3012-14-18/V24 PATTON ELECTRONICS CO. INSTALLATION AND OPERATIONS MANUAL 137001UA CHAPTER 1 - OPERATON The Patton MSDs are network enhancement accessories intended for DCE sharing applications. The Patton MSDs allows up to eight terminals or DTE devices to share a single point to point or multi-drop polled communication link. The Patton MSDs allow for immediate expansion of a system without the requirement of additional Modems or communication lines.
PATTON ELECTRONICS CO. 3012-14-18/V24 INSTALLATION AND OPERATIONS MANUAL 137001UA Channel Selection Modes (4 and 8 port only) The Patton MSD provides two selectable sub-channel service modes of operation: Scanning Mode and Priority Mode. Depending on system requirements, either mode may be selected by internal DIP switch settings. Both modes switch on activity from the sub-channel. Activity is defined as raising RTS on a sub-channel.
PATTON ELECTRONICS CO. 3012-14-18/V24 INSTALLATION AND OPERATIONS MANUAL 137001UA Front Panel Indicators and Switches The front panel LED indicators associated with each sub-channel identify the active port. A green POWER ON LED indicates when AC voltage is applied. Two adjacent green LED indicators illuminate in union with individual port activity and identify Transmit Data (TXD) and Receive Data (RXD) activity. Positive latching type switches are provided for each DTE port.

3012-14-18/V24 PATTON ELECTRONICS CO. INSTALLATION AND OPERATIONS MANUAL 137001UA Installation Select an appropriate location accessible to and within six feet of an AC power outlet. The outlet must have a ground pin receptacle for product warranty. The DCEto-DTE cabling between each attached device and the MSD should be “Straight Through”, shielded and terminated with male DB-25 connectors. Sub-Channels are marked “PORT 1” through “PORT 8”; the Master Port is marked “MASTER”.

To select Scanning Mode, set switch position 5 to OFF OFF. The Modem connected to the master port of the MSD must toggle CTS in response to RTS for the MSD to operate correctly. In addition, the terminals connected to the ports must toggle RTS to gain control of the unit.
