each. An alphameric character is represented in an 8x16 contiguous box matrix. The data displayed uses the 128 characters of ASCII/ISO codes and an additional character set containing 24 line drawing graphics, 10 superscript characters and 10 subscript characters. A line drawing character is represented in a maximum 8 x 16 dot matrix to create a contiguous line. The character transmission mode provides the capability to transmit a character over a communication line upon depression of each key. The block transmission mode, selectable at setup time, allows buffered transmission mode of data. The 3161 consists of the three Workstation Elements (Video, Logic, and Keyboard) and Cartridge.
The use of ASCII (ISO) codes and the asynchronous communication interface allows the 3161 to attach to a variety of host processors. Various communication options are selectable by the customer on the setup menu such as line speed (50, 75, 110, 134.5, 150, 200, 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600 and 19,200 bps), parity (none, odd, even, mark, space), interface (EIA RS-232-C (CCITT V.24/V.28), EIA RS-422-A (CCITT V.11)), word length (7, 8-bit), operation mode (echo, character, block mode), turn-around character (ETX, EOT, CR, DC3), line control (CRTS, PRTS, IPRTS), stop bit (1, 2), response delay (0, 100ms) and break signal (170, 500ms). The 3161 provides XON/XOFF Control.
The 3161 has an etched screen, which minimizes glare and fingerprints. Indicators are displayed on the bottom (25th row) of the screen, and provide useful operator information. An audible alarm is provided to alert the operator, and its volume is adjustable by the operator. The video element can be tilted and swiveled by the pedestal to set the screen angle for the operator. The cable-connected keyboard can be moved and its slope is selectable.
Input Editing Capability
Cursor move (up, down, right, left, and home), tab (forward, backward, set and clear), erase (end of line, end of page and entire page), clear (entire page and entire buffer), insert (character and line) and delete (character and line) are provided. Tab erase, insert and delete may be manipulated by field attribute. All characters can be rendered by character or field attributes. A 12-key numeric keypad and 12 Function (F) keys are provided on the keyboard.
Emulation Modes in Features
Additional Read Command (#8001) provides the 3161 US English native mode with complete read command options that 3101 has supported in block mode.
Enhanced 3708 Attachment (#8371) provides the 3161 US English models, attached to a 3708 or 3710 protocol converter, with the enhanced useability on reset key, send/return key, F13 to F24 keys, host and local prints and 25th line access.
Extended Emulation (#8501) provides the enhanced functions such as 24 Definable Function Keys (set by both host and keyboard), 3 PA keys, Local Print Key, 25th Line On/Off Key, Return Setup to Factory Default, Pacing in main port, and Mono/Dual option, in 3101, or five non-IBM emulation modes above.
Five TeleVideo's Emulation (#8901) provides the functions to emulate TeleVideo Models 910PLUS/912/920/925/925E. In addition, it provides the extended functions such as 32 Definable Function Keys (set by both host and keyboard), 3 PA Key, 25th Line On/Off Selection, and Mono/Dual case option.
There are some operational differences such as keyboard layout and how to set up the machine.
The 3161 communicates with a variety of host processors.
When using the EIA RS-232-C (CCITT V.24/28) interface, the 3161 can directly attach to a host processor within 12.2m (40.0 ft) at 50 - 19,200 bps, or can communicate point-to-point to a remote host processor through an external modem.
5841, 5842 and PTT mandatory modems complying with CCITT Recommendation (1979( V.24, V.28, ISO Standard 2110 and either CCITT Recommendations V.21, V.22, V.22 bis or V.23 may be attached. Other non-IBM modems may be attached subject to the Multiple Supplier Systems Bulletin. A modem cable is required for the attachment to a modem. As an alternative to a modem attachment, the 3161 may be directly connected to a ROLM CBX at speeds up to 19.2K bps through one of the following devices with RS-232-C (CCITT V.24/28) interface: ROLMphone Datacom Module (DCM), Data Terminal Interface (DTI), rack-mounted version of the DCM or DTI.
The types and speeds of currently available modems with which the 3161 operates include:
An auxiliary interface is provided for attachment of an input or output device with EIA RS-232-C (CCITT V.24/V.28). The 4201 Proprinter may be attached at the Auxiliary port.
The customer is responsible for preparation of cables. Many IBM systems provide unique cables for 3161 attachment and those systems should be referenced for detail information. A 3m (10 ft) modem cable is provided as an IBM accessory for use in attaching the 3161 to to certain devices (specifically modems). A 1.5m (5 ft) (or 1.2m (4 ft) in EMEA) I/O cable is provided as an IBM accessory for attaching the 4201 or 4201 Proprinter.
The 3161 has an auxiliary port that can connect an ASCII printer over an RS-232-C direct connection. A print key allows local printing of the screen, while the software commands allow remote printing from a host. For example, the 4201/4202 Proprinter may attach via its serial (RS-232-C) interface to the 3161 for direct printing of text-oriented screens (or graphics and text via host programming).
IBM 3101 Compatibility and Migration
The 3161, when operating in 3101 emulation mode, will accept and generate the 3101 model 881 data streams. There are two methods of placing the 3161 into the 3101 emulation mode. The operator may select the 3101 mode during menu setup, or a suitably programmed host may send a "3101 mode" command to 3161. There are some operational differences in terms of the screen management facilities. The 3161/3163 ASCII Display Station Description documents these differences.
A special nondisplayed input mode provides for fields of data to be program-defined so that they will accept data entered from the keyboard without displaying the data on the screen.
