CHAPTER 1 - OPERATION
The Patton 3060/V24 (MD-V.24/TCB) is a network enhancement accessory intended for high
speed synchronous or asynchronous RS-232 modem, or port sharing applications. The 3060/
V24 (MD-V.24/TCB) allows for immediate expansion of a system without the requirement of
additional communication lines. The 3060/V24 (MD-V.24/TCB) allows any combination of up
to six RS-232 DCE or DTE devices to share a single RS-232 DCE or DTE high speed link in
a point-to-point or multi-point polled network.
Channel Clocking
The Patton 3060/V24 (MD-V.24/TCB) is protocol transparent and operates in synchronous
and asynchronous environments at data rates up to 76,800bps, depending on cable length
and attached equipment. Clocking can be derived from the Master Port clock, (pins 15 or 24
for TXC and 17 for RXC), the internal clock generator or any Sub-Channel clock, (pins 15 or
24 for TXC and 17 for RXC).
Fallback Clocking
In the event of loss of an externally provided clock or optionally Sub-Channel 1 DCD becoming
inactive, the 3060/V24 (MD-V.24/TCB) has the ability to automatically fall back to the
predetermined internal baud rate clock or the Sub-Channel 6 RX Clock (pin 17).
Channel Interface
The 3060/V24 (MD-V.24/TCB) has seven DB-25 female connectors located on the rear of the
unit. Each port is DCE/DTE selectable, which eliminates the need for crossover cables. DSR
or DTR can additionally be forced to the active state individually on each Sub-Channel by
Jumper control.
